Answer:
x=30
Step-by-step explanation:
You have to isolate for x. This means you need to somehow get x on one side of the equation all alone. In this case it is x-9=21 which means some unknown number x with 9 subtracted from it is equal to 21. When we bring the -9 over to the other side to get the x all alone, we have to switch the sign of the -9 so it becomes +9. This means x=21+9, and if you add that you'll get 30!

Frank weighs 160 pounds and is on a diet to gain 2 pounds a week so that he can make the football team. John weighs 208 pounds and is on a diet to lose 3 pounds a week so that he can be on the wrestling team in a lower weight class. If Frank and John can meet these goals with their diets, when will they weigh the same, and how much will they weigh at that time? (Hint: Solve for x and y and make sure you write a complete sentence for an answer)
Answer: If Frank and John can meet these goals with their diets , they will weigh same after 9.6 weeks and they will weigh 179.2 pounds.
Step-by-step explanation:
Let x = Number of weeks.
As per given question ,
Weight of Frank after x weeks = 160+2x (pounds)
Weight of John after x weeks = 208-3x (pounds)
When Weight of Frank= Weight of John
Weight of Frank after 9.6 weeks = 160+2(9.6) = 179.2 pounds
Weight of John after 9.6 weeks = 208-3(9.6)=179.2 pounds
Hence, If Frank and John can meet these goals with their diets , they will weigh same after 9.6 weeks and they will weigh 179.2 pounds.
if 3.142×110 = 345.62, why is the decimal point not infront of the 5?
Answer:
It is not infront of the 5 because when mutiplying it goes above a whole number so the . has to move back.
Step-by-step explanation:
Answer:
It has to be in front of the 5 since you have to move the decimal 2 places to the right and it lands beside the 5

Jim and bill each invest $15,000 into savings accounts that earn 3.5% interest. Jims account earns simple interests and bills account earns compound interest. After 25 years, who will earn more interest and how much more will he earn.
Answer:
Bill will earn more interest
He will earn $ 20,448.67 from his investment
Step-by-step explanation:
Firstly let us calculate Jim's earnings based on simple interest
A = P(1 + rt)
Calculation:
First, converting R percent to r
a decimal
r = R/100 = 3.5%/100 = 0.035 per year.
Solving our equation:
A = 15000(1 + (0.035 × 25)) = 28125
A = $28,125.00
The total amount accrued, principal plus interest, from simple interest on a principal of $15,000.00 at a rate of 3.5% per year for 25 years is $28,125.00 for Jim
Now let's us calculate bill's investment based on compound interest
Equation
A = P(1 + r)^t
A=15000(1+0.035)^25
A=15000(1.035)^25
A=15000*2.36324498427
A = $ 35,448.67
We see that Bill will earn
$ 20,448.67 from his investment

find the unknown angle mesure
Answer: 1=65° and 5=43
Step-by-step explanation:
Question 1:
Angles on a straight line always add up to 180°.
So to find the angle of x on the first question you have to do 180-115=65°
You would have to use this method for questions 2, 3 and 4 as well.
Question 5:
Right angles always add up to 90° so to work out what x is you would have to do 90-47=43
You would have to use this method for questions 6, 7 and 8.
Hope this helps :)
i need help what is x?
Answer:
square root of 109
Step-by-step explanation:
Use the Pythagorean Theorem to find x. The equation is a^2+b^2=c^2. In this case, a=3, b=10, and c=x. Plug that into the equation to get 9+100=c^2. Simplify that to get 109=c^2. Then divide each side by squared to get square root of 109=c.

A deposit of $10,000 is made in a trust fund that pays 3.8% interest, compounbed quarterly. It is specified that the balance will be given to Abudu Charity after the money has earned interest for 40years. How much will the charity receive?
9514 1404 393
Answer:
$45,395.39
Step-by-step explanation:
The formula for an amount earning compound interest is ...
A = P(1 +r/n)^(nt)
where principal P is invested at annual rate r compounded n times per year for t years.
Using the given numbers, we have ...
A = $10,000(1 +0.038/4)^(4·40) ≈ $45,395.39
The charity will receive $45,395.39.

Step-by-step explanation:
Corresponding sides are in proportion, that is

4x = 21.6 ( divide both sides by 4 )
x = 5.4

Step-by-step explanation:
helo?
Answer:
x = $11
Step-by-step explanation:
5x = $55
9x = $99
2x = $22
In order to find the relationship between x and y, all we have to do is divide y by the term.
$55 ÷ 5 = 11
$99 ÷ 9 = 11
$22 ÷ 2 = 11
Therefore, each ticket sold is $11, or x = $11

Answer:
41.29 cm²
Step-by-step explanation:
From the question,
Area of the shaded portion = Area of the circle - area of the square.
A' = πr²-L²...… Equation 1
Where A' = Area of the shade portion, r = radius of the circle, L = length of the square, π = pie
Given: r = 4 cm, L = 3 cm
Constant: π = 22/7.
Substitute these values into equation 1
A' = [(22/7)×4²]-3²
A' = 50.29-9
A' = 41.29 cm²
Hence the area of the shaded portion is 41.29 cm²
Independent = cups of milk poured Dependent = Milk left in the gallon jug Independent = Milk left in the gallon jug Dependent = cups of milk poured
Answer:
Independent = Milk left in the gallon jug
Dependent = cups of milk poured
Step-by-step explanation:
In an experiment or a research, a variable is defined as the thing or a phenomenon that you are trying to found out or measure. Variables can be independent variable as well as the dependent variable.
Independent variable is the variable that the researcher or the experimenter can change or manipulate in the research. This variable does not depend on others and thus stands alone. Its value can be change or altered to find the changes in the dependent variables. They are used as treatment variables.
Whereas, the dependent variables are those variables that are dependent on the values of the independent variables. It is considered as the effect of the independent variable. An independent variable is often manipulated to measure the outcome in the dependent variable.
In the context, the cups of milk poured is the dependent variable and the independent variable is the amount of milk left in the jug.
what is the value of x in the equation 3(2x + 8) =0
Answer:
x=-4
Step-by-step explanation:
1. Distribute
3(2x+8)=0
6x+24=0
2. Subtract 24 from both sides.
6x+24=0
6x+24-24=0-24
3. Simplify
6x=-24
4. Divide both sides of the equation by the same term
6x=-24
[tex]\frac{6x}{6}[/tex] = [tex]\frac{-24}{6}[/tex]
5. Simplify
x=-4
And thats the answer.

Here are five sums. Use the distributive property to write each sum as a product with two factors. 2+7 5−10 −2^2 +++ 2−1/2
Question:
Here are five sums. Use the distributive property to write each sum as a product with two factors.
[tex](a)\ 2a + 7a[/tex] [tex](b)\ 5z - 10[/tex] [tex](c)\ c - c^2[/tex] [tex](d)\ r + r+ r+ r[/tex] [tex](e)\ 2x - \frac{1}{2}[/tex]
Answer:
[tex](a)\ 2a + 7a = 9a[/tex]
[tex](b)\ 5z - 10 = 5(z - 2)[/tex]
[tex](c)\ c - c^2 = c(1 - c)[/tex]
[tex](d)\ r + r + r + r = 4r[/tex]
[tex](e)\ 2x - \frac{1}{2} = \frac{1}{2}(4x - 1)[/tex]
Step-by-step explanation:
Required
Apply distributive property
[tex](a)\ 2a + 7a[/tex]
Apply distributive property [Factor out a]
[tex]2a + 7a = a(2 + 7)[/tex]
[tex]2a + 7a = a(9)[/tex]
Open bracket
[tex]2a + 7a = a*9[/tex]
[tex]2a + 7a = 9a[/tex]
[tex](b)\ 5z - 10[/tex]
Express 10 as 5 * 2
[tex]5z - 10 = 5z - 5*2[/tex]
Apply distributive property [Factor out 5]
[tex]5z - 10 = 5(z - 2)[/tex]
[tex](c)\ c - c^2[/tex]
Express c as c * c
[tex]c - c^2 = c - c * c[/tex]
Apply distributive property [Factor out c]
[tex]c - c^2 = c(1 - c)[/tex]
[tex](d)\ r + r+ r+ r[/tex]
Express r as r * 1
[tex]r + r + r + r = r * 1 + r * 1 + r * 1 + r *1[/tex]
Apply distributive property [Factor out 1]
[tex]r + r + r + r = r(1+1+1+1)[/tex]
[tex]r + r + r + r = r * 4[/tex]
[tex]r + r + r + r = 4r[/tex]
[tex](e)\ 2x - \frac{1}{2}[/tex]
Express 2x as 4x/2
[tex]2x - \frac{1}{2} = \frac{4x}{2} - \frac{1}{2}[/tex]
Apply distributive property [Factor out 1/2]
[tex]2x - \frac{1}{2} = \frac{1}{2}(4x - 1)[/tex]
