1. la señora Treviño tiene el doble de edad que su
hijo hace 9 años la suma de su edades era 30
¿cual es su edad actual?
Answer:
Daughter age = x = 16 years old
Mother's age = 2x = 2 × 16 = 32 years
Step-by-step explanation:
The computation of their current age is shown below:
Let us assume that the current age of the daughter is x
And, the current age of the mother be 2x
Now nine years ago, their ages would be
daughter age is x - 9
And, the mother age would be 2x - 9
Now the equation would be
x - 9 + 2x - 9 = 30
3x - 18 = 30
3x = 30 + 18
3x = 48
x = 48 ÷ 3
x = 16.
Therefore
Daughter age = x = 16 years old
Mother's age = 2x = 2 × 16 = 32 years
Solve for this equation: 500:10||x:50
x=10 and pls give me a thanks

Let E be the event that a corn crop has an infestation of ear worms, and let B be the event that a corn crop has an infestation of corn borers. Suppose that P(E) = 0.24, P(B) = 0.16, and P(E and B) = 0.13. Find the probability that a corn crop has either an ear worm infestation, a corn borer infestation, or both.
a. 0.53
b. 0.13
c. 0.6
d. 0.27
Answer:
d. 0.27
Step-by-step explanation:
Calculation to determine the probability that a corn crop has either an ear worm infestation, a corn borer infestation or both
Using this formula
P(E U B) = P(E) +P(B) -P(E n B)
Let plug in the formula
P(E U B) =0.24 + 0.16 -0.13
P(E U B)=0.27
Therefore the probability that a corn crop has either an ear worm infestation, a corn borer infestation or both will be 0.27
Martin is an after-school math tutor. He noticed that 6 people still needed help and only Two-fifths of the tutoring session time was left. Since each person is to be given an equal amount of time, Martin wrote the expression below to find the fraction of the tutoring session each person who still needed help would be allotted.
Two-fifths divided by 6

Use the given x and y values to write a direct variation
equation.
x = 5, y = 25
Answer:
k= 1/5
Step-by-step explanation:
x is proportional to y
x = ky (k is const.)
k = x/y
k= 5/25
k = 1/5
Answer:
Equation of direct variation is : [tex]\mathbf{y=5x}[/tex]
Step-by-step explanation:
We are given: x= 5 and y=25
We need to write equation of direct variation.
The formula for direct variation is: [tex]\mathbf{y=kx}[/tex]
So, if y=25 and x=5, k will be:
[tex]y=kx\\25=k(5)\\k=\frac{25}{5}\\k=5[/tex]
So, equation of direct variation is : [tex]\mathbf{y=5x}[/tex]
The total length of wires A,B and C is 445cm. Wire A is 45cm longer then wire B,and wire B is half as long as wire C. How long is wire A?
Answer:
A = 145cm
Step-by-step explanation:
A+B+C = 445cm
b = 1/2c
a = b+45 = 1/2c + 45
445 = c + (0.5c) + (0.5c + 45)
445 = 2c + 45
445 - 45 = 2c
400/2 = c
c = 200cm
a = 1/2c + 45 = 1/2*200 + 45 = 100 + 45 = 145cm
Mrs canales class is selling pizza to earn money for a field trip. For every pizza sold the class makes $5.35. They have already earned $182.90 toward their $750 goal. How many more pizzas must they sell to earn $750 (algebraic approach) Thanks
Answer:
They still have to earn:
$750 - $182.9 = $567.1
and if they make $5.35 for every pizza sold:
$567.1 : $5.35 = 106
They must sell 106 pizzas more.

Answer:
y = 5
General Formulas and Concepts:
Alg I
Point-Slope Form: y - y₁ = m(x - x₁)
x₁ - x coordinate y₁ - y coordinate m - slopeStep-by-step explanation:
Step 1: Define variables
Point (-2, 5)
Slope m = 0
Step 2: Write function

the answer is 4) i think
Step-by-step explanation:
i'm not sure but what i know, if the base is the same number, u can just add the power. for example, the bases is the same number which is x, so u can just solve the power which 3/4 + 1/5 then u get answer.

(8,9), X + 8y = 9
Help me please
Answer:
slope of -1/8
and it crosses:
(3,5)
.
Plug the above data into the "point-slope" form:
y - y1 = m(x - x1)
y - 5 = (-1/8)(x - 3)
y - 5 = (-1/8)x + 3/8
y = (-1/8)x + 3/8 + 5
y = (-1/8)x + 3/8 + 40/8
y = (-1/8)x + 43/8

P(x) + Q(x) = 4x^2 + 6x - 9 -7x^2 - 12x +8
x^2 terms: 4x^2 - 7x^2 = - 3x^2
x terms : +6x - 12x = - 6x
linear term: - 9 + 8 = - 1
Answer: -3x^2 - 6x - 1

Answer:
a. 17.80 b. 71.20
Step-by-step explanation:
I used to hate percents. Let me teach you a trick:
take the og value (89) and multiply it by the percentage (20% or 0.2). Then once you have that answer (17.80), subtract it from the og value (89-17.80). That's your answer for how much you still owe! (71.20)

A bookcase has 5 of these bookshelves that are 42 inches long. How many FEET of shelf space is there? Explain your reasoning. (If the answer is given in inches you can only get a 4 out of 6 maximum. How many FEET of shelf space is the answer you explain.) *
Answer:
[tex]17.5\ \text{feet}[/tex]
Step-by-step explanation:
A bookcase has 5 bookshelves. Each bookshelf is 42 inches long.
Total bookshelf length in the book case = [tex]5\times 42=210\ \text{inches}[/tex]
[tex]1\ \text{feet}=12\ \text{inches}\\\Rightarrow 1\ \text{inch}=\dfrac{1}{12}\ \text{feet}[/tex]
[tex]210\ \text{feet}=210\times \dfrac{1}{12}=17.5\ \text{feet}[/tex]
The bookcase has a total shelf space of [tex]17.5\ \text{feet}[/tex].
*One bookshelf has a space of [tex]\dfrac{42}{12}=3.5\ \text{feet}[/tex].

1. Francisco invested $5,000 into an account that earns 3% compounded quarterly. How many
times will Francisco earn interest after keeping the money in the account for 5 years?
2. What will be the value of his account in 5 years if he does not make any additional deposits or
withdrawals?
3. After how many years will Francisco’s account reach $10,000
4. If Francisco wanted to double his money in 12 years, what Interest rate would his account have to earn?
Answer:
10,002.21
Step-by-step explanation:
1)4x5= 20 times
2) principal= 5000
interest rate per year= 3%
compounded times per year=4
time in years = 5
the formula is amt= p*(1+r/n)^(n*t)
thus
Amount = 5805.92
3) If time in years = 23.2
then
amount = 10,002.56
4) Principal = 5,000
interest rate per yr= 5.82%
Compounded times per year = 4
time in years =12
