I'll mark u as brainliest pls help with these 2 questions
Answer:
3, 10
Step-by-step explanation:
1.
5x-1=14 ->
5x=15 ->
x=3.
2.
15+3x=45 ->
3x=45-15=30 ->
3x=30 ->
x=10.
Hope that help! :)
Answer:
1.) x=3
2.)x=10
Step-by-step explanation:
for the first problem you would add 1 to both sides, and you would get 5x=15, then you would divide both sides by by 5 to get x by itself. 5x/5=x and 15/5=3, so x=3. you can also plug it in. 5(3)-1=14
for the second one you wpuld subtract 15 from both sides, and you would get 3x=30. divide both sides by 3 which is x=10. plug it in, 15+3(10)=45.
I need help with these 3 questions. No links, please.
Answer:
Q9: C.
Since each smaller line counts as 1/5, you can simply start from the point 1 and count 3 times to reach D.
[tex]3*\frac{1}{5} =\frac{3}{5}[/tex]
Since you started at 1, you can add [tex]1+\frac{3}{5} =1\frac{3}{5}[/tex]
Q10: B
We can subtract/ignore 3 from all of them to make things simpler.
Now, we need to find the lowest value to greatest from:
[tex]\frac{5}{8}, \frac{7}{16} ,\frac{1}{2}[/tex]
In order to compare these, we make the denominators the same (in this case: 16)
[tex]\frac{5}{8} =\frac{5*2}{8*2} =\frac{10}{16}[/tex]
[tex]\frac{7}{16} =\frac{7}{16}[/tex]
[tex]\frac{1}{2} =\frac{1*8}{2*8} =\frac{8}{16}[/tex]
Since 7 is the smallest value, followed by 8 and lastly 10,
the smallest to greatest in order would be
[tex]\frac{7}{16} ,\frac{1}{2} ,\frac{5}{8}[/tex] (B)
11: C
If you look at both [tex]\frac{2}{4}[/tex] and [tex]\frac{5}{8}[/tex], they are not directly above one another. Hence, they are not equal.

Answer:
A' (9, - 1 )
Step-by-step explanation:
Using the translation rule
(x, y ) → (x + 6, y - 3 ) , then
A (3, 2 ) → A' (3 + 6, 2 - 3 ) → A' (9, - 1 )

simple question just to lazy to really think about it!
Jose runs 6 miles in 44 minutes. At the same rate, how many minutes would he take to run 9 miles?
Answer:
66 minutes
Step-by-step explanation:
Step 1: Divide 44 minutes divided by 6 miles.
[tex]\frac{44}{6}[/tex] [tex]\frac{22}{3}[/tex] [tex]7\frac{1}{3}[/tex]Step 2: Multiply 9 by 7 1/3.
[tex]9*7\frac{1}{3}[/tex] [tex]9*\frac{22}{3}[/tex] [tex]3*22[/tex] [tex]66[/tex]Therefore, the answer is 66 minutes.

Keith wants to buy an IPad for $500. He wants to earn enough money delivering pizzas to cover at least two-fifths of the cost.
Part A.
If he earns $12.50 per hour at work, write an inequality that represents how many hours Keith's needs to work
Part B
Solve your inequality? Justify your answer.
Answer:
Step-by-step explanation:
500 / 5 = 100 (that's 1 fifth, so 2 fifths will be 200)
200 / 12.5 = 16 (he will have to work 16 hours to get $200)
the inequality would be:
x * 12.5 >= 500 * 0.4 (something like that)

Naomi's square bedroom
has an area of 90 square feet. What is
the length of one of the walls? Round to the nearest tenth if
necessary. ( The answer is 9.5 but how to you get there ?)
Think of a number, that when multiplied with itself, will get you 90.
We could try something like 7. So 7*7 = 49, but it's too small.
How about 10? Well we get 10*10 = 100 which is too big. The answer is between 7 and 10.
Let's try 8. So we get 8*8 = 64 which is too small.
This process is repeated until you determine that the answer is somewhere between 9 and 10
9*9 = 81
10*10 = 100
----------------
From here, we can try 9.5 since it's right between 9 and 10
9.5*9.5 = 90.25
close but not quite there. It's a bit too large. So the actual value is somewhat smaller than 9.5
Let's try 9.4
9.4*9.4 = 88.36
That seems even worse off compared to 90.25, so 9.5 is the better answer.
-----------------
As a shortcut, you can use the square root on your calculator
[tex]\sqrt{90} \approx 9.4868 \approx 9.5[/tex]

Answer:
C. .45
Step-by-step explanation:
Think of it like this: that is 45 hundredths and you are trying to find what 45% is and it is like 45/100 so .45 is your answer.
answer c=0.45
0.45 is equal to 45%.

Which expression is equivalent to 24 x 2 - 22 x + 5? A(8 x - 5)(3 x - 1) B (8 x + 5)(3 x + 1) C(12 x - 5)(2 x - 1) D (12 x + 5)(2 x + 1)
Answer:
C) (12x-5)(2x-1)
Step-by-step explanation:
12x multiplies 2x to give 24x²
then 12x multiply -1 to give -12x
then -5 multiply 2x to give -10x
then -5 multiply -1 to give 5
that will be 24x²-12x-10x+5
our and =24x²-22x+5
If the line passing through points ( - 5, - 2) and ( 4,-1), what is the slope?
Slope is the change in y over the change in x.
Slope = (-1 - -2) / (4 - -5)
Slope = 1/9
if f(x)=1/x+2 what is f(3+h)?
If x is the only thing in the denominator, then,
[tex]f(x) = \frac{1}{x}+2\\\\f(3+h) = \frac{1}{3+h}+2\\\\f(3+h) = \frac{1}{3+h}+2\left(\frac{3+h}{3+h}\right)\\\\f(3+h) = \frac{1+2(3+h)}{3+h}\\\\f(3+h) = \frac{1+6+2h}{3+h}\\\\f(3+h) = \frac{7+2h}{3+h}\\\\[/tex]
We replace every copy of x with 3+h, as shown in the second step. Afterwards, we can optionally simplify to form one big fraction.
---------------------------------------------------------------------------
Or if the "x+2" is in the denominator, then we have these steps:
[tex]f(x) = \frac{1}{x+2}\\\\f(3+h) = \frac{1}{3+h+2}\\\\f(3+h) = \frac{1}{h+5}\\\\[/tex]
find the slope and y interceptof y=10x -1/3
with steps ( quick )
Answer:
slope = 10 , y- intercept = - [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 10x - [tex]\frac{1}{3}[/tex] ← is in slope- intercept form
with slope m = 10 and y- intercept c = - [tex]\frac{1}{3}[/tex]
-2(x-2) - 4x = 3 (x + 1) - 9x
Answer:
No solution :(
Step-by-step explanation:
-2(x-2)-4x=3(x+1)-9x love these problems.
-2x+4-4x=3x+3-9x<-- I first multiplied the number outside of the parentheses to the numbers inside. Keep in mind that when a negative time a negative, it equals a positive, in the case of -2*-2.
-6x+4=-6x+3<-- I then combined like terms.
Right away I see that -6 and -6 would cancel out if i just added it to the other side. Thus this equation has no solution.. sorry.

Solve for X and find M Find m
Step-by-step explanation:
3x-28=2x-9
3x-2x=28-9
x=19°
For angle FGH = 2x-9° = 38°-9° = 29°.
For angle HGI = 3x-28° = 57°-28° = 29°.
For angle FGI = 29°+29° = 58°.
