3 - what = 11 please help with this one

1 answer:

3 0

So we can set up a simple equation for this, where the word “what” is a variable, x. This equation is 3 - x=11. Then we subtract 3 from both sides, giving us -x=8. We can divide both sides by -1, giving us x=-8. The answer would be -8. Hope this helped.

Which choice gives the center and radius of the circle represented by the equation?

shutvik [7]

$(x-h)^2+(y-k)^2=r^2$ is the equation of a circle centered at $(h,k)$ with radius $r$ .

Here $h=7$ , $k=-3$ , and $r^2=25\implies r=5$ . So the answer is (C)

If you take a number, times by 8 then add 6. You get the same as if you took the number multiply it by 3 then subtract 7. What i

Gennadij [26K]

Answer:

x = -13/5

Step-by-step explanation:

let x be the number

8x + 6 = 3x - 7

move variables to left and numbers to right

8x - 3x = - 7 -6

5x = -13

x = -13/5

A class of 33 students elected a class treasurer. There were 11 votes for Candidate A and 15 votes for Candidate B. The remainin

vovangra [49]

To start out, notice that you want the percent of voters that chose candidate A, not the percent of the class that chose candidate A.

Your fraction should be "number that chose candidate A" out of "number of voters," which is the same thing as saying:
"number that chose candidate A" divided by "number of voters"

1) The numerator of the fraction should be the number of votes for candidate A, which is 11.

2) The denominator of the fraction should be the number of voters. You're told that "t<span>here were 11 votes for Candidate A and 15 votes for Candidate B," so there are:
</span> $11 + 15 \: total \: votes$

3) Finally put parts 1 and 2 together into a fraction and multiply by 100 to get your percent. That is your final answer:
$\frac{11}{11+15} \times 100$

----

Answer: Top right choice, $\frac{11}{11+15} \times 100$

Lee wants to collect 22 of a certain type of action figure. He had 11 of the figures, then got 3 more for his birthday. What dec

Shalnov [3]

To solve this problem, we must first find the fraction of action figures that Lee has gotten so far. To do this, we will represent the number of action figures that Lee currently has in the numerator divided by the denominator, the total number of action figures that Lee is attempting to collect.

First, we must recognize that Lee currently has 11 action figures plus the 3 that he got for his birthday. To find the total number of action figures that Lee has, we must add together these two parts.

11+3 = 14

Therefore, Lee has 14 action figures (this will become the numerator of the fraction). The denominator of the fraction is the total number of action figures, which we are given is 22.

Thus, our fraction is 14/22.

To convert this into a decimal, we can simply divide the numerator of the fraction by the denominator of the fraction, which gives us:

14/22 = 0.636363636

Therefore, your answer is approximately 0.636.

Hope this helps!
