Answer:

B and D

Step-by-step explanation:

Equations with the same x- term on both sides will have no solution

4x - 13 = 5(x + 4) = 5x + 20

4x ≠ 5x

This equation has a solution

5(3 + 2x) = 10x + 4

15 + 10x = 10x + 4

10x on both sides ⇒ no solution

2(3 - 5x) = 8(x + 1)

6 - 10x = 8x + 8

- 10x ≠ 8x

This equation has a solution

9x - 6 = 3(3x - 2) = 9x - 6

9x on both sides ⇒ no solution

A prize was awarded to 24 women and 1130 men. a. What fraction of the prize winners were women? b. What fraction were men?

Brums [2.3K]

a) The fraction of women is $\frac{12}{577}$

b) The fraction of men is $\frac{565}{577}$

Step-by-step explanation:

In this part of the problem, we are asked to find what fraction of the prize winners are women.

We have:

$w=24$ (number of prizes awarded to women)

$m=1130$ (number of prizes awarded to men)

First of all, we calculate the total number of prizes awarded:

$p=w+m=24+1130=1154$

Now we find the fraction of prize winners who were women, which is given by:

$p(w) = \frac{w}{p}=\frac{24}{1154}$

And we can simplify by dividing both numerators and denominators by 2,

$p(w)=\frac{24}{1154}=\frac{12}{577}$

The total number of prizes awarded is

$p=1154$

The number of prizes assigned to men is

$m=1130$

Therefore, the fraction of prize winners who were men is

$p(m)=\frac{m}{p}=\frac{1130}{1154}=\frac{565}{577}$

where we simplified the fraction by dividing both the numerator and the denominator by 2.

Plss help due today !!!!

Sladkaya [172]

Answer:

$30

Step-by-step explanation:

She paid $24.72 for the 2 packages of chicken because $12.36×2=$24.72.

She paid $0.99 for the broccoli because $1.98×1/2=$0.99.

She paid $3.49 for the milk because one gallon of milk costs $3.49.

$24.72+$0.99+$3.49=$29.20.

$29.20+$0.80=$30.00.

She used $30.00 to pay for the items.

Write an equation of the line that passes through the given points.<br><br> (−5,−2),(−5,0)

agasfer [191]

Answer:

y=-2

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(0-(-2))/(-5-(-5))

m=(0+2)/(-5+5)

m=2/0

y-(-2)=0

y+2=0

y=0-2

y=-2
