I really don’t understand what the questions asking? How do I solve this

Eddi Din [679]

Answer:

$17.85

Step-by-step explanation:

Let the dollar amount per shirt be represented by s.

Let the dollar amount per pants be represented by p.

You have the following system:

3s+2p=104.81

2s+1p=61.33

If I multiply the bottom equation by -2, I can set the system up for elimination since the equations are already and the same form and I will have 2p and -2p in the same column there. 2p+(-2p)=0

Multiplying equation 2 by -2:

3s+2p=104.81

-4s-2p=-122.66

-----------------------Add the equations:

-1s =-17.85

Multiply both sides by -1:

s=17.85

So one shirt cost $17.85

Question 1:

5z – 9 = 36

5z = 45

z = $\frac{45}{5}$

z = 9

Hence, the answer is D.

Question 2:

5(2z + 4) = 0

10z + 20 = 0

10z = -20

z = $\frac{-20}{10}$

z = -2

Hence, the answer is A.

Question 3:

4a + 3(a + 1) = 24

4a + 3a + 3 = 24

7a = 21

a = $\frac{21}{7}$

a = 3

Hence, the answer is B.

Question 4:

3(4x + 5) = 12

12x + 15 = 12

12x = 12 - 15

12x = -3

x = $\frac{-3}{12} = - \frac{1}{4}$

Hence, the answer is A.

Question 5:

4x – 8 – 4x = 9

-8 ≠ 9

Hence, the answer is A.

marishachu [46]

Answer:

$(x + 7)^2 + (y + 4)^2 = 4$

Step-by-step explanation:

The equation of a circle with radius r and center (h, k) is:

$(x - h)^2 + (y - k)^2 = r^2$

This circle has center (-7, -4) and radius 2.

The equation is:

$(x + 7)^2 + (y + 4)^2 = 4$

Jenny purchased a prepaid phone card for $30 . long distance calls cost 6 cents a minute using this card. jenny used her card on

yuradex [85]

So if she still has $27.12, then during her call, she used a total of $2.88.

$2.88 = 288 cents.

Therefore 288 divided by 6 = 48

Therefore the answer is 48 minutes.
