Amirah is 4 years older than Priya and Shirley is
jenyasd209 [6]

Answer:

Priyah = 15

Amirah = 19

Shirley = 13

Step-by-step explanation:

Let A represents Amirah, P Priyah and S, Shirley.

So, we have:

A = 4 + P --- 4 years older

S = P - 2 --- 2 years younger

A + P + S = 47

Required

Find their ages

Substitute 4 + P for A and P - 2 for S in A + P + S = 47

4 + P + P + P - 2 = 47

4 + 3P - 2 = 47

Collect Like Terms

3P = 47 - 4+ 2

3P = 45

Divide both sides by 3

P = \frac{45}{3}

P = 15

Substitute 15 for P in A = 4 + P and S = P - 2

A = 4 + 15

A = 19

S = 15 - 2

S = 13

Gwar [14]
Here, You need to substitute the value of x, and y, in the equation then check if L.H.S is equal to R.H.S or not. If they are equal then, ordered pair was correct, otherwise they are not applicable.

75) Here, oly option D can fit i the equation, we can check:
 3(-5) -2(-1) = -15+2 = -13 = R.H.S
So, the pairs are valid.

76) Here, only option D is your answer, 
4(2) - 4 = 8 - 4 = R.H.S

Do the same thing in every equation!

Hope this helps!
