AC = AB + BC
= (x + 2) + (7x - 3)
= (x + 7x) + (2 - 3)
= 8x - 1
AC = 8x - 1
QR = PR - PR
= (13y + 25) - (8y + 5)
= 13y + 25 - 8y - 5
= 13y - 8y + 25 - 5
= 5y + 20
QR = 5y + 20
Hence, simplified expression for AC = 8x - 1
Simplifie expression for QR = 5y + 20
2, because since 65 is being multiplied by 32, 32 can be split into 30 and 2
Answer:
the answer is D. 40
Step-by-step explanation:
Answer:
She needs at least 73%
Step-by-step explanation:
1. add all of the numbers up and d the quantity to find
93+67+82+71+94/5
=407/5
=81.
2. try diffrent numbers
407+73/6
=480/6
=80
She needs at least 73%
Your answer would be choice d , hope this helps!
