Answer:
p = -3
Step-by-step explanation:
−0.63p − 5.04 + 3.57 = 7.05 + 2.21p
−0.63p − 1.47 = 7.05 + 2.21p (add 0.63p to both sides)
− 1.47 = 7.05 + 2.21p + 0.63p
− 1.47 = 7.05 + 2.84p (subtract 7.05 from both sides)
− 1.47 - 7.05 = 2.84p
-8.52 = 2.84p (rearrange)
2.84p = -8.52 (divide both sides by 2.84)
p = -8.52 / 2.84
p = -3
5. since .6 is greater than 5, we round up.
64/100
= (64/4) / (100/4)
= 16/25
The final answer is 16/25~
SUM: x + y = 288
DIFFERENCE: + <u>x - y = 48 </u>
2x = 336
x = 168
SUM: x + y = 288 → (168) + y = 288 → y = 120
Answer: 120, 168
