Answer:
Heather sent 28, Pablo sent 19, and Shen sent 76.
Step-by-step explanation:
This will be your equation
123 = H (Heather) + P (Pablo) + S (Shen)
This is the extra stuff
P + 9 = H
4P = S
Substitute so there is only P then use that to solve for the rest
123 = P + 9 + P + 4P
Then solve
123 = 6P + 9
123 - 9 = 6P + 9 - 9
114 = 6P
19 = P
Then substitute for the extra equations
19 (P) + 9 = 28 (H)
19 (P) * 4 = 76
Answer:
Step-by-step explanation:
-5f=-3(8-f)
Opening bracket
-5f = - 24 + 3f
Collecting like terms
-5f - 3f = -24
-8f = -24
Dividing by -8
f = -24/-8
f = 3
Answer:
11610
Step-by-step explanation:
First you do the top rectangle which the area for that is 144 which is 4 times 4 times 3 times 3.
Then you do the middle rectangle which the area is 441 which is 7 times 7 times 3 times 3.
Then you do the last rectangle which the area is 11025 which is 15 times 15 times 7 times 7.
Then lastly you add all three areas which is 144+441+11025=11610. So therefore, the answer is 11610.
