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:
equation of line:
y = mx + b....equation(1)
slope = m = -1/4
y-intercept = b =?
put point(12,5) and slope (-1/4) in equation(1)
5 = (-1/4)(12) + b
5 = -12/4 +b
5 = -3 + b
5 + 3 = b
b = 8
putting values of b and m in equation(1)
y = (-1/4)x + 8
Step-by-step explanation:
If they have the same numerator and denominator for example 4/4 and 2/2 are equivalent because you could divide 4/4 to get 2/2 or multiply 2/2 to get 4/4

Answer:
E, 297.1
Step-by-step explanation:
First, find the area of the triangle using the formula a= (bh) / 2
Base x height would be 16 x 12, which is 192
192 / 2 is 96 sq meters
Then, find the area of the circle using the formula a= Pi (r^2)
If the diameter is 16, the radius would be 8 because you divide by 2
8^2 is 64, 64 times Pi is approximately 201.1
Finally, add the areas together, 96 + 201.1 is 297.1 or E
