Answer:
$24.38
Step-by-step explanation:
f(h) = 3.75h + 7.50
h = 4.5
f(4.5) = 3.75(4.5) + 7.50
f(4.5) = 24.375
Answer: $24.38
A positive + A positive = A positive (1+2=3)
A negative + A negative = A negative (-1+(-2)=-3)
Adding a negative is like subtracting a positive (1 + (-2) = -1) this is equal to (1 - 2 = -1)
Adding a positive is like subtracting a negative (-1 + 2 = 1)
If Jill has $8.75 and Jack has 3 times that
Jack has $26.25

X - 2y = -29
x - y = -11
first solve for x in the first equation;
x = 2y - 29
now substitute it into the second equation;
x - y = -11
2y - 29 - y = -11
y - 29 = -11
solve for y;
y - 29 = -11
y = -11 + 29
y = 18
solve for x by substituting what y equals;
x = 2y - 29
x = 2(18) - 29
x = 7
so your answer is, (7, 18)
hope this helped!! blessings x
8 ft wide, 12 ft long......so if u want it 2 ft wide, u have a scale factor of 1/4.
that means ur length will be 12 * 1/4 = 12/4 = 3 ft long
A = L * W
A = 3 * 2
A = 6 square ft <==
