Answer:
109
Step-by-step explanation:
Formula
<ZHG + <IHZ = <IHG
Givens
<ZHF = 11x - 1
<IHZ = 24
<IHG = 12x + 13
Solution
11x - 1 + 24 = 12x + 13 Combine terms on the left
11x + 23 = 12x + 13 Subtract 13 from both sides
<u> - 13 - 13 </u>
11x + 10 = 12x Subtract 11x from both sides
<u>-11x -11x</u>
10 = x
Answer
11x - 1 = 11*10 - 1 = 110 - 1 = 109
Answer: First we will substitute the numbers given for the variables.
Then we will use order of operations to simplify.
7x + 5z(x - z) ÷ 9y would be equal to
7(5) + 5(8) * (5 - 8) ÷ 9(23)
Simplify:
35 + 40(-3) ÷ 207
Use order of operations to multiply 40 and -3; the equation now looks like:
35 + (-120) ÷ 207
Use order of operations to divide -120 and 207; the equation now looks like:
35 + (-0.6)
Add 35 and -0.6:
34.4
The solution to this equation is 34.4.
60 divided by 5 is 12, so one pizza is 12$. then do 9 times 12 and you'll get 108. so 9 pizzas cost 108$.
