Given:
c = cost
p = people
Spent $300
Formula: c=5p+215
Solving for how many people (p)
C=5P+215
(300)=5P+215 (Subtract 215 on both sides)
85=5P (Divide by 5 on both sides)
17=P
The answer is 17. 17 people can afford to host a birthday party.
Michelle’s method WILL work because we have to add an extra 18% to the already total (100) michaels way would work if the tip was apart of the bill, but it is extra . Hence, Michelle’s method being correct
Answer:
Below in BOLD.
Step-by-step explanation:
1. x^2 = 3^2 + 6^2
x^2 = 9 + 36 = 45
x = √45
x = 3√5.
2. 15^2 = x^2 + 12^2
x^2 = 15^2 - 12^2 = 225 - 144 = 81
x = 9.
9, 10 and 15 are Pythagorean triplets.
3. x^2 = 10^2 - 6^2 = 64
x = 8.
6, 8 and 10 are Pythagorean triplets.
Question five
D is correct
10x-35
Question six
These are true
4(4y+7)
2(8y+14)
8(2y+4) - 4
2y+7(2y+4)
good luck
