Answer: It is D
Step-by-step explanation:
3ft in a yd
14ft to 6ft to 7ft to 3ft
-3z + 7 = -7 - 10z
Add 10z to both sides
7z + 7 = -7
Subtract 7 from both sides
7z = -14
Divide by 7
Z = -2
Answer:
Step-by-step explanation:
(2 - 3)/(4 - 0) = -1/4
y - 2 = -1/4(x - 4)
y - 2 = -1/4x + 1
y = -1/4x + 3
Since the intersection is - by definition - common to both sets, we can work out the number of people that use only the fitness suite or the swimming pool.
We know that 57 people use the fitness suite, but 36 of those are already counted in the intersection. So, 57-36=21 people use only the fitness suite.
The same goes for the swimming pool: 49-36=13 people use only the swimming pool.
So, we have:
- 21 people using fitness suite only
- 13 people using swimmng pool only
- 36 people using both
This sums to 21+13+36=70 people. We deduce that 30 people don't use any of the features.
Answer:
Mark: 15 ounces
Lili: 5 ounces
Step-by-step explanation:
Mark drank 5/8 of a 24 ounce can of juice.
The ounces Mark drank
![=\frac{5}{8}\times 24](https://tex.z-dn.net/?f=%3D%5Cfrac%7B5%7D%7B8%7D%5Ctimes%2024)
![=5\times 3](https://tex.z-dn.net/?f=%3D5%5Ctimes%203)
Mark drank 15 ounces.
Lili drank 1/3 as much juice as Mark did.
The ounce Lili drank
![=\frac{1}{3}\times 15=5](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B3%7D%5Ctimes%2015%3D5)
Lili drank 5 ounces.
