3 times 10 is 30, 7 times 10 is 70. There are 30 girls and 70 boys.
Answer:
- 12x +9y ≥ 510
- y ≤ 2x
- y ≥ 25
Step-by-step explanation:
Phoebe earns 12x for her yard weeding, and Richie earns 9y for his dog walking. They want the sum of these earnings to be at least 510, so the first constraint inequality is ...
12x +9y ≥ 510
__
Richie plans to walk no more than 2x dogs, since y is the number of dogs he walks, the second constraint is ...
y ≤ 2x
__
Richie will walk at least 25 dogs, so ...
y ≥ 25
The answer is c.
Since a^2+b^2=c^2, b^2=c^2-a^2 thus,
16=4-b^2= srt. of 12
Because if you put a two on one side and put the inverted version of 2, then join them on their lines, it forms a fish. I have more of those types of questions:
1+1=田
2+2=fish
3+3=8
4+4=↑
5+5=cylinder
6+6=headset
7+7=▼
8+8=butterfly
9+9=cup
