X=1/2-3y/4
and
x=10/3+2y/3
Answer:
49 different ways
Step-by-step explanation:
If there are seven roads that lead to the top, you have seven possible choices to go to the top of the hill.
Then, to come back to the start, you also have seven possible choices (seven roads), and you can pick any road.
So, if you have seven ways to go up and seven ways to go down, the number of different ways of going to the top and coming back is the product of these numbers of possible choices.
N(total) = N(up) * N(down)
N(total) = 7 * 7
N(total) = 49 different ways
Brainliest pls and tysm!
Hence there is no such natural numbers exist.
Answer:
66 girls
Step-by-step explanation:
Givens:
●120% boys of girls
▪︎1.2 × g
☆when g is the number of girls
●80 boys
▪︎meaning you can set up a proportion
Solving:
g × 1.2 = 80
g=80/1.2
g=66.66
So, since you can't go over percent, the answer is 66.
Checking:
g × 1.2 = 80
66 × 1.2 = 80
80=80✅
Answer:
y/4 + x/12
Step-by-step explanation:
The number of working toys = x
The number of broken toys = y
Bert breaks 1/3 of the working toys, that is:
1/3 * x = x/3
The number of broken toys is now:
y + x/3
Ernie then throws away 1/4 of the broken toys. In terms of x and y, the number of broken toys that Ernie threw away is:
1/4 *(y + x/3)
= y/4 + x/12
