Answer:
W=28
Step-by-step explanation:
(W/4)-4=3
(W/4)=7
W=28
8 - 4 = 7 - 3 because it has a equal sign in the middle meaning that you have to find an equation that’s equal to it. So thats why the missing number is 3
She will need 30 apples more and 200 apples in total.
Answer:
The equations are:
10x + 9y = 122
x + y = 13
Step-by-step explanation:
Given Jose makes 10$ per hour washing cars and 9$ per hour walking dogs.
Also, it is given that he had worked for 13 hours total making 122$.
Let us assume the number of hours he spent on washing cars = 'x'.
Let us assume the number of hours he spent on walking dogs = 'y'.
Since, the total number of hours is 13, we can write:
x + y = 13 . . . eqn(1)
And since he has made 122$ in total, we will have:
10x + 9y = 122 . . .eqn(2)
'10x' represents the total money earned by washing cars and '9y' represents the total hours spent on walking dogs.
Hence, Eqn (1) and Eqn(2) is the answer.
Solving them will give: x = 5 and b = 8.
Answer:
24
Step-by-step explanation:
the height of a triangle is A=(b·h)÷2
We know the area and base so replace: 72=(6×h)÷2
Solve:
72=(6×h)÷2
·2 ·2
144=6h
÷6 ÷6
h=24
24 yards
