28.3 / 9 = 3.14444444......
3.14 round to 3
72 ÷ 6 = 12 and 12 × 36 = 432 and 72 × 36 = 2,592 and 2,592 ÷ 6 = 432
Answer:
y = 60 when x = 12
Step-by-step explanation:
Direct variation is
y = kx
15 = k3
Divide by 3
15/3 = k
5 =k
y = 5x
Let x = 12
y = 5*12
y = 60
Answer:
The value of x is 3
Step-by-step explanation:
First, you must expand everything:
2(2x+1) - 3(x-1) = 8
2(2x)+2(1) - 3(x)+3(1) = 8
4x + 2 - 3x + 3 = 8
x + 5 = 8
Then, move all the unknown value to one side:
x = 8 - 5
= 3
Answer:
Explanation:
Given:
Each student receives the same number of toothpicks (t) for a project
To find:
te equation that can be used to find the total number of toothpicks, N, given out by the teacher
let each toothpick student received = t
let the total number of students = s
total number of toothpicks = N
Total number of toothpicks = each toothpick student received × total number of students
