Mia has three bags of marbles. The number of marbles in each bag is 10. How many marbles she has in total?
In this above problem, we are combining three equal groups of marbles where each group has 10 marbles, therefore:
Total number of marbles are = 3 × 10 = 30 marbles
I can't see all ur work that u showed so far
If we call the number x, we can write an equation to solve:
6(x - 4) = 12
6 × x = 6x
6 × -4 = -24
So you get 6x - 24 = 12
6x - 24 = 12
+ 24
6x = 12
÷ 6
x = 2
And your final answer is 2, I hope this helps!
Answer:
x = -1 
Step-by-step explanation:
f(
) = 120, therefore we can create this equation:
120 = 150 ÷ (
- z)
cross-multiply to get: 24 - 120z = 150
-120z = 126
z = -1
