The answer is 8.2×10^5 . All you have to do is move the decimal place over till there is only one number after the decimal.
Answer:
One block - 15
Two blocks - 30
Three blocks - 45
Four blocks - 60
Five blocks - 75
Equation: 25 + 5x = 100
Step-by-step explanation:
This is a pretty simple problem. The scale is balanced and from what we know, the 100 and 25 are on different sides. If we want the scale to be balanced, then we have to solve the equation:
25 + 5x = 100.
(We have the 5x because we have 5 blocks that are marked as x)
subtract 25 from both sides
25-25 + 5x = 100-25
5x = 75
the following step is to divide both sides by 5.
5x/5 = 75/5
x = 15
Now that the equation is solved, we know that ONE blocked marked as X equals 15-g.
(All five of them equal 75-g)
6x + 5x + (x + 16) + (3x - 1) = 360
11x + x + 16 + 3x - 1
15x + 15 = 360
15x = 345
x = 23
6(23) = 138
((23) + 16) = 39
(3(23) - 1) =68
5(23) = 115
138 + 39 + 68 + 115 = 360
Answer:
10=z or z=10
Step-by-step explanation:
1) Add four to both sides
2) You should get 10=z
