First you have to find what 30% of ten is, and then add it to the 10. So how do you find 30 % of 10? In math...
"of" means ×
"is" means =
30% of 10 is
30 % × 10 =
change 30% to a decimal by dividing by 100 ( move the decimal to the left 2 places)
.30 × 10 = 3
So 30% of ten is 3. Now since we are increasing by 30%, we have to add it to the original value, 10.
3 + 10 = 13
So 10 millimeters increased by 30% is
13 millimeters
Answer:
y = 8/5x
Step-by-step explanation:
I'm assuming that they're asking for the equation in point-slope form.
The formula is y=mx+b where:
m = slope
b = y intercept
However, the y intercept is just (0,0) so b = 0
To find the slope we already have 2 given points: (0,0) and (5,8)
To find slope you do rise/run and you get 8/5
Substitute the slope & y intercept in the formula:
y = 8/5x
Let me know if I'm wrong!!
Since it's a one-variable equation, it has only one solution:
25 - 4x = 15 - 3x + 10 - x
25 - 4x + x = 15 - 3x + 10
25 - 3x = 15 - 3x + 10
- 3x = 15 - 3x + 10 - 25
- 3x = 15 - 3x - 15
- 3x + 3x = 15 - 15
0 = 15 - 15
0 = 0
