Answer:
6750:9000*100 =
(6750*100):9000 =
675000:9000 = 75
Now we have: 6750 is what percent of 9000 = 75
Question: 6750 is what percent of 9000?
Percentage solution with steps:
Step 1: We make the assumption that 9000 is 100% since it is our output value.
Step-by-step explanation:
6750:9000*100 =
(6750*100):9000 =
675000:9000 = 75
Now we have: 6750 is what percent of 9000 = 75
Question: 6750 is what percent of 9000?

Fraid not. This time, you did it left.
The tool to use is "Vertical" angles are equal. (They don't add up to 180 degrees.)
3y + 120 = 5y + 100
(you should fill in the missing steps)
y = 10°
The upper/lower pair of vertical angles are both 150°.
.
2x = 6x - 60
(you should fill in the missing steps)
x = 15°
The left/right pair of vertical angles are both 30°.
It's any two angles NEXT TO each other that add up to 180°.
Notice here that (150° + 30°) = 180° .
Answer:
a) 3x-5=16
b) 30cm
Step-by-step explanation:
a) 5(x-1)=2(x+8)
5x-5=2x+16
5x-2x-5=16
3x-5=16
b) solving the equation gives x=7
put x=7 into first line, 5(7-1)=30cm
to check we can place it into second one as well
2(7+8)=30cm
