1/5 (a + 10) = -3
Use distributive property
1/5a + 2 = -3
Subtract 2 from both sides
1/5a = -5
Divide by 1/5 on both sides
a = 1/25
The greatest common factor of 99 and 66 is 33 because that is the highest number that BOTH numbers can be multiplied by
33 x 3 = 99
33 x 2 = 66
x/100 = 35/185
Cross multiply
185x = 3500
Divide on both sides
x = 18.9189189189
If you want to round:
x = 18.92% or 19% or 18.9%
402 miles squared is 20.0499376558
3ax = 1/5
divide by 3a on both sides
x = 1/15a
1 googol is 1.0 × 10100
10.3 , 10.9 , 10.6 , 10.1 , 10.5
Add them all together
52.4
Now divide by the number of numbers (5)
10.48
1/3 ÷ 9
Use the recipricle and multiply
1/3 x 9/1
Multiply
9/3
Simplify
3
9 + 10 = 19
2 - 2 = 4 :)
