Answer:
100
Step-by-step explanation:
100% of a number + 30% of a number is 130% of a number.
This means 130 = 1.3x.
Now we simplify:
130=1.3x
/1.3 /1.3
100=x
x=100
Therefore, the number is 100.
Answer:
x = 40
Step-by-step explanation:
The three angles in a triangle add to 180 degrees
x + 30 + (3x-10) = 180
Combine like terms
4x +20 = 180
Subtract 20 from each side
4x+20-20 = 180-20
4x= 160
Divide each side by 4
4x/4 =160/4
x = 40
Answer:
1 Cups (US) = 0.24992635042 Quarts
either divide or multiply by 0.24992635042
52* 0.24992635042 = 13
13 / 0.24992635042 = 52
