Answer:
3/5 * 4/7 = 12/35
you can find the answer by multiplying the numerator by the other numerator and the denominator by the other denominator
Let b be the initial amount of books. Steve sells half of his books, so the number of Steve's books become
Then, he buys 6 more, so the number increases by 6:
This number is now 14, so you have
Subtract 6 from both sides:
Multiply both sides by 2:

Answer:
Step-by-step explanation:
We assume the given ratios are proportional. I find it easiest to write the proportion with the unknown in the numerator.
a) dollars/ounces = x/17 = 7/20
Multiply by the inverse of the coefficient of x to solve.
x = 17(7/20) = 5.95 . . . dollars
__
b) bushels/acres = x/9.6 = 225/3
x = 9.6(225/3) = 720 . . . bushels
Answer:
x = 18°
m∠A = 110°
Step-by-step explanation:
Hello!
Angle A and Angle B are supplementary. Supplementary means they add up to 180°.
Step 1: Solve for x
We can add the two angles together and make it equal to 180° because they are supplementary.
- Angle A + Angle B = 180°
- 5x + 20° + 9x - 92° = 180°
- 14x - 72° = 180°
- 14x = 252°
- x = 18°
x = 18°
Step 2: Solve for Angle A
Now that we know the value of x, we can plug it in for the equation of Angle A and solve for the measure of Angle A
- Angle A = 5x + 20°
- Angle A = 5(18°) + 20°
- Angle A = 90° + 20°
- Angle A = 110°
Angle A = 110°
