For what value of x is angle 1 complementary to angle 2, if m angle 1=5x+4 and m angle 2=7x+2?

belka [17]

Two Angles are Complementary when they add up to 90 degrees (a Right Angle). They don't have to be next to each other, just so long as the total is 90 degrees.

So (5x + 4) + ( 7x + 2) = 90

12x + 6 = 90

12x = 90 – 6

12x = 84

X = 7

sam is cooking cookies the recipe calls for 3 4/5 cuos of flour. she accidentally puts in 5 1/4 cups how many extra cups did she

nevsk [136]

First, we have to get the fractions to common denominators.

4/5 = 16/20
1/4 = 5/20

5 5/20 - 3 16/20 = 1 9/20

She put 1 9/20 extra cups in.

Ella grew 3 over 4 of an inch last year. Ben grew 2 over 3 of an inch last year. How much more did Ella grow than Ben last year?

IrinaK [193]

Answer:

Ella grew $\frac{1}{12}$ of an inch more

Step-by-step explanation:

For this problem, you want to subtract Ben's growth from Ella's.

This expression would be $\frac{3}{4}$ - $\frac{2}{3}$ .

To work these out, they must have the same denominator (which should be the lowest common multiple or LCM).

In this case, the LCM is 12, so you want to multiply each side so the denominator is 12. This means the first fraction should be multiplied by $\frac{3}{3}$ and the second by $\frac{4}{4}$ .

This makes the expression $\frac{9}{12}$ - $\frac{8}{12}$ , which equals $\frac{1}{12}$ .
