Jacob painted 3/4 of a wall his little brother painted 1/2 of what was left how much of the wall is still unpainted

Leni [432]

Lets do this step by step:

1 wall = 1 whole or $\frac{1}{1}$
Jacob painted $\frac{3}{4}$ of the wall
$\frac{1}{1} - \frac{3}{4} = \frac{1}{4}$ (because $\frac{3}{4}$ is a quarter of 1 whole)
His little brother painted $\frac{1}{2}$ of the wall
$\frac{1}{4}-\frac{1}{2} =$
Find the common denominator which is 4:
1/4 × 1 = 1/4 and 1/2 × 2 = 2/4
$= \frac{1}{2}$ (because a half of 1/4 is 1/2)

Therefore your answer is "1/2."

Hope this helps!

Help please i am stuck

BaLLatris [955]

Answer:

x = 25

Angle B = 65 degrees

Angle C = 50 degrees

Step-by-step explanation:

All triangles will add up to 180 degrees.

65 + 3x - 10 + 2x = 180

Combine like terms

55 + 5x = 180

Subtract both sides by 55

5x = 125

Divide both sides by 5

x = 25

Plug in the value for x in angle B:

3(25) - 10

75 - 10

65

Do the same for angle C:

2(25)

50

Check your work:

65 + 65 + 50 = 180

180 = 180

Correct
