2. What does y equal? *<br> y+3/4 = 6
kakasveta [241]

Answer:

3rd option

Step-by-step explanation:

Given

y + \frac{3}{4} = 6 ( multiply through by 4 to clear the fraction

4y + 3 = 24 ( subtract 3 from both sides )

4y = 21 ( divide both sides by 4 )

y = \frac{21}{4} = 5 \frac{1}{4}

Point p is the midpoint of DE. DP =3x + 2 and DE = 10x - 12. What is the length of DP
shepuryov [24]
If P <span>is the midpoint of DE then 
DE = 2(DP)
10x - 12 = 2(3x + 2)
10x - 12 = 6x + 4
10x - 6x = 4 + 12
4x = 16
x = 16/4
x = 4

DP = 3x + 2 = 3 * 4 + 2 = 12 + 2 = 14 units</span>

Solve for x. (RIGHT ANSWER WILL GET BRAINLIEST)
puteri [66]

Answer:

67

Step-by-step explanation:

The angle with x in it is a vertical angle to the other one labeled & the right angle put together.

Therefore:

48 + 90 = 2x + 4

Solve for x:

138 = 2x + 4

138 - 4 = 2x + (4-4)

134 = 2x

134/2 = 2x/2

X = 67

Hope this helps! Have a great day!
