So we first group the like terms
3x + 8x + x - 13 + 10 = 72
We now make x the subject
3x + 8x + x = 72 + 13 -10
Evaluate
12x = 75
x = 75/12
x = 6.25

If mBGC = 16x - 4 and mCGD = 2x + 13, find the value of x so that BGD is a right angle​
Lelu [443]

Hi there! :)

Answer:

\huge\boxed{x = 4.5}

m∠BGC = 16x - 4

m∠CGD = 2x + 13

m∠BGC + m∠CGD sums up to 90°, therefore:

(16x - 4) + (2x + 13) = 90

Combine like terms and simplify:

16x + 2x - 4 + 13 = 90

18x - 4 + 13 = 90

18x + 9 = 90

18x = 81

18x/18 = 81/8

x = 4.5

Please help me :/!!!!
Dovator [93]

Answer:

(3, 9)

Step-by-step explanation:

Set 3x and 2x+3 equal to each other forming an equation in x.

3x=2x+3

Solve for x.

x=3

Substitute the given value of x into the equation y=3x.

y=3x3

Solve for y.

y=9

(x, y) = (3, 9)

Hope this helps :)
