If both are complementary then their sum will be 90°

\\ \sf\longmapsto m

\\ \sf\longmapsto 2x-10+x-2=90

\\ \sf\longmapsto 2x+x-10-2=90

\\ \sf\longmapsto 3x-12=90

\\ \sf\longmapsto 3x=90+12

\\ \sf\longmapsto 3x=102

\\ \sf\longmapsto x=\dfrac{102}{3}

\\ \sf\longmapsto x=34

Now

\\ \sf\longmapsto

Hi there.

Y = 2x + 3
Solve for y when x = 3
The first thing we need to do is replace x by the 3 in the equation.
Y = 2(3) + 3
Y = 6 + 3
Y = 9
Thus, your answer is : C

Solve the equation: 5x + 7= 7x +23
olga nikolaevna [1]

Answer:

x = -8

Step-by-step explanation:

1)  5x + 7= 7x +23

Move the terms

2)  5x + 7 -7x = 23

Collect like terms

3)  5x -7x = 23 - 7

Calculate

4)  -2x = 16

Divide both sides by <em>-2</em>

5)  x = -8

kondor19780726 [428]
Let Ricky = x; so equation: x + (x+283) = 2675 ; Re-arrange so x = Ricky = 1196 hits with Pedro 1196 + 283 = 1479.

Geometry circles question
CaHeK987 [17]
Answer: 14 

----------------------------------------------

Explanation:

Using the intersecting chord theorem, we can say,

AP*PB = CP*PD
(x+2)*6 = 7*x
6x+12 = 7x
6x+12-6x = 7x-6x
12 = x
x = 12

If x = 12, then,
AP = x+2
AP = 12+2
AP = 14
