Answer:
x=-1
Step-by-step explanation:
y=4x+10
y=3x+9
-----------
4x+10=3x+9
4x-3x=9-10
x=-1
Answer:
Step-by-step explanation:
By collecting the like terms , we have:
5q - 3q = - 8 - 4 - 2p
2q = -12 - 2p
divide each term by 2 , we have
q = -6 - p
Answer:
70° and 20°
Step-by-step explanation:
let x be the measure of one angle then x + 50 is the measure of the other angle, thus
x + 50 + x = 90
2x + 50 = 90 ( subtract 50 from both sides )
2x = 40 ( divide both sides by 2 )
x = 20
The smallest angle is 20° and the other angle is 20 + 50 = 70°
