Answer:
-4
Step-by-step explanation:
Two legs of the triangle are congruent as shown by the tick marks. This means that this is an isosceles triangle; in an isosceles triangle, the two base angles are also congruent. Which means <A and <B are congruent.
So to solve for x, set 28 and 10x+68 equal to each other.
28=10x+68
First, subtract 68 from both sides
-40=10x
Then, divide both sides by 10
-4=x
If you want to check your answer plug -4 back into the original equation.
28=10(-4)+68
28=-40+68
28=28, which is true, therefore -4 is correct.
Answer:
(-15)-(-3) = -12
(1-7)+(+5) = -1
(+5) x ( +6 ) = 30x
(+18 ) + ( +6) 24
(9)+( 8 ) = 17
(+10)-(+1) = 9
( +4 ) x ( 3 ) = 12x
( 12 ) + ( +4 ) = 16
(+6) + (6) 12
(+11)-(7) = 4
(-8) x ( +2 ) = -16x
(+15) + ( 3 ) = 18
(*12 ) + ( 4) = 4
(8) - ( +2) = 6
(-7) x ( -5 ) = 35x
