5. x*(76-39)
6. 75+x
7. 45-3x
8. 2x+15
9. 3x-25
10. x*(x+88)
Step-by-step explanation:
The answer is either x>-7 or x<-7 I think it is the first one but I haven’t done these in a while so I forget when to switch the signs
Answer:
|5y|+8/x
Step-by-step explanation:
The mathematical expression is |5y|+8/x
ANSWER
x=27
EXPLANATION
The two triangles are similar so the corresponding sides are equal.
Cross multiply to get;
Expand:
65x=39x+702
Group similar terms:
65x-39x=702
Simplify
26x=102
Divide both sides by 26,
x=702/26
x=27
Good evening
Answer:
<h2>measure of Angle 1 = 81°</h2><h2>Measure of angle 2 = 9°</h2>
Step-by-step explanation:
we need to solve this system
x + y = 90 (1)
x = y + 72 (2)
If we substitute x by y+72 into the equation (1) we will get
(y+72) + y = 90 ⇔ 2y + 72 = 90 ⇔ 2y = 90 - 72 = 18 ⇔ y = 9
then x = 90 - 9 = 81
