An "equation" has a left side, a right side and an equals sign separating the sides. An "expression," by contrast, doesn't have any "sides" and is simply what the name suggests: An algebraic "expression<span>."</span>
-3 - (-10) - 8
The double negative sign changes the sign to a positive sign.
-3 + 10 - 8
Solve -3 + 10 first.
-3 + 10 = 7
Now solve 7 - 8.
7 - 8 = -1
-1 is your answer.
Answer:
x = 38°
Step-by-step explanation:
in the given question,
the two angles are complementary, because sum of their measures = 90°
so,
=》52° + x = 90°
=》x = 90° - 52°
=》x = 38°
Answer:
Step-by-step explanation:
Given two similar triangles.
Corresponding parts of similar figures have same ratio.
<u>Use ratios to find the value of x:</u>
- (4x - 5)/(x + 7) = 35/12.5
- (4x - 5)/(x + 7) = 14/5
- 5(4x - 5) = 14(x + 7)
- 20x - 25 = 14x + 98
- 20x - 14x = 98 + 25
- 6x = 123
- x = 123/6
- x = 20.5
