Answer:
x = 40
Step-by-step explanation:
1/2x - 18 = 2
1/2x = 2 + 18
1/2x = 20
x = 20 / 1/2
x = 20 * 2/1
x = 40
Answer:
4:18 and 6:27
Step-by-step explanation:
Answer:
x=4
Step-by-step explanation:
|-4 + 5x|=16
First, combine like terms and use the properties of equality to get all variables on one side of the equation and the numbers on the other.
|5x - 4| = 16
Apply absolute value
5x - 4 = 16
5x - 4 = -16
Add 4 to both sides
5x = 20
5x = -12
Divide both sides by 5
x = 4

Answer:
Step-by-step explanation:
<u>This is the option A</u>
AA
- If two triangles have two of their angles equal, the triangles are similar.
SAS
- If two triangles have two pairs of sides in the same ratio and the included angles are also equal, then the triangles are similar.
SSS
- If two triangles have three pairs of sides in the same ratio, then the triangles are similar.
<u>Other elements mentioned:</u>
- HL- this is a congruence but not similarity
- ASA- same as above
- AAS - neither similarity nor congruence rule
Set up an equation as following: 8.2 * 3.5 = 3.2 * x and solve for x.
8.2 * 3.5 = 28.7
28.7 = 3.2x
*Divide by 3.2 to isolate x*
x = 8.968 and rounded to nearest tenth -> x = 9
