Answer:
x + (x-42.2) = 90
2x - 42.2 = 90
add 42.2 to both sides
2x = 132.2
divide each side by 2
x = 66.1
find the measure of the other angle
66.1 - 42.2 = 23.9
Step-by-step explanation:
Answer:
y=3/2x+8
Step-by-step explanation:
2 divided by 5 = 0.4
2/5 = 0.4
2/5 is equal to 0.4
1. determine the defined range
2. write all numerators above the common denominator
3. remove parenthesis
4. collect like terms
5. multiply both sides by (2x+1) x (2x-1)
6. simplify the product
7. multiply parenthesis by -4
8. cancel equal terms
9. move constant to the right
10. add the numbers
11. divide both sides by 6
ANSWER: x = 11/6
