This is the answer with step by step explanation
Answer:
x = 20
Step-by-step explanation:
The two angles are complementary angles, which means they add to 90 degrees
2x+7 + 43 = 90
Combine like terms
2x+50 = 90
Subtract 50 from each side
2x+50-50 = 90-50
2x = 40
Divide each side by 2
2x/2 = 40/2
x = 20
Answer:
B) 4
Step-by-step explanation:
(2*4)+(2*1)=10 So, 10/2=2 but both sides 4
Answer:
6:22,10:110,9:33
Step-by-step explanation:
all the answers are factors of 3 and 11
One way of doing this is to write the equation of ratios (15 screwdrivers / 45 screwdrivers) = ($300 / x). Solve this equation for x. To do this, you might try multiplying both sides of this equation by x to eliminate fractions.
Another way is to obtain the unit cost of each screwdriver and then multiply the result by 45 screwdrivers.
