Answer:
20 + 35x
Step-by-step explanation:
We have the expression 5(4 + 7x) and are asked to distrbute it.
When distributing, it's very simple, all you have to do is multiply the number outside the parenthesis with the numbers inside the parenthesis.
Therefore :
(5(4) + 5(7x))
20 + 35x
2x -20 -1 =0
2x -21=0
2x=21
x= 10.5
Answer:
20
Step-by-step explanation:
Divide 4 by 1/5 in decimal form, 1/5 in decimal form is 0.20. You can get the decimal form by dividing 1 by 5.
So 4/0.20 = 20.
(180-x)-2(90-x)= 53
Remember that complimentary angles add to 90 and supplementary angles add to 180.
180-x-180+2x=53
x=53
Final answer: The angle is 53 degrees.
