Answer:
x = 3
Step-by-step explanation:
First distribute
2x + 4x - 4 = 2 + 4x
combine like terms
6x - 4 = 2 + 4x
continue
2x - 4 = 2
add 4 to both sides
2x = 6
divide both sides by 2
x = 3
Answer:
Lisa earned $247.50 for working 33 hours.
Step-by-step explanation:
WAY 1: proportional reasoning
7.50 x
------ = ----
1 h 33h
33 / 1 = 33
7.50 x 33 = 247.5
WAY 2: unit rate reasoning
7.50 per hour so x value of money for 33 h
7.50 x 33 = 247.5
5.62 would be 5 62/100 then you can simplify the fraction down
62/100 - 31/50
5 31/50
Hope I helped :)
Answer:
By definition of congruence
Step-by-step explanation:
Triangle ABC is congruent to triangle DBE
Blank 1: 3
Blank 2: 27
Blank 3: 21
you have to distribute the three to everything inside the parenthesis, and because it's directly in front of the parenthesis it's being multiplied.
3(x - 9) = 3x - 27
Now you need to isolate the y, in this e ample you need to add 6 to both sides
the final equation should be:
y = 3x - 21
