Answer:
1st mechanic:20hours
2ndmechanic:15hours
Step-by-step explanation:
1stmechanic:20hours=20x95
=$1900
2nd mechanic:15hours=15x110
=$1650
total=<u>$1900+$1650</u>
=$3550
Answer:
140° and 40°
Step-by-step explanation:
let x be one angle then the other is 
x - 30
Since the angles are a linear pair, theis sum is 180° , then
x + x - 30 = 180, that is
x - 30 = 180 ( add 30 to both sides )
x = 210 ( multiply both sides by 2 to clear the fraction )
3x = 420 ( divide both sides by 3 )
x = 140
and x - 30 = (140) - 30 = 70 - 30 = 40
The 2 angles are 140° and 40°
3 + 126 - 4• 526 - (4x)
3 + 126 -2104 -4x
-4x -1975
Answer:
x=2;y=2
Step-by-step explanation:
2x+y=6..........1
3x-y=4............2
adding equation1 with equation 2
2x+y+3x-y=6+4
5x=10
x=10/5=2
substituting vslue of y in equation 1
2×2+y=6
y=6-4
y=2
