Answer:
x = 22
Step-by-step explanation:
(x+1)+(3x+1) = 4x+2
4x+2=90°
Solve for x:
4 x + 2 = 90
Subtract 2 from both sides:
4 x + (2 - 2) = 90 - 2
2 - 2 = 0:
4 x = 90 - 2
90 - 2 = 88:
4 x = 88
Divide both sides of 4 x = 88 by 4:
(4 x)/4 = 88/4
4/4 = 1:
x = 88/4
The gcd of 88 and 4 is 4, so 88/4 = (4×22)/(4×1) = 4/4×22 = 22:
Answer: x = 22
X = 89
41 + 50 = 91 which is 89 away from 180
Answer:
9 11/12
Step-by-step explanation:
Solve 7 2/3-1 2/4+3 6/8
We are to the above fractions
7 2/3 - 1 2/4 + 3 6/8
The Lowest Common Denominator = 24
(7 - 1 + 3) + ( 2/3 - 2/4 + 6/8)
9 + (16 - 12 + 18/24)
9 + 22/24
9 11/12
40/60=60/x...forty miles in sixty minutes is equal to 60 miles in 40 minutes.....40x=3600....x=90..90 minutes
