Answer: 3.875 or 3ft 7/8in
=15.5 - 3.875(3)
=15.5 - 11.625
= 3.875 or 3ft 7/8in
Answer:
x=−3
Step-by-step explanation:
2(6x+1)−4(x−5)=−2
Step 1: Simplify both sides of the equation.
2(6x+1)−4(x−5)=−2
(2)(6x)+(2)(1)+(−4)(x)+(−4)(−5)=−2(Distribute)
12x+2+−4x+20=−2
(12x+−4x)+(2+20)=−2(Combine Like Terms)
8x+22=−2
8x+22=−2
Step 2: Subtract 22 from both sides.
8x+22−22=−2−22
8x=−24
Step 3: Divide both sides by 8.
8x/8=−24/8
Given the ratio of cars, trucks and motorcycles 7:5:2 and the total number of cars is 48, to get the number of motorcycles we proceed as follows:
fraction of cars to total number
(5+7)/(7+5+2)
=12/14
=6/7
the total number of cars, trucks and motorcycles will be:
1/(6/7)×48
=56
total number motorcycles
2/14*56
=8 motorcycles
Answer:
x = 2
y = 5
Step-by-step explanation:
3x + y = 11 equation (1)
-x + y = 3 multiply this equation by -1
x - y = -3 equation (2)
by adding 2 equations
4x = 8
x = 2
by sub. in Equation (2)
2 - y = -3
y = 2+3
y = 5
