Answer:
37 7/8
Step-by-step explanation:
First you make the equation
14 5/8 = _ - 20 - 3 1/4
They all have to make 14 5/8 so then solve
x+-93/4 = 117/8
x=303/8
Simplified:
x=37 7/8
210/600 = 35% B
1/4 of 600 = 150 C
Answer:
4
Step-by-step explanation:
Simplify the following:
2^5/2^3
Hint: | For all exponents, a^n/a^m = a^(n - m). Apply this to 2^5/2^3.
Combine powers. 2^5/2^3 = 2^(5 - 3):
2^(5 - 3)
Hint: | Subtract 3 from 5.
5 - 3 = 2:
2^2
Hint: | Evaluate 2^2.
2^2 = 4:
Answer: 4
Answer:
(-8,-10)
Step-by-step explanation:
we have the two equations x-2y=12 and y=3x+14.
I'm going to assume this is a system of equations and we are looking for the solution.
we can use the substitution method as y is "defined".
x-2y= 12
substitute y = 3x + 14
x-2(3x+14)=12
distribute
x - 6x -28 = 12
combine like terms
-5x - 28 = 12
add 28 to both sides
-5x = 40
divide both sides by -5
x = -8
Now we plug in the value of x into one of the equations and solve for y
y = 3x + 14
x = -8
y = 3(-8) + 14
y = -24 + 14
y = 10
the solution is (-8,-10)
