5x+12-8x=-24 steps by step please
Step-by-step explanation:
=>first combine the like terms5x-8x+12=24
-3x+12=24
=>substruct 12 from 12 and 24-3x+12-12=24-12
-3x=12
=>divide -3 from both side-3x/3=12/-3
=-4Answer is x = 12 :)
Operations you're supposed to do in order to solve this equation are:
1. Combine like terms
2. Subtract 12 from both sides
3. Simplify
4. Divide both sides of the equation by the same term
5. Simplify.

y varies directly with x. If y = 15 when x = -18, find y when x = 1.6.
Answer:
y= -1.328
Step-by-step explanation:
15= k*-18
15=k*-18 (divide both sides by -18)
It doesn't go in evenly so you are left with a negative decimal
k= -0.83
Now find y
y= -0.83(1.6)= -1.328

whats 7 over 4 =35 over m in solving proportions NO LINKS PLZ
Hey there!
7/4 = 35/m
CROSS MULTIPLY BOTH of your NUMBERS
7(m) = 4(35)
7(m) = 7m
4(35) = 140
NEW EQUATION: 7m = 140
DIVIDE 7 to BOTH SIDES
7m/7 = 140/7
CANCEL out: 7/7 because that gives you 1
KEEP: 140/7 because that gives you the value of m
140/7 = m
Solve above and you have the answer of m
140/7 = 20
Therefore, the value of m = 20
Answer: m = 20

The ratio of length to width in a rectangle is 3 to 1. If the perimeter of the rectangle is 120 feet, what is the length of the rectangle?
Answer:
a = length
b = height(width)
a=3b
2(a+b)=120
2(b+3b)=2(4b)=8b
8b=120
b=15
a=45
length is 45 feet
width is 15 feet

A. 157 cm
B. 45 cm
C. 135 cm
• D. 180 cm
9514 1404 393
Answer:
B. 45π cm^3
Step-by-step explanation:
The volume is given by ...
V = 1/3πr^2h
where r is the radius (half the diameter) and h is the height. With the given numbers, we have ...
V = (1/3)π(3 cm)^2(15 cm)
V = 45π cm^3 . . . volume of each cup

Answer:
x = 17
y = 8
QPR = 35º
QRP = 60º
Step-by-step explanation:
2x + 1 = x + 18
Subtract x from both sides
x + 1 = 18
Subtract 1 from both sides
x = 17
QPR = 2x + 1
QPR = 2(17) + 1
QPR = 35º
-------------------------------
8y - 4 = 4y + 28
Subtract 4y from both sides
4y - 4 = 28
Add 4 to both sides
4y = 32
Divide both sides by 4
y = 8
QPR = 8y - 4
QRP = 8(8) - 4
QRP = 60º

In the figure below, mLJK = 37° and mKLJ = 69°.
Answer:
C
Step-by-step explanation:
ΔJKL consist of 3 angles: ∠mLJK, ∠mKLJ and ∠mJKL
We are given the measures of ∠mLJK and ∠mKLJ
In order to find ∠mJKH we must find the missing angle in the triangle
Remember that angles in a triangle add up to equal 180
If we are given two angles we can find the missing angle by subtracting the measures of the known angles from 180
so ∠mJKL = 180 - 37 - 69
180 - 37 - 69 = 74
Hence, ∠mJKL = 74°
Now to find ∠mJKH
Angles ∠K, ∠mJKH and ∠mJKL appear to be formed on a straight line
Angles formed on a straight line add up to equal to 180
So ∠K + ∠mJKH + ∠mJKL = 180 ( note that this is the equation that will be used to solve for ∠mJKH )
∠K is a right angle, indicated by the little square.
Right angles have a measure of 90° so ∠K = 90
We have also calculated the measure of ∠mJKH = ( 74° )
That being said we plug in the given values into the equation created earlier and solve for ∠mJKH
We would have 90 + ∠mJKH + 74 = 180
Now we solve for ∠mJKH
step 1: combine like terms
90 + 74 = 164
now we have 164 + ∠mJKH = 180
step 2 subtract 164 from each side
180 - 164 = 16
164 - 164 cancels out
we're left with ∠mJKH = 16
Hence the answer is C
