Answer:
6w + 2a = 28
Step-by-step explanation:
the expression given, 6w + 2a, contains no variable h, so it's best to just ignore that h = 5.
first, plug in the values for w and a. you can do this in whatever order you want, but i'll start with w for this example.
plug in 4 for w.
6w + 2a
6(4) + 2a
now plug in 2 for a.
6(4) + 2a
6(4) + 2(2)
after plugging in the values, your expression is 6(4) + 2(2).
all that's left is to simplify. again, this can be done in whatever order you prefer, but i'm going to start with 6(4).
6(4) + 2(2)
24 + 2(2)
continue simplifying by multiplying 2(2).
24 + 2(2)
24 + 4
now add 24 + 4.
24 + 4 = 28
so, when w = 4 and a = 2, 6w + 2a = 28.
you can check the answer by plugging those values for a and w back into the completed equation.
6w + 2a = 28
6(4) + 2(2) = 28
24 + 4 = 28
28 = 28
since both sides of the equation are equal, that means that your answer of 28 is correct! :)

Answer:
70/9
Step-by-step explanation:
Let's solve your equation step-by-step.
4−138=6(1−3x)
Step 1: Simplify both sides of the equation.
4−138=6(1−3x)
4+−138=(6)(1)+(6)(−3x)(Distribute)
4+−138=6+−18x
(4+−138)=−18x+6(Combine Like Terms)
−134=−18x+6
−134=−18x+6
Step 2: Flip the equation.
−18x+6=−134
Step 3: Subtract 6 from both sides.
−18x+6−6=−134−6
−18x=−140
Step 4: Divide both sides by -18.
−18x/-18=−140/-18
x=70/9
a. 9 ones, 36 hundredths = 3 ones, 12 hundredths = 3.12
b. 36 ones, 012 thousandths = 12 ones, 004 thousandths = 12.004
c. 35 tenths, 5 hundredths = 71 hundredths = 0.71
d. 3 ones divided by 5 + 545 thousandths divided by 5 = 709 thousandths = 0.709
