Answer:
Step-by-step explanation:
9 * 44 =
9 (40 + 4) =
9(40) + 9(4) =
360 + 36 = 396
The original expression evaluates to 54.4 as shown in the first working.
_____
For some reason, 3.4 got transcribed to be 1.7 in the 3rd line of the second working. There is no math operation in the expression that requires 3.4 to be divided by 2.
2x+3y=36
2x=36-3y
y=6
2x=36-3*6
2x=36-18
2x=18
x=18:2
x=9
-8h = -32.8
First, divide both sides by -8. / Your problem should look like: h = 4.1
Answer: h = 4.1
