Let's do subtraction by first starting with the ones place and then the tenths place of the subtrahend.
45-4=41; 44, 43, 42, 41
41-.5= 40.5; 40.9, 40.8, 40.7, 40.6, 40.5
45-4.5=40.5
We can check by using addition.
40.5+4.5=
44+1=
45
Step 1: Simplify both sides of the equation.
−36=p−30
Step 2: Flip the equation.
p−30=−36
Step 3: Add 30 to both sides.
p−30+30=−36+30
p=−6
2.20 rounded to the nearest tenth is 2.2 it is already rounded if it was 2.29 it would be 2.3
Answer:
x = 87/28
Step-by-step explanation:
So the equation is x + 2x + 5= 29
Here are the steps -5 -5
-----------------------
3x = 24
Divide both sides by 3 so you get
x = 8
Then look back at the question, the second number has to be twice that number plus 5
So the 1st number is 8 The second # is 2(8)+5= 21
