Hank has a board 1.75 meters long.He used 0.8 meter to build the walls of a birdhouse.He used 0.4 of what is left for the floor.He needs 0.6 meter for the roof.Does he have enough wood for the roof? EXPLAIN

Answers

He doesn't have enough wood for the roof explanation: If you subtract 0.8 from 1.75 that 0.95 if you then subtract 0.4 from 0.95 you get 0.55 so you can't subtract the last one 'cause if you do you'll get -0.05.

What is the value of x? 12-x=7

Answers

Answer: The value of x = 5.

Step-by-step explanation:

Given linear equation is 12-x=7 with variable x

To find the solution i.e. the value of x of the given linear equation, we need to perform following steps:

Step 1. Subtracting 12 from the both sides of the equation,we get

⇒12-x-12=7-12

⇒-x=-5

Step 2. Multiplying (-1) on the both sides ,we get

⇒-x × -1=-5 × -1

⇒x=5

So ,the value of x=5

Thus required solution of the given linear equation is x=5.

12-x=7. Well if you look at seven you should Be able to subtract 7 from 12 and get five.

You x Value = 5!

Ok so its fractions which fraction is bigger:
5/8 or 7/15 and its 5/8.
then is says 5/8=
and 7/15=
can somebody work it out. i think it means half it to simplify the answers.
this is the second question
2/15 or 4/25 which is bigger?
and then it says
2/15=
and 4/25=
can somebody pleeeeeeease help? thank you

Answers

First we have to find da Common Denominator:
5×15=75 7×8=56
- --- --- ----
8×15=120 15×8=120
So now u can tell dat 75/120 is bigger than 56/120. So da answer to this is 5/8 is bigger than 7/15.
For da second u need to do da same thing. Find da common denominator.
2×5=10 4×3=12
--- --- --- ---
15×5=75 25×3=75
Now u can see dat 12/75 is bigger. So u can say dat 4/25 is bigger than 2/15.
