Answer:
what you do is you want to get the x by it self so you would subtract the x and put it on the other side. like this: 10y=-9-x. OK so you would subtract -9 and put it on the other side like this: 9 + 10y=-x. but you can't have a negative x so u would do -9 + 10y=x.

Answer: The volume is 40 cubic inches
Step-by-step explanation: Each toy block is 1 cubic inch, which means each toy block is a cube with all sides (Length, width and height) measuring 1 inch. That makes the volume of each cube or block to be derived as;
Volume = L x W x H
Volume = 1 x 1 x 1
Volume = 1 cubic inch
The first 3 floors are made up of six rows of four blocks. This means, the first 3 floors has six by four blocks, that is, six times four blocks and that gives us 24 blocks.
The fourth to eighth floors are made up of four rows of four blocks. This also means four by four blocks, that is, four times four blocks and that gives us 16 blocks.
Having determined the amount of blocks used in the total model building as
1st - 3rd = 24 blocks
4th - 8th = 16 blocks
The total number of blocks used is 24 plus 16 which equals 40. Having been told that each block has a volume of 1 cubic inch, the volume of the model building equals 40 cubic inches.
Answer:
Step-by-step explanation:
First, find the LCM and multiply through:
The LCM will cancel out the denominators (note that braket symbolizes Multiplication):
:3(2x-1) +4(x)=24
:6x-3+4x=24
Group like terms:
6x+4x=24+3
10x=27
Divide through by 10 to eliminate the coefficient of x
: x=
4.9 convert it fraction = 49/10
Answer:
your answer is 6 hours
Step-by-step explanation:
you have the 2nd pipe takes 72 hours so then you multiply 4 x 9 x 12 which is 432 and then you divide 432 by 72 which is 6 so it would be 6 hours
hope it helps ^^
