Help me find the value of "y" thanks

Answers

You would move you positive 3 to the left side so (y) is by itself. So you would have 3x-8=y. Then substitute X=5. So 3(5)-8=y. 15-8=y. 7=y

Answer:

[tex]y=3x-8[/tex]

Step-by-step explanation:

First, you have to isolate y on one side of the equation.

Step 1) Add 5 to both sides (this will cancel out the (-5) on the left)

Step 2) Subtract 3x from both sides (this will cancel out the (3x) on the left)

Step 3) Subtract y from both sides

Step 4) In order to make the desired variable positive, change the sign of everything in the equation

The step shown above will yield the answer of [tex]y=3x-8[/tex]

What percentage of this grid is shaded?
b)
How many more squares need to be shaded
so that 80% of the grid is shaded?

Answers

Answer:

52% of the grid is shaded. You would need 7 more squares in order to get 80%.

Step-by-step explanation:

There are 25 boxes. You want to figure out how much each box is worth.

So,

You divide 100 by 25. You will get an answer of 4.

So now you know how much each box is worth.

There are 13 boxes shaded in, so you multiply 13 by 4 to get 52.

Keep adding boxes in order to get 80%. For example, 52%, 56%, 60%, until you get to 80%. Then see how many boxes you added up to get 80%.

We would need 7 more squares in order to get 80%. Thus, 52% of the grid is shaded.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

There are 25 boxes. we want to figure out how much each box is worth.

So,

100 / 25 = 4

Now, we know how much each box is worth.

There are 13 boxes shaded in,

so 13 x 4 = 52.

Keep adding boxes in order to get 80%.

For example, 52%, 56%, 60%.
