As parallel sides

\\ \rm\longmapsto 2x+90=180

\\ \rm\longmapsto 2x=90

\\ \rm\longmapsto x=90/2=45

Now

\\ \rm\longmapsto 2x+3y+6y+90=360

\\ \rm\longmapsto 9y+180=360

\\ \rm\longmapsto 9y=180

\\ \rm\longmapsto y=20

Answer:

2x + 90 = 180 \\ 2x = 90 \\ x =  \frac{90}{2}  = 45. \\ now \\  \\ 2x + 3y + 6y + 90 = 360 \\ 9y + 180 = 360 \\ 9y = 180 \\ y = 20.

Using algebraic expressions, the value of x in the diagram given is calculated as: x = 4

<h3>What is an Algebraic Equation?</h3>

An algebraic equation is an equation that has an unknown variable (i.e. x) and digits, which can be used to solve a problem.

Algebraic expression for Mat A is: 4x + 3

Algebraic expression for Mat B is: 2x + 11

We would have the following algebraic equation:

4x + 3 = 2x = 11

Solve for the value of x

4x - 2x = 11 - 3

2x = 8

x = 8/2

x = 4

Best estimate for 61/7
Ne4ueva [31]

I would say the best estimate would be 9 because the real answer is 8.71 and if you round that to the 1 place the answer would be 9.

Assume that price is an integer variable whose value is the price (in US currency) in cents of an item. Assuming the item is pai
cestrela7 [59]

Answer:

Change = (Paid*100) - Price

Step-by-step explanation:

First of all we need to know the relation between 1 dollar and 1 cent in order to express everything in the units required in the question.

We know that 1 dollar = 100 cents, so the amount paid for the item with single dollars has to be multiplied by 100 to express its value in cents.

Paid_{cents}=Paid_{dollars}*100

Now that we have everything in cents, we can make the subtraction:

Change_{cents} = Paid_{cents} -Price_{cents}

Replacing the value in cents we get:

Change = (Paid*100) - Price
