Answer:

The surface area would be 248 square inches.

Step-by-step explanation:

To find the answer of this, use the formula for area of a rectangular prism.

SA = 2lw + 2lh + 2wh

SA = 2(10)(6) + 2(10)(4) + 2(6)(4)

SA = 120 + 80 + 48

SA = 248

100+30=130
100+40=140

online price is 130% or original
superstore price is 140% or original
the difference bewteen them is 140-130=10% of the original price

A. 1.3 times 160=208=online
1.4 times 160=224=superstore

B. difference is 224-208=16=10% of 160
it is 10% of the original price

A. online=$208
superstore=$224

B. $16, this is 10% of the original price

Solve the following system of equations.<br> 2x+y=3<br> I= 2y - 1<br> x=<br> y=

marin [14]

<em>Note: I am assuming your second equation is:</em>

<em>x = 2y - 1</em>

<em></em>

Answer:

The solution to the system of equations is:

x = 1

y = 1

Step-by-step explanation:

Given the system of equations

2x+y=3

x = 2y - 1

solving the system of equations using the elimination method

$\begin{bmatrix}2x+y=3\\ x=2y-1\end{bmatrix}$

Arrange equation variables for elimination

$\begin{bmatrix}2x+y=3\\ x-2y=-1\end{bmatrix}$

Multiply x-2y=-1 by2: 2x-4y=-2

$\begin{bmatrix}2x+y=3\\ 2x-4y=-2\end{bmatrix}$

subtracting the equations

$2x-4y=-2$

$-$

$\underline{2x+y=3}$

$-5y=-5$

now solve -5y = -5 for y

$-5y=-5$

Divide both sides by -5

$\frac{-5y}{-5}=\frac{-5}{-5}$

Simplify

$y=1$

For 2x+y=3 plug in y=1

$2x+1=3$

subtract 1 from both sides

$2x+1-1=3-1$

Simplify

$2x=2$

Divide both sides by 2

$\frac{2x}{2}=\frac{2}{2}$

Simplify

$x=1$

Therefore, the solution to the system of equations is:

x = 1

y = 1
