We're asked to solve this system of equations:
\begin{aligned} 2y+7x &= -5\\\\ 5y-7x &= 12 \end{aligned}
2y+7x
5y−7x
=−5
=12
We notice that the first equation has a 7x7x7, x term and the second equation has a -7x−7xminus, 7, x term. These terms will cancel if we add the equations together—that is, we'll eliminate the xxx terms:
\begin{aligned} 2y+\redD{7x} &= -5 \\ +~5y\redD{-7x}&=12\\ \hline\\ 7y+0 &=7 \end{aligned}
2y+7x

Solving for yyy, we get:
\begin{aligned} 7y+0 &=7\\\\ 7y &=7\\\\ y &=\goldD{1} \end{aligned}

Plugging this value back into our first equation, we solve for the other variable:

We can check our solution by plugging these values back into the original equations. Let's try the second equation:
\begin{aligned} 5y-7x &= 12\\\\ 5\cdot\goldD{1}-7(\blueD{-1}) &\stackrel ?= 12\\\\ 5+7 &= 12 \end{aligned}

We can multiply the first equation by -4−4minus, 4 to get an equivalent equation that has a \purpleD{-16x}−16xstart color #7854ab, minus, 16, x, end color #7854ab term. Our new (but equivalent!) system of equations looks like this:

36y−16x+80

Adding the equations to eliminate the xxx terms, we get:

mrs hough is building a raised garden next to her 13.5 ft fence so she only needs fencing to go around the other 3 sides. if the area of the garden is 121.5 sw ft how much fencing does she need
Answers
Mrs. Hough would need 31.5 feet of fencing for the other three sides of the garden.
To calculate the amount of fencing needed for Mrs. Hough's raised garden, we first need to determine the dimensions of the garden.
Since the garden is next to a 13.5 ft fence, we know that one side of the garden is 13.5 ft.
Let's assume the other two sides of the garden have lengths x and y.
The area of the garden is given as 121.5 sq ft, so we have the equation:
x × y = 121.5
To find the dimensions of the garden, we can solve this equation. One possible solution is x = 9 ft and y = 13.5 ft.
Therefore, the dimensions of the garden are 9 ft by 13.5 ft.
Now, to calculate the amount of fencing needed, we add up the lengths of the three sides (excluding the side next to the fence):
Fencing needed = x + y + x = 9 ft + 13.5 ft + 9 ft = 31.5 ft
Mrs. Hough would need 31.5 feet of fencing for the other three sides of the garden.

this space shuttle to travel 7. 2 x 108 miles?
Answers
It would take 2 hours for this space shuttle to travel 7. 2 x 108 miles
As per the given data, a certain space shuttle travels at a speed of 3. 6 x
104 miles per hour.
Here we have to determine that how many hours would it take this space shuttle to travel 7. 2 x 108 miles.
The relation between the speed and the distance is:
Speed = Distance × Time
Speed = 3. 6 x 104 miles per hour
Time = 1 hour
3. 6 x 104 = Distance × 1
Distance = 374.4 miles
The distance to be covered 7. 2 x 108 miles
= 777.6 miles
Hours taken to travel 7. 2 x 108 miles.
Time = \(\frac{777.6 }{374.4}\)

A vehicle has a will 15 inches in diameter. If the vehicle travels 2 miles, how many revolutions does the wheel make? This is Applications of unit conversions
Answers
Find the circumference of the wheel:
Circumference = PI x Diameter = 3.14 x 15 = 47.1 inches.
Every revolution the tire travels 47.1 inches.
1 mile = 5,280 feet, so 2 miles = 5280 x 2 = 10,560 feet.
1 foot = 12 inches.
2 miles = 10,560 feet x 12 = 126,720 inches.
Revolutions = total distance / distance per revolution:
Revolutions = 126,720 / 47.1 = 2,690.45 revolutions ( round answer as needed.)
