Rewrite the first equation as y = -x+10
plug in this equation into y in the second equation
solve for x
x = 34
plug x=34 into the first equation
solve for y
y = -24
THE ANSWER IS: (34,-24)
Brand X cost: $4.50
Brand Y cost: $3.50
Christopher spends total: $49.50
Equation: 4.50x + 3.50y = 49.50
Idk how to solve the equation but this should be the correct equation
Answer:
2x-5y
Step-by-step explanation:
9x-7x= 2x
3y-8y= -5y
Based on the given figure above, here is how you get the area.
Firstly, you get the area of the part with the measurement of 4m and 4m. This has the same measurement of the sides so it is easier to find the area. The formula for the area of the square is s x s. So 4m x 4m is 16m^2. Next, get the area of the rectangle part. Getting the area of the rectangle is l x w. So 9m x 10m would be 90m^2. Now add both values and you get 106m^2. So the answer is option B.
