Step-by-step explanation:
−2x+5y=−15 and 5x+2y=−6
Rewrite equations:
−2x+5y=−15;5x+2y=−6
Step: Solve−2x+5y=−15for x:
−2x+5y=−15
−2x+5y+−5y=−15+−5y(Add -5y to both sides)
−2x=−5y−15
−2x−2=−5y−15−2(Divide both sides by -2)
x=52y+152
Step: Substitute52y+152forxin5x+2y=−6:
5x+2y=−6
5(52y+152)+2y=−6
292y+752=−6(Simplify both sides of the equation)
292y+752+−752=−6+−752(Add (-75)/2 to both sides)
292y=−872
292y292=−872292(Divide both sides by 29/2)
y=−3
Step: Substitute−3foryinx=52y+152:
x=52y+152
x=52(−3)+152
x=0(Simplify both sides of the equation)
Answer:
x=0 and y=−3
Answer: 89,998,910
Step-by-step explanation: if she gives 1900 away and keeps 900 then I’m assuming she gives the rest away to charity and that would be 89,998,910 apples
Answer:
She gave 89997200 apples to charity
Step-by-step explanation:
90000000 - 1900 - 900 = 89997200
or

Step-by-step explanation:
The classroom wall has an area of .
The fire code requirements allow a bulletin board with an area of at most 30% of . This means that the maximum area of the bulletin board is
Let L and W be the length and wide of the bulletin board.
If the length of the board is three times as long as the width, then L=3W, and the area of the board is
For the largest board we have,
So, the largest bulletin board that meets the fire code is 3 ft. wide and 9 ft. long.

Step-by-step explanation:
If you add up the dowton and center city locations and then subtract that from the amount of pizzas at the westland location, you get your answer
The Westland location needs to sell 25 more pizzas to equal the sales of the downtown and center city locations.
To determine how many more pizzas the Westland location needs to sell to equal the downtown and center city locations, you would need to know the number of pizzas sold at each location. Let's say the downtown location sold 100 pizzas and the center city location sold 75 pizzas. To equalize the sales, the Westland location would need to sell the difference between the two, which is 25 pizzas.
