You need two equations to solve a two-variable equation.
Answer:
a
Step-by-step explanation:
because 8-2 is 6. and 8 times 5 is 30.
A.You have to multiply the Original price(96) by todays discount(1/2)
96×(1/2)=48
Then to find the price 5 days from now you multiply the Original price(96) by the discount 5 days from now(2/3) but this time you subtract what you get from the original price 96×(2/3)=64
96-64=32 or the price of the coat 5 days from now
B. To find how much she would save subtract todays price(48) by the price 5 days from now(32)
48-32=16 She would save 16 dollars
Answer:
HJ = 33
Step-by-step explanation:
Given that point I is on segment HJ, then
HJ = HI + IJ ← substitute values
3x - 9 = x + x + 5, that is
3x - 9 = 2x + 5 ( subtract 2x from both sides )
x - 9 = 5 ( add 9 to both sides )
x = 14
Hence
HJ = 3x - 9 = (3 × 14) - 9 = 42 - 9 = 33
20× 8 = 160
160 + 2x > or = 500
-160--------------- -160
2x > or = 340
÷2------------÷2
x > or = 170
She has to sell at least 170 cupcakes to make $500 in profit.
Hope this helps!
