The answer is d. All ratios on the chart divide out to 3.5 as d does the same
Answer: 49/30 or, 1 19/30
Answer: 317.39
Step-by-step explanation:
The price of the guitar decreased by15%
Original price is 275.99
To get the reduced amount
It will be 15% of the exact amount and add to the exact to get the original
15/100×275.99
=41.3985
To get exact,
reduced amount + sold price
=41.3985+275.99
=317.3885
=317.39

in the solution to the second equation at the end of Step 1 and calculate x:
x=−5−(3×−2)
x=−5−(−6)
x=−5+6
x=1
The solution is x=1 and y=−2
