Okay, so since both y values share the same number, let's add both equations so the y values cancel out leaving us to solve for x.
10x+(-5x)=5x
7y+(-7y)=0
1+24=25
Now we have 5x=25
divide both sides by 5 and we have x=5
Now that we know x=5, we can plug it into one of the problems to find y.
Let's do 10(5) +7y=1
50+7y=1 subtract 5 and we get 7y=-49
divide -7 from both sides and we get y=-7
so there you have it x=5 and y=-7
I believe it’s D bc I went over A and it doesn’t add up
Answer: 12%
Step-by-step explanation: % = whole/part
400/48 = 0.12
0.12 x 100 = 12%
Answer:
ok
Step-by-step explanation:
mark me the brainlieast since your question is incomplete
So we know that 20% off means that it has 80%, and I just need to take $3.5×80÷100=$2.8 for the new price. Additionally, another 10% off which means that 2.8×90÷100=$2.52 for the final price. Hope it help!
