Step-by-step explanation:
the first one if you are solving for x it will be x=21-8y
if you are solving for y it will be y =21/8 - x/8
the second one will be if you are solving for x x = 2 -5y/3
solving for y is y=6/5-3x/5
Answer: No solutions
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
0.5x+0.5x=x+1
(0.5x+0.5x)=x+1(Combine Like Terms)
x=x+1
x=x+1
Step 2: Subtract x from both sides.
x−x=x+1−x
0=1
So, she paid (75-17.34=57.66) for the purchase
Or, the jeans costed 57.66-3.26=54.4 (prize minus sales tax)
But she got a 10 dollars off! so that means that the jeans actually costed 64.4
now, the 64.40 was the prize discounted by 30%:
64.40=(100-30)%*x
where x was the original prize
64.40=0.7x
644=7x
x=644/7
x=92
so the original prize was 92 dollars.
Answer:
isn't it that a parallelogram has 6 sides and these are 4?????????............
Answer:
b
Step-by-step explanation:
y2-y1/x2-x1
memorize this formula so you always know slope for 2 points given.
y is the second number in parentheses.
whichever you choose as y2 or y1, the x values will match those numbers as well.
(y2-y1) = (1-5)
(x2-x1) = (2+4)
(-4)/6
-2/3
