5x+3y=58
5x-3y=22
(3y gets cancelled bc 3y-3y=0, then add 5x with 5x, so you're left with)
10x=80, (divide both sides by 10)
x=8
Now we look for y. So choose one formula from the two (let's say 5x + 3y=58)
Substitute x for 8 so it will look like---- 5(8)+3y=58
Multiply 5*8--- so you get -- 40+3y=58
Subtract 40 from both sides and you're left with 3y=18
divide both sides by 3
you get y=6
In conclusion, x=8 and y=6 hence, (8,6)
Answer:
45.3191
Step-by-step explanation:
0.0229 is 100 times smaller that 2.29 but 1979 is 100 times greater than 19.79. Since they cancel each other out, the answer remains the same.
Answer: 3
Step-by-step explanation:
Since the denominator of the two fractions are already the same, we do not have to alter the fractions at all
Because the denominators are the same, all we have to worry about is the numerator, so take 67 and subtract 43 from it to get 24
As you know, 24/8 = 3, and that would be your final answer
Answer:
B I think or C or D or it could be A
