The answer is C. because its 73 is after the 19 is subtracted
I'll give you a study tip. If you actually just break down the problem it's much easier. See how it says 5 tens, it's basically asking you what is 5 times 10
Answer: 11/10 or 1 1/10 pages
Step-by-step explanation:
3/5 + 1/2 = x
find the LCD so that you can add the fractions.
3/5 (2/2) = 6/10
1/2 (5/5) 5/10
6/10 + 5/10 = 11/10 or 1 1/10
X + Y = 18
X=chickens, Y=Cows
2x + 4y = 60
Let's try 8 and 10.
16 + 40=56, no, 32+20=52, no. 8&10 do not work.
Let's try 9 and 9.
18+36=54, no. 9&9 do not work.
Let's try 11 & 7.
22+28=50, no. 14+44=58, no.
Let's try 12 & 6.
24+24=48, no. 12+48=60 YES!
There are 12 cows and 6 chickens.
Answer:
x = -26
Step-by-step explanation:
Multiply both sides by the lowest common multiple of 4 and 3, which is 12.
3(x+2) = 4(x+8)
3x + 6 = 4x + 32 --- distribute the 4 and 3
6 = x + 32 --- subtract 3x from both sides
-26 = x --- subtract 32 from both sides
x = -26
