Answer:
There are 25 chickens and 20 rabbits
Step-by-step explanation:
Let
x-----> the number of chickens
y ----> the number of rabbits
Remember that
1 chicken has two legs
1 rabbit has four legs
so
2x+4y=130 -------> equation A
x=y+5 -----> equation B
Substitute equation B in equation A and solve for y
2(y+5)+4y=130
2y+10+4y=130
6y=120
y=20 rabbits
Find the value of x
x=y+5
x=20+5=25 chickens
Answer:
:)
Step-by-step explanation:
Examples: 1+2, 1/3+1/4, 2^3 * 2^2
(x+1)(x+2) (Simplify Example), 2x^2+2y a x=5, y=3 (Evaluate Example)
y=x^2+1 (Graph Example), 4x+2=2(x+6) (Solve Example)
To get the price of the new item after an increase of 10% you would have to find 10% of whatever the price is and add it to the original price so for example say the price is $300 you would do 300*0.10(0.10 is 10%) which is 30 and add that to 300 so the new price would be $330
Answer:
19, because it wouldn't be close to becoming a whole.
Step-by-step explanation:
You can round each number to the nearest half
12 3/8 = 12 1/2
6 7/8 = 7
Now, you have: 12 ½ × 7
Since you have a mixed number, change it to a decimal to make it easier.
12 ½ = 12.5
12.5 × 7 = 87.5
The product of 12 3/8 and 6 7/8 is about 87 1/2 = 87.5
