The answer is 3 :) hope helps
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:
z=40 degrees
x=90 degrees
y=40 degrees
Step-by-step explanation:
To solve z you know that 50+90+z= 180 degrees. So z equals 40. To solve x you subtract 90 from 180 to get 90 degrees. To solve you add 50+x+y. You know that x= 90. You would add the angles together to get 180 degrees. 50+90=140 and 180-140 equals 40. Sorry if i'm wrong.
To complete the square we get the coefficient of x, divide it by 2 then square it.
-3/4 divided by 2 =
-3/8 and then squared it equals
9 / 64
answer is a
2 is a multiple of 4, so anything that's a multiple of 4 will automatically be a multiple of 2
so 3 x 4 = 12
so multiples of 12 that are between 67 and 113 are...?
12 x 6 = 72
12 x 7 = 84
12 x 8 = 96
12 x 9 = 108 <span> 72 or 84 or96 or 108
all are divisible by 2,3 and 4
all fall between 67 and 112</span>
