3 consecutive even integers.....x, x + 2, and x + 4
1/2(x + 2 + x + 4) = 65....multiply both sides by 2, canceling out 1/2
x + 2 + x + 4 = 65 * 2
2x + 6 = 130
2x = 130 - 6
2x = 124
x = 124/2
x = 62
x + 2 = 62 + 2 = 64
x + 4 = 62 + 4 = 66
so ur numbers are : 62,64,66 <==
Answer:
C
Step-by-step explanation:
C 160/2 = 80
240/3 = 80
400 / 5 = 80
480 / 6 = 80
C is linear
Answer:
slope- 9 y-intercept- -7
Step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
Answer:
2/5
Step-by-step explanation:
25% is equal to 1/4
Lets think of this as money
If we take .25 and multiply it by 4 we get 100 or 1.00
Lets take 5/20
5/20 is also equal to 25%
For this one, let's change the fraction to an equivalent fraction. To do this I'm going to multiply both the top and bottom by 5.
5*5/20*5
That gets us 25/100
Back to thinking money-- we know that 25/100 is equal to 25%
25/100
We just determined that 25/100 is 25% using the problem above.
-----------------------------------------------------------------------------------------------------------------
The odd one out-- 2/5
2/5 is equal to 40%
If we think of this fraction as money and we get an equivalent fraction-- 40/100
We can clearly see that that is not 25/100, 1/4, 5/20, or even 25%
Hence making it not equivalent to 25%
Hope this helps! Feel free to ask questions in the comments!
7.
If c = 16
that means the equation is
16 - 9
which is 7
so 7
