Answer:
28, 30, 32
Step-by-step explanation:
Three consecutive even numbers are three even numbers that are next to each other. For example, 2, 4 and 6 would be 3 consecutive even numbers.
With this sort of problem, you want to try to let each number be equal to one thing and then construct the same number of equations as you have variables:
Let's let,
Integer 1 = X
Integer 2 = Y
Integer 3 = Z
X + Y + Z = 90
We also know, that
Y = X + 2
And that
Z = X + 4
Now, we can sub these equations into the first equation. We do this so that we have everything represented as the same variable.
90 = X + (X+2) + (X+4)
90 = 3X + 6
84 = 3X
28 = X
So, the numbers are 28, 30 and 32
It would cost about $.50 because $8.15 rounds to $8.00, and 8/16 = 0.5
First thing is to multiply 3 by x and get 3x,then 3 by 4 equals 12. 3x+12....6x=3x+12...subtract 3x from 6x and get 3x=12..then divide 3 on both sides and 3x crosses out.. and x=4...this is what I have to say about this..
Answer:
x =12
Step-by-step explanation:
we have:
-2(4-x)-5=11
apply distributive property:
-2*4 +2*x -5=11
we have:
-8 +2x -5 =11
2x -13 =11
2x = 11+13
2x= 24
x = 24/2
finally we have the x value:
x =12
−5 < a − 4 < 2
+4 +4
-1 < a < 6
Answer is B. The second one
