69 - 3a = 0
69 - 3a (-69) = 0 (-69)
-3a = -69
-3a(/-3) = -69(/-3)
a = 23
hope this helps
What you gotta take from this problem:
What Joe got during break =

What his sister gave him =

What he has total = 10 tadpoles.
Now to assemble this equation:

Now combine like terms to get

Subtract 2 on each side of the equation to get

Now you would divide 5 on each side and get

, however since you can't have a .6 of a tadpole, you would have to round it up to 2.
Temperature goes down up to 10° Celsius during the night.
Given that;
Temperature drop from 5º Celsius to -5º Celsius
Find:
Change in temperature in Celsius
Computation:
Change in temperature = Initial temperature in Celsius + Final temperature in Celsius
Change in temperature = 5 - (-5)
Change in temperature = 5 + 5
Change in temperature = 10° Celsius

The sum of two consecutive even integers is at most seven more than half the sum of the next two consecutive even integers
two consecutive even integers: n, n+2
next two consecutive even integers n+4, n+6
n+(n+2) >= 7+1/2(n+4 +n+6)
combine like terms
2n+2 >= 7 +1/2(2n+10)
distribute 1/2
2n+2 >= 7+n+5
2n+2>= n+12
subtract n from each side
n+2>= 12
subtract 2 from each side
n>10
4 integers : 10, 12 ,14, 16
We will calculate this by using ratios and because these two triangles are similar, which is very important.
Explanation:
We see that the FG = 9 corresponds to the VU = 21. Therefore, FH = 18 corresponds to the UW = x.
9 : 21 = 18 : x
x = (21*18)/9
x = 378/9
x = 42.
The correct answer is B. 42.
