Answer:

Step-by-step explanation:
We can solve the problem in this way:
- The 1st information that we have is that the four numbers are even and consecutive integer. Let's call these numbers A, B, C and D. This means that:

(since the distance between two even consecutive numbers is 2)
- The 2nd information that is given is that the sum of the first and third multiplied by 3 equals 28 less than 5 times the fourth, so:
(1)
Now we rewrite eq(1) by using:

and
(obtained by combining the 3 first equations)
So we get:

Solving this equation for C,

So the other numbers are:

3/10 and 4/10 and 4/12 and 9/12
Answer:
60%
Step-by-step explanation:
first do 28+32.
Next it equals 60. So change 60 to percentage form. It would be 60%
Since complementary angles add to 90°, (4x - 1) and (5x + 19), also add to 90°.
Thus, lets form an equation:
90 = 5x + 19 + 4x - 1
72 = 9x
x = 9
Thus, the measure of angle B is 64°.
Answer:
x = 14
