Let's call the number x
4x - 24 = -2x + 30
+ 2x
6x - 24 = 30
+ 24
6x = 54
÷ 6
x = 9

So x is 9, and the equation is 4x - 24 = -2x + 30, I hope this helps!

Can someone explain this to me
Lynna [10]

Answer:

\huge\boxed{\sf tan \ 28 = x / 14}

Step-by-step explanation:

Since opposite and adjacent is given, we will use tan as trigonometric ratio.

Hence,

opposite = x , adjacent = 14 and \theta = 28

So,

\sf tan \theta = opposite / adjacent

tan 28 = x / 14

\rule[225]{225}{2}

Hope this helped!

A father’s age now is three times the age that his son was 4 years ago. In
Mice21 [21]
Let ‘s’ be the son’s age 12 years ago.
Let ‘f’ be the father’s current age.

4 years ago, the son was:

s-4

So, his father is currently:

3(s-4)

=

3s-12

Therefore:

f = 3s-12

In twelve years, the son will be:

s+12

And the father will be:

f+12

This can also be written as:

3s-12+12 as the fathers younger age would be f = 3s+12

=

3s

So, we know that s+12 is half the fathers current age, meaning the father is currently 2(s+12) which is equivalent to 2s+24. Also, we know that the father is currently 3 times the sons age 12 years ago, so 3s (proven by the calculations we made above). Therefore, 2s+24=3s which means 24=s. We can then substitute this, and we will receive 24+12 = 36

Son’s current age: 36

We then substitute the son’s age 12 years ago into 2s+24 to give us the father’s age.

2(24)+24 = 72

Father’s current age: 72
