To simplify that expression you'll join like terms.
8x + 4 - 5
8x - 1
88% of 300
0.88 x 300 = 364

24 out of 120
24 / 120 = 0.2
Move the decimal two places to the right: 20.
20%
-
3 is 12% of (unknown number)
12% × x = 3
or 12 / 100 × x = 3
Multiplying both sides by 100 and dividing both sides by 12,
we have x = 3 × (100/12)
x = 25

Not sure on question five. Never got those right as a kid, and I sure won’t get them now, lol
The value of the function f(g) after simplifying and putting 2 in place of <em>x</em> is -20 and the value of f(g(2)) is 418.
<h3>What is composite function?</h3>
When a function is written inside the another function, then such function is called the composite function.
The first function given in the problem is,
The second function given,
To find out the value of g(2), put the 2 on place of variable x in the above equation as,
The composite function f(g(x)) can be given as,
Thus, the value of the function f(g) after simplifying and putting 2 in place of <em>x</em> is -20 and the value of f(g(2)) is 418.

Answer:
r = 19.2deg
Step-by-step explanation:
6r + 5 = 30 + 90 (exterior angles of a triangle)
6r = 115
r = 19.2deg (1dp)

<h3>I'll teach you how to solve 8x² = 15 - 14x</h3>
----------------------------------------------------
8x² = 15 - 14x
Add 14x to both sides:
8x^2 +14x =15-14x+14x
Simplify:
8x^2 +14x =15
Subtract 15 from both sides:
8x^2+14x-15 = 15-15
SImplify:
8x^2+14x-15 = 0
Solve with the quadratic formula:
x= = 3/4
x= = -5/2
The solutions to the quadratic formula are:
x= 3/4, x=-5/2
Your Answer Is x= 3/4, x=-5/2
