F(g(2))
g(2)=2^2+1=4+1=5
f(5)=5-3=2
f(g(2))=2
The order of operations is PEMDAS (parenthesis, exponents, multiplication/division, addition/subtraction). This means that you do multiplication before adding, so 3 + 4*6 is the same thing as 3 + (4*6). Because of this, Omar did not need to use a grouping symbol.
To do this problem you use is/of=percent/100
So:
320/750=x/100
cross multiply
32,000=750x
divide both sides by 750
x=42.66 repeating
ANSWER: X=42.66 REPEATING
Remember you can do anything to an equation as long asyou do it to both sides
4x+2(x-3)=3x+x-12
distribute and expand
4x+2x-6=4x-12
6x-6=4x-12
minus 4x both sides
2x-6=-12
add 6 both sides
2x=-6
divide by 2
x=-3
A is the answer
Answer:
<h2>48</h2>
Step-by-step explanation:
so for every 3 Reid washes there are 4 Elsie washes
the ratio of washing is 3:4
lets add 3 and 4 up
3 + 4 = 7
now lets divide the total number of washes by the added ratio
84/ 7
=12
now we know that 1 part is 12
to find Elsie's part we need to x 12 by how many parts she has got
she washed 4 times
4 x 12
=48
