You do 2x20 which is basically 2x2 (4) add a zero and your answer is 40
Answer:
Work in Parenthesis
2. 43.75 (.35*125)
3. 156.4 (.46*340)
4. 117 (.65*180)
5. 54 (.75*72)
6. 550 (99/.18)
7. 375 (345/.92)
8. 260 (143/.55)
9. 300 (141/.47)
Step-by-step explanation:
First 4:
multiply percent by total
alternate: convert % to decimal by /100, then multiply by total
Last 4:
ex. X * 18% = 99, so divide by 18% (or .18)
The first answer is A because (b+6) represents the sidewalk length. (With the pool length and the two corners, which equal 3 ft each.) Then, the sidewalk width would be (h+6) for the same reason. Multiply them and get the pool area plus the sidewalk area. But you only need the sidewalk area so you would subtract the pool area from the whole area, to get (b+6)(h+6)-bh, or A in the end.
Unfortunately, I do not know the answers to the rest of the problems. I still hope this helped though!
Answer:
x<−2
Step-by-step explanation:
Let's solve your inequality step-by-step.
6x+12<3x+6
Step 1: Subtract 3x from both sides.
6x+12−3x<3x+6−3x
3x+12<6
Step 2: Subtract 12 from both sides.
3x+12−12<6−12
3x<−6
Step 3: Divide both sides by 3.
3x/3<−6/3
x<−2
Hope this helps :)
Don't really need to post the options to know what the expression(s) should look like.
"Sum of" tells you its addition and because it's addition the order of the two terms (the 3 and the N) don't matter.
Your correct expressions are:
3 + n
or
n + 3
