Answer:
a6
Step-by-step explanation:
Match each expression with the equivalent expression.
2(6x + 6)
16x - 8
3(x - 2)
3(4x + 4)
2x + 6
4(x + 3)
Options for ALL:
4x + 12
2(x + 3)
8(2x - 1)
12x + 12
3x - 6
Answer: distributing
2(6x + 6) is 12x + 12
16x - 8 is 8(2x - 1)
3(x - 2) is 3x - 6
3(4x + 4) is 12x + 12
2x + 6 is 2(x + 3)
4(x + 3) is 12x + 12
Step-by-step explanation:
Distribute the number in front of the parenthesis to the numbers inside the parenthesis .
for example: 3(x-2)
3 times x = 3x
3 times -2= -6
answer: 3x - 6
Simplify the expression: 4x+2+12x+17
4x + 2 + 12x + 17
= 4x + 12x + 2 + 17
= 16x + 19
Answer:
[tex]4x + 2 + 12x + 17 \\ = (4 + 12)x + (2 + 17) \\ = 16x + 19[/tex]
Write inequalities to represent the situations below.
The vehicle's fuel efficiency is no less than 45 miles per gallon.
Use f to represent the vehicle's fuel efficiency (in miles per gallon).
Martina exercises at least 45 minutes per day.
Use t to represent Martina's amount of exercise (in minutes per day).
Answer:
[tex]f \ge 45[/tex]
[tex]t \ge 45[/tex]
Step-by-step explanation:
Solving (a): No less than 45
In inequalities, no less than means [tex]\ge[/tex]
So, the statement can be represented as:
[tex]f \ge 45[/tex]
Solving (b): At least 45
In inequalities, at least means [tex]\ge[/tex]
So, the statement can be represented as:
[tex]t \ge 45[/tex]

Larry’s pet store made $30 before a pipe burst and he had to close early to get it fixed. He realized that he lost Three-fourths of a dollar each hour that the store was closed. If the expression that models this situation is 30 Negative three-fourths x, what is Larry’s profit if the store was closed for 8 hours?
Answer:
$24
Step-by-step explanation:
You will plug in 8 for x :)
30 - (3/4)x
Since he loses 3/4 a dollar for every hour he can't work, (3/4) x 8 = 6. He will lose 6 dollars from this. 30 - 6 = 24.
His final profit is 24.

Answer:
8 and 64
Step-by-step explanation:
4/1 = 4
8/2 = 4
32/8 = 4
64/16 = 4
Answer:
1:4
2:8
8:32
16:64
Step-by-step explanation:
The constant of proportionality is 1:4. Whatever number is on the right has to be 4 times greater than the number on the left for it to be proportional. I divided 32 by 4 to get 8 on the first one, and I multiplied 16 by 4 on the second one to get 64.

Help I guess? sorry I'm asking a lot of questions today
Answer:
63 houses have been sold this year.
Step-by-step explanation:
There are 81 houses in the community. If 7/9 are sold this year, then all you have to do is multiplication.
In this case, you would multiply 81 by 7/9 to get your answer.
81/1 x 7/9:
Cancel out the 9 and the 81. Then the denominator will be 1 x 1 and the numerator would be 7 x 9. It would be 63 (7x9=63) over 1 (1x1=1) which is just 63. Make sure to include units.

Hey there!
“Put the fraction in least to greatest 1/5, 5/5, and 4/5”
Given numbers:
• 1/5
• 5/5
• 4/5
• We can make this EASIER to solve by converting your given fraction(s) in decimals (and maybe percentages)
• 1/5 = 0.2 = 20%
• 5/5 = 1 = 100%
• 4/5 = 0.80 = 80%
• So now that we got that out of the way, we have your answer
Answer: 1/5 , 4/5 , 5/5 ☑️

Step 4: Write your answer sentence
Answer:
Answer:
Vicki takes 12 minutes.
Step-by-step explanation:
Call the time that Dennis takes to read; D
The time that Vicki takes to read is; V
As per the question;
Dennis takes 3 times as long as Vicki takes to read a paper, hence the equation formed is;
D = 3V
