Given:
Per month fee = $55
One-time recital fee = $165
The equation represents the $495 total cost that Barbara paid to Dance Unlimited.
[tex]495=165+55m[/tex]
To find:
We need to find the number of month Barbara receive dance lessons from Dance Unlimited.
Solution:
We have,
[tex]495=165+55m[/tex]
Here, m is number of months. We need to isolate m.
Subtract 165 from both sides.
[tex]495-165=55m[/tex]
[tex]330=55m[/tex]
Divide both sides by 55.
[tex]\dfrac{330}{55}=m[/tex]
[tex]6=m[/tex]
The value of m is 6. So, the required number of month Barbara receive dance lessons from Dance Unlimited is 6.

Answer:
A.
Step-by-step explanation:
When you divide 4, it isolates the variable giving you your answer in the equation.
Answer: The answer is A, dividing both sides by 4 eliminates the variable.
Step-by-step explanation: We can find this out by following along with the steps in the process. Since we need to remove the coefficient from “x” to simplify the equation, you must divide both sides by 4 to keep both sides of the equal sign balanced. How this helped! :)
The length of a rectangular room is 4 feet longer than twice the width. If the room’s perimeter is 140 feet, what are the room’s dimensions?
Answer:
Width = 22ft Length = 48ft
Step-by-step explanation:
Length = 2(w) + 4
I personally first picked a random number (20) and I got 128, so I knew I had to pick a larger number.
I skipped up to 22 and this is what I did.
W = 22(2) <--(Since there are two width sides) = 44
L = 2(w) + 4
L = 2(22) + 4
L = 44 + 4 = 48
48(2) <--(Since there are two length sides) = 96
96 + 44 = 140
Hope this helps!

find the nth term of 8,17,26,35,....
Answer:
8 + (n-1)*9
Step-by-step explanation:
In the series, we can see that the difference between 2 consecutive terms is always 9, and the sequence starts at 8.
That means the nth term of the series must be 8 + (n-1)*9

Zachary is planning to send a video game to each of his two brothers. If he buys the same game for both brothers and pays $2.75 to ship each game, how much can he spend on each game without spending more than $100? Enter and solve an inequality for this situation. Let v be the cost of one video game
Given that,
He buys the same game for both brothers and pays $2.75 to ship each game, how much can he spend on each game without spending more than $100.
We need to solve the inequality for this situation.
Let he spent $x on each of the video game. ATQ,
[tex]2x+2\times 2.75\le 100\\\\2x+5.5\le 100\\\\2x\le 100-5.5\\\\2x\le 94.5\\\\x\le \$47.25[/tex]
So, he can spend less than or equal to $47.25 on each game.
Jalal notices the temperature outside at sunrise is -6 F*. An hour later the temperature is 12F*. Which expression represents the change in temperature?
A. 12 - (-6) = 6
B. -6 - (12)m = -18
C. -6 - (12) = -6
D. 12 - (-6) = 18
Answer:
A.
Step-by-step explanation:
If you take -6 and add 12, you first add 6 to make it zero, and have 6 to add after that. This gives you 6* F
Rachel bought new school supplies for herself at Target. Pencil packs were $4.75, markers were $6.80, and folders were $8.64. If she bought 7 folders, 2 pencil packs, and 3 packs of markers, how much money did she save if she had a 15% discount coupon?
Answer:
She saved $13.56
Step-by-step explanation:
$8.64 x 7 folders = $60.48
$4.75 x 2 packs of pencils = $9.50
$6.80 x 3 packs of markers = $20.40
$60.48 + $9.50 +$20.40 = $90.38
$90.38 - 15% = $76.82 (76.823)
She saved a total of $13.56 (13.557)
Answer:
Rachel saved $13.56
Step-by-step explanation:
Pencil Packs: 2 x $4.75 = $9.50
Markers: 3 x $6.80 = $20.40
Folders: 7 x $8.64 = $60.48
Add up the costs.
$90.38
Multiply $90.38 by 0.15
13.557
Round to the nearest hundredth.
$13.58

Beverly is making peanut butter-banana bread. She always doubles the amount of nuts and peanut butter chips. The total amount of chips and nuts after doubling is 4 1/2 cups. The recipe says one and a half cups of peanut butter chips, an unknown number of cups of nuts, and three very ripe bananas. Write and solve an equation to find the original amount of nuts, x, in the recipe.
Answer:
0.75 or three-fourth of a cup of nuts.
Step-by-step explanation:
Given that:
Original recipe has
1. One and half cups of peanut butter
2. Unknown number of cups of nuts, let this amount be [tex]x[/tex] cups.
3. Three very ripe bananas.
Total amount of chips and nuts after doubling = [tex]4\frac{1}{2}[/tex] cups
Before doubling, total amount of chips and nuts = [tex]4\frac{1}{2} \div 2 = 2.25[/tex]
Now, as per given question statement:
[tex]2.25=x+1.5[/tex]
Subtracting the number 1.5 from both the sides to find the value of [tex]x[/tex]:
[tex]2.25-1.5=x\\\Rightarrow x = \bold{0.75}[/tex]
Therefore, 0.75 or three-fourth of a cup of nuts is the original amount in the recipe.
Kim's softball team was playing in the championship game. When there were 4 innings left, the team was losing by a score of 17 to 6 points. In the last 4 innings, her team scored the same number of points per inning, and the other team did not score any more points. Kim's team won with the most points. Write an inequality to determine the number of points per inning, ppp, Kim's team could have scored. Write an inequality to determine the number of points per inning, ppp, Kim's team could have scor Find the minimum whole number of points per inning Kim's team could have scored.
Answer:
3
Step-by-step explanation:
Given the following :
Score when there were 4 innings left = 17 to 6
Kim's team = 6 ; opposition team = 17
Opposition didn't score any point in the last 4 innings
Kim's team scored same number of points per inning and also won with the most points
Minimum Number of points Kim's team could have scored per inning :
Let number of points scored in each of the last 4 innings = p
Since they also won eventually:
Then
4p + initial points > opposition point
4p + 6 > 17
4p > 17 - 6
4p > 11
p > 11/4
p > 2.75
Hence, the minimum number of points Kim's team could have scored per inning in the last 4 would be 3( nearest whole number)

Fatima has a bag of 492 grams of dried figs. She eats 16.4 grams each day. This can be represented by the equation y=492- 16.4x . Determine the x and y intercepts.
Answer:
x intercept
(x;y=0)
y=492-16.4x
0=492-16.4x
-492=-16.4x /÷(-16.4)
30=x
(30;0)
y intercept
(x=0;y)
y=492-0
y=492
(0,492)

One gram of protein contains 4 calories. One gram of fat contains 9 calories. A snack has 60 calories from p grams of protein and f grams of fat. The equation 4p + 9f = 60 represents the relationship between these quantities. If there are 6 grams of fat in the snack, how many grams of protein are there? Show your reasoning.
Answer:
1.5 grams of protein.
Step-by-step explanation:
The equation that represents the relationship between protein and fat is as follows :
4p + 9f = 60 ....(1)
We need to find the grams of protein are there if there are 6 grams of fat in the snack.
Put f = 6 in the above equation (1).
4p + 9(6)= 60
4p + 54 = 60
Subtract 54 to the both sides,
4p + 54-54 = 60-54
4p = 6
⇒ p = 1.5 grams
It means the snack contains 1.5 grams of protein.
