Sally will earn $30 for every 5 hours that she babysits. Which of the following equations can be used to represent the proportional relationship?
a
y = 5x + 6
b
y = 6x
c
y = 1/6x +30
d
y = 6x +5
Answer:
It depends on what they are asking. If they are asking how much money she gets paid by the hour, then it is b.
Step-by-step explanation:
Answer:
B. [tex]y = 6x[/tex]
Step-by-step explanation:
Step 1: Divide 30 by 5
[tex]\frac{30}{5}\\\\=30 \div 5\\\\= 6[/tex]
Therefore, the answer closest to that is B. y = 6x.
A store is having a 20% off sale on all merchandise. If Mai buys one item and saves $13, what was the original price of her purchase? Explain or show your reasoning.
Answer:
Step-by-step explanation:
If a store is having a 20% off sale
By buying an item you save 20% of the price
If Mai saves $13 on an item she is also saving 20%
$13 = 20% of the price
$65 = 100% of the original price
$65 is your answer!
Answer:
The Answer is $65! The orignal price of the item $65 because if you save $13 on a 20% off sale it would make the orignal price $65

16). The sales tax rate in Jan’s town is 7.5%. If she buys 3 lamps for $23.59 each and
a sofa for $769.99, how much sales tax does she owe?
A. $58.85
B. $63.06
C. $67.26
D. $71.46
Please answer right
Answer:
B 63.06
Step-by-step explanation:
23.59 x 3 = 70.77
7.5% x 70.77 = 5.31
7.5% x 769.99 = 57.75
57.75 + 5.31 = 63.06
The rate to rent a truck for a day is a one-time fee of $35 and $0.20 per mile.
Write an expression to model this situation.
How far could you travel if you drove 40 miles?
Answer: y= $0.20x + $35 or y= $0.20 * 40 + $35 (Depending on what you mean)
Step-by-step explanation:
The equation for these types of problems is y = mx + b.
M would be $0.20, because that is the value that can repeat, based on x. For example, if this was 2 dollars per mile (m) for 3 miles, (x) than y, the total amount for mx would amount to 6 dollars.
Now, 35$ Is a one time fee (b), so you can add that separately to $0.20x.
If you plug everything in, you would get y= $0.20x + $35.
I am not very sure about what you mean by “ How far you could you travel if you drove 40 miles”, but if you mean how much would you pay to drive 40 miles, I can help there.
Now that we know x would be the amount of miles, we can plug that into the equation.
You would get y= $0.20 * 40 + $35.

A group of adults and students buy tickets for a dance performance.
Each ticket costs $4.65.
The total cost of the tickets for the group is $93.00.
There are exactly 3 adults in the group
What is the number of students in the group?
The number of students in the group are 17.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that a group of adults and students buy tickets for a dance performance.
The cost of each ticket is $4.65.
The total cost of the tickets for the group is $93.00.
There are exactly 3 adults in the group
We need to find the number of students in the group.
Let x be the number of students.
3(4.65)+4.65x=93
13.95+4.65x=93
Subtract 13.95 on both sides
4.65x=93-13.95
4.65x=79.05
Divide both sides by 4.65
x=17
Hence, the number of students in the group are 17.

Solve the inequality.
3≤7+g
Answer:
g-4
Step-by-step explanation:
first subtract 7 from both sides
then you will get -4[tex]\leq[/tex]g
which is the same as g[tex]\geq[/tex]-4
you just have to switch them
The solution to the equation for inequality 3≤7+g is g ≥ -4. Equations and inequalities are both mathematical sentences that are formed by connecting two expressions.
How to solve the inequality ?Equations and inequalities are both mathematical sentences that are formed by connecting two expressions. The symbol = indicates that the two expressions in an equation are deemed equal. In contrast, in an inequality, the two expressions are not always equal, as indicated by the symbols: >,, or.
You test the end point by plugging it into the related equation. The inequality is then tested to see if it is correct by substituting any other solution to see if it is one of the solutions.
Rearrange the equation by subtracting what is to the right of the less equal sign from both sides of the inequality :
3-(7+g)≤0
Pull out like factors :
-4 - g = -1 • (g + 4)
Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
g+4 ≥ 0
Subtract 4 from both sides
g ≥ -4
The solution to the equation for inequality is g ≥ -4.
