9c +4 = -23
subtract 4 from each side
9c = -27
divide both sides by 9
c = -27 /9 = -3
c = -3

Trevon, Leah, and Beth are playing a computer game. Trevon scores -8. Beth’s score was 3/4 of trevons score, and Leah’s score was 1/4 of Beth’s score. What was Leah’s score
Answer:
[tex]-1.5[/tex]
Step-by-step explanation:
We have been given that Beth's score is 3/4 of Trevon's score.
[tex]\text{Beth's score}=-8\times \frac{3}{4}[/tex]
[tex]\text{Beth's score}=-2*3[/tex]
[tex]\text{Beth's score}=-6[/tex]
We are also told that Leah’s score was 1/4 of Beth’s score.
[tex]\text{Leah's score}=-6\times \frac{1}{4}[/tex]
[tex]\text{Leah's score}=-\frac{3}{2}[/tex]
[tex]\text{Leah's score}=-1.5[/tex]
Therefore, Leah score was [tex]-1.5[/tex].

Write the rule for the pattern. 128, 64, 32, 16, . . .
Each term in the sequence is obtained by dividing the previous term by 2. Therefore, the rule for the pattern in the given sequence is to halve each term to obtain the next term.
The pattern in the given sequence is a halving pattern.
The rule for the pattern:
1. The first term in the sequence is 128.
2. Each subsequent term is obtained by dividing the previous term by 2.
Let's see how this rule applies to the given sequence:
128 / 2 = 64
64 / 2 = 32
32 / 2 = 16
Every term in the series is created by dividing the one before it by two. The rule for the pattern in the above sequence is to divide each phrase in half to produce the following term.

In the expression 1/4 divided by 5/7, which of the following is the divisor
1/4
4
5/7
7
Answer:
[tex]\frac{5}{7}[/tex]
Step-by-step explanation:
Given expression 1/4 divided by 5/7
For any division [tex]\frac{a}{b}[/tex]
'a' is the dividend and 'b' is the divisor
Denominator is the divisor
[tex]\frac{\frac{1}{4} }{\frac{5}{7}}[/tex]
Here, the denominator is 5/7
So the divisor is [tex]\frac{5}{7}[/tex]

Naomi has earned$54 mowing lawns the past two days. She worked 2 1/2 hours yesterday and 4 1/4 hours today. If Naomi is paid the same ammount every hour she works, how much does she earn per hour? (show your work)
Answer:
Naomi earns $8 per hour.
Step-by-step explanation:
Naomi has earned$54 mowing lawns the past two days.
She worked 2.5 hours yesterday and 4.25 hours today.
Suppose she earns x dollars per hour and is paid the same amount every hour she works.
We get the equation;
[tex]2.5x+4.25x=54[/tex]
[tex]6.75x=54[/tex]
x = 8
Hence, she gets $8 per hour.

Mr. Rijo bought 49 bags of soil one week and 28 bags of soil the next week. Which expression correctly applies the distributive property to show equivalent expressions for the number of bags of soil he bought?
49 + 28 = 4(7 + 7)
49 + 28 = (7)(7) + (14)(2)
49 + 28 = (7)(14) + (7)(7)

The Nash family spent a total of $240 on a hotel room for 3 nights. Which equation can be used to find c, the average cost per night for the hotel room?
Answer:
240 divided by 3 = c
Step-by-step explanation:
Tricky...it is $240 for all 3 nights....not $240 per night. So it is division NOT multiplication.
richard bought rolls for a bbq he bought 4 1/4 dozen wheat rolls and 5 2/3 snowflake rolls if 4 1/3 were eaten at the bbq how many dozen rolls does richard have left
Answer: Richard has 5 7/12 rolls left.
Step-by-step explanation:
Hi to answer this question, first, we have to sum the amount of rolls Richard bought for the bbq:
4 1/4 + 5 2/3 = 4 3/12 + 5 8/12 = 9 11/12
Finally we have to subtract the amount of rolls eaten at the bbq to the previous number.
9 11/12 - 4 1/3 = 9 11/12 - 4 4/12= 5 7/12
So, Richard has 5 7/12 rolls left.

What is the length of a segment in the complex plane with endpoints at 4 + 2i and 7 – 2i?
Answer:
5
Step-by-step explanation:
A little trick: the imaginary part ([tex]i[/tex]) in the coordinates of complex numbers act same as the y-coordinate in a rectangular plane.
So we want the distance between the coordinate points (4,2) and (7,-2).
How do we get the distance between 2 points? We use the distance formula.
Distance Formula = [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
Where [tex](x_1,y_1)=(4,2)[/tex] and [tex](x_2,y_2)=(7,-2)[/tex]
Let's solve for distance:
[tex]\sqrt{(-2-2)^2+(7-4)^2}\\ =\sqrt{(-4)^2+(3)^2} \\=\sqrt{16+9} \\=\sqrt{25} \\=5[/tex]
Hence, the length of the segment in the complex plane with endpoints at 4 + 2i and 7 – 2i is 5.
