Avery needs a total of $12.75 in quarters at
the local laundromat. She has already saved
$3.25. Which equation and solution process
can be used to determine q, the number of
additional quarters Avery needs to wash her
laundry?
A) 12.75 = 5 + 3.25
Sub
tract 3.25 from both sides and multiply
the difference by 25.
B)3.25 -0.259 = 12.75
Subtract 3.25 from both sides and divide
the difference by -0.25.
I
C)12.75 = 0.259 + 3.25
Subtract 3.25 from both sides and divide
the difference by 0.25.
D) 259 + 3.25 = 12.75.
Subtract 3.25 from both sides and divide
the difference by 25.
Answer:
C
Step-by-step explanation:
12.75=3.25+0.25q
9.50=0.25q
38=q.

Answer:
if its up and down, I'm pretty sure it's D.
yes or no
if yes pls tell me what the unit rate is
I WILL MARK U BRAINLIEST
(attachment)
Answer:
Yes, and the unit rate is 1:48
Step-by-step explanation:
If you start by dividing 204 by 4.25, you will see you get an answer of 48. Now if you move on to the next row, and divide 252 by 5.25, you also get 48. If you do the same with the last two rows, you get 48 for both. This shows that the unit rate is 1:48.

The height of an object thrown straight up from a height 5 feet above the ground is given by the equation h(t) =-16t^2 +42t +5, where is the time in seconds after the object is thrown. Find the average speed of the object from 1.5 to 2.25 seconds.
Answer:
The average speed of the object is 18.67 ft/s.
Step-by-step explanation:
Given;
height function, f(t) = -16t² + 42t + 5
The average speed is given by ;
[tex]v = \frac{dx}{dt} \\\\h(t) = -16t^2+42t+5\\\\h(1.5)= -16(1.5)^2 + 42(1.5)+5 = 32 \ ft\\\\[/tex]
from 1.5 s to 2.25 s = 0.75 s,
[tex]h(0.75)= -16(0.75)^2 + 42(0.75)+5 = 27.5 \ ft[/tex]
[tex]h(2.25)= 27.5 +(-16(2.25)^2 + 42(2.25)+5) \\\\h(2.25) = 27.5 + 18.5 = 46 \ ft[/tex]
The average speed is given by ;
[tex]v = \frac{h(2.25) - h(1.5)}{2.25-1.5}\\\\v = \frac{46-32}{0.75}\\\\v = 18.67 \ ft/s[/tex]
Therefore, the average speed of the object is 18.67 ft/s.

Answer:
b. SSS
Step-by-step explanation:
The diagram provided shows that:
DE is congruent to DG,
EF is congruent to FG, and
DF is congruent to DF
Thus, all three sides of ∆DEF is congruent to all corresponding sides of ∆DFG. Therefore, by the Side-Side-Side Congruence Theorem, ΔDEF ≅ΔDFG.
Help !! (x + 2y = 6.)
Answer:
what do you exactly want me to do? rewrite the equation or solve it?
Step-by-step explanation:
Answer:
x=−2y+6
y=−12x+3
Step-by-step explanation:
Let's solve for x.
x+2y=6
Step 1: Add -2y to both sides.
x+2y+−2y=6+−2y
x=−2y+6
Let's solve for y.
x+2y=6
Step 1: Add -x to both sides.
x+2y+−x=6+−x
2y=−x+6
Step 2: Divide both sides by 2.
2y/2=−x+6/2
y=−12x+3
For what value of k does kx + 7y = 10 have a slope of 3?
Answer:
k = -21
Step-by-step explanation:
Slope y-intercept form : y = mx +c
kx + 7y = 10
7y = -kx + 10
y = [tex]\frac{-k}{7}x+\frac{10}{7}[/tex]
[tex]\frac{-k}{7}=3\\\\ -k = 3*7\\\\ -k = 21\\\\ k = -21[/tex]

_________________________________
Hint :
[tex]slope = The \: \: coefficient \: \: of \: \: x \: \: in \: \: the \: \: slope-intercept \: \: form \\ [/tex]
_________________________________
Thus we need to find the slope-intercept form of the line which must be like this :
[tex]y = ax + b[/tex]
Let's do it...[tex]7y + kx = 10[/tex]
Subtract sides kx
[tex]7y + kx - kx = 10 - kx[/tex]
[tex]7y = 10 - kx[/tex]
[tex] 7y = - kx + 10[/tex]
Divide sides by 7
[tex] \frac{7y}{7} = \frac{ - kx + 10}{7} \\ [/tex]
[tex]y = \frac{ - kx}{7} + \frac{10}{7} \\ [/tex]
[tex]y = - \frac{k}{7} x + \frac{10}{7} \\ [/tex]
This is the slope-intercept form .
[tex]The \: \: coefficient \: \: of \: \: x = - \frac{k}{7} \\ [/tex]
The slope is 3 ,
Thus :
[tex] - \frac{k}{7} = 3 \\ [/tex]
Multiply sides by 7
[tex]7 \times ( - \frac{k}{7}) = 7 \times 3 \\ [/tex]
[tex] - k = 21[/tex]
Multiply sides by - 1
[tex] ( - 1) \times ( - k) = ( - 1) \times (21)[/tex]
[tex]k = - 21[/tex]

Alexis had 98 trading cards last Saturday.
(o
She gave a dozen to her little brother but her big brother gave her a pair.
Alexis traded 9 more cards for 4 new ones that were more valuable.
She then traded another half dozen for 1 that she had been hoping to find.
Alexis wants to get a card album for her birthday so she can organize all her cards.
Yesterday she was running home with all of her cards in her bag. She dropped two of her
cards along the way because the bag was not zipped.
How many cards did she have when she got home?
What is the first thing that you would do to solve this problem?

A doctor prescribe 125 miligrams of a therapeutic drug that decays by about 10% each hour. Write an exponentia lmodel representing the amount A in milligrams of the drug remainng in the patient's system after t hours.
Answer:
[tex]C(t)=125\cdot 0.9^t[/tex]
Step-by-step explanation:
Exponential Decay Function
The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function is expressed as:
[tex]C(t)=C_o\cdot(1-r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The doctor prescribed 125 milligrams of a therapeutic drug. It decays by 10% each hour. The initial value is Co=125 and the decay rate is r=0.1 per hour. Substituting into the function:
[tex]C(t)=125\cdot(1-0.1)^t[/tex]
Operating:
[tex]\mathbf{C(t)=125\cdot 0.9^t}[/tex]
Where t is expressed in hours.

A supermarket sells orange juice in three sizes. The 32 fl oz container costs $1.99,the 64 fl oz container costs $3.69, and the 96 fl oz container costs $5.85. Which size orange juice has the lowest price per fluid ounce? Explain!
Answer:
64 fl oz
Step-by-step explanation:
To find the best price you take the cost and divide it by the number of fluid ounces ($1.99/32). For the 32 oz it costs .062, for the 64 oz it costs .057, and for the 96 oz it costs .060 (these are all approximate number btw). Therefore, since 64 oz has the lowest number it has the lowest price per fluid oz.
Select the statements that is SOMETIMES TRUE.
a. A parallelogram has congruent diagonals.
b. A rhombus is a parallelogram.
c. A parallelogram is a square.
d. A rectangle is a square.
Answer:
A and B
Step-by-step explanation:
Here, we want to select the statements that are sometimes true
The correct answers are that;
1. A parallelogram has congruent diagonals
This is in the case of a rectangle
Whenever we have the diagonals of a parallelogram equal, then what we have is a rhombus
b. A rhombus is a parallelogram
In this case, we have that a rhombus is a kind of parallelogram with all four sides equal and the diagonal meet at 90 degrees
Kareem is a software salesman. His base salary is $2200, and he makes an additional $60 for every copy of Math is Fun he sells.
Let P represent his total pay (in dollars), and let N represent the number of copies of Math is Fun he sells. Write an equation relating P to N. Then use this
equation to find his total pay if he sells 26 copies of Math is Fun.
Answer:
Step-by-step explanation:
a. p=2200+60n
b. p=2200+60(26)
p=2200 plus 1560
p=3760
The equation that should be related P to N should be considered as the 2200+60n.
And, the total pay when he sells 26 copies of Math is Fun should be 3760.
Calculation of the equation & the total pay:Since
His base salary is $2200, and he makes an additional $60 for every copy of Math is Fun he sells.
Here P means the total pay
So, here the equation be p=2200+60n
Now the total pay be
p=2200+60(26)
= 2,200 + 1,560
= 3,760
hence, The equation that should be related P to N should be considered as the 2200+60n.
And, the total pay when he sells 26 copies of Math is Fun should be 3760.
