Answer:
120 +10w = 75 + 15w, w=weeks, found by adding savings to rate times and unknown variable of weeks and setting equal to each other. 9 wks, $210
Step-by-step explanation:
120 +10w = 75 + 15w
120-75= - 10w+15w
45=5w
45/5=9
9 weeks
120 + 90 = 75 + 135
210= 210

x+5 = x+3
(x) (x+5) (x+3)
x3 + 8x2 + 15x
x (x+5) = x + 3
Answer:
x + (x + 3) + (x + 5)
Step-by-step explanation:
Sea x el número de latas que caben en el ancho.
Como hay 5 latas más que encajarán en la longitud, el número total de latas que encajarán en la longitud será (x + 5) latas
También caben tres latas más en la altura, la cantidad de latas que será (x + 3)
Así que ahora, el número total de latas que cabrán en la caja será;
x + (x + 3) + (x + 5)

Ashley spends ⅙ hours of a day online. Ashley spends 3/8 of that time writing a blog. How long does Ashley spend writing a blog?
Answer:
It should be 1/16
Step-by-step explanation:
The word of in a word problem means multiplication so if you multiply you get 1/16
Answer:
Step-by-step explanation:
Time spend on online = 1/6 of 24 hours
= [tex]\frac{1}{6}*24[/tex]
= 4 hours
Time spend on writing a blog = 3/8 of 4
= [tex]\frac{3}{8}*4[/tex]
= [tex]\frac{3}{2}= 1\frac{1}{2}[/tex]
= 1 hour 30 minutes
Rory is at the local mall and her favorite type of jeggings are on sale. The jeggings are now
priced at $7 per pair, tax free. She has $27 with her, but she needs to have $6 leftover to
spend on a movie theater ticket.
Which inequality represents how many pairs of jeggings Rory can buy, where / represents
the number of jeggings?
Answer:
j ≤ 3
Step-by-step explanation:
Since she has $27 with her and needs a balance if $6, the amount of money she can spend on buying the jeggings will be $27-$6 = $21
This means that she has $21 to spend on buying the jeggins
From the question, one jeggings cost $7, so the maximum number of jeggings she can buy is 21/7 = 3
So the inequality that represents this will be;
j ≤ 3
This is because she can decide to buy less than 3, but never can she buy more than 3 because of her budgetary constraints

Write the equation of the line that passes through the points (-7,9) and (-7,1). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
It is a vertical line
Step-by-step explanation:
Find the slope using rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(1 - 9) / (-7 + 7)
-8/0
= undefined
Dividing by 0 gives you an undefined number. This means that the slope is undefined, and the line is a vertical line.
The equation of the line that passes through the points (-7,9) and (-7,1) is x = -7.
The point slope formula is represented below:
y - y₁ = m(x - x₁)where
m = slope
Let's find slope
(-7, 9)(-7, 1)
m = 1 -9 / -7 - (-7)
m = -8 / 0 = Undefined slope.
The slope is an undefined slope. Therefore, the line is a vertical line and cannot be written in a slope intercept or point slope form.
The equation of the line can be written as x = c.
where
c = constant
Therefore,
x = -7
The equation is x = -7

Answer:
I think the answer is -12
Step-by-step explanation:
g(x) = x^2 + 3x - 2, If g(-2)
Plug the value for x into the equation
g(x)= -2^2+3(-2)-2

Anne works for a company that manufactures liquid dyes for clothing. She currently wants to mix up some 30%-concentrated red dye. She has 66 gallons of 21%-concentrated red dye, as well as plenty of 51%-concentrated red dye. How many gallons of the 51%-concentrated red dye will Anne need to add to the 21%-concentrated red dye to make a batch with a concentration of 30%?
Answer:
28.29 gallons
Step-by-step explanation:
Given that the available amount of 21%-concentrated red dye= 66 gallons.
Let x gallons of 51%-concentrated red dyes to be mixed with 56 gallons of 21%-concentrated red dye to get 30%-concentrated red dyes.
Total amount of the resulting mixture = 66 + x gallons.
Amount of red dyes in the mixture = (21% of 66) + (51% of x)
To get the resulting mixture as 30%-concentrated red dyes, we have
30% of (66+x) = (21% of 66) + (51% of x)
[tex]\Rightarrow 30(66+x)=21\times66+51x\\ \Rightarrow 30\times 66 +30x= 21\times66+51x\\\Rightarrow 51x-30x=66(30-21)\\\Rightarrow 21x=66\times 9\\\Rightarrow x = 28.29[/tex]
Hence, the amount of 51%-concentration red dyes to be mixed = 28.29 gallons.
Simplify.
