Sushil is 6 years older than Brian. Caroline is 5 years younger than Brian. If the total of their ages is 64, how old is the youngest of them
Answer:
16 years old
Step-by-step explanation:
Let's use the letters s, b, and c for Sushil, Brian, and Caroline's ages. Sushil is the oldest, followed by Brian, and then Caroline, the youngest. From the problem description, we can set up three equations:
s = b + 6 (Sushil is 6 years older than Brian)
c = b - 5 (Caroline is 5 years younger than Brian)
s + b + c = 64 (The total of their ages is 64)
Since s and c are already in terms of b, we can substitute them into the last equation and solve to find Brian's age:
(b + 6) + b + (b - 5) = 64
3b + 1 = 64
3b = 63
b = 21
Now that we know Brian's age, we can simply subtract 5 to find Caroline's:
c = b - 5 = 21 - 5 = 16 years old.

Which is a graph of y=-3x + 2?
Answer:
Step-by-step explanation:
it's this one
2. Was your plan in part B an example of direct variation (the plan depended only on the time spent talking) or a partial variation? (the plan depended on the time spent talking and an initial cost). 3. Which Plan best for you? Was this the same as your hypothesis? 4. Which plan had the highest rate of change? Which plan has the lowest slope? 5. Using your graph, which plan would be best if you talked for 200 minutes? 6. When is the Rogers My5 plan better than the Telus prepaid plan? 7. Which plans are an example of direct variation? 8. Come up with at least 3 other things that need to be considered when choosing your cell phone plan (aside from cost per minute talking), and explain why these are important to you.
9514 1404 393
Answer:
2. not direct variation; is "partial variation"
3. Public Mobile
4. highest: Telus (prepaid); lowest: Public Mobile
5. Public Mobile
6. > 200 minutes
7. Plans 1, 2, 3 (with b=0) are direct variation
Step-by-step explanation:
Reference https://brainly.com/question/20889835 for more information
__
2. The "Part B" plan chosen has a y-intercept (b) of 24, so is not direct variation. Here, that qualifies it as "partial variation."
__
3. The lowest rate by far for 600 minutes is offered by Public Mobile (plan 6). That is the same as our hypothesis.
__
4. The highest rate of change (m) is that for Plan 3, Telus (prepaid). Its cost of $0.35 per minute is higher than that for any other plan.
The plan with the lowest slope (m) is Plan 6, Public Mobile, which has zero slope.
__
5. A graph of all the plans is shown in the attachment. For any time over 140 minutes, Plan 6, Public Mobile, is the lowest cost.
__
6. On the graph, the purple line (Rodgers MY5) plan becomes lower cost for more than 200 minutes. Below that time, the green line (Telus prepaid) is lower cost.
__
7. Plans 1, 2, 3 have no cost for zero minutes, so they are all examples of direct variation.
__
8. This is a personal question, so cannot be answered for you. Some of the things usually considered (in no particular order) are ...

two years ago a man was six times as old as his daughter. In 18 years he will be twice as old as her, determine their present ages
Step-by-step explanation:
Let m = man's age right now
d = daughter's age right now
m-2 = 6(d-2) => m = 6d -12 +2 = 6d-10
m+18 = 2(d+18) => m = 2d+36-18 = 2d+18
6d-10 = 2d+18
4d = 28
d = 7
m = 32

The area of the triangle is 30 sqaure inches.
Answer:
I believe the area would be 30 inches. All you do is 12 times 5 which is 60 and then you divide 60 by two because it's a triangle, and you get 30. hope this helped.

[tex] \frac{42}{ \sqrt{28} } + \frac{60}{45} - 2 \sqrt{20} + 2\sqrt{175} [/tex]
Answer:
4/3−4√5+13√7
Step-by-step explanation:
So for whatever reason we don't like it when the radical is in the denominator so we're going to do a process called rationalization and get rid of it. We do this by multiplying both the numerator and denominator by the radical
So for the first part we multiply the numerator and denominator by [tex]\sqrt{28}[/tex] which gives us [tex]\frac{42\sqrt{28} }{28}[/tex] we can then factor the 28 into sqrt(7,2,2) which simplifies to [tex]42*2\sqrt{7}[/tex]/28 So then we can simplify this and get [tex]3\sqrt{7}[/tex] We then can simplify the rest of these radicals and get [tex]2\sqrt{20}=2\sqrt{2*2*5}=4\sqrt{5}[/tex] and [tex]2\sqrt{175}= 2\sqrt{5*5*7}=2*5\sqrt{7}[/tex] This means that so far we have the following:[tex]3\sqrt{7}+ \frac{60}{45}-4\sqrt{5} +10\sqrt{7}[/tex] We can add the like terms and simplify the fraction and get 4/3−4√5+13√7
Aida bought a costume box containing 50 costumes for $300. She sold all of the costumes and made a $250 profit. She sold all of the costumes for the same price. Use the equation 50c−300=250, where c is the selling price of each costume. What was the selling price of one costume in dollars?
HURRYY WILL GIVE BRAINLIEST TO THE FIRST PERSON THAT ANSWERS !!!!!
Answer:
300 + 250 = 550
550/50 = 11
$11 per costume
The selling price of each costume will be equal to $11 per costume.
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
As per the given information in the question,
Total number of costumes = 50
Total profit made by Aida = $250

A movie theater sells popcorn and fountain drinks. Brett buys 1 popcorn bucket and 3 fountain drinks for his family, and pays $9.50. Sarah buys 3 popcorn buckets and 4 fountain drinks for her family, and pays a total of $19.75. If p represents the number of popcorn buckets and d represents the number of drinks.
Answer:
Step-by-step explanation:
p + 3d = 9.50
3p + 4d = 19.75
-3p - 9d = -28.50
3p + 4d = 19.75
-5d = -8.25
d= $1.65 drinks
p + 3(1.65) = 9.50
p + 4.95 = 9.50
p = $4.55 popcorn

riley can dribble a basketball 50 times in 1/2 minute with her right hand and 30 times in 1/2 minute with her left hand. what is the ratio of her right hand to her left hand dribbling rate?
Answer:
5:3.
Step-by-step explanation:
Riley can dribble a basketball 50 times in 1/2 minute with her right hand and 30 times in 1/2 minute with her left hand.
Rate of her right hand is : [tex]\dfrac{50}{(1/2)}=100\ \text{per minute}[/tex]
Rate of her left hand is : [tex]\dfrac{30}{(1/2)}=60\ \text{per minute}[/tex]
Ratio of her right hand to her left hand dribbling rate : [tex]\dfrac{100}{60}=\dfrac{5}{3}[/tex]
So, the required ratio is 5:3.

Answer:
$120.36
Step-by-step explanation:
The computation of the amount that should be pay to his credit card is as follows;
= Purchase of groceries + gas charges + video game
= $25.87 + $42.25 + $52.24
= $120.36
He has to pay the above amount to his credit card company to avoid the interest charges on these purchases

Answer:
[tex]10\sqrt{3}[/tex]
Step-by-step explanation:
Trigonometric Ratios
This problem will be solved by the use of a trigonometric ratio called sine because it relates the opposite side of a given angle with the hypotenuse of the triangle.
Selecting the angle of 60° in triangle ABD:
Sine Ratio
[tex]\displaystyle \sin 60^\circ=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]
[tex]\displaystyle \sin 60^\circ=\frac{BD}{20}[/tex]
Solving for BD:
[tex]\displaystyle BD=20\sin 60^\circ[/tex]
Since

[tex]\displaystyle BD=20\frac{\sqrt{3}}{2}[/tex]

I need help graphing -8x-y=8
Answer:
y = -8x - 8
Step-by-step explanation:
Add -8x on both sides to get -y = 8x + 8 and flip the y sign on the left to get your slope function which is y = - 8x - 8.
To graph the function, you would need to put (0, -8) as your y-intercept, and each unit will go down 8 units when you add 1.
Answer:
y=8x+8
Step-by-step explanation:
Just rewrite the problem so it's in y=mx+b format then it's easy to graph
Remember the y intercept is 8 because when x=0 y=8 and the slope is 8 so go up 8 and right 1
