Step-by-step explanation:

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

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

Answer:

yes, no, yes, no

Step-by-step explanation:

the first two are correct, try an example for 2 and 3

b = a - 5 yes

if a = 5 and b = 0

5 - 5 = 0

a = b - 5 no

if a = 5 and b = 0

5 = 0 - 5 which is not true 5 doesnt equal -5

Answer:

300 + 250 = 550

550/50 = 11

$11 per costume

The selling price of each costume will be equal to $11 per costume.

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

300 + 250 = 550

550/50 = $11

$11 per costume.

__

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.

Answer:

It takes Tyler 65 minutes to run 10 miles.

Step-by-step explanation:

First you have to figure out what Tyler's mph is, so you divide 8  2/3 by 4/3=6.5. Then you multiply by 10 get how long it takes him to run 10 miles.

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

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:

The second one is correct

Step-by-step explanation:

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
