cindy bought a new jacket. Jill bought a jacket that costs 3 times as much as Cindy. Altogether their jackets cost 300$. What equation can be used to represent the problem and how much was each of their jackets?

Answers

Answer:

x + 3x = $400

the jacket cost price of Cindy nd Jill is $100 and $300 respectively

Step-by-step explanation:

The computation is shown below:

Here we assume the cindy be x

So the Jill be 3x

Now the equation is

x + 3x = $400

4x = $400

x = $100

So the Cindy jacket cost is $100

And, the Jill jacket cost would be

= 3x

= 3(100)

= $300

Hence, the jacket cost price of Cindy nd Jill is $100 and $300 respectively

The area of a TV screen is 576 square
inches. If the width of the screen is
32 in., what is the height?

Answers

Answer:

18 inches, assuming that the height is the length of the TV screen.

Step-by-step explanation:

First off, the shape of a TV screen is a rectangle.

To get the area of a rectangle, the equation would be:

H * W = A

where H = height, W = Width, and A = area.

If we pluck in the values given in the question, we get:

H * 32 = 576

To find out H, we have to get rid of the 32.

To do that, we divide both sides by 32.

Therefore, the equation is now:

H = 18.

Thus, the height of the TV screen is 18 inches.

Answer: h = 18 inches

Help! Show work! Triangle PQR ≅ Triangle XYZ
PQ = 3a + 4 and XY = 5a – 12. Find a and PQ.

Answers

Answer:

a= 8 and PQ= 28

Step-by-step explanation:

since triangle XYZ and triangle PQR are congruent, we will write the equation like this:

PQ=XY

3a+4= 5a—12

3a—5a= —12—4

—2a= —16

a= 8

SUBSTITUTE THE VALUE OF A IN THE EQUATION TO GET THE VALUE OF PQ

PQ= 3a+4

PQ= 3(8)+4

PQ= 24+4

PQ= 28

6d + 7 = 61 what does d equal?

Answers

Answer:

i would reword this to 6x+7=61

Step-by-step explanation:

So.  

move the 7 to the right side of the equation but as an opposite number so in this case its gonna be a negative

61-7=54

then you divide the number and get your missing numbers

54/6=9

d=9

plug it in

6(9)+7=61

D is equivalent to 9

61 minus 7 is 54 what is 54 divided by 6?? 9 so the answer is 9

The product of two consecutive integers is 72. Write a quadratic equation to find the integers, and then solve it.

Answers

Answer:

9 x 8

Step-by-step explanation:

Answer:

ok so basically what you do is since you know they are consecutive numbers, one is x and the other is x+1. Now when you multiply x and x+1 you get 72 , so this basically turns into a quadratic where x(x+1)=72. Thus,X^2+x=72. subtract 72 from both sides- x^2+x-72=0. Then you can solve for x using the quadratic formula or some other way and you get x to be 8 or -9. OH WAIT THERE IS ANOTHER SOLUTION IT IS -9 AND -8. . Anyway yea hoped this helped.

Vinnie is searching online for airline tickets. Two weeks ago, the cost to fly from Denver to Hartford
was $200. Now the cost is $310. What is the percent increase? What would be the percent increase il
the airline charges an additional $50 baggage fee with the new ticket price?
The percent increase of the airline ticket is 11%.
annandad

Answers

Answer:

The ticket increased 57% of its original price

The baggage price was 44.5 increased 0.11% and then became 50

Step-by-step explanation:

So if the amount was 200 and now is 350, we should use division.

200 ÷ 350 = 0.5714285714285714 which you can round to 0.57 or as many digits as the question asked for. In thise case I will use 0.57

0.57 converted to percentage is 57%

About the second question

now you know the amount after increase and the percentage. So all you have to do is reverse.

11% = 0.11

0.11  ✕ 50 = 5.5    

this means the price increased 5.5

50 - 5.5 = 44.5

Answer: 6 snack bags

Step-by-step explanation:

In rder to know mnay bags destiny ca make, we need a number is a factor of 18 and 12, so that the 18 chocolate candy bars and the 12 cookies can be divided up evenly.

So, if there were 2 bags, thre would be 18÷2=9 chocolate candy bars and 12÷2=6 cookies in a bag. This creates identical snack bags, but isn't the greatest number of bags!

To find the greatest snack bag, we want to find the greatest common factor of 18 and 12

To do so, let's find factors of 18 ans 12

18: 1, 2, 3, 6, 9, 18

12: 1, 2, 3, 4, 6, 12

The greatest common factor of 18 and 12 is 6. in math notation this looks like:

gcf (18, 12) = 6

Factor completely 5x2 − 5x − 100.

Answers

Answer:

5(x - 5)(x + 4)

Step-by-step explanation:

Given

5x² - 5x - 100 ← factor out 5 from each term

= 5(x² - x - 20) ← factor the quadratic

Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (- 1)

The factors are - 5 and + 4, since

- 5 × 4 = - 20 and - 5 + 4 = - 1, then

x² - x - 20 = (x - 5)(x + 4) and

5x² - 5x - 100 = 5(x - 5)(x + 4)

The measure of angle 1 is 64 degrees

First you need to find the measure of angle 3

To find the measure of angle three subtract 116 from 180 because angle 3 is on a straight line which is equivalent to 180 degrees. Angle 3 is 64 degrees.

Then you add 64 and 52 then subtract that sum by 180 because the measure of a triangle equals 180 degrees.

64+52=116
180-116=64

Therefore angle 1 is 64 degrees

Hope this helps :)

Answer:

I solved it for u!

Hope it helps

Step-by-step explanation:

Another way, it an isosceles triangle so the base will be same, so angle 3 and angle 1 will be same after u find angle 3, then angle 1 will be equal to it

So here angle 3 = 64°

So angle 1= 64°
