Answers

Answer:

x= 2 or x= -3

Step-by-step explanation:

Bring the equations together using a common denominator (x-5) (x+7)

x-29/(x-5) (x+7)= 1

Multiply both sides by (x-5) (x+7)

x- 29= (x-5) (x+7)

x- 29= (x-5) (x+7)= x^2 + 2x - 35

-x^2 - x + 6 = 0

-(x-2)(x+3)= 0

Multiply both sides by -1

(x-2)(x+3)= 0

Split it into two equations

x-2= 0 or x+3= 0

x= 2 or x= -3

T-shirts that usually sell for $28.99 are on sale
for $17.39. What percent off are they?

Answers

Answer: i think it is  46.38 %

Step-by-step explanation: add both numbers ( decimals) and just put the percentage. hope this will help u stay safe :)

Answer:

38.3%

Step-by-step explanation:

We have two equations to find the answer.

1. Discount = OG Price * Discount by 100%

2. Final Price = OG Price - Discount

So fill in the first equation :

Discount = 28.99 * 38.3/100

Discount = 28.99 * 0.38

Saved = $11.10

Now for the second equation :

Final Price = 28.99 - 11.10317

Final Price = $17.89

Therefore the discount is 38.3%

Answer:

Both C and D are similar

Step-by-step explanation:

The are similar because each of the sides are proportional to each other. On letter C the scale factor of each side is 1.2. To get from the first triangle to the second, they multiplied each side by 1.2 and ended up with a slightly larger triangle. The same thing happens on the second one except for it is slightly smaller with a scale factor of 1/2.

Them sum of two numbers is 17. One number is 3 less than 2/3 of the numbers. What is the lesser number?

Answers

Answer:

The smaller number is 5

Step-by-step explanation:

Let the smaller number be x

the other number is (17 -x) (we know they add up to 17)

2/3 of the bigger number is written as 2/3 (17 - x)

The smaller number is 3 less than that. (so subtract 3 to get x)

x= 2/3 (17 -x) - 3 <-- We have an equation, solve for x

Check 2/3 x 12 - 3 = 8 - 3 = 5

The vegetable garden has 95 ripe plants. The number of tomatoes is 16 fewer than twice the number of squashes. How many of each vegetable are ripe?​

Answers

Answer:

Tomatoes = 39.5

Squash = 55.5

Step-by-step explanation:

T (tomatoes) = S - 16

S + T = 95

we plug it in now

S + (S - 16) = 95

2s = 95 + 16

2s = 111

s = 55.5??

hm. Let's go with it

T = 55.5 - 16

T = 39.5

39.5 + 55.5 = 95
