Answer 1

Answer:

A graphing calculator is more likely to be correct than if we do it by hand. When doing it by hand, we could have minor algebra errors that could change the final answer. However, the calculator has built-in algorithms that could solve the system of equations quickly and accurately. also another

Sample Response: A graphing calculator is more accurate than graphing by hand. If the slope and/or y-intercept is a fraction or decimal, it is more difficult to accurately graph by hand. Using a calculator might also be more time-efficient because it might accept a line in any form. A calculator’s window can be adjusted quickly instead of having to redraw a graph by hand when adjusting the scale.

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%

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
