if I went to store with 90.00 and spent 36.81 and got 20% off what would I have left need answer fast thanks

vichka [17]

I'm guessing the 20 percent off is from the $36.81 so you take 36.81 times 0.80 making it $29.448. Take 90 dollars and minus that amount.

Answer: $60.552
Rounded Answer: $60.55 or $60.60 or $61

Not sure if this helped, but yeah.....

Use the formula d = rt to ﬁnd the distance, rate, or time

Varvara68 [4.7K]

Answer:

16. d = distance

r = rate

t = time.

We know that the rate = 4, and time = 11.

=> d = 4 * 11

=> d = 44

17. We know that distance = 36, and time = 4.

=> 36 * r* 4

=> 36 = 4r

=> 36/4 = 4r/4

=> r = 9

Please help me I don’t understand this

Lyrx [107]

When you're given a point and the slope of a line, it is often easiest to write its equation in point-slope form.

This is $y-y_1=m(x-x_1)$ , where $(x_1,y_1)$ is the ordered pair for the point you are given and m is the slope.

Here, you would write $y-8=-3(x-7)$ . Then, you simplify to get to slope-intercept form, which is $y = mx+b$ , where b is the y-intercept.

$y-8=-3(x-7) \\ y=-3x+29$

The correct answer is A.
