Answer:

a supplementary angle is when two angles share the same vertex and when you add up both of their degrees it equals 180 degrees

Step-by-step explanation:

say i have an angle on both sides and they share the same point. One side is 96 degrees and the other is 84. When you add them up it equals 180 degrees. This would be a supplementary angle.

A complementary angle would be the same thing but instead of it being 180 degrees, the sum would be 90 degrees. A good way to remember this is the C in complementary comes first in the alphabet so the lowest number is 90. And S in supplementary is farther than C so 180 Is larger than 90 .

Last week Martha sold brownies. And cookies at a back sale she sold 60 bowlines and 42 cookies on Saturday and 28 brownies and 5

elena55 [62]

Answer:

Martha earns $65.6 over the weekend.

Step-by-step explanation:

Brownies sold by Martha on Saturday = 60

Cookies sold by Martha on Saturday = 42

Brownies sold by Martha on Sunday = 28

Cookies sold by Martha on Sunday = 54

Total brownies sold by Martha over the weekend = $60+28=88$

Total cookies sold by Martha over the weekend = $42+54=96$

Cost of a brownie = $0.20

Cost of a cookie = $0.50

Total cost of brownies sold over the weekend = $88\times \$0.20 = \$17.6$

Total cost of cookies sold over the weekend = $96\times \$0.50 = \$48$

∴ Total money Martha earned over the weekend = $\$17.6+\$48=\$65.6$ (Answer)

6x+3(4x-2)=5(2x-8) the answer is -17/4 but can someone explain how to get that answer? plz help lol

Sergeu [11.5K]

Answer:

<h2> $x = - \frac{17}{4}$ </h2>

Step-by-step explanation:

$6x + 3(4x - 2) = 5(2x - 8)$

Expand the terms in the bracket and simplify

That's

$6x + 12x - 6 = 10x - 40 \\ 18x - 6 = 10x - 40$

Using the subtraction property subtract 10x from both sides of the equation

$18x - 10x - 6 = 10x - 10x - 40 \\ 8x - 6 = - 40$

<u>Add 6 to both sides of the equation</u>

$8x + 6 - 6 = - 40 + 6 \\ 8x = - 34$

<u>Divide both sides by 8</u>

$\frac{8x}{8} = - \frac{34}{8}$

<u>Reduce the fraction with 2</u>

We have the final answer as

$x = - \frac{17}{4}$

Hope this helps you

Amirah's family is driving to her uncle's house. The family travels 383.5 miles between 10:15 am and 4:45 pm. Calculate the fami

ddd [48]

Answer:

The family's average rate of travel for the day was 59.0 MPH.

Step-by-step explanation:

From 10:15AM to 4:45PM, they travelled a distance of 383.5 miles and a total of 6 hours and 30 minutes.

There are 60 minutes in an hour. 30 minutes translates into 1/2 an hour or .5

So, 6.5 hours and a total distance of 383.5 miles.

Velocity (MPH) = Distance (in miles) / Time (in hours)

MPH means Miles Per Hour

Variables:

Velocity (MPH) = x

Distance (in miles) = 383.5

Time (in hours) = 6.5

Plug in the variables into the formula

x = 383.5 / 6.5

Divide

x = 59.0 MPH
