Meredith picked 4 times as many green peppers as red peppers. if she picked a total of 20 peppers how many green peppers did she pick/

She picked 4 red peppers, and 16 green peppers.

Step-by-step explanation:

The best way to solve this is by setting up an equation. You can set it up as so: 20=x=4x. X would represent the number of red peppers she picked, since the amount of red peppers is and elaboration of how many green peppers there are (there are 4 times as many green peppers). Then you solve. You add like terms to get 20=5x, then divide both sides by 5. This leaves you with 4 red peppers. Then multiply 4 by 4 to get the amount of green peppers, in this case 16. Lastly add the 2 numbers gotten and see if they = 20 to check your answer.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
