Madam siti bought the same lengths of red and yellow ribbons. after she used 836 cm of the red ribbon, the length of the yellow ribbon was 5 times the length of the remaining red ribbon. what was the original total length of the two ribbons?

1045 cm of red ribbon and 1045 cm of yellow ribbon

Step-by-step explanation:

Let R represent the amount red ribbon and Y represent the amouont of yellow ribbon.

Use substitution method to solve:

5(R - 836) = R

5R - 4180 = R   distributed 5 on the left side

4R - 4180 = 0   subtracted R from both sides

4R = 4180         added 4180 to both sides

R = 1045         divided both sides by 4

where are the options?

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
