Answers

Answer:

c.126 red

Step-by-step explanation:

red+green+yellow=350

10% out of 350 are yellow

0.1 times 350=35

350-35=315

3/5 out of 315 are green

red is not green so

2/5 of what is left is red

2/5 of 315 is red

2/5 times 315=430/5=126

126 red

Answer:

Step-by-step explanation:

This is just a algebra problem. That means that we need to combine like terms. Variable on one side, number on the other side.

[tex]\frac{3}{4} c-\frac{7}{12} +\frac{7}{24}c+\frac{2}{3} -\frac{1}{6} c[/tex]

Then combine like terms and solve.

Select the correct answer. Nina can stitch of a dress in 4 hours. If d represents the number of dresses and h represents the number of hours, which equation represents this proportional relationship? A. d = 6h B. 3d = 4h C. D. d = 4h E.

Answers

Answer: I believe it’s D

Step-by-step explanation:

Answer:

I believe the correct answer would be d= 4h

This is because D is represented as dress and H is hour. So if it takes Nina to make a dress in 4 hours the obvious expression would be per every dress it took 4 hours or in other words d= 4h.
