PART 2:
3x-3 \geq -18  add 3 on both sides... 3x \geq -15
 divide 3 on both sides... x \geq -5

plug both answers together..

A plastic bin contains red yellow and green keychains out of 350 keychains 10% or yellow off the remaining keychains three sets
pantera1 [17]

Answer:

The question is not comprehensive, the comprehensive question is:

A plastic bin contains red, yellow, and green key chains. Out of 350 key chains, 10% percent are yellow. Of the remaining key chains, 3/5 are green. How many red key chains are inside the bin?

There are 126 red key chains in the plastic bin

Step-by-step explanation:

The plastic bin contains keychains of red, yellow and green colours.

According to the question, the total keychains in the bin are 350.

10% of this keychains are yellow i.e. 10/100 × 350 = 35

Thus, 35 keychains are yellow in colour.

This means, we have 350 - 35 = 315 keychains consisting of red and green colours left.

The question further says that 3/5 of the remaining keychains (315) are green i.e. 3/5 × 315 = 945/5 = 189

Thus, there are 189 green keychains in the bin.

To get the number of red keychains in the plastic bin, we add the number of yellow and green keychains, and subtract the sum from the total keychains (350).

We have 35 (yellow) + 189 (green) = 224 yellow and green keychains.

Hence, red keychains = 350 (total keychains) - 224 (yellow and green)

= 126 red keychains

There are 126 keychains in the plastic bin.
