HELP!!pls solve this rn pls. pls i rly need it now<br> 5 (-2a – 8 ) &lt; -9a +4
Ann [662]

5(-2a-8) < -9a + 4

Use distributive property on left side:

-10a -40 < -9a + 4

Add 40 to both sides

-10a < -9a + 44

Add 9a to both sides

-a < 44

Multiply both sides by -1 and reverse the inequality sign:

A > -44

Answer: a > -44

Andre wants to put a carpet down on a circular room that has a diameter of 14 feet
Fantom [35]

Answer:

49 pi

Step-by-step explanation:

I'll assume you want to know how big the carpet is. You need to find the area of the room, which is a circle. The area of a circle is given as pi*r^2, where r is the radius. The diameter is twice the radius, so as the problem gives us a diameter of 14, the radius would be 7. Plug in 7 for r, and we get 49pi.

Kareem cannot decide which of two washing machines to buy. The seling price of
Phantasy [73]

The first washing machine is 50% off- so it'd be $260 for the final price

The second washing machine was marked down by 20%, so it'd be 416. But then it was marked down another 30% so the final price would be $291

Since the first washing machine was just 50% of $520, it's a better deal rather than 20% of $520, then 30% of $416

I hope my answer was clear enough!
