Can someone help<br> Me please

Kay [80]

Answer: -6. 4. -3,75. 37.

Step-by-step explanation: -20|+10-2²= -6, since a minus×minus give you a + therefore -2²=4.

2³+(-8)= 12-8=4, a minus×plus gives you a minus.

-2,50+(-1,25)=-2,50-1,25=-3,75. |-10|+|20|-5²-(-2)=-10+20+25+2=37.

What is y in the equation

xxMikexx [17]

Answer: y=16

Step-by-step explanation:

1. Remove parentheses

6y−6−4y=26

2. Simplify

2y−6=26

3. Add 6 to both sides

2y=26+6

4. Simplify

2y=32

5. Divide both sides by two

y= $\frac{32}{2}$

6. Simplify

y=16

Hope this helps, have a BLESSED and wonderful day! :-)

in 2020 there were about 282 million gas powered cars on the road this number is expected to decrease at a rate of 3.1% per year

Rus_ich [418]

Answer:

≈ 240,000,000 people

Step-by-step explanation:

$3.1 \cdot 5 = 15.5$

$15.5$ ≈ $16$

$Y = X(1 - P\%)\\Y = 282,000,000(1 - 16\%)$

$p = 16\%/100 = 0.16\\Y = 282,000,000(1 - 0.16)\\Y = 282,000,000(0.84)\\Y = 236,880,000\\$

$236,880,000$ ≈ $240,000,000$
