larisa [96]

Step-by-step explanation:

A. Line up the decimals, then multiply as you would with whole numbers:

$21.33 \\\times 2.04 \\ = 43.5132$

B. Line up the decimals, then add as you would with whole numbers:

Note: These decimals aren't lined up exactly.

$1.115 \\ + 3.18 \\ = 4.295$

$22.061 \\ + 4.295 \\ = 26.356$

$26.356 \\ + 12.2384 \\ = 38.5944$

6(2x + 5) = 2(3x – 2) solution ? I NEED IT NOW SOMEONE PLEASE HELPPPPP!!!

AlladinOne [14]

$\fbox{x = -17/3}$

Explanation:

6(2x + 5) = 2(3x – 2)

[given]

6(2x) + 6(5) = 2(3x) + 2(-2)

12x + 30 = 6x – 4

[distributive property of equality; individually multiply each addend inside the parenthesis and simplify (distribute the terms) ]

12x + 30 = 6x – 4

–6x –6x

6x + 30 = -4

[subtraction property of equality; subtract both sides by 6x in order to keep the x term on the left side]

6x + 30 = -4

–30 –30

6x = -34

[subtraction property of equality; subtract both sides by 30 in order to keep the constant term on the right side]

6x = -34

÷6 ÷6

x = -34/6

[division property of equality; divide both sides by 6 to eliminate the coefficient of 6 in 6x in order to obtain the variable x]

x = -17/3

[GCF(greatest common factor); divide both sides by the greatest common factor until both numbers are prime (only divisible by 1 and itself]

A cheetah ran 275 feet in 3.23 seconds. How fast did the cheetah run in miles per hour? Round your answer to the nearest whole m

yawa3891 [41]

First we convert feet into meters, since 1 feet is 0.3048 m: 275 feet * 0.3048 = 83.82m.

Then we do: 83.82m / 3.23s = 25.9504644 m/s.

Then we convert that into miles per hour by 2.23694, so we do:

25.9504644 * 2.23694 = 58.0496318.

Then we round it to 58 mph.

So the answer is: The cheetah was running at 58 mph.

Hope this helped! c:
