Answer:

5x - 2 = 77

x = 15.8

Step-by-step explanation:

a number - x

times 5 - 5x

minus 2 - 5x - 2

equals 77 - 5x - 2 = 77

77 + 2 = 79

79 ÷ 5 = 15.8

5(15.8) - 2 = 77

Find the greatest common factor of 11m^3 and 13m^2.<br> Help!!!
LUCKY_DIMON [66]
The greatest common factor of 11m^3 and 13m^2 is m^2.  11 and 13 don't really have a greatest common factor (they're both prime numbers), and m^2 goes into each of them.

Two percent of Jennie’s skin cells were burned when she escaped from a fire. If 3.7×10^10 of her skin cells were burned then, ho
gulaghasi [49]

1813\times10^9 cells were not burnt when Jennie escaped from the fire.

<u>Solution:</u>

Given:

2% of skin cells were burnt i.e, 3.7\times10^{10} of skin cells were burnt.

To find:

Number of skin cells that were not burnt

We can write 3.7\times10^{10} \text{ as } 37\times10^{9}

Therefore, by equating the values we get,

2% of the cell is 37\times10^9

1% of the cell is \frac{37\times10^9}{3}=18.5\times10^9

As, 1% of the cell is 18.5\times10^9

98%  of the cell will be 98\times18.5\times10^9=1813\times10^9

\therefore \text{ skin cells that are not burnt is } 1813\times10^9

2. In this case, A=2.4, B=8.6, and C=5.6
3. Next, write it out in the proper formula: (2.4+8.6/2)•5.6
4. Add 2.4 and 8.6 first, giving you 11
5. After that, divide 11 by 2, which gives you 5.5
6. Lastly, multiply 5.5 by 5.6
7. This will give you 30.8

Jerry is buying a new large screen television for his game room. He knows that the diagonal of the television measures 42.1 inch
bixtya [17]
Remember that the area of a rectangle is length times width; since we don't know the width, we'll use the Pythagorean theorem to find it first:
l= \sqrt{h^{2}-c^{2}  }
Where l is the leg, and h the hypotenuse. We know that one of the legs, the base has a measures 34.3 inches and the hypotenuse a measures 42.1 inches.
Replace the values to get:
l= \sqrt{42.1^{2}-34.3^{2}  }
l=24.4=w
Now that we know the width (w), we just net to multiply it by the length to get our area:
A=(24.4)(34.3)=836.9

We can conclude that the correct answer is <span>B) 836.9 in.</span>
