Answer: <u>31</u>
10

or 31/10

Step-by-step explanation:
Convert to a mixed number by placing the numbers to the right of the decimal over 10. Reduce the fraction. Then, convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator. Place this new numerator over the original denominator.

16) Amari ran three-quarter the distance Mary did. Amari ran 12 miles. Write and solve an equation that represents how far Mary

Nataliya [291]

Answer:

Step-by-step explanation:

Amari ran 3/4 distance Mary ran

A = 3/4 M

Amari ran 12 miles

12 = 3/4 M Multiply by 4

12 * 4 = 3*M Combine

48 = 3M Divide by 3

48/3 = M

M = 16

So Mary ran 16 miles.

First number has to be 2.

Second number is between 7 and 9 so has to be 8

The tens and ones place needs to sum to 6, so the tens has to be less than 6 and can't be 0, 4 or 6, so has to be 2.

The ones would then need to be 6 - 2 = 4

The number would be 2,824

The area of a triangle is 10 cm2. Its base is 3 cm less than twice its height. What is the height of the triangle?

stiv31 [10]

<h2>Answer:</h2><h2>The height of the triangle = 4cm</h2>

Step-by-step explanation:

Given, area of the triangle = 10 $cm^{2}$

Let the height of the triangle be h cm

Given, the base b is 3 cm less than twice its height.

b = 2h - 3 ... (1)

By formula, area of the triangle = $\frac{1}{2}$ bh .. (2)

substitute (1)in (2), we get

Area = $\frac{1}{2}$ (2h-3) h

10 = $\frac{1}{2}$ (2h-3) h

20 = $2h^{2} - 3h$

$2h^{2} - 3h$ - 20 = 0

solving the equation, we get x = 4, -2.5

The height of the triangle = 4cm
