Answer 1

Answer:

7 / 2, or 3.5 is between 3 and 4.

28 / 5, or 5.6 is between 5 and 6

9/4, or 2.25, is between 2 and 3.

28 / 5, or 4.6, is between 4 and 5.

Step-by-step explanation:

To multiply a whole number by a fraction, the actual way to do it is to make the non-fraction over one. So, for example, if we were to do this:

2 * (1/2)

Set 2 as 2/1 (because they are equal)

(2/1) * (1/2)

Then, multiply the numerators together and denominators together.

= 1

But, we can also save time and multiply the non-fraction with the fraction's numerator.

2 * (1/2) =

(2 * 1) / 2 =

2 / 2 =

Let's apply this to the problems we have.

7) 5 * (7/10)

Multiply 5 and 7.

(5 * 7) / 10 = 35 / 10 = 7 / 2

This is the answer (unless you want it even more simplified, which would either be 3 and 1/2, or 3.5). However to find what numbers it is between, simplify it further.

7/2 = 3.5

7 / 2, or 3.5 is between 3 and 4.

8) 7 * (8/10)

Multiply 7 and 8.

(7 * 8) / 10 = 56 / 10 = 28/5 = 5.6

28 / 5, or 5.6 is between 5 and 6

9) 3 * (3/4)

Multiply 3 and 3.

(3 * 3) / 4 = 9 / 4 = 2.25

9/4, or 2.25, is between 2 and 3.

10) 6 * (4/5)

Multiply 6 and 4.

(6 * 4) / 5 = 23 / 5 = 4.6

28 / 5, or 4.6, is between 4 and 5.

I hope this helps! Feel free to ask any questions!

Simplify: 14ba2+21ab2−ab2.

Answers

14ba^2+20ab^2 because you subtract one from 21ab^2

The given expression 14ba²+21ab²−ab² can be simplified to 14ba²+20ab².

What is simplification?

In arithmetic, the operation and interpretation of a function to make it simpler or easier to grasp is known as simplifying, and the process itself is known as simplification.

The expression is given in the question, as follows:

14ba²+21ab²−ab²

When you add or subtract similar terms, you can combine their coefficients. In this case, 21ab² and -ab² have the same base (ab²) and so their coefficients can be added together. 21 - 1 = 20, so 21ab² - ab² = 20ab².

Thus, the given expression can be simplified to 14ba²+20ab².

Answer:

Step-by-step explanation:

If we extend the horizontal line across the right-hand portion of the figure, then the figure is divided into two rectangles:

bottom: 5 m × 50 m = 250 m²

top: 18 m × 20 m = 360 m²

The sum of these areas is the shaded area:

shaded area = 250 m² +360 m² = 610 m²

The value of x is 2.

The value of y is [tex]\frac{7}{6}[/tex]

Step-by-step explanation:

We have that:

[tex]\frac{x}{3} + 1 = \frac{5}{3}[/tex]

Multiplying everything by 3

[tex]x + 3 = 5[/tex]

[tex]x = 2[/tex]

The value of x is 2.

We have that:

[tex]y - \frac{2}{3} = \frac{1}{2}[/tex]

Least common multiple between 3 and 2 is 6, which means that we multiply everything by 6.

[tex]6y - 4 = 3[/tex]

[tex]6y = 7[/tex]

[tex]y = \frac{7}{6}[/tex]

The value of y is [tex]\frac{7}{6}[/tex]

Answers

Answer:

x=5 and x=-5

Step-by-step explanation:

1. first you would subtract 6 from both sides to set the equation = to zero.

2. The equation would then be x^2-25=0.

3. that is a difference of two squares polynomial. So when you factor it, it is (x+5)(x-5)=0

4. by the zero product property, the roots are 5 and -5.
