Select a value: addition property of equality

1 answer:

Whitepunk [10]3 years ago

3 0

Answer:

Addition prop of equality, multiplication prop of equality, multiplication prop. of equality

Step-by-step explanation:

For the first one, we know that in order to solve the equation, we need to add 3 to both sides of the equation. When you add a value to both sides of the equation, you're using the addition property of equality.

For the second one, we know that in order to solve the equation, we need to multiply both side by 1/6 (to cancel the 6 out on the left side). When you multiply something to both sides of the equation, you're using the multiplication property of equality.

For the third one, we know that in order to solve the equation, we must multiply both sides of the equation by 5. Like the second problem, this would be the multiplication property of equality (since you're multiplying both sides of the equation by the same thing).

What is the value of x?

erica [24]

Answer:

x = 24

Step-by-step explanation:

(2x - 4) + (3x + 5) + (2x + 11) = 180°

Combine like terms:

7x + 12 = 180

Subtract 12 on both sides:

7x = 168

Divide 7 on both sides:

x = 24

What is the simplified expression for 6 (2 (y x))? 6 y 12 x 12 y 12 x 12 y 8 x 8 y 8 x

stellarik [79]

The simplified expression for 6(2( y + x)) is 12y + 12x.

Accordin to the given question.

We have an expression

6(2( y + x))

Therefore,

The simplified expression for 6(2( y + x)) is given by

6(2(y + x))

= 6(2y + 2x) (by distributive law)

= 12y + 12x (by distributive law)

Hence, the simplified expression for 6(2( y + x)) is 12y + 12x.

What is the sum of 1 2/5 and 5 3/4

Art [367]

Answer:

$7\frac{3}{20}$

Step-by-step explanation:

<em>Hey there!</em>

Well to add this we need to pu it in improper form.

7/5 + 23/4

Now we need to find the LCM.

5 - 5, 10, 15, 20, 25, 30

4 - 4, 8, 12, 16, 20, 24, 28

So the LCD is 20.

Now we need to change the 5 and 4 to 20.

5*4 = 20

7*4 = 28

<u>28/20</u>

4*5=20

23*5=115

<u>115/20</u>

Now we can add 28 and 115,

= 143/20

Simplified

7 3/20

<em>Hope this helps :)</em>

Simplify [view attached image]

pav-90 [236]

<u>Given</u>:

The given expression is $(\sqrt{5})( \sqrt[3]{5})$

We need to simplify the given expression.

<u>Simplification</u>:

Let us simplify the given expression.

Rewriting the given expression, we have;

$5^{\frac{1}{2}} \cdot 5^{\frac{1}{3}}$

Let us apply the exponent rule $\:a^b\cdot \:a^c=a^{b+c}$ , we get;

$5^{\frac{1}{2}+\frac{1}{3}}$

Taking LCM, we have;

$5^{\frac{3+2}{6}}$

Simplifying, we get;

$5^{\frac{5}{6}}$

Thus, the simplified value of the given expression is $5^{\frac{5}{6}}$

Hence, Option a is the correct answer.
