Answer:

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

90 - 12b = - 3b + 63

- 12b + 3b = 63 - 90

- 9b = - 27

- b = - 27/9

-b = -3

b = 3

to find the measure of MQR:

-3*3 + 63 = 54°

to find the measure of LQR:

180 - 54 = 126° + 1 = 127°

====================================================

Work Shown:

Angles MQX and LQR are vertical angles, so they are equal to one another.

angle MQX = angle LQR

-4a+139 = 4a+123

-4a-4a = 123-139

-8a = -16

a = -16/(-8)

a = 2

Use this to find each angle

We get the same value 131 each time, so this confirms we have the correct value for 'a', and it confirms our answer for angle LQR.

Step-by-step explanation:

Answer:

It would be 212

Step-by-step explanation:

212 tens divided by 10 is 21.2 tens.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

There are 212 tens.

And tens is a digital device.

So, 212 tens divided by 10,

=212/10

= 21.2

Therefore, the value is 21.2 tens.

Answer:

They aren't equivalent because when using P.E.M.D.A.S you solve what is in the parenthesis first. After you solve what is in the parenthesis the two expressions are completely different.  

Step-by-step explanation:

100/(5)=20    (4)/5= .8

The requried results of the two expressions are different (20 and 0.8), the expressions are not equivalent.

Expression 1:
100 ÷ (25 ÷ 5)

Evaluate the expression inside the parentheses.

25 ÷ 5 = 5

Replace the expression inside the parentheses with its result:

100 ÷ 5

Perform the division:

100 ÷ 5 = 20

So, the result of Expression 1 is 20.

Expression 2:
(100 ÷ 25) ÷ 5

Evaluate the expression inside the first set of parentheses.

100 ÷ 25 = 4

Replace the expression inside the first set of parentheses with its result:

4 ÷ 5

Perform the division:

4 ÷ 5 = 0.8

So, the result of Expression 2 is 0.8.

Since the results of the two expressions are different (20 and 0.8), the expressions are not equivalent.

The reason why they are not equivalent is due to the order of operations. In Expression 1, we first divide 25 by 5 and then divide 100 by the result, while in Expression 2, we first divide 100 by 25 and then divide the result by 5.

Answer:

20 over 4 llllllllll

Answer:

A. Yes

B. No

C. Yes

D. No

Step-by-step explanation:

A and C has an equivalent ratio.

B and D do not.

2:5 x2 = 4:10

Because if we multiply 2 on both the 2 cups of fruit juice and the 5 cups of water we'll get

4:10 which is the ratio of A

If we divide both the 2 cups of fruit juice and the 5 cups of water with 2 we'll get...

2 ÷ 2 = 1

5 ÷ 2 = 2.5

1:2.5 is the ratio for C.

So both C and A are correct

The rest, B and D, are not equivalent.

Answer:

17/100

Step-by-step explanation:

The unknown quantity in the given expression is 17/100

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is an expression, 8/10 + x = 97/100, we need to find x,

So,

8/10 + x = 97/100

Subtract 8/10 from both the sides,

8/10 + x -8/10 = 97/100-8/10

x = 97/100-8/10

Multiply by 100 both the sides,

100 x = 100(97/100-8/10)

100x = 97-80

100x = 17

Divide the equation by 100

x = 17/100

Hence, the unknown quantity in the given expression is 17/100
