Solve x−1=8 Math Problem

Answer:

x=36

Step-by-step explanation:

first subtract 8 into 80, then divide it with two and you will find the answer for x

Answer:

36

Step-by-step explanation:

Start off by subtracting 8 from each side.

Once you do that your equation will now look like this--->2x=72

To get ride of the 2 you have to divide by 2 on each side.

2x=72

/2  /2

x=36

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

Answer:

19.Flase 20.True

Step-by-step explanation:

hope this helps sorry if not

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.

Given:

The expression is

[tex]\dfrac{10^0r^{-11}s}{3^2}[/tex]

To find:

The simplified answer using only positive exponents.

Solution:

We have,

[tex]\dfrac{10^0r^{-11}s}{3^2}[/tex]

[tex]=\dfrac{(1)r^{-11}s}{9}[/tex]

[tex]=\dfrac{r^{-11}s}{9}[/tex]

Using properties of exponents, we get

[tex]=\dfrac{s}{9r^{11}}[/tex]            [tex]\left[\because a^{-n}=\dfrac{1}{a^n}\right][/tex]

Therefore, the required answer is [tex]\dfrac{s}{9r^{11}}[/tex].

The required simplified value is [tex]\frac{s}{9r^{11}}[/tex]

Exponent: Exponent is defined as the method of expressing large numbers in terms of powers.

The given expression is,

[tex]10^0r^{-11}\frac{s}{3^2}[/tex]

The given expression can be simplified as,

[tex]10^0r^{-11}\frac{s}{3^2} =1\times r^{-11}\frac{s}{9} \\=\frac{s}{9r^{11}}[/tex]

So, the simplified value of the given expression is,

Answer:

Because [tex]x = y[/tex], then the solution is unique.

Step-by-step explanation:

Given

[tex]Ax = b[/tex]

[tex]Ax=0[/tex]

See comment for complete question

Let there be two solutions x and y.

Such that:

[tex]Ax = b[/tex] and [tex]Ay = b[/tex]

Since:

[tex]Ax = Ay = b[/tex]

Then:

[tex]Ax - Ay = b - b[/tex]

[tex]Ax - Ay = 0[/tex]

This implies that:

[tex]Ax - Ay = A(x-y) = 0[/tex]

The only trivial solution is:

[tex]Ax - Ay = A(x-y) = 0[/tex]

Such that:

[tex]x -y = 0[/tex]

Then

[tex]x = y[/tex]

Because [tex]x = y[/tex], then the solution is unique.

Answer:

D

Step-by-step explanation:

The slope is 1/2, which will be a constant, making it a linear function.

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.
