Step-by-step explanation:

Answer:

Part 1: 61 degrees Part 2: 90 degrees

Step-by-step explanation:

m<a = 180 - m<b - m<c - 29

m<c = 29

m<b = 90-29

m<b = 61

m<a = 180 - 61 -29 -29

m<a = 61 degrees

m<c + m<b = 29 + 61

m<c + m<b 90 degrees

Answer:

I'll explain

Step-by-step explanation:

So you have to multiply first so

2 times 3 is 6

then 6 to the third power would be

6x6x6

6x6=36 then

36x6=216

then you would do 216-10 which is 206

Answer:false 5-(-3)<8

Step-by-step explanation:

8 is not less than 8

Answer:

this can be the answer

because in given question there is no relation between equations

Well is it 8  3/4? Because i got no idea

Answer:

8 3/4

Step-by-step explanation:

The reason is because on the graph the most common size was 1 3/4, so you count how many x's there was. There were 5 x's so you multiply 1 3/4 by 5 and you get 8 3/4

Answer:

4.9

Step-by-step explanation:

first step is to add up 44 and 77, to get 121

the goal is to get a value of 180 degrees, so taking the info we have gathered lets do 180-121 to give us 58

58 minus 9 is 49 and divide by ten the decimal gives us

4.9

10 times 4.9 is 50 plus 9 makes 58

Step-by-step explanation:

The test had '10' 4-point questions and '30' 3-point questions in the math test.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Sophia’s math test is worth 130 points and has 40 problems.

And, Each problem is worth either 4 points or 3 points.

Now,

Let number of 4 point questions = x

And, Number of 3 point questions = y

Since, There are 40 problems.

So, We get;

x + y = 40   .... (i)

And, Each problem is worth either 4 points or 3 points.

So, We can formulate;

4x + 3y = 130   .... (ii)

Solve equation (i) and (ii) as;

Multiply by 4 in equation (i), we get;

4x + 4y = 160

Subtract from equation (ii),

y = 30

And, x + y = 40

x = 40 - 30

x = 10

Thus, The test had '10' 4-point questions and '30' 3-point questions in the math test.

Answer:

[tex](-\frac{2}{7},-\frac{65}{7} )[/tex]

Step-by-step explanation:

By steps in the image:

Step 1:

To eliminate, you need one of the coefficients to be the same in both equations. We will use the term "-6x" found in the first equation.

To get this, multiply the entire second equation by 6 and simplify using the distributive property. The new equation is:

[tex]6x-6y=54[/tex]

Step 2:

Now you need to subtract the first equation and the new version of the second equation. By doing this, the "-6x" in both equations will cancel each other out.

Step 3:

Solve for x in the given equation by:

Step 4:

Solve for y by:

Solution:

[tex](-\frac{2}{7},-\frac{65}{7} )[/tex]

Answer:

t=9.48n+119.88

Step-by-step explanation:

where t is the total cost of 12 t-shirts, and n is the number of words in the design

0.75n+9.99 is the equation for custom made t-shirts, and n represents the number of words in the design

t=12(0.75n+9.99)

where t is the total cost of t-shirts, and n is the number of words in the design

When simplified, this becomes t=9.48n+119.88

Answer:

-2 and 3/4 because of the reflective postualte

Step-by-step explanation:

Answer:

-1/4

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the equation of the lines expressed as:

L1: y = 2/3 x - 3 and L2: y = -3/2 x +2

Comparing to the standard form of equation of a line y= mx+c

The slope of L1 is m1 = 2/3

The slope of line L2 is -3/2

Since their slope are not the same, therefore the lines are not parallel to each other.

For two lines to be perpendicular, the product of their slope is -1.

Let's check for both lines:

Check the product of their slope;

m1m2 =2/3 * -3/2

m1m2 = -6/6

m1m12 = -1

Since the product of their slope is -1, hence the lines are perpendicular to each other.

Answer:

Option C is correct

Answer:

Addition Property

Step-by-step explanation:

Because since there are the plus sign there is no x - or a ÷sign so its Addition Property

13 + 7 = 20 ⇒ 13 + 7 +2 = 20 + 2 represents addition property of equality.

" Equality means representation of any two quantities using mathematical expression with the sign of 'equals to'."

According to the question,

Given,

13 + 7 = 20

Add '2' both the side  of the given equality we get,

⇒ 13 + 7 + 2 = 20 + 2

Add both the sides represents  addition property of equality.

Hence, Option(D) is the correct answer.
