Answer:

c

Step-by-step explanation:

cccc

Answer 2

The required expression that represents the average of three test scores is x + y + z / 3. Option C is correct.

What is average?

The average of the values is the ratio of the total sum of values to the number of values.

Here,
The required average of three test scores,
= sum of the scores/number of scores
= x + y + z / n(x, y, z)
= x + y + z / 3

Thus, the required expression that represents the average of three test scores is x + y + z / 3. Option C is correct.

5x + 4y = 17
Y - x = 2

please help

Answers

I will solve this equation simultaneously by Substitution.

- x + y = 2
5x + 4y = 17

Solve - x + y = 2 for y:
- x + y + x = 2 + x (here we add x to both sides)
y = x + 2

Substitute x + 2 for y in 5x + 4y = 17
5x + 4y = 17
5x + 4(x + 2) = 17
5x + 4x + 8 = 17
9x + 8 = 17 (simplify both sides of the equation)
9x + 8 + (-8) = 17 + (-8) (add -8 to both sides)
9x = 9
9x/9 = 9/9 (divide both sides by 9)

x = 1

Substitute 1 for x in y = x + 2
y = x + 2
y = 1 + 2
y = 3 ( simplify both sides of the equation)

Therefore x = 1 and y = 3

Step-by-step explanation:

Answer:

X = 6


Step-by-step:

2(3x + 4) = 44
Simplify both sides
6x + 8 = 44
Subtract 8 from both sides
6x = 36
Divided both sides by 6
X = 6

Answer:

8 grams

Step-by-step explanation:

The balance is in equilibrium, so the weights of the two sides are equal.

Let the weight of a square be s.

Left side: 2s + 4

Right side: s + 3(4) = s + 12

The weights are equal, so we set the two expressions equal.

2s + 4 = s + 12

s = 8

Answer: The weight of a square is 8 grams.

Question 2: The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.

Answer: x=14

only #2

Step-by-step explanation:

Step 1: Subtract 3x from both sides.

2x+6−3x=3x−8−3x

−x+6=−8

Step 2: Subtract 6 from both sides.

−x+6−6=−8−6

−x=−14

Step 3: Divide both sides by -1.

-x/-1=-14/-1

3(5 - x) = 7x - 2​

Answers

Answer:

exact form: x=17/10

Decimal form: x=1.7

mixed number form: 1 7/10

Answer:

x = 17/10 (as a fraction) or x = 1.7(as a decimal) or x = 1 7/10(as a mixed number)

Step-by-step explanation:

3(5-x) = 7x - 2

3 * 5 - 3* x = 7x - 2 (brackets means multiply)

15 - 3x = 7x - 2 (when over equal sign negative changed to positive)

15 + 2 = 7x + 3x

17/10 = 10x/10 (cross-cancel cuz u tryna isolate the x)

17/10 = x

What is the equation of the line that passes through (1, 2) and (8,9) in slope-intercept form?

Answers

Answer:

The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: [tex]y = x+1[/tex]

Step-by-step explanation:

The slope-intercept form of line is given by the formula:

[tex]y = mx+b[/tex]

Here m is the slope and b is the y intercept

Given

[tex](x_1,y_1) = (1,2)\\(x_2,y_2) = (8,9)[/tex]

First of all, the slope has to be found

[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{9-2}{8-1}\\m = 1[/tex]

Putting m=1 in the equation

[tex]y = x+b[/tex]

Putting the point (1,2) in the equation to find the value of b

[tex]2 = 1+b\\b = 2-1\\b = 1[/tex]

The equation is:

[tex]y = x+1[/tex]

Hence,

The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: [tex]y = x+1[/tex]
