The expression is 3x.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

We can write an expression as,

(1/3) x (9x)

= (9/3)x

= 3x

Thus,

The expression is 3x.

Which of these equations is for a line perpendicular to y-3=5(x-2)?

Answers

Answer:

Step-by-step explanation:

y-3=5(x-2) (rearrange this to be in slope- intercept from) (add 3 to both sides)

y = 5(x-2) + 3 (distribute parentheses)

y = x(5) - 2(5) + 3

y = 5x -10 + 3

y = 5x - 7

recall that for a line with gradient m, the gradient of the perpendicular line will be - (1/m)

hence in our case, our gradient of the original line is 5, hence the gradient of the perpendicular line is -1/5

From the choices, the only one that is consistent with this is C

i.e choice C:

5y + x = 25

5y = -x + 25

y = -(1/5) x + 5 ===> gradient of -1/5

Nikki has 3 pieces of yarn. 5/6 ft long, 5/3 ft long, 3/2 ft long arrange from shortest to longest. draw a number line model

Answers

TO compare these fractions you would have to find the lcm first of 6,3 and 2
The lcm is 6
Next, you would have to multiply all fractions by a number so the denominator is 6
5/6 is already good
5/3 times 2 = 10/6
3/2 times 3 =9/6
The new fractions are 5/6 10/6 and 9/6
In shortest to longest, the answer is 5/6 9/6 10/6
