O y = 2x + 2
O y = 2x
O y = 4x + 2

Answers

Answer:

y=2x

Step-by-step explanation:

we can set x=number of week, and y=inches

as you can see, 1 week-> x=1 :y=2(1) = 2 inches

                         2 week-> x=2 :y=2(2)=4 inches

**if we substitute x to  y = 2x + 2 and y = 4x + 2, it will not works.

Answers

Answer: e. 2h + 3 = 10; h = 3.5h

Explanation:

Jane can run 2 miles per hour. (2h)

He need to run 10 miles in total and has done 3 so far. (+ 3 = 10)

The equation can be written:

2h + 3 = 10
2h = 7
h = 7/2 = 3.5

O 75

Answers

55 because alternate interior angles are congruent and then you can do some basic algebra
Answer: angle 5 is 55 degrees.

Start by solving for angle 2 by using the linear pair rule: all linear angles sum to 180

125 + angle 2 = 180

angle 2 = 55

Now, we know that line l and line m are parallel. If we look at these two lines plus the left side of the triangle, we can see it forms a z shape. This means angle 2 and angle 5 are alternate exterior angles. This means they are congruent.

4 meters 85 millimeters to milimeters.

Answers

Answer:

4085

Step-by-step explanation:

4 meters = 4000 millimeters + 85

= 4085

Answer:

By changing 4 meters 85 millimetres to milimetres we get 4085 milimetres

Step-by-step explanation:

In the first step change 4m to mm

We know that 1m = 1000mm

So, 4m = 4000mm

Now add 4000mm to 85mm

= 4000mm+85mm

= 4085mm

If x=1/8 what is the value of y when 2/x = y/4

Answers

Answer:

y = 64

Step-by-step explanation:

x = 1/8

Substituting x in the equation,

=> 2/(1/8) = y/4

=> 2 x 8 = y/4

=> 16 = y/4

=> y/4 = 16

=> y = 16 x 4

=> y = 64

The value of y will be;

⇒ y = 64

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;

The expression is,

⇒ 2/x = y/4

Now,

Since, The expression is,

⇒ 2/x = y/4

Substitute x = 1/8, we get;

⇒ 2/(1/8) = y /4

⇒ 2 × 8 = y / 4

⇒ 16 × 4 = y

⇒ y = 64

Thus, The value of y = 64
