4(3w+5)-2w=70
10w+20=70
10w+20-20=70-20
10w=50
10w/10=50/10
w=5

Answer:

or, 12w+24-2w=70

or,12w-2w=70-24

or,10w=46

or,w=46/10

therefore, w=4.6

given triangle GHI with G(4,-3), H(-4,2) and I(2,4), find the perpendicular bisector of HI in standard form.
nekit [7.7K]
The perpendicular bisector would be the line that connects with the line HI at a 90 degree angle and in the mid-point. This means that we would have to find the slope of the line HI and take the opposite. The slope of HI is 1/3. This means that the slope of the perpendicular line is -3. Now we must solve for the line that crosses through the midpoint. y=mx+b we know that m=-3 and that the midpoint is at -1,3 so x=-1 and y=3.  3=(-3)-1+b. We then solve for b and find it to be 0.  So the final answer is y= -3x

What’s the unit rate for three dollars for 2 1/2 hours of work
Maru [420]

The unit rate for three dollars for 2 1/2 hours of work will be $1.2 using the concept of unitary method.

<h3>What is unitary method?</h3>

The unitary method is a technique that involves determining the value of a single unit and then calculating the value of the requisite number of units based on that value. The term unitary refers to a single or unique entity. As a result, the goal of this approach is to determine values in reference to a single unit. The unitary technique is a method for determining the value of any necessary quantity by first obtaining the value of the unit (one) quantity.

Here,

$3 for 2.5 hours of work,

1 hour will cost $x,

3/2.5=x/1

2.5x=3

x=$1.2

Using the unitary technique, the unit rate for three dollars for two and a half hours of labour will be $1.2.

I need help with these two
djyliett [7]

Answer:

Part 1) Slope-intercept form

Part 2) The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee

Step-by-step explanation:

Part 1) we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

y=2.50+2.20x

This is a linear equation in slope intercept form

where

m=2.20

b=2.50

Part 2) we have that

x -----> represent the number of miles

y ----> represent the total charge in dollars

The slope is

m=\$2.20\ per\ mile ---> unit rate

The y-intercept is

b=\$2.50 ----> initial value or flat fee

therefore

The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee
