In a triangle the midline joining the midpoints of two sides is parallel to the third side and half as long ⇒

2(3x + 2) = 2x + 20
6x + 4 = 2x + 20
6x - 2x = 20 - 4
4x = 16
x = 16/4
x = 4

midsegment = 3x + 2 = 3*4 + 2 = 12 + 2 = 14

Ann is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.
ipn [44]

Answer:

Ans: greater than 40 mileage  Company A will charge less than Company B

Step-by-step explanation:

as company A charges a fix amount $93 for any distance and company B charges variable amount starting from $65.there will be a certain mileage after that the amount charged by company B should be greater than company A.

let for greater than m mileage company A will

charge less than company B.

charge for company A for m mileage= $93

charge for company B for m mileage= $65 + $0.70*m

so,

   93  ≤ 65+0.70*m

93-65 ≤ 65+0.70*m -65

  28   ≤ 0.70*m

28*10 ≤ 7 *m

280     ≤ 7m

280/7  ≤ 7m/7

    40  ≤ m

Write the linear equation in slope-intercept form.<br><br> -6x + y = 19
Aleonysh [2.5K]
Your answer would be y= 6x + 19


You get rid of the variable on the left side by adding it to both sides giving you y = 6x + 19
Hope it helps

A worker at a snack stand opened a new box of cups. The first day he used 30 cups , the second day the worker used 15 percent of
Sholpan [36]

Answer:

Step-by-step explanation:

the first day he used 30 cups

the second day he used 15% of the remaining cups...a total of 90 cups were used on second day.

so 15%of the remaining cups = 90.....so if u let x be the total cups, then the remaining cups would be x - 30

15% of (x - 30) = 90.....turn ur percent to a decimal..." of " means multiply

0.15(x - 30) = 90

0.15x - 4.5 = 90

0.15x = 90 + 4.5

0.15x = 94.5

x = 94.5 / 0.15

x = 630 total cups <==

lets check..

start with 630 cups....used 30 the first day....leaving u with 600 cups....15% of the remaining cups = 90.....so 15% of 600 = 90....lets check it

15%of 600 = 0.15(600) = 90...yep, thats correct....there were 630 cups in the new un-opened box
