Barbara sells iced tea for $1.49 per bottle and water for $1.25 per bottle. She wrote an equation to find the number of drinks s
umka2103 [35]
I remember doing this question. The question went like:
<span>1.25x + 1.49 = 100
What error did Barbara make in writing the equation?
And the answer would be that Barbaras equation did not consider the number of ice tea drinks. Hence, </span>She put the correct price in the equation but she didn't put the (x) number of iced tea drinks. In other words,This is because she has added 1.25 X the number of water bottles sold to 1.49, the cost of one iced tea. 
So, the correct equation would be:
1.25x +1.49y = 100
Would really appreciate if you would put me as Brainliest answer.

How do I fine the perimeter of these triangles?
arsen [322]

constant of proportionality => COP

3: P(triangle ABC) = 84

COP = 18/15 = 1.2

Since you are finding the larger triangle, multiply the other numbers by 1.2

25 * 1.2 = 30

28 * 1.2 = 33.6

17 * 1.2 = 20.4

add them all up (answer up top)

5: P(triangle ABC) = 61.2

COP = 9/5 = 1.8

Since you are finding the larger triangle, multiply the other numbers by 1.8

9 * 1.8 = 16.2

13 * 1.8 = 23.4

12 * 1.8 = 21.6

add them all up (answer up top)

6: P(triangle RST) = 110

RP and PT are congruent, this means that PT is also 20

COP = 40/20 = 2

Since you are finding the larger triangle, multiply the other numbers by 2

25 * 2 = 50

20 * 2 = 40

10 * 2 = 20

add them all up (answer up top)

Question 17 i need help answer is -16 but don’t know how
Mila [183]

Answer:

-16

Step-by-step explanation:

-k² -(3k-5n)+4n k=-1 , n= -2

= -(-1)² - ( 3(-1) -5(-2) )+4(-2)

= -1-(-3+10)-8

= -1-(7)-8

= -1-7-8

= -16

Help please!<br> Find x<br> x=<br> 7<br> 7/2<br> /(14)
Dahasolnce [82]

Answer:

x = 7

Step-by-step explanation:

recognize that this is a right triangle with one of the  internal angles = 45°. This means that the other angle not shown is 180 - 90 - 45 = 45°

This makes the triangle an isosceles triangle.

If so, x must be the same length as the other side adjacent to 90°

i.e x = 7
