Apple: £20
Banana: £60

I believe this is the answer because between the two problems there is a difference of £60. So I saw three apples were gone from the next so 60 divided by 3 is 20. Then we need to find the banana price. 20 x 7 = 140. 200 - 140 is 60. So the banana is 60 and the apples are 20.

Write an equation for a line that is parallel to 2x+5y=15 and passes through the point (-10, 3)​
Lyrx [107]

Answer:

The equation of the line is,

y =  -  \frac{2}{5} x - 1

Step-by-step explanation:

First, you have to write it in a form of y = mx + b :

2x + 5y = 15

5y = 15 - 2x

y = 3 -  \frac{2}{5} x

y =   - \frac{2}{3} x + 5

When both lines are parallel to each other, they will have to same gradient value. So the equation of the line is y = (-2/5)x + b. Next, you have to find the value of b by substutituting (-10,3) into the equation :

y =   - \frac{ 2}{5}x + b

let \: x =  - 10,y = 3

3 =  -  \frac{2}{5} ( - 10) + b

3 = 4 + b

3 - 4 = b

b =  - 1

Braden about three adult tickets and one child ticket at the movie theater and paid $32. Karen bought seven adult tickets and tw
Rama09 [41]

The cost of one adult ticket is $8 and cost of one child ticket is $8.

Step-by-step explanation:

Let,

Cost of one adult ticket = x

Cost of one child ticket = y

According to given statement;

3x+y=32       Eqn 1

7x+2y=72     Eqn 2

Multiplying Eqn 1 by 2

2(3x+y=32)\\6x+2y=64\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(7x+2y)-(6x+2y)=72-64\\7x+2y-6x-2y=8\\x=8

Putting x=8 in Eqn 1

3(8)+y=32\\24+y=32\\y=32-24\\y=8

The cost of one adult ticket is $8 and cost of one child ticket is $8.
