4x - 5y + 20 = 0
<u> - 20 - 20</u>
4x - 5y = -20
4x - 4x - 5y = -20 - 4x
-5y = -20 - 4x
<u>-5y</u> = <u>-4x - 20</u>
-5 -5
y = ⁴/₅x + 4
The slope would be ⁴/₅.
Answer:
The third one, y = 5 x 10
Step-by-step explanation:
y = number of Kate's pens, 5 = how many times more pens Kate has than Mark, and 10 = how many pens Mark has.

Answer:
Children 188
Adults. 115
Step-by-step explanation:
Let the no. of children be x and adults be y
x + y = 303
x = 303 - y. .... .....(1)
1.75x + 4.80y = 881. ...........(2)
Substituting,
1.75(303-y) +4.80y = 881
530.25 -1.75y + 4.80y = 881
530.25 + 3.05y = 881
3.05y = 881 - 530.25
y = 350.75 / 3.05 = 115 = adults
Children = 303-115 = 188
Answer: 11 2/15
Explanation: (3+7) (1/3+4/5)
10 + 17/15
10 + 1 2/15
11 2/15
