Answer:
D. 8/15
Step-by-step explanation:
4/5 = 2/3 +1/3
We need to multiply by 6 to find answer as 3 is a divider of 6
4 x 6 =24
5 x 6 =30
24/30
Then we find 1/2 of 30 and add this to make 3/3
Just like 1/2 of 2 = 1 and 2+1 = 3
30 / 2 = 15
15 + 30 =45
The answer is 24/45
We then reduce this fraction by 3 as 6 + 8 do not divide into 45
24/45 = 8/15
The answer is 8/15

Make y the subject :
-----------------------------------------------------------
y - 3 = 4(x + 8)
y - 3 = 4x + 32 // Apply distributive property
y = 4x + 35 // Add 3 to both sides
-----------------------------------------------------------
Identify Slope :
-----------------------------------------------------------
Slope = 4
-----------------------------------------------------------
Find a point on the line :
-----------------------------------------------------------
When x = 0,
y = 4(0) + 35 // Sub x = 0 into the equation
y = 35 // Combine like terms
Point = (0, 35)
-----------------------------------------------------------
Answers :
(a) Slope = 4
(b) One point on the line is (0, 35)

Sue has saved $54 more than Bill
Step-by-step explanation:
Given
Sue saves $5 a week. so after 36 weeks he will have
= 36 * 5
= $180
Bill's saving is modeled by
m = 3.5w where w is the number of weeks
After 36 weeks,
The difference between savings of Bill and Sue
Hence,
Sue has saved $54 more than Bill
