**Answer:**

3(4+x)

which can be simplified to 12+3x

6785 - 6496 = 289 units

289 x 13p = 3757p

3757p = £37.57

37.57 + 21.45 = £59.02

**Answer:3*(7*d)+(4e)=3*7d+4e**

**Step-by-step explanation:**

1. 5x/2 +y=-3

2. False

3. y= -5x-37 because y=mx-b

4. y= 1/5 x - 1 because y=mx-b

M= the slope and b represents the intercept.

Z = 7
As given,
19 = z + 12
19 - 12 = z
7 = z
z = 7
