Find the simplified value of each expression:
a) 3 and a half divided by 5 over 4
b) 7/3x + 5/2x
b) 29/6x
Rearrange the following equation into the form y = mx+c, and identify the gradient and y-intercept values.
y +2x -5 =0
y = -2x + 5. Gradient =-2, y-intercept = 5
The following numbers are in direct proportion. Fill in the missing ones and write an equation to show the relationship.
x =12 y=3
x= 8,y =
x = 16, y =
x = 20, y =5
x = 4,y =
y= 4x. OR x = y/4
Farmer Lulu is struggling with her maths homework. She needs to write an equation and an expression for the area of this shape. Can you help her?
Equation: Area = 6x squared + 10x + 4
Expression: 6x squared + 10x + 4
y =2x+3
Reasoning: So we could find the gradient and y-intercept/ so the graph can be drawn faster
Write the following as a simplified fraction and find x for b. Give any decimal answers to two decimal places.
a) 2x/2 + 3x/12
b) 3x squared/8 + x squared/6 = 96
a) 5x/4
b) 9x squared/24 + 4x squared/ 24 = 96. x = 13.31

6x+8<16. x<1.3 recurring.
(Non-calculator question) If a varies directly as b and b = 46 when a = 80.5, find:
a) the formula for b in terms of a
b) the value of b given a = 241.5
c) the value of a given b = 20.125
Give any decimal answers to three decimal places.
a) b = 1.75a
b) b = 138
c) a = 35.219
Write the equation for the following line:
Rearrange this equation into the form y = mx + c, and state the gradient and y-intercept of the line.
6y - 18 = 12x
y = 2x + 3
