# Exam-Style Questions.

## Problems adapted from questions set for previous Mathematics exams.

### 1.

GCSE Higher

The diagram shows an isosceles triangle (not drawn to scale).

Angle ABC = angle ACB, AB = $$3x+8$$ and AC = $$5x-7$$.

Use an algebraic method to find the value of $$x$$.

### 2.

GCSE Foundation

The diagrams show a triangle and a rectangle (not drawn to scale).

The area of the rectangle is six times larger than the area of the triangle. Find the value of $$x$$

### 3.

GCSE Higher

The perimeter of the triangle is the same length as the perimeter of the square.

Find an expression for the length of one side of the square in terms of a. Give your answer in its simplest form.

### 4.

GCSE Higher

Aimee, Natasha and Ruby play hockey.

• Aimee has scored 6 more goals than Natasha.
• Ruby has scored 5 more goals than Aimee.

If altogether they have scored 35 goals, how many goals did they each score?

### 5.

GCSE Higher

Luke, Leia and Han swim lengths of a swimming pool to raise money for charity.

• Luke swims 20 more lengths than Han
• Leia swims twice as many lengths as Han
• Altogether they swim 232 lengths.

How many lengths did each person swim?

### 6.

GCSE Higher

Solve the simultaneous equations

$$5x+2y=0$$ $$5x-3y=15$$

### 7.

GCSE Higher

Two rectangles, not drawn to scale, are shown below. All measurements are in centimetres. Both rectangles have the same areas. Work out the perimeter of the rectangle on the left.

### 8.

GCSE Higher

Solve the simultaneous equations:

$$3x-5y=18$$ $$4x+2y=11$$

### 9.

GCSE Higher

The area of rectangle PQRS (not to scale) is 80cm2.

(a) Show that $$x^2 + 14x = 40$$.

(b) Find the value of $$x$$ giving your answer correct to three significant figures.

### 10.

GCSE Higher

A rectangular sheet of paper can be cut into two identical rectangular pieces in two different ways, either by cutting along line A or by cutting along line B.

When the original sheet of paper is cut along line A, the perimeter of each of the two pieces is 56 cm.

When the original sheet of paper is cut along line B, the perimeter of each of the two pieces is 64 cm.

What is the perimeter of the original sheet of paper?

### 11.

GCSE Higher

Rätselzeit school has an annual sports day in which the mathematics teachers are in charge of the scoring system.

The points scored for throwing the discus are worked out using the formula:

$$p = 15(d – 4.2)$$

where $$p$$ is the number of points scored when the discus is thrown a distance of $$d$$ metres.

(a) How many points does Homer score for throwing the discus a distance of 52 metres?

(b) How far did Marge throw the discus if she scored 492 points?

The points scored for running 400 metres are worked out using the formula:

$$p = 6(95 – t)^2$$

where $$p$$ is the number of points scored when the time taken is $$t$$ seconds.

(c) Lisa scores 1014 points for the 400 metres race. Work out the time, in seconds, it took Lisa.

The formula for the number of points scored in the 400 metres race should not be used for $$t\gt n$$.

(d) State the value of $$n$$ giving a reason for your answer.

### 12.

GCSE Higher

Two numbers are chosen so that the sum of their squares is 25.

If those numbers are represented by $$x$$ and $$y$$ they will also satisfy the equation:

$$y-3x=13$$

Use an algebraic method to find two possible values of $$x$$ and $$y$$ .

### 13.

GCSE Higher

The prices of two watches are in the ratio $$a:b$$.

When the prices are both increased by £10, the ratio becomes $$5 : 7$$.

When the prices are both reduced by £10, the ratio becomes $$1 : 3$$.

Express the ratio $$a:b$$ in its lowest terms.
