Answer:
£2
Step-by-step explanation:
Let T represent T-shirt and H represent hat
5T + H = £27.00
2T + H = £12.00 Subtract two equation
5T + H - 2T - H = £27 - £12 ➡ 3T = £15 and T = £5 this is the cost for a t-shirt
If a t-shirt costs £5 and 2 t-shirt + a hat costs £12 then a hat costs £2
Answer: The hypotenuse is 53 (approximately)
Step-by-step explanation: In this question we shall apply the Pythagoras theorem which states that;
AC^2 = AB^2 + BC^2
Where AC is the hypotenuse and AB and BC are the two other sides. Having been given that the two other sides are 36 and 39 units respectively, the hypotenuse is now,
AC^2 = 36^2 + 39^2
AC^2 = 1296 + 1521
AC^2 = 2817
Add the square root sign to both sides of the equation
AC = 53.0754
Therefore the hypotenuse is approximately 53 units.
Answer:
4. 180 degrees
Step-by-step explanation:
The sum of the measures of the interior angles of a triangle is 180 degrees.
This is true of all triangles.
Answer: 4. 180 degrees

Answer = $44
1. Divide $140 by 5/7. It will give us how much Kelvin had originally, which is $196
(I got 5/7 by doing 7/7 - 2/7)
2. Find 2/7 of 196 by multiplying them. This is 56....meaning that Kelvin gave James $56
3. Subtract 100 - 56 to find how much James had before this, which is $44.
