Answer:
£67.50
Step-by-step explanation:
On each metre of material, the shop makes a profit of ...
£6.90 -4.65 = £2.25
So, for 30 metres, the profit will total ...
30 × £2.25 = £67.50
A profit of £67.50 would be made on a 30-metre roll of material.
<span>Hypotenuse = 26 mm </span>
1st Leg = 10 mm
Other Leg = x.
By Pythagoras Theorem:
x² + 10² = 26²
<span>x² + 100 = 676 </span>
x² = 676 - 100
x² = 576
x = √576
x = 24
<span>The other leg is 24 mm</span>
Answer:
Step-by-step explanation:
y = 3x - 5
6x + 3y = 15
Substitute the first equation into the second
6x + 3(3x - 5) = 15
6x + 9x - 15 = 15
15x = 30
x = 2
Then use the answer in the first equation and solve
y = 3(2) - 5
y = 6 - 5
y = 1
