Answer:
The solution of the given system of equation is x = 50, y =18
Step-by-step explanation:
Here, the given system of equations are:
2x - 5y = 10 , x - 2y = 14
Now, from equation (2), we get x = 14 + 2y
SUBSTITUTE this value of y in the given equation (1)
We get: 2x - 5y = 10 ⇒ 2(14 + 2y) - 5y = 10
or, 28 + 4y - 5y = 10
⇒ 28 - y = 10
or y = 28 - 10 = 18
⇒ y = 18
Now, if y = 18, SUBSTITUTE this value of y in x = 14 + 2y
⇒ x = 14 + 2<u>y</u> = 14 + 2(<u>18</u>) = 14 + 36 = 50
Hence, the solution of the given system of equation is x = 50, y =18
So 45 more chocolate stars were sold compared to chewy squares, which makes it a ratio of 3:8, hence we can assume that (45÷5=9) is the amount sold for each ratio.
If you multiply 9 by (3+8=11), you will get 99.
Answer: £5.39
Step-by-step explanation:
500g strawberries = 4.10
100 g = 0.82
300g = 2.46
400g raspberries = 7.46 - 2.46 = 5.00
100g = 1.25
300g = 3.75
200g strawberries = 0.82 * 2 = 1.64
3.75 + 1.64 = 5.39
Answer:
156 square inches
Step-by-step explanation:
We are given the two quantities
Let
length = l = 13 inches
and
Width = w = 12 inches
The formula for the area of rectangle is:
where l is length and w is width
Putting the values of both that are given
so the area is 156 square inches ..
