2 answers:

8 0

1/4x + 7 = 1/2x + 5....u basically sub one y in for the other y
7 - 5 = 1/2x - 1/4x
2 = 2/4x - 1/4x
2 = 1/4x
2 / (1/4) = x
2 * 4/1 = x
8 = x

y = 1/4x + 7
y = 1/4(8) + 7
y = 2 + 7
y = 9 <====

Answer:

x = 55 degree

Step-by-step explanation:

let the another angle be y

y+108=125 (sum of two interior opposite angle is equal to the exterioe angle formed)

y=125-108

y=17

y+x+108=180 degree (sum of interior angle of a triangle)

17 + x + 108 =180

x + 125 =180

x = 180-125

x=55

A bottle contains 255 coins. 1/3 of the coins are ?1.00. 110 of the coins are 50p coins. the rest are 20p coins. work out the to

aliina [53]

Answer:

£152.

Step-by-step explanation:

We have been given that a bottle contains 255 coins. 1/3 of the coins are £1.00.

Let us find 1/3 of 255 to find the number of £1 coins.

$\£1\text{ coins}=\frac{1}{3}\times 255$

$\£1\text{ coins}=85$

This means we have £85.

We are also told that 110 of the coins are 50 p coins.

$\text{Value of 50 p coins}=\£0.50\times 110$

$\text{Value of 50 p coins}=\£55$

Let us figure out number of 20 p coins by subtracting the number of £1 coins and 50 p coins from 255.

$\text{Number of 20 p coins}=255-(85+110)$

$\text{Number of 20 p coins}=255-(195)$

$\text{Number of 20 p coins}=60$

$\text{Value of 20 p coins}=\£0.20\times 60$

$\text{Value of 20 p coins}=\£12$

Now let us find total value of the coins contained in the bottle by adding the values of £1 coins, 50 p coins and 20 p coins.

$\text{The total value of the coins}=\£85+\£55+\£12$

$\text{The total value of the coins}=\£152$

Therefore, the total value of the coins contained in the bottle is £152.
