The lines s and t intersect at point R.<br><br> What is the value of y?<br><br> y = ____
ozzi
Assuming that the angles are congruent, then y = 29.
4y - 8 = 79 + y
4y = 87 + y             Add 8 to both sides
3y = 87                  Subtract y from both sides
y = 29

20 onions cost £3.00. 25 potatoes cost £6.25. Mr Dean needs 14 onions and 16 potatoes. Calculate the total cost.
enot [183]

Answer:

The total cost of 14 onions and 16 potatoes will be £6.10

Step-by-step explanation:

Let onion be n and potato by p

20n = £3.00

1n = £3.00/20

= £0.15

25p = £6.25

1p = £6.25/25

= £0.25

The cost of 1 onion is £0.15, and 1 potato is £0.25

Then the cost of 14 onion and 16 potatoes together will given as

14n + 16p

substituting the values of n and p, we will have

14*0.15 + 16*0.25

2.1 + 4

= £6.10

Write an equation of the line perpendicular to
AysviL [449]

Answer:

From general equation of a line:

y = mx + b

m » slope, b » y-intercept.

but perpendicularly:

m _{1} \times m _{2} =  - 1 \\  - 3 \times m =  - 1 \\ m =  \frac{1}{3}

at point (6, 2):

2 = ( \frac{1}{3}  \times 6) + b \\ 2 = 2 + b \\ b = 0

therefore, equation is :

{ \boxed{ \boxed{y =  \frac{1}{3} x}}}
