Answer:

Step-by-step explanation:
step 1
Find the slope of the line that is perpendicular to the given line
we have
-----> given line
The slope of the given line is

Remember that
If two lines are perpendicular, then their slopes are opposite reciprocal
therefore
The slope of the line that is perpendicular to the given line is

step 2
Find the equation of the line in slope intercept form

we have

substitute

solve for b

therefore

1.20*2 = 2.40 + 0.60 = 3.00
1.20 + 0.60 = 1.80
1.20 per egg and 0.60 for toast
1st answer
Answer: 11 and 24
Step-by-step explanation:
Given
There are 35- 50 cents and 20 cents coins
The total of them is 10.3 euros
Suppose no of 50 cents coins is x and 20 cents is y
so we can write

Also,

Solving (i) and (ii) we get

There are 11 fifty cent and 24 twenty cents coins
When adding fractions, you only add the numerator if the denominators are the same.
In this case, the answer would be:

or

Which when simplified is:
