Let Alex's age is x and June's age is y y - x = 7 .........(1)
(x+5) + (y+5) =31
x + y = 21 .........(2)
by adding 1 and 2
2y = 28
y = 14
x = 7
Answer:
35
Step-by-step explanation:
All triangles = 180 degrees so as shown there is a right angle(90 degrees) and a 55 degree angle and there is A.
So you will subtract 90 and 55 from 180 to find A.
=35 degrees
Now or B , A and B are vertical angles which means they are congruent or equal to each other so the measure of angle B is 35.
For the 1st hour the cost is $50 whatever is the duration (providing it's 1 hour max.
From one hour and onward the cost becomes an additional $25 per quater of an hour.
If y is the cost and x the number of hours, then the equation becomes :
y =50 + 0.25.x or y =1/4x + 50
4.25c+2.75b=40 would be the correct answer because you’re trying to find how many they can get of each with only 40 dollars
