Answer:
25
Step-by-step explanation:
Since they were born on consecutive years, their ages are 4 consecutive whole numbers. Let the lowest age be x. Then the other ages are x + 1, x + 2, and x + 3.
Now we add the 4 expressions and set the sum equal to 94.
x + x + 1 + x + 2 + x + 3 = 94
4x + 6 = 94
4x = 88
x = 22
The youngest one is 22.
The oldest one is
x + 3 = 22 + 3 = 25
Answer: 25
let 2nd angle = x
then 1st angle = 2x-15
then you have 90 = x + 2x-15
2x +x = 3x
so now 90 = 3x-15
add 15 to each side
105=3x
x = 105/3 = 35
1st angle = 35 degrees
2nd angle = 2(35) - 15 = 70-15 = 65
2/5p+6-3-2p+4/5p
-2p+6/5p+6-3+4
-10/5p+6/5p+3+4
-4/5p+7
-0.8p+7
Write and solve an equation:
Total earnings = $782.75 = s(40 hrs) + 1.5*s*(7 hrs)
Then 782.75 = 40s + 10.5s = 50.5s
Dividing both sides by 50.5: s = 15.5. The attendant's regular hourly wage was $15.50.
