Based on the fact that Kayden is the youngest and their ages are consecutive and add up to 90, the Kayden is 21.
<h3>How old is Kayden?</h3>
To find Kayden's age, assume that it is x and use the formula:
90 = x + (x + 1) + (x +2) + (x +3)
Solving for x gives:
90 = 4x + 6
4x = 90 - 6
x = 84 / 4
x = 21

Step-by-step explanation:
Answer:
Step-by-step explanation:
4.5b + 8.5c = 175
b + c = 22.......b = 22 - c
4.5(22 - c) + 8.5c = 175
99 - 4.5c + 8.5c = 175
-4.5c + 8.5c = 175 - 99
4c = 76
c = 76/4
c = 19......there are 19 cats
b + c = 22
b + 19 = 22
b = 22 - 19
b = 3 <==== there are 3 birds
Answer:
12m^2
Step-by-step explanation:
volume = 48 m^3
l*b*h = 48
12*h = 48
h = 4 m
baSe of prism will be made of l and b
so area is 12 m^2
