K= -3/4 would be your answer
Answer: 84
Step-by-step explanation:
4 x 21 is 84 a fraction can be simplified and be a whole number so if 84 divided by 4 it will be 21 if you want to write it as a fraction it will be 21/1 which is equal to 21
Did it help? :)
45 = (x) + (x + 1) + (x + 2)
45 = 3x + 3
- 3
42 = 3x
/3
14 = x
45 = 14 + (14 + 1) + (14 + 2)
45 = 14 + 15 + 16
The ages of the 3 friends are 14, 15, and 16.
Answer:
the area of the floor that is not carpeted 19 m squared
Step-by-step explanation:
7x5 =35 m squared = area of the floor
4x4 = 16 squared =(area of the carpeted floor)
35-16 = 19
Answer:
y = -0.904, 19.904
Step-by-step explanation:
f(y) = 9
f(y) = sqrt(y + 99)
-------------------------------------------
9 = sqrt(y +99) - y
81 - 18y + y^2= y + 99
-19y + y^2 = 18
y(y - 19) = 18
y = -0.904, 19.904
(I used a calculator to solve those values)
