Get photo math an app just for math it gives u the answers and how to solve it
You do 9+3 which equals 12 then you multiply that by 4
Graph it like you would a normal equation except if it's not "equal to" it's a dashed line instead of solid line. Then shade the appropriate area on the graph,
for example..
y > 2x +1
is graphed as a dashed line y = 2x +1 since it doesn't actually equal y.
y is greater than the line/equation so the area above is shaded where y is bigger
Answer: Team one = 1/5
Team 2 = 4/21
Team A is the fastest
Step-by-step explanation: Answer: Team one = 1/5
Team 2 = 4/21
Team A is the fastest
Step-by-step explanation: TEAM A
Tammy working alone in 1hr can clean 1/2
Melissa working alone in 1 hr can clean 1/3
working together in 1hr ,let x represent the area they will clean we have
+
= 1/x
⇒ 3 + 2 = 1/x
5 = 1/x
x = 1/5
TEAM B
Santay working alone can clean 1/4
Leticia working alone in 1 hr can clean 4/5
working together in 1 hr ,let y represent the amount they clean, we have
+
= 1/y
4 + 5/4 = 1/y
21/4 = 1/y
y = 4 /21
comparing x and y , 1/5 is greater than 4/21 , therefore Team A is faster
