Joey and Doug hung out at the mall on Saturday. They spent 1-hour shopping for clothes and 1 hour and 30 minutes at the food court. Then they spent 30 minutes at the video arcade before heading home. It was 2:45 P. M. when Joey and Doug left the mall. What time did they start shopping for clothes?

They started shopping for cloths at 11:45 AM

Step-by-step explanation:

First of all we have to calculate the whole time that they spent in the mall starting from shopping.

They spent 1 hour on shopping, 1 hour and 30 minutes at food court and 30 minutes in video arcade which makes:

as 30 minutes is equal to half hour so we used 0.5 in place of it.

Now we know that they left at 02:45 PM. We have to see what time it was 3 hours ago.

Hence,

They started shopping for cloths at 11:45 AM

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y
