Bob's gift shop sold a record number of cards for Mother's Day. One salesman sold 22 cards, which was 10% of the cards sold for Mother's Day. How many cards were sold for Mother's Day?

220 cards

Step-by-step explanation:

22/x = 10%/100

100x22= 2200 divided by 10= 220

x=220

22/220 = 10%/100

(I know this is 5 days late but I Hope this helped!)

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

is only a line? i think so
