Johnny is making key chains. He uses 8 green beads for each key chain. How many green beads will he need to make 9 key chains? 13 key chains?
Drag the numbers to the correct boxes.

72 green beads for 9 keychains, 104 for 13 keychains.

Step-by-step explanation:

since he uses 8 beads for every chain, multiply 8 by the number of chains made

please thank

a) 72   b) 104

Step-by-step explanation:

To figure out how many beads you need to make the key chains you simply need to multiply the number of the beads used by the number of the key chains that are being made

Johnny uses 8 beads for each key chain.

So:

a) 9 key chains = 8 x 9

The answer is 72

b) 13 key chains = 8 x 13

The answer is 104

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
