Isabella punches 14.62 yards of fabric to make a costume she needs to cut it into 3 4.2 yard pieces how much fabric will she have leftovers

There will be 3 full 4.2-yd pieces plus a 2.02-yd leftover piece.

Step-by-step explanation:

Divide 14.62 yd by 4.2.  Determine the remainder as a decimal fraction:

14.62 yd

= 3 full 4.2 yd pieces, plus 0.5 piece left over.

4.2 yd

Note that "0.5 piece" would be 0.48(4.2) yds long, or 2.02 yds.

Then you'd have three pieces of length 4.2 yds and 1 leftover piece of length 2.02 yd.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

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
