Eva wants to make two pieces of pottery. she needs 3/5 pound of clay for one piece and 7/10 pound of clay for the other piece. she has 3 bags of clay that weigh 4/5 pounds each. how many bags of clay will eva need to make both pieces of pottery? how many pounds of clay will she have left?

we know that

Eva needs pound of clay for one piece and pound of clay for the other piece

Step 1

Find the total pound of clay for the two pieces

Eva has bags of clay that weigh pounds each.

Step 2

Find the total weigh of the bags of clay

Part a ) How many bags of clay will Eva need to make both pieces of pottery?

by using proportion

therefore

the answer Part a)

she needs bags

Part b) How many pounds of clay will she have left?

Calculate the total weigh of the bags of clay minus the total pound of clay for the two pieces

so

therefore

the answer Part b) is

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

i think the answer is seven, for if i'm being useless °ω°
