Answer:

x = -8

Step-by-step explanation:

2x - 2 =  - 18

Collect like terms and simplify

2x  =  - 18 + 2 \\ 2x =  - 16

Divide both sides of the equation by 2

\frac{2x}{2}  =  \frac{ - 16}{2}

Simplify

x =  - 8

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
marta [7]

Answer:

a) Eva will need 2 bags of clay to make both pieces of pottery.

b) She will have leftover \frac{11}{10} pounds of clay.

Step-by-step explanation:

Hi

a) We have to find the total amount of clay, as she needs \frac{3}{5}pound=P_{1} and \frac{7}{10}pound=P_{2}, so P_{1}+P_{2}= \frac{3}{5} +\frac{7}{10} =\frac{6+7}{10}=\frac{13}{10}pounds, is the total amount of clay. Then as we Know that one bag of clay has \frac{4}{5} =\frac{8}{10} pounds, It isn´t enough, but with two bags 2*\frac{8}{10}=\frac{16}{10}  pounds, It is enough clay.

b) She will have leftover \frac{16}{10} -\frac{13}{10} =\frac{3}{10}pounds of the second bag, then we add the third one, so \frac{3}{10} +\frac{8}{10} =\frac{11}{10}pounds are leftover.
