$L+T=34 \ => \boxed{L=34-T}\\\\ 2(L-5)+3(T-5)=61 \\\\ 2(34-T-5)+3T-15=61 \\\\ 68-2T-10+3T-15=61 \\\\ T+43=61 \\\\ T=61-43 \\\\ \boxed{T=18 \ years \ has \ Todd} \\\\ L=34-18 \\\\ \boxed{L=16 \ years \ has \ Louis}$

Solve for x in the diagram below (picture included)

Sever21 [200]

Answer:

Step-by-step explanation:

We know the straight line is equal to 180°, and the three angles that make it are (x+12),100°, and x. We can use the equation 180=(x+12)+100+x to find x.

180=(x+12)+100+x

We can remove the parentheses and combine x plus x to 2x.

180=100+2x+12

100+12=112

180=112+2x

-112 -112

68=2x

Jaime has 8/10 of a candy bar left over. He wants to split it into 1/3 pieces.

Valentin [98]

Answer:

2 pieces.

Step-by-step explanation:

To identify how many pieces he can split with 8/10 of a candy bar, divide 8/10 by 1/3.

Divide 8/10 by 1/3:

$\frac{8}{10} / \frac{1}{3}=$

Find the Ricipricol, then flip the sign:

$\frac{8}{10} (\frac{3}{1} )=$

Multiply:

$\frac{8}{10} (\frac{3}{1})=\frac{24}{10} =\frac{2.4}{1}$

2.4 represents how many pieces of chocolate he can make with 8/10 of a candy bar.

However, 2.4 pieces can't be made, therefore he can only make 2 full pieces.
