35 + 8w = 179.40
8w = 179.40 - 35
8w = 144.40
w = 144.40/8
w = 18.05 per week

In May, Liam and Charlie had the same amount of money in their savings accounts. In June, Liam deposited $140 into his account.
romanna [79]
Let's say both had an original amount of "a".

then Liam deposited 140, so it became a + 140.

then Charlie added 5% of "a" to "a", well, 5% of anything is just (5/100)*anything, so 5% of "a" is just (5/100) *a or 0.05a.

then they checked their amounts and both were equal, what the?  let's check.

\bf \stackrel{\textit{Liam}}{a+140}=\stackrel{\textit{Charlie}}{a+0.05a}\implies a+140=1.05a\implies 140=1.05a-a
\\\\\\
140=0.05a\implies \cfrac{140}{0.05}=a\implies \boxed{2800=a}

Answer:

112in²

Step-by-step explanation:

Formulas: V = \frac{lwh}{3}, V = lwh

Sub: v = \frac{4 x 4 x 6}{3}

Solve: 32

Sub: v = 4 x 4 x 5

Solve: 80

V = 80 + 32

V = 112

<u>The total volume of the figure is 112in²</u>
