Callie solved this one-variable equation. When she was done, she tried to verify her answer, but found that it was wrong. Can yo

u find her mistake? 1 2 (4k + 8) = 10 1. 2k + 16 = 10 2. 2k = −6 3. k = −3 What was Callie’s mistake? Callie should have added 10 to both sides in step 2. In step 1, when Callie distributed the One-half to the 8, she multiplied incorrectly. Callie divided by 2 instead of multiplying by 2 in step 3. Callie should have added 16 to both sides in step 2.

Stolb23 [73]

Answer:4.5\ ft^3

Step-by-step explanation:

Given

Measurement of box 1\frac{1}{2}\times 1\frac{1}{2}\times 2

suppose Length L=1\frac{1}{2}=\frac{3}{2}\ ft

Breadth B=1\frac{1}{2}=\frac{3}{2}\ ft

height H=2\ ft

Volume of Cuboid=L\times B\times H

Volume of Packaging box V=\frac{3}{2}\times \frac{3}{2}\times 2

V=\frac{9}{2}\ ft^3

Find x and y, given that line WS and line VT are parallel. Show all work!
bulgar [2K]

In the given diagram, the traingles USW and UTV are similar triangles and thus the following ratio equality applies to them.

\frac{VT}{WS} =\frac{VU}{WU}=\frac{TU}{SU}..........(Equation 1)

Checking the diagram given, we see that:

VT=y, WS=22, VU=8, ST=x-2

WU=WV+VU=12+8=20

TU=5

SU=ST+TU=(x-2)+5=x+3

Thus, substituting the required values in (Equation 1) we get:

\frac{y}{22}=\frac{8}{20}=\frac{5}{x+3}

Now, as can be clearly seen, to find y we will use the first two ratios as:

\frac{y}{22}=\frac{8}{20}

y=\frac{8\times 22}{20}=8.8

In a similar manner, to find the value of x we can use the last two ratios:

\frac{8}{20}=\frac{5}{x+3}

After cross multiplication we get:

5\times 20=8(x+3)

Which can be simplified as:

x+3=\frac{100}{8} =12.5

Thus, x=12.5-3=9.5

Therefore, the required answer is:

x=9.5 and y=8.8
