Thomas and Silvia are brother and sister. Thomas is 12 years older than Silvia and their combined ages are 44. How old are Thomas and Silvia?


show work please

Answers

44 divided by 2 is 22, then subtract 12 from that, which is 10.

so in conclusion, thomas is 22 and silvia is 10

but that answer is wrong.

44 minus 12 is 32, now divide 32 by 2 and you get 16.

so this would mean that thomas is 32, and silvia is 16, but that doesn’t add up either.

Solve B=1/4m(s+z) for s

Answers

Answer:

[tex]s = \frac{-mz+4B}{m}[/tex]

Step-by-step explanation:

Step 1: Distribute.

[tex]B = \frac{1}{4}m * s + \frac{1}{4}m * z[/tex] [tex]B = \frac{1}{4}ms + \frac{1}{4}mz[/tex] [tex]\frac{1}{4}ms + \frac{1}{4}mz = B[/tex]

Step 2: Subtract 1/4(mz) from both sides.

[tex]\frac{1}{4}ms + \frac{1}{4}mz - \frac{1}{4}mz = B - \frac{1}{4}mz[/tex] [tex]\frac{1}{4}ms = -\frac{1}{4}mz + B[/tex]

Step 3: Divide both sides by m/4.

[tex]\frac{1}{4}ms/\frac{m}{4}=(\frac{-1}{4}mz + B)/\frac{m}{4}[/tex] [tex]s = \frac{-mz+4B}{m}[/tex]

Each side of a square patio is 10.5 feet. The patio is made up of 1.5 foot by 1.5-foot square stones. What is the number of stones in the patio? Look at the solution below.
Does it include all the steps needed to solve the problem? Explain

10.5 x 10.5 = 110.25 PLZ SOLVE THE PROBLEM
110.25 ÷ 1.5 = 73.5

Answers

The steps your teacher gave you are on the right track, but not quite 100% correct.

The first line has us find the area of the entire patio. That area being 110.25 square feet.

The next step is to find the area of each stone. That would be 1.5 x 1.5 = 2.25 square feet.

Therefore, the patio is made up of 110.25 ÷ 2.25 = 49 tiles

When arranged into a square, we'll have a 7 by 7 square set of stone tiles. Notice how 7 x 7 = 49.

Answer:

y = -1/5x - 10

Step-by-step explanation:

Pick any two points on the line.

(0,-10) and (50,-20)

find the slope by using m = y2-y1/x2 - x1(rise over run)

m = -20-(-10) / 50 - 0

m = -10/50 = -1/5 -- this is your slope

slope intercept form is y = mx + b, but we need to find your b, which is your y intercept. you find this by asking yourself, what is the y coordinate when x = 0? It is -10.

so now you have all the points you need.

y = mx + b

y = -1/5x - 10
