Answer:

34 hours

Step-by-step explanation:

Lets call M the number of hours that Maddie volunteered. Ryan volunteered 1 + 3×M hours, and altogether they volunteered 45 hours, so:

1 + 3×M + M = 45

1 + 4M = 45 Subtract 1 in both sides

4M = 44 Divide both sides by 4

M = 11 hours

So Maddie volunteered 11 hours, and Ryan volunteered

1 + 3×11 = 34 hours

almond37 [142]

Answer:

Triangle 2 is a transformation from Triangle 1, and has been reflected across the x-axis.

Step-by-step explanation:

We can conclude that Triangle 2 is a reflection across the x-axis because the x values stayed the same but the y values are negative.

In a reflection across the x-axis, the x values will stay the same. But, since it is flipped across the x-axis, the y values will become negative.

So, Triangle 2 is a reflection across the x-axis.

abruzzese [7]

Answer:

\frac{k}{5+14} = 13 : k = 247\\

Step-by-step explanation:

\frac{k}{5+14} = 13

Multiply both sides by 19:

\frac{19k}{5+14} = 13 * 19

Simplify:

k = 247

Hope I helped, if so may I get brainliest and a thanks?
