Which statement correctly explains how kasi could find a solution to the following system of linear equations using elimination

jarptica [38.1K]

A. She can multiply the bottom equation by -4 and then add the equations to solve for h.

-4g - 15h = -17

4g - 20h = -52

Add them to get

-15h = -17

-20h = -52

From here, you can solve for h.

Madelyn hikes 190.5 meters up a mountain. If she is 62% of the way up, how tall is the mountain?

ira [324]

Answer:

307 Meters

Step-by-step explanation:

$\frac{62}{100} = 190.5\\
Cross multiply:

62w = 100(190.5)

Multiply 100 by 190.5:

62w = 19,050

Solve for w:

Divide both sides by 19,050 to isolate the variable and get the answer

19,050/62 = 307.25.....

~ After rounding to the nearest percent, the answer is 307$
