4. Building codes typically require inches rise 11 nches in tread for
standard stairs. Although stairs can have
up to 8 inches in rise and 12 inches in tre
ead, each change makes the stairs less comfortable
to navigate. In a new home being built,
the builder needs to construct stairs to code focalourdeck. The dimensions of the
full staircase will be 70 inches vertically and 110 inches horizontally.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

one set of data has more variation than the other. hope this !
