The Tran Family drove 1,246 miles during a vacation that lasted 14 days. How many miles on average did they drive each day? :3
Svetllana [295]
To find the average miles they drove each day, divide the total amount of miles by the number of days they drove.

1246 / 14 = 89

The Tran Family drove an average of 89 miles every day.

Answer:

i think b

Step-by-step explanation:

(2,2). When x of the line is 2, y of the line must be 2.

(-2,-2). When x of the line is -2, y of the line must be -2.

(2,2). y=mx+b or 2=1 × 2+b, or solving for b: b=2-(1)(2). b=0.

(-2,-2). y=mx+b or -2=1 × -2+b, or solving for b: b=-2-(1)(-2). b=0.

The equation of the line that passes through the points

(2,2) and (-2,-2)

is

y=1x

b came out to be zero, so there is no "+b" term.

<h3>Answer:  22</h3>

===============================================

Explanation:

  • x = measure of angle 1 = angle WXY
  • 2x = twice the measure of angle 1 = measure of angle 2 = angle YXZ

The two angles mentioned combine to form angle WXZ which is 66 degrees.

angle1+angle2 = angle WXZ

x+2x = 66

3x = 66

x = 66/3

x = 22

Angle 1 is 22 degrees and angle 2 is 22*2 = 44 degrees.

Check:

angle1+angle2 = 22+44 = 66 = angle WXZ
