subtract 17, not 22, from both sides. 17 – 17 = 0 and 22 – 17 = 5. The answer should be x = 5.

Dennis_Churaev [7]

Answer:

32 mins 50 seconds

Step-by-step explanation:

Total number of hours to read weekly \geq 4

she has read for 45 minutes, so she has 4 hrs - 45 minutes = 3 hrs 15 minutes left

Dividing the time equally = 195 mins / 6

minimum number of minutes to read \geq 32 minutes 50 seconds

If two points on a line are A(10, −3) and B(12, 9), the rise is __________, and the run is __________, so the slope of the line
kherson [118]

The <u>rise</u> is the difference in y-coordinates:

  • y₂ - y₁ = 9 - (-3) = 12

The <u>run</u> is the difference in x-coordinates:

  • x₂ - x₁ = 12 - 10 = 2

The <u>slope</u> is the quotient of rise over run:

  • m = 12/2 = 6

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

If two points on a line are A(10, −3) and B(12, 9), the rise is <u>12</u>, and the run is <u>2</u>, so the slope of the line is <u>6</u>.

3. Janet is flying a kite on a string that is 75m long. The kite is 62m above the ground. Estimate the distance between Janet an
konstantin123 [22]
Answer: a) It will be a right triangle with a hypotenuse of 75 and a vertical leg that is 62. 
b) The length of the kite string is 75 (given in the problem). However, I believe you are looking for the distance from the spot on the ground beneath the kite to Janet. That is about 42.2 m.

To find the missing distance in the right triangle. You have to use the Pythagorean Theorem.  I set it up and solve it below.

a^2 + b^2 = c^2
x^2 + 62^2 = 75^2
x^2 + 3844 = 5625
x^2 = 1781
x = 42.2 (about)
