Answer: E. 40
Step-by-step explanation:
The x-intercept of a line is when the y coordinate is equal to zero, so input zero in for y and solve for x to find the x-intercept.
1/2x + 3/5(0) = 20
1/2x = 20
x = 40
Answer:
2√3 = hypotenuse
√3 = side

Answer:
22.14
Step-by-step explanation:
Using the Pythagorean Theorem:
a^2 + b^2 = c^2
21^2 + 7^2 = c^2
441 + 49 = c^2
490 = c^2 (square root both sides so c^2 becomes c)
c = 22.13594363 (round to hundredths)
c = 22.14
