Answer:
A) 30°
Step-by-step explanation:
All triangles angles add always to 180°, so we have two already 75° + 75° = 150° thus the angle is 30°
Answer:
7/15
Step-by-step explanation:
hope the picture helps
x= total minutes -4 the 1st 4 minutes are included in the .30
total cost = .3 + .18 x
3 = .3 +.18 x
subtract .3 from each side
2.7 = .18x
divide by .18 on each side
2.7/.18 = x
15 = x
x = total minutes -4
add 4 to each side
15+4 = total minutes
they can talk 19 minutes
Answer:
(A) In step 1, the slope of the line should be One-half
Step-by-step explanation:
Terri calculated the slope as (x1 -x2)/(y1 -y2). Her first error was using this formula, when she should have used ...
m = (y1 -y2)/(x1 -x2)
= (6 -3)/(4 -(-2)) = 3/6 = 1/2
The best of the offered descriptions is ...
<em> In step 1, the slope of the line should be One-half</em>
