69.1 is already a decimal.
Step-by-step explanation:
3x - 2x + 8 = 12; x=4
Now, Evaluate the value of x
3(4) - 2(4) + 8 = 12
12 - 8 + 8 = 12
12 + 0 = 12
12 = 12
Answer:
Slope of the line = 2
Step-by-step explanation:
Slope of a line through two points lying on the line and is given by,
Slope =
From the figure attached,
Given line is passing through two points (0, 1) and (1, 3).
Therefore, slope of the line will be,
Slope =
= 2
Answer:
x = 17, y = 34
Step-by-step explanation:
Since the triangle is right use trig ratios to find x and y
note exact values sin30° = , tan30° =
sin30° = =
multiply both sides by y
y sin30° = 17 ( divide both sides by sin30° )
y = = 34
tan30° = =
multiply both sides by x
x tan30° = 17 ( divide both sides by tan30° )
x = = 17
