Answer:
1. 9x = 63
Step-by-step explanation:
9x = 63
if x=7, then 9(7) = 63
9*7=63
63 = 63
Answer:
see explanation
Step-by-step explanation:
to determine which of the ordered pairs are on the line, substitute the coordinates of the point into the left side of the equation and if the value obtained equals the right side then it lies on the line.
(, - )
2 + 7 = 9 ⇒ correct
(- 5, - 6 )
- 15 + 24 = 9 ⇒ correct
(1, - )
3 + 6 = 9 ⇒ correct
(- 1, 3 )
- 3 - 12 = - 15 ⇒ incorrect
The 3 ordered pairs
( , - ), (- 5, - 6), (1, - )
All line on the line 3x - 4y = 9
Answer:
Step-by-step explanation:
a. 29/8 + 2(19/4) + 3(27/8) = 29/8 + 38/4 + 81/8 = 29/8 + 76/8 + 81/8 = 186/8 in.
b. 186/8 times 2 = 372/8 in
c. the shortest plane would be 27/8 and the largest would be 19/4 or 38/8.
If you subtract the two, you get 11/8. The difference is 11/8 in.
The measure of angle RKL is 63 degrees.
The measure of the inscribed angle RKL times 2 is equal to the arc that it forms.
Therefore, we can write and solve the following equation:
2(-2 + 23x) = 64 + 24x - 2
-4 + 46x = 62 + 24
22x = 66
x = 3
Now, input 3 into the expression for the angle and you will have 67.
-2 + 23(3)
-2 + 69
67
A hexagon. 1/3 fits into 2 6 times, so that means there are 6 sides.
