180 = 65 + (x-5) + x
-65 -65
115 = x - 5 + x
115 = 2x - 5
2x = 120
x = 60
The angle measures are 65, 60, and 55 degrees.
Answer:
r = -1
Step-by-step explanation:
To get r isolated, you have to divide each side by -7
7 divided by -7 is -1, therefore r = -1
Answer:
D. 11
Step-by-step explanation:
T = total savings
w = number of weeks
Paige:
T = 350 + 25w
Cindy:
T = 190 + 40w
In how many weeks will Cindy have more money in her savings than Paige
Equate the total savings of both of them
350 + 25w = 190 + 40w
Collect like terms
350 - 190 = 40w - 25w
160 = 15w
w = 160/15
w = 10.67
Approximately,
In 11 weeks, will Cindy have more money in her savings than Paige
Check:
Paige:
T = 350 + 25w
= 350 + 25(11)
= 350 + 275
= 625
Cindy:
T = 190 + 40w
= 190 + 40(11)
= 190 + 440
= 630
Answer:
or 8.944
Step-by-step explanation:
Simplify
Square root both sides to get x by itself
or 8.944
No it is not a function, because a function cannot have more than one output per input. When x=-3, there are two solutions shown: (-3,2) and (-3,3), therefore it cannot be a function.
