To solve x in the equation <span>x2 = 64, we raise the whole equation to the reciprocal of the power of the variable present which means we raise it to a power of 1/2. 64 raised to 1/2 or square root of 64 is equal to positive 8 and negative 8. The solution set is {-8,8}</span>
2 1/3 + 1 3/4 = 3 10/12
5/6 = 10/12
3 10/12 + 10/12 = 3 20/12 = 4 8/12 = 4 hours 40 minutes
4 hours 5 minutes away from 10:05 would be 6 pm
subtract 35 from that and you get 5:25 pm
When comparing to thing with same rate, set up a proportion:
Inches/cost
13/.78=33/x
(13)(x)=(.78)(33) [cross multiplied]
13x=25.74 [simplified]
13/13x=25.74/13 [division property]
x=1.98
33 inches of wire will cost $1.98.
Answer:
D
Step-by-step explanation:
The first and last sequence have a common difference in them. The first having d = 4 and the second having d = 7.
The second and third have a common ratio instead and are geometric sequences. The second has r = 2, and the third having r = (-3)
Step-by-step explanation:
x + y = 985
2.95x + 9.95y = 7343.75
-2.95x - 2.95y = -2905.75
7y = 4438
y= 634 steak sandwiches
x + 634 = 985
x = 351 hot dogs
