Answer:
1.=6 2.=7.6 3.= 2.2 6.= 3.50
Step-by-step explanation:
1. 78-27 =51 51 divided by 8.50=6
2.150-27=123 123 divided by 16=7.6
3. 14-65=51 51 divided by 23=2.2
6. 10 divided by 3= 3.5
Answer:
no solutions
Step-by-step explanation:
-4x-4=-4(x+2)
Distribute the negative
-4x-4 = -4x-8
Add 4x to each side
-4x+4x-4 = -4x+4x-8
-4 = -8
Since this is not true there are no solutions
The questions seem to be about the law of sines:
5
26/sin(73) = x/sin(11) = 5
6
8/sin(104) = x/sin(29) = 17
7
25/sin(86) = x/sin(21) = 9
8
29/sin(58) = x/sin(26) = 15
9
18/sin(28) = x/sin(47) = 8
10
6/sin(17) = x/sin(137) = 6
Answer:
Option C and Option D have exactly one solution.
Step-by-step explanation:
The equation will have exactly one solution when it completely solves and we get value of x.
Checking all choices
(Choice A)
-19x + 18 = -19x + 18
-19x+19x=18-18
0=0
(infinite solutions)
(Choice B)
-19x -18 = -19x + 18
-19x+19x=18+18
0≠36
(no solution)
(Choice C)
19x + 18 = -19x + 18
19x+19x=18-18
38x=0
x=0
(One solution)
(Choice D)
19x - 18 = -19x + 18
19x+19x=18+18
38x=36
x=36/38
x=18/19
(One solution)
So, Option C and Option D have exactly one solution.
