▪ Answer:
n = 17
d = 8
▪ Step-by-step explanation:
Hi there !
1 nickel = 5c
1 dime = 10c
$1.65 = 165c
n + d = 25 => n = 25 - d
5n + 10d = 165
replace n
5(25 - d) + 10d = 165
125 - 5d + 10d = 165
5d = 165 - 125
5d = 40
d = 8 (dimes)
n = 25 - d
n = 25 - 8
n = 17 (nickels)
Good luck !
Answer:
θ = π/3, 5π/3
Step-by-step explanation:
2 cos θ - 1 = 0
2 cos θ = 1
cos θ = 1/2
8 -<u> 8</u>, 16, 24, 32, 40, 48
4 - 4, <u>8</u>, 12, 16,
So the LCM of 8 and 4 are C) 8
8 - 8, 16, <u>24</u>, 32, 40, 48
6 - 6, 12, 18,<u> 24</u>, 30
So the LCM of 8 and 6 are A) 24
8 - 8, 16, 24, 32, <u>40</u>, 48
10 - 10, 20, 30, <u>40</u>, 50
The LCM of 8 and 10 are B) 40
Hope this Helps!!
are there any word choices?
x2-4 = 0
x2= 4
x = 2 or x = (-2)
