Answer:
14
Step-by-step explanation:
D = 2r
D = 2(7)
D= 14
Step-by-step explanation:
2/5+2/4 (find common denominator)
The common denominator is 20
2/5 is 8/20 (multiply by 4)
2/4 is 10/20 (multiply by 5)
8/20+10/20 is 18/20
If you simplify 18/20 this would by 9/10 if you divide by 2
so the total is 18/20 or 9/10 simplified
Hope this helps!!!!
Have a nice day :)
Answer:
bald black man
Step-by-step explanation:
bald+black man, y=bbcx
Let <em>h</em> represent the cost of hot dogs and <em>p</em> represent the cost of potato chips.
Customer 1: 4h + 5p = 15.50 ⇒ 3(4h + 5p = 15.50) ⇒ 12h + 15p = 46.50
Customer 2: 3h + 2p = 9.00 ⇒ -4(3h + 2p = 9.00) ⇒ <u> -12h - 8p = -36.00</u>
7p = 10.50
p = 1.50
Customer 2: 3h + 2p = 9.00 → 3h + 2(1.50) = 9.00 → 3h + 3.00 = 9.00 → 3h = 6.00 → h = 2.00
Answer: hot dog = $1.50, potato chips = $2.00
Answer:
Step-by-step explanation:
an = a1 * r^(n - 1)
a1 = first term = 5
r = -2
n = nth term of the sequence
so it starts with 5
second term is :
an = a1 * r^(n - 1)......for second term
a2 = 5 * -2^(2 - 1) =
a2 = 5 * -2^1
a2 = 5 * -2
a2 = -10
an = a1 * r^(n - 1)....looking for a3
a3 = 5 * -2^(3 - 1)
a3 = 5 * -2^2
a3 = 5 * 4
a3 = 20
an = a1 * r^(n - 1)....looking for a4
a4 = 5 * -2^(4 - 1)
a4 = 5 * -2^3
a4 = 5 * -8
a4 = - 40
an = a1 * r^(n - 1)...looking for a5
a5 = 5 * -2^(5 - 1)
a5 = 5 * -2^4
a5 = 5 * 16
a5 = 80
an = a1 * r^(n-1)...looking for a6
a6 = 5 * -2^(6 - 1)
a6 = 5 * -2^5
a6 = 5 * -32
a6 = -160
