If you plug in 7 for n, you get
(7+1)(7-2).
Simplify that.
(8)(5)
Simplify that and you get the 7th term of the particular sequence is,
40
Hope it helps :D
Answer: n=6
Step-by-step explanation:
2^3 x 4^3 = 2^3 x 2^n = 2^9
(2×2×2) ×(4×4×4) = (2x2x2) ×2^n=(2x2x2x2x2x2x2x2x2)
8 x 64 = 8x 2^n = 512
512= 8x 2^n = 512
divide all through by 8 so that 2^n can stand alone
512/8 = (8x 2^n)/8 = 512/8
64 = 2^n = 64
express 64 as a base of 2
2^6 = 2^n = 2^6
since they all have same base, cancel out the base.
therefore,
6=n=6
n = 6
Answer:
120 miles
Step-by-step explanation:
Distance = 150 miles
train 1 = 60 mph
train 2 = 90 mph
directions of trains = towards each other
Time to meet = 150/(60+90) = 150 miles / 150 mph = 1 hour
Speed of fly = 120 mph
Since fly has been flying for one hour, it travelled 120 miles.
Answer:
x = -2 and x = 5/4
Step-by-step explanation:
The image below shows step-by-step on how to solve it.
Hope this helps! :)
To answer this question, we first have to set up an equation with variables.
We can use "x" to represent the cost of each bracelet.
Equation: number of bracelets bought × cost of each bracelet = total cost
Number of bracelets bought: 7
Total Cost: 49
Using this information, we can fill in the equation and solve for x.
7x = 49
To isolate x, divide both sides by 7.
x = 7
Since x equals 7, we now know that each bracelet cost $7.
