Larry and Steve have 171 marbles in all. The number of marbles Larry has is 39 fewer than 3/7 of the number of marbles Steve has. How many marbles does Steve have?
Answers
Total marbles = 171 = steves + lary’s
X + 3x/7 – 39 = 171
X + 3x/7 = 171 + 39
10x/7 = 210
10x = 210 * 7
10x = 1470 X = 147
Larry = 3/7(147) – 39
Larry = 63 – 39 = 24
Steve = 147
Total marbles = 147 + 24 = 171

Subtract cos(x) from each side:
sin(x) = -cos(x)
Divide each side by cos(x) :
sin(x) / cos(x) = -1
But sin/cos = tangent
tan(x) = -1
x = 135° and 315°
x = 3/4 pi radians and 7/4 pi radians

54 is the average of the two numbers 36 and 72.
What is Statistics?
Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
We need to find the average of the two numbers 36 and 72.
The average (A) of two number, M and N, is given by the formula A=m+n/2
Let m = 36
n=72
Now to find the average of two numbers we have to plug in these values in the formula
A=36+72/2
=108/2
=54
Hence, 54 is the average of the two numbers 36 and 72.

does the function represent growth or decay?
By what percentage does the population change each year?
Answers
Answer:
- 280
- function represent growth.
- 29 %
Step-by-step explanation:
Equation to calculate population size after time, t
P(t) = 280(1.29)^t
To find initial population size we will take t = 0
P(0) = 280(1.29)^0
= 280(1)
= 280
To find that function represent growth or decay
P(1) = 280(1.29)^1
= 280(1.29)
= 361.2
Its means that after a year population increases. Hence, function represent growth.
By what percentage does the population change each year?
(361.2 - 280 / 280) * 100%
= 29 %
Answer:
280
function represent growth.
29 %

Answer:
NO Solution
Step-by-step explanation:
First, from the first equation let's move the Y term to the other side to match with the second equation.
Now lets compare the two equations.
Since the left sides are the same but the right sides of the equations aren't, we can see there are no solutions to this system.
