Stephen, Gavin and Jim share some sweets in the ratio 1:4:4. Stephen gets
13 sweets. How many more sweets does Gavin get over Stephen?
Answer:
39 sweets
Step-by-step explanation:
the sum of the ratio is
1+4+4= 9
to find the number of sweets shared we say
1/9*X=13 sweets
X=9*13
X=117
therefore Gavin and jim will share equal number of sweets
117-13
104 sweets. Jim gets 52 while Gavin gets 52 sweets.
How many more sweets does Gavin get over Stephen?
52-13
Gavin get 39 more sweets over Stephen. I hope that helps

Answer:
y = 4x +3
Step-by-step explanation:
The slope formula can be used to find the slope:
m = (y2 -y1)/(x2 -x1)
Using the first two lines of the table, we find the slope to be ...
m = (11 -7)/(2 -1) = 4/1 = 4
__
The y-intercept can be found from the relation ...
b = y -mx
Using the slope we found, and the first line of the table, we find the intercept to be ...
b = 7 -4(1) = 3
__
Then the equation is ...
y = mx +b . . . . . . slope-intercept form of the equation for a line
y = 4x +3

Step-by-step explanation:
Factor the equation below.
f(x) = x2 + x - 20
Answer:
f(x) = (x+5)(x-4)
Step-by-step explanation:
Key skills used in this problem: Quadratic equations, factoring
1) The equation x^2 + x - 20 is factorable (meaning it can be facttored easily)
2) We need to find factors of -20 that add up to 1. This is because our ac (a term times the c term) is -20 and our b term (the coefficient for +x) is 1.
3) The two factors would be 5 and -4.
4) So it would be (x + 5)(x - 4) when factored
Hope you understood and have a nice day!! :D
Answer:
f(x)= (x+5)(x-4)
Step-by-step explanation:
First muliply the coefficient of the xsquared with the constant, in this case 1 × -20 = -20. Then figure out two factors of -20 that equal the coefficient of the stand-alone x when added together. In this case, that coefficient is 1. Factors of -20 that add to 1 are 5 and -4. Now simply take each of those numbers and shove them into parenthesis with an x.

6
Answer: x = 5
Step-by-step explanation:To solve this you first need to collect the like terms 6x-2x=7+3. Add those 4x=20. After that you need to divide both sides. Then you will get you solution.
Answer:
Step-by-step explanation:
6x−13=2x+7
Inverse operation:
6x into a negative then subtract it by 2x
2x - 6x = -4
Change 7 into a negative then subtract it by -13
-13 - 7 = -20
-20 = -4x
Divide:
-20 = -4x

The power of 2 in 400! is 397.
What is the method of determination of power of prime in Factorial ?Let p is the prime number whose power is to be found
Let n is the factorial number then
p in n! = (n /p) + (n/p²) +(n/p³) + .......
until Numerator < Denominator
and after division only the integer part is taken
Therefore to determine the power of 2 in 400!
2 in 400! = (400 /2) + ( 400 /2²) + (400 /2³) +(400 /2⁴) +(400 /2⁵) +(400 /2⁶) +(400 /2⁷) +(400 /2⁸) + above this N < D
2 in 400! = 200 +100 +50+25+12+6+3+1
2 in 400 = 397
Therefore the power of 2 in 400! is 397.

3c-5-4c=-15 solve for c
Answer:
c=10
Step-by-step explanation:
First combine like terms by doing 3c-4c to get -1c-5=-15. Then add 5 to both sides to get -1c=-10. Then divide by -1 on both sides to get c = 10

On what interval(s) of x is f(x) positive?
On what interval(s) of x is f(x) negative?
Answer:
Positive: (-2,1)
Negative: (-∞,-2) U (1,∞)
Step-by-step explanation:
The graph of the function f(x) is given in the figure. We can see some points like (-2,0), (-1,1), (2,-2), and many others.
Note the second value of each point (the value of y) is positive or negative. When it's positive, the graph is above the x-axis, when it's negative, the graph is below the x-axis. When it's 0, the graph crosses the x-axis.
To find the intervals of x where the function is positive, we only have to look into the zone where the graph is above the x-axis. It can be identified as the interval (-2,1).
Similarly, the function is negative in the interval (-∞,-2) U (1,∞)
The function f(x) is positive in the interval [-2, 1].
The function f(x) is negative the interval (-∞, -2) U (1, ∞).
The positive regions of a function f(x) are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero).
To find the intervals of x where the function is positive,
In the interval [-2, 1] , the function f(x) is positive.
The negative regions of a function f(x) are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).
In the interval (-∞,-2) U (1,∞) , the function f(x) is negative.
y-values that are on the x-axis are neither positive nor negative. The x-axis is where y = 0.
when y = 0, x = -2, 1
Therefore, the function f(x) is positive in the interval [-2, 1] and negative in the interval (-∞,-2) U (1,∞).
