Jeff Lytle can buy mulch for $2.39 a bag at the gas station. He can get six bags of the same mulch at the garden store for $15.00, or nine bags for $19.00. Which is the best buy?
nine bags for $19.00 is the best buy.
Answer:
Step-by-step explanation:
1 bag / $2.39 = $2.39
6 bags / $15.00 = $2.50 best buy is 9 bags
9 bags / $19.00 = $2.11

Write the standard form of each equation.
0=-x+y+3
Answer:
y = x - 3
Step-by-step explanation:
Linear equations are most often written in the form y = mx + b, where m is the slope of the line.
Here, 0=-x+y+3 can be re-written as x - 3 = y, or y = x - 3. Here the slope is 1 and the y-intercept is (0, -3).
Please help with answer solution clearly shown--thx!
Answer:
Step-by-step explanation:
First you have to multiply both sides by 4
4 (3x - 1) by 4 > 3 x 4
Then simplify it:
3x-1 > 12
Now add one to both sides
3x - 1 + 1 > 12 + 1
Then simplify it again:
3x > 13
Now divide both sides by 3
3x ÷ 3 > 13 ÷ 3
Answer:
x = 13 ÷ 3
To eliminate the x terms and solve for y in the fewest steps, by which constants should the equations be multiplied
by before adding the equations together?
First equation: 6x-5y=17
Second equation: 7x + 3y = 11
The first equation should be multiplied by 3 and the second equation by -5.
O The first equation should be multiplied by 3 and the second equation by 5.
O The first equation should be multiplied by 7 and the second equation by -6.
The first equation should be multiplied by 7 and the second equation by 6.
Based on the equation, to eliminate the x terms and solve for y in the fewest steps; the first equation should be multiplied by 3 and the second equation by 5.
Simultaneous equation6x - 5y = 17
7x + 3y = 11
Using elimination method
Multiply equation (1) by 3 and (2) by 518x - 15y = 51
35x + 15y = 55
Add the equation18x + 35x = 51 + 55
53x = 106
x = 106/53
x = 2
Substitute x = 2 into6x - 5y = 17
6(2) - 5y = 17
12 - 5y = 17
-5y = 17 - 12
-5y = 5
y = 5/-5
y = -1
Therefore, the solution to the simultaneous equation; 6x - 5y = 17, 7x + 3y = 11 is x = 2 and y = -1

the perimeter of a triangle is represented by 3x² +8x-9. Two of its sides are represented by (x²+11x+5) and (-2x²-4x+2) What expression would represented the third side
Answer:
The third side has a length of 4x² + x - 16
Step-by-step explanation:
We can solve this by taking the value given for the perimeter, and subtracting the values of the other two sides:
3x² + 8x - 9 - (x² + 11x + 5) - (-2x² - 4x + 2)
= 3x² + 8x - 9 - x² - 11x - 5 + 2x² + 4x - 2
= (3 - 1 + 2)x² + (8 - 11 + 4)x - (9 + 5 + 2)
= 4x² + x - 16

195 students went on a field trip, 21 students rode in cars and the rest of the students filled
six buses. How many students were in each bus?
Step-by-step explanation:
let x represent the bus
6x + 21 = 195
6x = 195 - 21
6x =174
x = 29
Answer:
29 students in each bus
Step-by-step explanation:
at first, 21 students rode by car. so the remaining students are 195-21=174 students.
Now if we divide the remaining number of students by the number of buses then,
[tex] \frac{174}{6} = 29[/tex]
which is 29 students in each bus.

The values of x and y are directly and one pair of values are given.
write an equation that relates x and y. simplify completely.
x= -4, y =6
Answer:
The relation is [tex]y = -1.5x[/tex]
Step-by-step explanation:
x and y are directly proportional:
This means that the equation is given by:
[tex]y = ax[/tex]
In which a is the multiplier that relates these two variables.
x= -4, y =6
We use this to find a. So
[tex]y = ax[/tex]
[tex]6 = -4a[/tex]
[tex]a = -frac{6}{4}[/tex]
[tex]a = -1.5[/tex]
So
The relation is [tex]y = -1.5x[/tex]

Both weights vary according to a Normal distribution.
7.) If you randomly selected one adult woman, what is the probability that her weight exceeds (is higher than) 130 pounds?
Suppose you randomly selected one adult male and one adult female from the entire U.S. population. Let the variable D = the difference in their weights (male – female).
8.) Calculate and interpret the mean of D.

c=6+5
c=11

Hope this helps! :)
Answer: B. (5,11)
Step-by-step explanation:
c = 6 + 1s In this case we know that c is your total cost and s is the number of downloaded songs.
If we were to do it in terms of x and y, y will be c, and x will be s.
Now is asking for the cost of 5 songs, so you will input the value 5 into the equation for s and solve for c.
c = 6 + 1(5)
c = 6 + 5
c = 11
Now we know that for 5 songs it will cost you $11, and if x is the same as the number of songs, and y is the total cost then we can say that the point will be,

Draw a balanced hanger diagram for the equation 2x=4
Step-by-step explanation:
3360832553 ____ pass___ wZE2XQ
Answer:
See the attached picture.
Step-by-step explanation:
I had to look up 'balanced hanger' because that was not a term from my own math education, but I found it no problem.
See the attached picture.
There are 2 x's on the left and 4 1's on the right.
This means the equation has 2 x's on the left of the equal sign and 4 1's on the right.
Each unit of different size should be in a different shape.
The idea is that the hanger 'balances', just like a set of scales, or the same way an equation balances both sides.
Hope this helps.
