The cost of 3 loaves of bread and 3 gallons of milk is $19.35. The cost of 4
loaves of bread and 2 gallons of milk is $17.90. How much does one loaf
of bread cost?
Answer:
bread $2.5 milk $3.95
Step-by-step explanation:
b=bread m= milk
3b +3m = 19.35
4b+2m= 17.90
Multiply the first by (-2)
Multiply the second by 3
Then add both
-6b -6m = -38.7
12b+6m=53.7
(when you add both 6m is cancelled)
6b = 15
b= 2.5 (BREAD $2.5)
4(2.5) = 10
10+ 2m = 17.90
2m = 7.90
m= 3.95 (MILK $3.95)
Hunter is making $46,500 per year and gets a 5.5%
increase in pay. Determine how much money
Munter makes after his increase and show your
work
Answer:
$49,057.50
Step-by-step explanation:
To find how much a percent is of a number you multiply that number and that percent then add the two
SO.... 46,500x5.5% is 2557.50 and then you add the 2 so 46,500 + 2557.50= 49,057.50 hope this helps
Can someone pls help? The stuff in the box is n’t right. Please help!
Answer:
fixed amount is 150
the rate is 6
The formula to calculate the total cost of the caterer is
total cost = 150 × 6 + number of students
Step-by-step explanation:
1. 1050= 150×r+f
2. 750= 100×r+f
• On number 2 you substract on both sides f so you get 750-f=100×r with this you divide on both sides 100 and you get 7,50 -f÷100=r
• Now you can put r into term of number 1 and you get 1050=150x(7,50-f÷100)+f
• If you calculate this to just get a f on one side you get f=150 so this the fixed amount
• Put f in r=7,50-f÷100 so u get r=7,50-150÷100 or r=6 this the rate
• So the formula to calculate the total cost for the caterer is
total cost=150 + 6 × number of students

1: Explain why the equation (x-4)^2-17=8 has two solutions. Then solve the equation to find the solutions. Show your work.
2: This is Josh’s solution for the equation x^2+4x+3=0:
x^2+4x+3=0
x^2+4x=-3
x^2+4x+4=-3+4
(x+2)^2=1
x+2=1
x=-1
Is Josh’s solution correct? Explain.
3:Use the quadratic formula to solve x^2-6x+7. Show your work. Then describe the solution. No work, no credit.
Answer:
1
the equation (x-4)^2-17=8 has two solutions because it is in a quadratic form.
(x-4)^2-17=8
x²-8x+16-17-8=0
x²-8x-9=0
Doing middle term factorization
x²-9x+x-9=0
x(x-9)+1(x-9)=0
(x-9)(x+1)=0
either
x=9
x=9or
x=9orx=-1
2.
x^2+4x+3=0:
Doing middle term factorization
x²+3x+x+3=0
x(x+3)+1(x+3)=0
(x+3)(x+1)=0
either
x=-3
or
x=-1
Josh’s solution is incorrect because he missed x=-3.
3.
x^2-6x+7=0
By using quadratic equation formula:
Comparing above equation with ax²+bx+c=0
we get
a=1
b=-6
c=7
Now
we have
x=[tex] \frac{ - b ± \sqrt{ {b}^{2} - 4ac} }{2a} [/tex]
x=[tex] \frac{ 6± \sqrt{ {-6}^{2} - 4*1*7} }{2} [/tex]
x=[tex] \frac{ 6±2\sqrt{ 2}}{2} [/tex]
x=[tex] { 3±\sqrt{ 2}} [/tex]
Taking positive
x=[tex] { 3+\sqrt{ 2}} [/tex]
taking negative
x=[tex] { 3-\sqrt{ 2}} [/tex]
What is the next step
Answer:
ABC = 50 degree.
Step-by-step explanation:
You add the bisect angles together to get the whole angle (ABC)
(8x - 7)+(6x+1)
(8(4)-7)+(6(4)+1)
(32-7)+(24+1)
25+25 = 50
Find the slope of the line using the slope formula.
(-1 , 3 ) and ( -1, 0)
Answer:
m=undefined
Step-by-step explanation:
The slope tells us the steepness and direction of a line. It is the change in y over the change in x.
[tex]m= \frac{y_2-y_1}{x_2-x_1}[/tex]
In this formula, (x₁, y₁) and (x₂, y₂) are the points the line passes through.
The points we are given are (-1, 3) and (-1, 0). If we match the number with the corresponding variable we see that:
x₁ = -1 y₁= 3 x₂= -1 y₂ = 0Substitute the values into the formula.
[tex]m= \frac{ 0-3}{-1--1}[/tex]
Solve the numerator.
0-3 = -3[tex]m= \frac{-3}{-1--1}[/tex]
Solve the denominator.
-1--1= -1+1=0[tex]m=\frac{3}{0}[/tex]
Since we cannot divide a number by 0, the slope is undefined. Basically, this is a vertical line and all the points have the same x-coordinate.
function h describes the height of a ball, in inches, after n bounces and is defined by the equation h(n)=120 x (4/5)^n.
What is h(3) ?
What does h(3) represent in this situation?
Answer:
Step-by-step explanation:
h(3) = 120*(4/5)^3, which evaluates to 120(64/125), or 61.64.
What does this mean: After 3 bounces the height of the ball is 61.64 ft.

Find the mean and median of the data. 8 1/2,6 5/8,3 1/8,5 3/4,6 5/8,5 1/4,10 5/8,4 1/2 The mean is . The median is .
Answer:
Median = 6.1875
Mean = 6.375
Step-by-step explanation:
Given the data:
8 1/2,6 5/8,3 1/8,5 3/4,6 5/8,5 1/4,10 5/8,4 1/2
Arranging in ascending order :
3 1/8, 4 1/2, 5 1/4, 5 3/4, 6 5/8, 6 5/8, 8 1/2, 10 5/8
Median = 1/2(n + 1)th term
n = 8
1/2 (9) th term
= 4.5th term
(5 3/4 + 6 5/8) / 2
= 6.1875
Mean = Σx / n
Mean = 51 / 8
Mean = 6.375

Answer:
b and e
Step-by-step explanation:
answers are b, and e. A is incorrect since 30 percent isn't very high, way less than half. c is incorrect since it says 30 if it said 60 then it would correspond with the table. D is incorrect since this is this year, it fluctuates between years so there is no guarantee that the same amount of kids will want to take music. ur welcome...

a.Find the mean, median, and mode of 14, 15, 3, 15, 14, 14, 18, 15, 8, 16
Given:
The data set is:
14, 15, 3, 15, 14, 14, 18, 15, 8, 16
To find:
The mean, median and mode of the given data set.
Solution:
We have,
14, 15, 3, 15, 14, 14, 18, 15, 8, 16
Arrange the data values in ascending order.
3, 8, 14, 14, 14, 15, 15, 15, 16, 18
Mean of the data set is:
[tex]Mean=\dfrac{\text{Sum of all observations}}{\text{Number of observation}}[/tex]
[tex]Mean=\dfrac{3+8+14+14+14+15+15+15+16+18}{10}[/tex]
[tex]Mean=\dfrac{132}{10}[/tex]
[tex]Mean=13.2[/tex]
The number of observation is 10 which is an even number. So, the median of the data set is:
[tex]Median=\dfrac{(\dfrac{n}{2})\text{th term}+(\dfrac{n}{2}+1)\text{th term}}{2}[/tex]
[tex]Median=\dfrac{(\dfrac{10}{2})\text{th term}+(\dfrac{10}{2}+1)\text{th term}}{2}[/tex]
[tex]Median=\dfrac{5\text{th term}+6\text{th term}}{2}[/tex]
[tex]Median=\dfrac{14+15}{2}[/tex]
[tex]Median=\dfrac{29}{2}[/tex]
[tex]Median=14.5[/tex]
Mode is the most frequent value of the data set.
In the given data set the highest frequency is 3 because 14 and 15 occurs three times.
So, the mode of the given data set is 14 and`15.
Therefore, the mean is 13.2, median is 14.5 and mode is 14 and 15.
