No
Step-by-step explanation:
10/18 does not equal 45/18
An example of a proportional number is:
4/5 and 8/10
Both numbers are multiplied by 2 making them proportional
10/18 and 45/18 are not proportional

4. At a deli counter,
• Someone bought 1 pounds of ham for $14.50.
• Someone bought 23 pounds of turkey for $25.25.
• Someone bought i pounds of roast beef for $5.50.
Which meat is the least expensive per pound? Which meat is the most expensive per
pound? Explain how you know.
Answer:
1. Which meat is the least expensive per pound? HAM
2. Which meat is the most expensive per pound? ROAST BEEF
Step-by-step explanation:
I know this because when fractions look smaller people think it's actually a smaller portion but it's actually the bigger number.
HOPE THIS HELPED! <33 .
Answer:The least expensive per pound is ham. and the most expensive is the roast beef.
Step-by-step explanation:
Ham: ($14.50)/(1 3/4 lb) = $14.50/(1.75 lb) = $8.29/lb
Turkey: ($26.25)/(2 1/2 lb) = $26.25/(2.5 lb) = $10.50/lb
Roast beef: ($5.50)/(3/8 lb) = $5.50/(0.375 lb) = $14.67/lb
The least expensive per pound is ham.
The graph of linear function k passes through the points(-7,0) and (1,8). Which statement must be true
Answers
The slope of the graph of k is -4/3.
The graph of k passes through the point (-1,-8).
The zero of k is 7
The x-intercept of the graph of k is -7.
Answer:
✅The x-intercept of the graph of k is -7.
Step-by-sep explanation:
Graph the equation of the line that passes through the points, (-7, 0) and (1, 8) by first generating an equation, and then using the equation of the function to plot the graph.
To find the equation, we need to calculate the slope, m, and y-intercept, b.
✅Using points (-7, 0) and (1, 8), the slope of the line is:
[tex] m = \frac{y_2 - y_1}{x_2 -x_1} = \frac{8 - 0}{1 -(-7)} = \frac{8}{8} = 1 [/tex]
Substitute x = 1, y = 8, m = 1 into [tex] f(x) = mx + b [/tex] to find the y-intercept, b, of the function. (Note: f(x) is same as variable y).
[tex] 8 = 1(1) + b [/tex]
[tex] 8 = 1 + b [/tex]
Subtract 1 from each side
[tex] 8 - 1 = b [/tex]
[tex] 7 = b [/tex]
[tex] b = 7 [/tex]
Substitute m = 1 and b = 7 into [tex] f(x) = mx + b [/tex]
The equation of the function is:
[tex] f(x) = (1)x + 7 [/tex]
[tex] f(x) = x + 7 [/tex]
The graph of the function, k, is shown in the attachment below.
❌Now, we know that the slope of the function, m, is 1. Therefore, option A is not correct.
We also know that the graph of the function, k, does not pass through the points (-1, -8). We can confirm this looking at the graph. ❌The point (-1, -8) is not on the line of the graph. Therefore, option B is not correct.
❌The zero of k, is the value of x for which the function, f(x) or y = 0. From our graph, y = 0, when x = -7. This can also be referred to as the x-intercept. The zero of k is -7, not 7.
Therefore, option C is not correct.
✅The x-intercept is where the line of the function of intercepts the x-axis. From our graph, the line intercepts the x-axis at x = -7.
So, the x-intercept of the graph of k is -7.
Therefore, option D is the only statement that is TRUE.
4. Triangle HEF is the image of triangle FGH after a 180 degree rotation about point K. Select all statements that must be true.
a. Triangle FGJ is congruent to triangle FEH.
b. Triangle EFH is congruent to triangle GFH.
c. Angle KHE is congruent to angle KFG.
d.Angle GHK is congruent to angle KHE.
e. Segment EH is congruent to segment FG.
f. Segment GH is congruent to segment EF.
Answer: C, E, F
Step-by-step explanation: dude tbh idek but ik that it’s the right answer
The true statements are:
Angle KHE is congruent to angle KFG.Segment EH is congruent to segment FGSegment GH is congruent to segment EF.Given:
Triangle HEF is the image of triangle FGH after a 180-degree rotation about point KAnd Six statementsTo find:
The true statements out of given sic statements.
Solution:
ΔHEF is the image of ΔFGH after a 180°rotation about point K.
This simply implies that ΔFGH is congruent to ΔHEF. As no dilation is done while rotation of the ΔFGH.
In congruent ΔFGH and ΔHEF
HF = HF (common)GH = EFFG = EH∠FGH=∠HEF∠GFH=∠EHFCan also be written as:
⇒ ∠KFG=∠KHE
∠GHF=∠EFHCan also be written as:
⇒ ∠GHK=∠EFK
So, from the given statements the true statements are:
Angle KHE is congruent to angle KFG.Segment EH is congruent to segment FGSegment GH is congruent to segment EF.Learn more about the congruency of triangles here:

what is the slope of (12,22) (-20,19)
Answer:
3/32
Step-by-step explanation:
The slope is found by
m = ( y2-y1)/(x2-x1)
= ( 19-22)/(-20-12)
= -3/-32
= 3/32

6. Determine the value of x and y in the diagram below.
Show how you determined the value of x and y using Algebra
Answer:
y=43
X=34
Step-by-step explanation:
a) 2y+4=90
2y+4-4=90-4
2y=86. divide 86 by 2 to get y.
b) 3x-11=90
3x-11+11=90+11
3x=101. divide 101 by 3 to get X.

Step-by-step explanation:
Answer:
2 x 10^16
Step-by-step explanation:
1.3 x 10^-4 x n = 2.6 x 10^12
(1.3 x 10^-4 /1.3 x 10^-4) x n = 2.6 x 10^12/1.3 x 10^-4
n = 2 x 10^16
When dividing, subtract your exponents.

Sara and Sage are making hot cocoa. The tables below show the recipes each one used. Which recipe has the strongest chocolate flavor?
Which list contains all of the factors of the number 48? (1 point)
O1, 2, 3, 4, 6, 8, 12, 16, 24
O2, 3, 4, 6, 8, 12, 16, 24, 48
O1, 2, 3, 4, 6, 8, 12, 16, 24, 48
O1, 2, 3, 4, 6, 8, 9, 12, 16, 24. 48
Answer:
1,2,3,4,6,8,12,24,48.
Step-by-step explanation:
To Find A Factor Of A Number You'll Need To Find Two numbers by which you multiply to get the number you're looking for.SO TO FIND THE FACTOR OF 48 YOU WILL NEED TO FIND TWO NUMBERS THAT CAN MULTIPLY EACH OTHER AND GIVE A PRODUCT OF 48
1×48=48(Any number multiplied by 1 is the number itself and 1 multiplied by 48 is 48 so it makes it a factor)
2×24=48(Here you can clearly see that when 2 is multiplied by 24 the product is 48 so 2 and 24 becomes a factor of 48)
3×16=48(So getting the product 48 by multiplying 3 and 16 3 and 16 becomes a factor of 48)
4×12=48(You can see that when you multiply 4 by 12 the product is 48 so 4 and 12 becomes a factor of 48)
5×?=48(You can't get any number to multiply by 5 to get 48 so the number 5 is not a factor of 48)
6×8=48(With this you can see that when 6 is multiplied by 8 its product is 48 so it becomes a factor of 48)
So The Factors We Got After We Multiplied The Two Numbers Are As Follows;
1 and 48
2 and 24
3 and 16
4 and 12
So the above numbers becomes the factor of 48
So the factors of 48 are: 1,2,3,4,6,8,12,24,48.

Given:15y+7=12-20y prove:y=1/7 (I just need the prove thanks)
Answer:
15y+7=12-20y (add 20y to both sides)
35y+7=12 (minus 7 from both sides)
35y = 5 (divide both sides by 35) (5/35=1/7)
y= 1/7
Answer:
64/7 = 64/7 yes y = 1/7
Step-by-step explanation:
To prove this we simply have to plug in!
15(1/7) + 7 = 12 - 20(1/7) (simplify)
15/7 + 7 = 12 - 20/7 (simplify further)
64/7 = 64/7
So yes y = 1/7

Consider the equation: 3x + 1 – 9 = 3(x + 2) + n.
Give a value of n so that the equation has no solutions.
Explain why you are correct.
answer: n = -14
3x + 1 - 9 = 3(x + 2) + n
<=> 3x - 8 = 3x + 6 + n
<=> 3x - 8 - 3x - 6 = n
<=> n = -14
