Which expression is equivalent to 12a + 8?
4(3a + 2)
4(3a + 8)
6(6a + 2)
6(6a + 8)
Answer:
4(3a+2)
Step-by-step explanation:
Since 4 is on the outside of the parenthesis, you have to multiple everything inside of the parenthesis by 4 which would leave you with 12a+8 which is the exact same as the expression in the question
Answer:
4(3a + 2)
Step-by-step explanation:
apply the rule a(b+c) = ab+ac

Answer:
-23 :)
Step-by-step explanation:
Answer:
Step-by-step explanation:
What you would need to do is take 9+14, and you would get 23, and you would want to change that to be negative, so you would get a negative answer. So now when you plug the -23 into the empty space it is -23+ 14= -9

Wendy has 10 ½ pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 1 ¼ pounds. How many containers does she need? Show your work and answer in a complete sentence.
Answer:
9 containers
Step-by-step explanation:
Since Wendy wants to divide the 10 [tex]\frac{1}{2}[/tex] pounds of the potato salad into 1 [tex]\frac{1}{4}[/tex] pounds for each container, You just divide 10 [tex]\frac{1}{2}[/tex] by 1 [tex]\frac{1}{4}[/tex] using the following method:
Convert 10 [tex]\frac{1}{2}[/tex] into an improper fraction:
[tex]\frac{21}{2}[/tex]
Convert 1 [tex]\frac{1}{4}[/tex] into an improper fraction:
[tex]\frac{5}{4}[/tex]
Then finally divide [tex]\frac{21}{2}[/tex] by [tex]\frac{5}{4}[/tex] :
[tex]\frac{21}{2}[/tex] ÷ [tex]\frac{5}{4}[/tex]
This is the same as [tex]\frac{21}{2}[/tex] times the reciprocal of [tex]\frac{5}{4}[/tex]:
[tex]\frac{21}{2}[/tex] × [tex]\frac{4}{5}[/tex] = [tex]\frac{42}{5}[/tex] = 8.4
Since we cannot have 8.4 containers, we round it up to 9 containers, because for 8 containers, there will still be some pounds of potato salad left.

The graph shows the number of quarts picked and the amount of money the customer paid.
Another customer pays $8.75 for the strawberries she picks. What point (n, a) on the graph represents this?
Answer:
$3.50 for 1 quart
Step-by-step explanation:
Point (n, a) on the graph represents the number of quarts and the Amount paid(in $).
What is the importance of graphs in our daily life?Graphs are a popular tool for visually illuminating data relationships. A graph serves the objective of presenting data that are either too many or complex to be fully expressed in the text while taking up less room.
Given, The graph shows the number of quarts picked and the amount of money the customer paid. Another customer pays $8.75 for the strawberries she picks.
Slope of the given graph = y₂ - y₁ / x₂ - x₁
Slope of the given graph = 3.5-0 /1-0 = 3.5
As the Graph is passing through the origin point
Hence, the equation of the line will be y = mx
Where slope(m) = 3.5
thus the equation of the given graph y = 3.5 x
For another customer given, y = 8.75
Hence x = 8.75/3.5
x = 2.5
Coordinates over the graph will be(2.5, 8.75)
Therefore, The number of quarts and the amount paid (in dollars) are represented by the graph's points (n, a).

Step-by-step explanation:
Yes, repeating decimals can be made into fractions, and in fact are racial numbers.
Answer:
Enrique is correct. Repeating decimals are rational numbers because they can be written as fractions. The number is actually equivalent to 4/9. (I think)

Answer:
d=13
Step-by-step explanation:
Calculate the distance between 2 points in 2 dimensional space.
Enter 2 sets of coordinates in the x y-plane of the 2 dimensional Cartesian coordinate system, (X1, Y1) and (X2, Y2), to get the distance formula calculation for the 2 points and calculate distance between the 2 points.
Accepts positive or negative integers and decimals. (6 and/or 6.5)
Distance Formula:
The distance between two points is the length of the path connecting them. The shortest path distance is a straight line. In a 2 dimensional plane, the distance between points (X1, Y1) and (X2, Y2) is given by the Pythagorean theorem:
d=(x2−x1)2+(y2−y1)2−−−−−−−−−−−−−−−−−−√
Calculate Distance
To calculate the distance between 2 points, (X1, Y1) and (X2, Y2), for example, (5, 6) and (-7,11), we plug our values into the distance formula:
d=(−7−5)2+(11−6)2−−−−−−−−−−−−−−−−−√
combining terms inside parentheses we get:
d=(−12)2+(5)2−−−−−−−−−−−√
squaring both terms we get,
d=144+25−−−−−−−√
adding the 2 results,
d=169−−−√
finally,
d=13

Step-by-step explanation:
Write the number 4 2/3 as an improper fraction.
The improper fraction 14/3.
To convert the mixed number 4 2/3 to an improper fraction, we need to find the equivalent fraction where the whole number and fraction parts are combined.
Step 1: Multiply the whole number (4) by the denominator of the fraction (3):
4 * 3 = 12
Step 2: Add the product from Step 1 to the numerator of the fraction (2):
12 + 2 = 14
Step 3: Write the result from Step 2 as the numerator, keeping the same denominator (3):
The improper fraction is 14/3.
Therefore, the mixed number 4 2/3 can be expressed as the improper fraction 14/3.
To understand the result, imagine dividing a whole into 3 equal parts. With 4 wholes, you have 12 parts (4 * 3 = 12). Adding the 2 extra parts (2/3) gives a total of 14 parts out of 3 wholes, which is represented by the improper fraction 14/3.
