What is the solution to the inequality?
-2/3 (2x - 1/2)<= 1/5x - 1
-2/3(2x-1/2) ≤1/5x-1
Simplify the left side:
-4/3x+1/3 ≤1/5x-1
Subtract 1/5x from each side:
-23/15x + 1/3≤-1
Subtract 1/3 from each side:
-23/15x ≤-4/3
Divide both sides by -23/15:
X = -4/3 / -23/15
X ≥ 20/23

abigail has 16 shoes use repeated subtraction to show how many pairs of shoes Abigail has
Hello!
Here is how we solve this question.
We know that 2 shoes = 1 pair
So we subtract 2 from 16 until we reach 0, and count how many times we subtracted.
16-2=14
14-2=12
12-2=10
10-2=8
8-2=6
6-2=4
4-2=2
2-2=0
After we do repeated subtraction we find that Abigail has 8 pairs of shoes!
Hope this helps you with your question.
Since shoes comes in pairs, then the number of shoes Abigael has would be obtained by subtracting 2 from 16 until we obtain 0. Hence, the number of shoes she has is 8.
The total number of shoes = 16
Shoes are in pairs ; Hence 1 pair of shoe = 2 shoes
Using repeated subtraction :
1 ; 16 - 2 = 14
2 ; 14 - 2 = 12
3; 12 - 2 = 10
4; 10 - 2 = 8
5; 8 - 2 = 6
6; 6 - 2 = 4
7; 4 - 2 = 2
8; 2 - 2 = 0
Therefore, the Number of shoes Abigael has is 8

which of the following are functions
A. [(-2,3)], [(-1,5)], [(0,7)], [(1,9)]
B. [(-3,3)], [(3,3)], [(0,0)], [(1,1)], [(-1,1)]
C. [(-2,5)], [(-1,4)], [(0,3)], [(-1,2)], [(-2,1)]
Both A and B represent functions, as the same x value is not used twice.
However, with option C, the x value -2 is used twice, and thus it is not a function.
The concept of functions in mathematics is determined by whether each input (or 'x' value) corresponds to exactly one output (or 'y' value). Upon examination, the sets of ordered pairs in option A qualify as functions, while the sets in options B and C do not.
Explanation:A function in Mathematics is a relation between a set of inputs and a set of outputs where each input is related to exactly one output. In your question, you have three different sets of ordered pairs. Let's examine them.
A. [(-2,3)], [(-1,5)], [(0,7)], [(1,9)]
Here every 'x' value is paired with only one 'y' value, so this one is a function.
B. [(-3,3)], [(3,3)], [(0,0)], [(1,1)], [(-1,1)]
For this one, we see that 'x' values -1 and 1 are both paired with 'y' value 1. This implies that a single 'x' value has more than one 'y' value which is not allowed for a function. So this one is not a function.
C. [(-2,5)], [(-1,4)], [(0,3)], [(-1,2)], [(-2,1)]
This one is similar to the second case where 'x' values -1 and -2 are both paired with multiple 'y' values. So, this one is not a function either.
So, only the first set constitutes a function.

a wallet containing 5 five-dollar bills, 7 ten-dollar bills, and 8 twenty-dollar bills Is found and returned to its owner. the wallets owner will reward the finder with 1 bill drawn randomly from the wallet. what is the probability that the bill drawn will be a twenty-dollar bill?
The formula for probability is [tex]\frac{number of ideal outcomes}{number of possible outcomes}[/tex]. Because there are 8 $20 bills, there are 8 ideal outcomes and 20 possible outcomes. THis gives us [tex]\frac{8}{20}[/tex] which can be simplified to [tex]\frac{2}{5}[/tex].
The answer is 2/5 or 0.4 or 40%.
Answer:
2/5
Explanation:
There are 5+7+8 = 20 total bills.
Out of these, 8 are twenty-dollar bills.
The probability of choosing 1 twenty-dollar bill is then 8/20, which simplifies to 2/5.
1). Solve for x 3x-6=7x+18
2) Simplify the expression
65-4^2 (10-2)+37
Please show the work for both.
1) The solution of expression is, x = - 6
2) The solution is, - 26
We have to give that,
1) An expression is,
3x - 6 = 7x + 18
2) An expression,
65 - 4² (10 - 2) + 37
Now, Simplify the expressions as,
1) 3x - 6 = 7x + 18
Add 6 on both sides,
3x - 6 + 6 = 7x + 18 + 6
3x = 7x + 24
Subtract 7x on both sides,
3x - 7x = 24
- 4x = 24
Divide both sides by - 4,
x = - 24/4
x = - 6
Hence, Solution is, x = - 6
2) 65 - 4² (10 - 2) + 37
Apply the BODMAS rule,
65 - 16 (8) + 37
65 - 128 + 37
65 + 37 - 128
102 - 128

The question is asking for a decimal number between 200 and 300 with '7' in the thousandths place and '2' in the hundredths place. One possible answer is 250.027, but other variations exist based on the whole number part as long as it is between 200 and 300.
Explanation:The student's question is asking for a specific decimal number between 200 and 300. The conditions set are that the number should have '7' in the thousandths place, and '2' in the hundredths place. Since there are no conditions for the other places, these digits could be any whole number.
One possible answer could be 250.027. We have '2' in the hundredths place (right after the decimal point), '7' in the thousandths place (two spots after the decimal point), and the whole number part is between 200 and 300. Other possibilities exist too, like 267.327 or 280.217.

−4
The slope of a graph is the rate of change of the graph
The slope of the graph is that passes through (0,2) and (1,-2) is (d) -4
Start by selecting any two points on the line of the graph
[tex](x_1,y_1) = (0,2)[/tex]
[tex](x_2,y_2) = (1,-2)[/tex]
The slope (m) of the graph is simply the average rate of change of the graph.
It is calculated as follows:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute values for x and y
[tex]m = \frac{-2-2}{1 - 0}[/tex]
Simplify
[tex]m = \frac{-4}{1}[/tex]

x = 174 (which is the smallest consec multiple of 6)
174 is answer.
Given that sum of 5 consecutive multiples of 6 is 930
To find the smallest multiple
The consecutive multiples of 6 would be of the form
6(k-2), 6(k-1), 6k, 6(k+1), 6(k+2) for some natural number k.
The sum would be
6(k-2)+ 6(k-1)+ 6k+ 6(k+1)+ 6(k+2)= 6(5k) = 930
Divide by 30
k = 930/30 = 31

How is subtracting integers related to adding integers
We can use the number line as a model to help us visualize adding and subtracting of signed integers. Just think of addition and subtraction as directions on the number line. There are also several rules and properties that define how to perform these basic operations.
To add integers having the same sign, keep the same sign and add the absolute value of each number.
To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest.
Subtract an integer by adding its opposite.

Francis heard that a car stereo system was on sale for 30% off. If the sale price was 57.75, what was the original price of the stereo?
Answer:
$82.5
Step-by-step explanation:
We can calculate it with a direct rule of 3. As it has a 30% off, the remaining price is the 70% and we want to know how much is the 100%
[tex]70\% -\!\!\!-\!\!\!- \$57.75\\ 100\% -\!\!\!-\!\!\!- \$ x[/tex]
We use the formula of the direct rule of 3:
[tex]x = \frac {100/100*57.75}{70/100} \\ \\ x = \frac {57.75}{70/100}\\ x = 57.75 * 100/70[/tex]
x = 82.5
The original price of the stereo was $82.5
The original price of the stereo is 82.5
Since the car stereo system was on sale for 30% off, this means that it was sold for 100% - 30% = 70% of the original price.
Let the original price be represented by x
Therefore, 70% of x will be 57.75
70/100 × x = 57.75
0.7 × x = 57.75
0.7x = 57.75
Divide both side by 0.7
0.7x/0.7 = 57.75/0.7
x = 82.5
The original price of the stereo is 82.5
