Find the missing number so that the equation has infinitely many solutions.
– x + 20 + blank x = – 4 x + 20
Answers
Answer:
-3
Step-by-step explanation:
To make the equation have infinitely many solutions, we need to make both sides equal.
i will use variable y in place of blank
-x + 20 + yx = -4x + 20
-x + yx = -4x
yx = -3x
y = -3
now we can check the answer
-x + 20 - 3x = -4x + 20
-4x + 20 = -4x + 20
0 = 0
this means there are infinitely many solutions

a list on integers has a mode of 32, mean 22 and median m. m iiis one of the numbers on the list.
nvm this isnt the full quesion
Answers
The most appropriate choice for mean, median and mode will be given by-
Value of m = 20
What is mean, median and mode?
Mean of a data set gives the average value of the data set
Mean is calculated by the dividing sum of all observations by the number of observations.
Median is the middle value of the data set when the data set is arranged in ascending or descending order
Mode is the value of the data set which has the highest frequency
Here,
Let the number of integers be n
mean = 22
Sum = 22 x n
= 22n
Now m is replaced by m + 10
New sum = 22n + 10
New mean = 24
New sum = 24n
By the problem,
22n + 10 = 24n
24n - 22n = 10
2n = 10
n = [tex]\frac{10}{2}[/tex]
n = 5
Now mode of 5 numbers = 32
Smallest number = 10
Data set = {10, x, m, 32, 32}
Now , if m is replaced by m - 8, the new median is m - 4
Since 5 is odd, m - 4 is a member of this data set
So x = m-4 (As m- 8 < m - 4, so on replacing m by m-8 will shift m - 8 to second place and x to third place as the data set is arranged in ascending order)
Data set = {10, m-4, m, 32, 32}
Mean = [tex]\frac{10+(m-4)+m+32+32}{5}[/tex]
[tex]22 = \frac{70 + 2m}{5}\\70 + 2m = 22 \times 5\\70 + 2m = 110\\2m = 110 - 70\\2m = 40\\m = \frac{40}{2}\\m = 20[/tex]
Value of m = 20

The digits in the product of 0.48 and a decimal number between 350 and 400 are 182136. explain how to correctly place the decimal point without knowing the other factor. then place the decimal point in the product
Answers
The right way to write digit 182136 without knowing the other factor is by; moving the decimal points 3 places to the left.
What is the explanation for the above?It is given that the digits in the product of 0.48 and a decimal number between 350 and 400 are 182136. Note that 0.48 is simply 48/100.
Hence, consider the decimal number between 350 and 400. The number will include one decimal place, so if it's 350.1, we may express it as 3501/10.
When we multiply 48/100 by 3501/10, the denominator is 1000, which is three decimal points to the left of the result.
As a result, the right method to express the answer supplied to us is 182.136, which was accomplished by shifting the decimal point three spaces to the left.

Answers
Answer:
Step-by-step explanation:
To find the lowest price per ounce, we must find the unit rate (how much does it cost to buy 1 unit of something).
The way to do this is divide the price by the quantity.
Option 1) [tex]\frac{1.65}{26/5} = 1.65 * 5/26 = 8.25/26 = 33/104[/tex]
For the first option, every ounce costs $33/104.
Option 2) [tex]\frac{10.4}{26} = 0.4 = \frac{4}{10}[/tex]
For the second option, every ounce costs $4/10.
Since we know that 33/104 is less than 4/10, option 1 is more worth it as every ounce costs less than option 2.

There are two special powers: "to the second power" is commonly pronounced "squared," and "to the third power" is commonly pronounced "cubed."To find ax, simply multiply a by itself x times. To compute two to the second power, multiply two by itself two times. The exponent of a number indicates how many times the number should be multiplied. The "2" in 8² tells us to multiply 8 twice, so 8² = 8 × 8 = 64.

Answers
If Lamont withdraws $2,750 monthly, he will be 66 years old (after 134.326 months) when the money runs out.
How is the number of monthly withdrawals calculated?We can calculate the number of monthly withdrawals using an online finance calculator.
It determines the number of periods it will take for the investment to be exhausted, given an interest rate of 3.8%.
I/Y (Interest per year) = 3.8%
PV (Present Value) = $300,500
PMT (Periodic Payment) = $-2750
FV (Future Value) = $0
Results:
N = 134.326 months
Years = 11 years (134.326/12)
Age at FV = $0 is 66 years (55 + 11)
Sum of all periodic payments = $-369,397.09 (134.326 x $-2,750)
Total Interest = $68,897.09
Thus, making a monthly withdrawal of $2,750 will exhaust the investment when Lamont turns 66.

A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 8% vinegar, and the second brand contains 13% vinegar. The chef wants to make 230 milliliters of a dressing that is 11% vinegar. How much of each brand should she use?First brand:Second brand:Solve by percent mixture using system of linear equations.
Answers
We have to blend two brands of dressing with different proportions of vinegar. We want to obtain a mix of 230 cubic milimiters with a proportion of 11% of vinegar.
We can call A to the amount of dressing with 8% vinegar and B the amount of dressing with 13% vinegar.
Then, if the volume of the mix is 230 mm³, we can write:
[tex]A+B=230[/tex]We can obtain another equation by looking at the amount of vinegar in the mix.
The amount will be the volume of the mix (230 mm³) times the proportion of vinegar (11% or 0.11 in decimal).
This amount of vinegar will be contributed by the vinegar of each brand. The first brand will contribute with a volume of A times 0.08 and the second brand will contribute with B times 0.13.
We can write this as a equation like this:
[tex]\begin{gathered} 0.08*A+0.13*B=230*0.11 \\ 0.08A+0.13B=25.3 \end{gathered}[/tex]We now have a system of linear equations (two equations and two unknowns).
We can replace B from the second equation by using the first equation:
[tex]\begin{gathered} A+B=230 \\ \Rightarrow B=230-A \end{gathered}[/tex][tex]\begin{gathered} 0.08A+0.13B=25.3 \\ 0.08A+0.13(230-A)=25.3 \\ 0.08A+29.9-0.13A=25.3 \\ (0.08-0.13)A=25.3-29.9 \\ -0.05A=-4.6 \\ A=\frac{4.6}{0.05} \\ A=92 \end{gathered}[/tex]Knowing A = 92 mm³, we can find B as:
