. Joseph tweets 1 3 times a day. Define each variable and write an algebraic expression to describe the number of posts after any given number of days
Given :
Joseph tweets 13 times a day.
To Find :
An algebraic expression to describe the number of posts after any given number of days.
Solution :
Let, number of tweets after x days are y.
Let, the relationship is , y = mx + c.
For, x = 1
13 = m +c ...... 1)
x = 2
26 = 2m + c .......2)
So, m = 13 and c = 0.
Therefore, algebraic expression to describe the number of posts after any given number of days is y = 13x.
Hence, this is the required solution.
help please thanks.

In 2008, Scott Dixon won the Indianapolis 500, completing 500 laps in approximately 3.5 hours. Approximately how long did it take for him to complete 1 lap?
Answer:
0.007 hour or 25.2 seconds
Step-by-step explanation:
From the question, we are told that for Scott Dixon,he completed
500 laps in approximately = 3.5 hours. 1 lap approximately =
Cross Multiply
= 1 lap × 3.5 hours = 500 laps × a hours
a hours = 1 lap × 3.5 hours/500 laps
a hours = 0.007hours
We can convert 0.007 hours to seconds
60 seconds = 1 minute
60 minutes = 1 hour
1 hour = 60 × 60
= 3600 seconds
1 hour = 3600 seconds
0.007 hour =
0.007 hour × 3600 seconds
= 25.2 seconds
Therefore, it took Dixon approximately 0.007 hour or 25.2 seconds did it take for him to complete 1 lap

Rearranging Equations: Solve the equation for y: 8x + y = 14 Solve the equation for x: -9x + 3y = 18
Answer:
y=14-8x
x= -2 + 3y/9x
Step-by-step explanation:
8x+y=14
isolate y so you get:
y=14-8x
-9x+3y=18
isolate x so you get:
-9x=18-3y
divide on both sides to get x by itself
-9x/-9x 18-3y/-9x
x= -2 + 3y/9x
Hope this helps :)
Sonya buys four pairs of shoes on sale for buy one, get one 50% off. The sales tax is 6.5%. If the original price for each pair of shoes was $35, how much does Sonya pay for the four pairs altogether?
Answer:

2 pairs would be original price (35) and 2 would be half off (17.5)
35 + 35 + 17.5 + 17.5= $105
sales tax = 6.5 %
$105 * 6.5 % = 6. 825
$105 + 6.825= 111.825
round up since you cant have 825 cents
$111.83

if a =1 + r + 7r and b = 1 -r ,find an expression that equals A+ 3B in standard form. Answer:
Answer:
A+3B=4+5r
Step-by-step explanation:
Given that,
A = 1+r+7r
B = 1-r
We need to find an expression that is equal to A+3B.
Putting the values of A and B in A+3B, we get :
A+3B = 1+r+7r + 3(1-r)
=1+8r+3-3r
=(1+3) +(8r-3r)
=4+5r
Hence, the values of A+3B equals 4+5r.

Fuji apples cost $3.00 per pound, and Golden Delicious apples cost $2.00 per pound. A childcare center purchases 30 pounds of a combination of the two types of apples for a total of $80. A table titled Apples showing Pounds, Cost per Pound and Total. The first row shows Fuji and has 30 minus g, 3, and x. The second row shows Golden Delicious, and has g, 2, and blank. The third row shows Total, and has 30, blank, 80. Which value could replace x in the table?
Answer:
3(30 - g)
Step-by-step explanation:
# of pounds of Fuji apples = (30 - g)
Cost per pound of Fuji apples = $3 per pound
Total cost of (30 - g) pounds of Fuji apples = 3 * (30 - g)
= 3(30 - g)
Answer:
B. 3(30-g)

Round 97.081 to the nearest tenth
Answer:
97, that's the answer.
Answer: 97.1
Step-by-step explanation: the tenth is the first number after the decimal place so in your question that number is the 0 and the number next to it is 8 so, our 0 needs to change because 8 is bigger than 5 on the number line which makes our 0 increase to 1. You don't need to change the whole number at all.

PLEASE HELP! I’m so confused and i’ve already tried and gotten wrong.
30 points
Answer:
if there was a 15% discount, then you paid 75% of the original price. Since we don't know the orginal price, we will assign it the variable x. Change 75% to a decimal. The equation would be:
.75x = 208.25 To get the variable by itself, divide each side by .75
.75x/.75= 208.25/.75
x = 277.6
The original price of the suit was $277.6
I hope this helped you.

The local ice cream parlor bought 100 half gallons of gelato for $2.40 per half gallon and stored it in two freezers . One freezer broke, ruining 14 half gallons. If the remaining gelato is sold for $3.96 per half gallon, how much profit will the parlor make? Remember to include a dollar sign in your answer .
Answer:
The profit is $100.56
Step-by-step explanation:
The total cost for the ice cream was 100 * 2.40 = 240
14 1/2 gallons were ruined so there were 100 -14 = 86 half gallons left
They sold these at 3.96 each
86 * 3.96 =340.56
The profit is the money made minus the cost
340.56-240 = 100.56
The profit is $100.56
