1/2r−3=3(4−3/2r)
Answer:
r = 3
Step-by-step explanation:
[tex]\dfrac{r}{2} - 3 = 3(4 - \dfrac{3r}{2} )[/tex]
The first step to solve for "r" is to simplify the distributive property on the RHS. To simplify the distributive property, we need to multiply the term outside the parenthesis with the terms inside the parenthesis.
[tex]\rightarrow \dfrac{r}{2} - 3 = 12 - \dfrac{9r}{2}[/tex]
Now, add 9r/2 and 3 both sides to isolate the constants and variables.
[tex]\rightarrow \dfrac{r}{2} + \dfrac{9r}{2} = 12 + 3[/tex]
Simplify both sides.
[tex]\rightarrow \dfrac{10r}{2}= 12 + 3[/tex]
[tex]\rightarrow 5r = 15[/tex]
Divide 5 both sides.
[tex]\rightarrow \boxed{r = \frac{15}{5} = 3}[/tex]
3) Alex drove for 3 hours at an
average speed of 60 miles per
hour and for 2 hours at 45
miles per hour. What is his
average speed for the whole
journey?
average speed= total distance/total time taken
60+45= 105miles
1 mile= 1.609
105×1.609= 168.945km
168.945/4
Hence answer = 33.79 km/hr
Answer:
To find Alex's average speed for the whole journey, we can use the formula:
Average Speed = Total Distance / Total Time
Let's calculate the total distance traveled first:
Distance1 = 60 miles/hour * 3 hours = 180 miles
Distance2 = 45 miles/hour * 2 hours = 90 miles
Total Distance = Distance1 + Distance2 = 180 miles + 90 miles = 270 miles
Next, let's calculate the total time taken for the whole journey:
Total Time = 3 hours + 2 hours = 5 hours
Now, we can find the average speed:
Average Speed = 270 miles / 5 hours = 54 miles per hour
So, Alex's average speed for the whole journey is 54 miles per hour.

On the average, how many times must a die be thrown until one gets a 6?
Answer:
6
Step-by-step explanation:
There are 6 faces on a die so on average, one has to roll a fair die 6 times in order to get number 6 to show.
On average it's 6 as 6 sides a die has
But
There is equal probability for each number while rolling a die .i.e
There is 1/6 chances getting any number

Which system of equations represents the graph?
for the line that goes up - it cuts the y-axis at - 5 (p = -5)
when we take 2 points we go from one to the other by going to the right of 1 unit and going up of 3 units (slope m : 3/1)
=> y = 3x - 5
and
for the line which goes down - it cuts the y-axis in +2 (p=2)
when we take 2 points we go from one to the other by going to the right of 2 units and going down of 1 unit (slope m : -1/2)
=> y = -1/2x + 2
=> y + 1/2x = 2
2x + 4y = 8

Rashmi bought 2/3 meter of cloth and Madhu bought 2/5 meter of cloth. Who bought more cloth and how much?
Rashmi =4/15
Madhu=4/15
Rashmi=3/10
Madhu=3/10
Answer:
Reshmi bought more cloth by 4/15...
Step-by-step explanation:
1st equalize the denominator of 2/3 and 2/5
lcm of the denominators 3 and 5 is 15
2/3*5/5=10/15
2/5*3/3=6/15
Rashmi bought 10/15 m cloth
madhu bought 6/15 m cloth .
therefore, Rashmi bought more cloth
by how much more?
10/15-6/15 = 10-6/15=4/15
therefore, reshmi bought more cloth by 4/15

HELP PLEASE! 40 POINTS AND WILL MARK BRAINLIEST.
Suppose you want to find the 40th term of a sequence. Would you rather use a recursive rule or an explicit rule? Explain your reasoning.
Answer:
Explicit rule, because you can find the 40th term directly using the explicit rule. You would need to find the first 39 terms before finding the 40th terms using recursive rule.

A store sells paint sets each paint set costs the same amount during a sale the store reduces the price of each paint set by $1.35 Jenny sends $6.88 on 2 paint sets at the sale price. What was the price of 1 paint set before the sale?
Answer:
$4.79
Step-by-step explanation:
divide $6.88/2
add $1.35 that's it
Money reduction on a paint set during a sale = $1.35
Cost of two paint sets Jenny bought in a sale = $6.88
Given :-
Cost of every paint set is equivalent .
Then :-
Cost of each paint set during the sale :-
[tex] = \frac{6.88}{2} [/tex]
[tex] = $3.44[/tex]
The cost of each painting set during the sale was $3.44 .
Cost of each paint set before the sale :-
[tex] = 3.44 + 1.35[/tex]
[tex] =$4.79[/tex]
Therefore , the cost of each paint set before the sale was = $4.79 .

For what values of a are the following expressions true?
| a-5 | = 5-a
what values of a are the following expressions true?
Expression :-|a-5| =5-a
Answer:-Try putting values of ( a )
Greater than 5 Less than 5 Equal to 5First attempt :- Greater than 5picking random number :-
Putting a = 6 :-
[tex] |a-5| =5-a \\ |6-5| =5-6 \\ | 1| = -1 \\ 1 \cancel = ( - 1) [/tex]
so a is not equal to 6
Putting a = 8
[tex]|a-5| =5-a \\ |8 - 5| =5-8 \\ |3| = - 3 \\ 3 \cancel = - 3[/tex]
a is also not equal to 8
so above values we can find a common result that a not equal to value bigger than 5
Second attempt :- Less than 5picking random number
Putting a equal to 1
[tex]|a-5| =5-a \\|1-5| =5-1 \\ | - 4| =4 \\ 4 = 4[/tex]
a can be equal to 1
Putting a equal to -3
[tex]|a-5| =5-a \\| - 3-5| =5-( - 3) \\ | - 8| = 8\\ 8 = 8[/tex]
a can be equal to -3
So we can have a common result that a can be equal to values less than 5
Third attempt :- a equal to 5putting a equal to 5
[tex]|a-5| =5-a \\ |5 - 5| =5-5 \\ |0| =0 \\ 0 = 0[/tex]
So we can say a can be equal to 5
Result :- (a) can be equal to or less than 5guys please help me i need this done NOW
