One half of a is 14 more than 2 times the number.find the number?
Answer:
Let n represent the number
One half of a number= ½ n
Now, the equation will be=
½ n =14+2n
On multiplying both sides by 2, we obtain
n=2(14+2n)
n=28+4n
On subtracting 4n from both the sides,we obtain
n-4n=28
-3n=28
On dividing both sides by -3, we obtain
n= -28/3

A taxi charges a flat fee of $5.00 plus $3.25 per mile.
How much will it cost to travel 8.7 miles? Round your answer to the nearest cent.
Answer:
$33.28
Step-by-step explanation:
8.7 times 3.25 is 28.275

Answer:
$33.28
Step-by-step explanation:
So, we would multiply $3.25 by 8.7 miles.
$3.25 · 8.7 = $28.28
Then we would add on the additional $5.00
$28.28 + $5.00 = $33.28

6.) Consider the functions f(x) = -2x + 1 and g(x) = 4x - 5
find f(3)
Answer:
[tex]f(3)=-5[/tex]
Step-by-step explanation:
We have the functions [tex]f(x)=-2x+1[/tex] and [tex]g(x)=4x-5[/tex]
We want to find [tex]f(3)[/tex]. So, we can use our first function.
Substitute 3 for x. This yields:
[tex]f(3)=-2(3)+1[/tex]
Multiply:
[tex]f(3)=-6+1[/tex]
Add:
[tex]f(3)=-5[/tex]
So:
[tex]f(3)=-5[/tex]

s congruent to . If angle S is (5x-11) degrees and angle U is (4x+9) degrees, find the value of x.
Given:
Consider angle S is congruent to angle U.
The angle S is (5x-11) degrees and angle U is (4x+9) degrees,
To find:
The value of x.
Solution:
Since it is given that angle S is congruent to angle U, therefore the measure of theses two angles are equal because measure of congruent angles are equal.
[tex]m\angle S=m\angle U[/tex]
Put the given values.
[tex]5x-11=4x+9[/tex]
Subtract 4x from both sides.
[tex]5x-4x-11=9[/tex]
Add 11 on both sides.
[tex]x=9+11[/tex]
[tex]x=20[/tex]
Therefore, the value of x is 20.
Rebecca’s boss pays her time and a half for overtime work. If her regular wage is $13.50 per hour, what is her overtime rate?
Answer:
Rebecca's overtime rate is $20.25 per hour
Step-by-step explanation:
Rebecca is paid $13.50 per hour as her regular wage.
Her boss pays her that amount and a half for overtime work.
Half of her regular pay rate is 13.50/2= $6.75
Thus, her overtime rate is:
$13.50 + $6.75 = $20.25
Rebecca's overtime rate is $20.25 per hour
