One number is eight more than a second number. Five times the first is 8 less than 2 times the second. Find the numbers.
The value of the first number is?
The value of the second number is?
Step-by-step explanation:
let the 2 numbers be x and y.
x - 8 = y --(1)
5x = 2y - 8 --(2)
sub (1) into (2):
5x = 2(x - 8) - 8
5x = 2x - 24
3x = -24
x = -8
sub x = -8 into (1):
y = -8 - 8 = -16
first number is -8 and second number is -16.

At a little-known vacation spot, taxi fares are a bargain. A 18-mile taxi ride takes 21 minutes and costs $12.60. You want to find the cost of a 39- mile taxi ride. What unit price do you need?
Given :
A 18-mile taxi ride takes 21 minutes and costs $12.60.
To Find :
The cost of a 39- mile taxi ride. What unit price do you need.
Solution :
Unit price per mile :
[tex]p=\dfrac{12.60}{18}\\\\p = \$0.7\ /mile[/tex]
Cost of 39 mile taxi ride :
[tex]C = 39\times p\\\\C=39\times 0.7\\\\C=\$27.3[/tex]
Therefore, unit price is $27.3 and unit price is $0.7 / mile .
Hence, this is the required solution.

An emperor penguin travels a distance of 70 miles each year back to the place of its birth. If that same penguin moves at a speed of 2.4 miles per hour, the function d = 70 – 2.4t represents its distance d from its birthplace t hours after it has started its journey home. Find the zero of this function.
Answer:
29.17 hours
Step-by-step explanation:
to find the zero of the function, set d to equal zero, so
0 = 70 - 2.4t
-70 = -2.4t
-70/-2.4 = t
29.17 = t
Manual is a word processor operator and makes $11.50 an hour. How much is his gross earnings for one week if he worked a total of 52 hours? Determine regular pay, and overtime pay

63 miles / hour = 0.0175 miles / secondStep-by-step explanation:
63 miles per hour also equals 0.0108225108225108 feet per second.
Which does not really help you if you don't know how to convert feet per second to miles per second.
How to convert miles per hour to miles per second is fairly easy, with a calculator.
1 mile per hour equals 0.000277777778 miles / second,
and if you multiply 0.000277777778 by 63, you get = 0.01750000001
Which can be rounded to get 0.0175

Nick wants to purchase a pair of binoculars that is on sale for $155.75. The sales tax rate in his county is 6.5% Calculate the amount of sales tax Nick will pay on the purchase. Round to the nearest cent if necessary.
Answer:
$10.12Step-by-step explanation:
Step one:
given data
we are told that the cost of binoculars is $155.75
and also the sales tax is 6.5%
Step two:
We want to first solve for the sales tax which is 6.5% of $155.75
=6.5/100* 155.75
=0.065*155.75
=10.12
Nick will pay a tax of $10.12
Also Nick will pay a total amount of
= 155.75+10.12

Mike bought five items for lunch that cost a total of $4.55. Hot dogs cost $1.10 each and cookies cost $0.75 each. Which of these systems of equations below could be used to determine h , the number of hot dogs, and c , the number of cookies, Mike bought for lunch?
Answer:
1.1h+0.75c=4.55---------------1
h+c=5--------------2
Step-by-step explanation:
Step one:
given data
total lunch items= 5
let hot dogs be h
and cookies be c
cost of hot dogs = $1.10
cost of cookies = $0.75
total cost = $4.55
Step two:
The linear model for the total cost is given as
4.55=1.1h+0.75c---------------1
and the model for the number of items is
h+c=5--------------2
The systems of the equation for the situation is
1.1h+0.75c=4.55---------------1
h+c=5--------------2

solve 2v^2+4v=6 by factoring.
Answer:
v = 1 or -3
Step-by-step explanation:
2v^2 + 4v = 6
take 2 as common
2(v^2 + 2v = 3)
v^2 + 2v = 3
Now,
v^2 + 2v - 3 = 0
v^2 - v + 3v - 3 = 0
v(v - 1) + 3(v - 1) = 0
(v - 1) (v + 3) = 0
v = 1 or -3
Answer:
<=>v²+2v-3=0
<=>v²-v+3v-3=0
<=>v(v-1)+3(v-1)=0
<=>(v-1)(v+3)=0
<=>*v-1=0
v=1
*v+3=0
v=-3
