Answer:
X = -5, y = 8
Step-by-step explanation:
add the two equations together since the x‘s will cancel
-4y = -32
y = 8
then plug 8 in for y and solve
6x + 5(8) = 10
6x + 40 = 10
6x = -30
x = -5

Your mother gave you $13.32 with which to buy a present. This covered 3/5 of the cost. How much did the present cost?
A. Find the answer.
B. Write a formula for the problem.
Answer:
a. $22.2
b= 13.32/x=3/5
Step-by-step explanation:
13.32/x=3/5
13.32×5=66.6
66.6/3=22.2
x(present cost)=$22.2
Answer:
22.20$
3/5 * cost = 13.32
Step-by-step explanation:
3/5 * cost (total price) = 13.32 (we know that 3/5 of the price is 13.32)
to solve
5/3 to cancel out 3/5 and isolate the cost
5/3 * 13.32 = 22.20

2(5x - 3) - 4 = x + 4 solve for x and show work
Answer:
x= 14/9 = 1 5/9
Step-by-step explanation:
Use the distributive property to multiply 2 by 5x−3.
2(5x−3)−4=x+4
Subtract 4 from −6 to get −10.
10x−6−4=x+4
Subtract x from both sides
10x−10=x+4
Combine 10x and −x to get 9x.
10x−10−x=4
Add 10 to both sides.
9x−10=4
Divide both sides by 9.
x= 14/9

Denise gets paid $600 an hour plus $430 commission on her sales. If her paycheck this week was $700, how many hours did she work?
Find the slope of the line.Enter your answer in simplist form (-6,10) (-3,-2)
Answer:
-4
Step-by-step explanation:
I know this becasue I did it before but also becasue I checked my work with a slope calculator. You should use one if you don't want to hand do the work. If you do want to do the work it is y2-y1 over x2-x1 :)
A rocket ship travels at 2.0×104 miles per hour. If a satellite is 2.5×105 miles from Earth, how long will it take the rocket to make the trip from Earth to the satellite? (Hint: Divide the distance to the satellite by the speed.) Write your answer in scientific notation.
Answer: Time taken =1.25 x 10^1 hours 0r 4.5 x 10^4s
Step-by-step explanation:
Step 1
how long will it take the rocket to make the trip from Earth to the satellite = Time taken for the rocket to make the trip from Earth to the satellite
Speed = Distance / Time ,
Time = Distance / speed
Step 2-- solving
Time = Distance / speed
Time=2.5×10^5 miles/2.0×10^4 miles per hour
=12.5 hours = 1.25 x 10^1 hours
or 1.25 x 10^1 hours x 3600 = 45,000 seconds = 4.5 x 10^4s
In a company, 55 % of the workers are women . If 2205 people work for the company who aren't women , how many workers are there in all?
Answer:
4900
Step-by-step explanation:
If 55% of workers are women, then 45% are not; therefore, we need to answer the following:
2205 is 45% of what number?
2205=45%x
2205/.45=x
4900=x

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.
The population density of Iceland, in people per square kilometer of land area, increased from 2.5 in 1990 to
3.3 in 2014. During this time period, the land area of Iceland was 100,250 square kilometers. By how many
people did Iceland's population increase from 1990 to 2014?
A 330,825
B 132,330
C 125,312
D 80,200
Given:
The population density of Iceland, in people per square kilometer of land area, increased from 2.5 in 1990 to 3.3 in 2014.
Land area of Iceland = 100,250 square kilometers.
To find:
The Iceland's population increase from 1990 to 2014.
Solution:
Land area of Iceland is constant, i.e., 100,250 square kilometers.
The population density of Iceland, in people per square kilometer of land area in 1990 is 2.5. So, the population in 1990 is
[tex]2.5\times 100,250=250,625[/tex]
population density of Iceland, in people per square kilometer of land area in 2014 is 3.3. So, the population in 2014 is
[tex]3.3\times 100,250=330,825[/tex]
The Iceland's population increase from 1990 to 2014 is
[tex]330,825-250,625=80,200[/tex]
Therefore, the correct option is D.

A producer received rupees 10000 when the price of a commodity was rupees 100 per unit. The receipts increased to rupees 15000 when price increased by rupees 20.Calculate the elasticity of supply?
Answer:
Price Elasticity of Supply = 1.25
Step-by-step explanation:
Price Quantity Total Revenue ( P x Q)
100 10000/100 = 100 10000
120 15000/120 = 125 15000
Price Elasticity of supply is change in quantity supplied, due to change in price. Formula : (dQ / dP) x (P / Q)
(125 - 100) / (120 - 100) x (100/100)
= 25/20 = 1.25

Answer:
3x -4y = 12
Step-by-step explanation:
There are a number of different forms of the equation of a line. A few are ...
y = mx + b . . . . slope-intercept form
y -k = m(x -h) . . . . point-slope form
x/a +y/b = 1 . . . . intercept form
ax +by +c = 0 . . . . general form
ax +by = c . . . . standard form
In "standard form", the coefficients a, b, c are mutually prime integers (have no common factors) and the leading coefficient (usually, 'a') is positive.
__
Given this graph, there are several ways to get to a standard form equation. Perhaps the quickest is to start with intercept form. We can see from the graph that the x-intercept is 4 and the y-intercept is -3. So, we can write the equation of the line in intercept form as ...
x/4 +y/(-3) = 1
Multiplying this by 12 clears the fractions and gives us standard form:
3x -4y = 12
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
