Solve. -7x + 29 = 6 (8+3x)
Answer:
Hi there
Your answer is
x = -.76 OR -19/25
Step-by-step explanation:
-7x +29 = 6(8+3x)
-7x +29 = 48 + 18x
-18x
-25x +29 = 48
-29
-25x = 19
/-25
x = -.76 OR -19/25
Answer:
x=-19/25 or x=-0.76

Write an equation and interpret the y-intercept.
You need $125 to buy an MP3 player. Your allowance is $5 per week and you earn $20 per lawn mowed
Write an equation that represents your weekly income in dollars for x lawns mowed. Interpret the y intercept . How many lawns do you need to mow to earn enough money in one week to buy the MP3 player?
Answer:
Answer in explanation
Step-by-step explanation:
The equation of a straight line can be represented in the form;
y = mx + c
where m is slope and c is y-intercept
In this particular case
y = 20x + 5
y is the weekly income, x is the number of lawns mowed
The y-intercept 5 is the amount earned in a week given they no lawn was mowed
In a case where y = 125
125 = 20x + 5
20x = 125-5
20x = 120
x = 120/20
x = 6
You need to mow 6 lawns to earn enough money in one week to buy the MP3 player
A circle is centered at the point O (0,0) and has a radius of the square root of 38?
Where’s does the K (6,1) lie?
Answer:
The point (6,1) lies inside the circle.
Step-by-step explanation:
Equation of a Circle
A circle centered at the point (h,k) and with radius r, can be expressed with the equation:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
The center of the given circle is (0,0) and the radius is [tex]r=\sqrt{38}[/tex], thus the equation of the circle is:
[tex](x-0)^2+(y-0)^2=(\sqrt{38})^2[/tex]
Simplifying:
[tex]x^2+y^2=38[/tex]
Each point (x,y) meeting the condition of the equation lies exactly on its circumference. For example, the point [tex](\sqrt{2},6)[/tex] belongs to the circumference, but the origin (0,0) is inside the circle, and the point (5,5) is outside the circle.
We can tell the difference by evaluating the equation at each point. For the first point [tex](\sqrt{2},6)[/tex], the equation is:
[tex](\sqrt{2})^2+6^2=2+36=38[/tex]
The equation is satisfied.
For the origin (0,0):
[tex]0^2+0^2=0[/tex]
For the point (5,5):
[tex]5^2+5^2=50[/tex]
We can conclude that if the left side is greater than 38, the point is outside the circle, if it's less than 38, the point is inside the circle.
Let's test the point (6,1):
[tex]6^2+1^2=37[/tex]
The point (6,1) lies inside the circle.
There are 270 students at Colfax Middle School, where the ratio of boys to girls is 5:4. There are 180 students at Winthrop Middle School, where the ratio of boys to girls is 4:5. The two schools hold a dance and all students from both schools attend. What fraction of the students at the dance are girls?
Given:
Total number of students at Colfax Middle School = 270
Ratio of boys to girls is 5:4.
Total number of students at Winthrop Middle School = 180
Ratio of boys to girls is 4:5.
The two schools hold a dance and all students from both schools attend.
To find:
The fraction of the students at the dance are girls
Solution:
There are 270 students at Colfax Middle School, where the ratio of boys to girls is 5:4.
[tex]5+4=9[/tex]
Number of boys [tex]=270\times \dfrac{5}{9}=150[/tex]
Number of girls [tex]=270\times \dfrac{4}{9}=120[/tex]
There are 180 students at Winthrop Middle School, where the ratio of boys to girls is 4:5.
[tex]4+5=9[/tex]
Number of boys [tex]=180\times \dfrac{4}{9}=80[/tex]
Number of girls [tex]=180\times \dfrac{5}{9}=100[/tex]
Now,
Total number of students in both schools [tex]= 270+180[/tex]
[tex]= 450[/tex]
Total number of girls in both schools [tex]= 120+100[/tex]
[tex]= 220[/tex]
The fraction of the students at the dance are girls is
[tex]\text{Required fraction}=\dfrac{\text{Total number of girls in both schools}}{\text{Total number of students in both schools}}[/tex]
[tex]\text{Required fraction}=\dfrac{220}{450}[/tex]
[tex]\text{Required fraction}=\dfrac{22}{45}[/tex]
Therefore, the required fraction is [tex]\dfrac{22}{45}[/tex].

Alexander is a stockbroker. He earns 11% commission each week. Last week, he sold $5,400 worth of stocks. How much did he make last week in commission? If he averages that same amount each week, how much did he make in commission in 2011?
Answer: 594 and 30888
Step-by-step explanation:
5400 x 0.11 = 594
594 dollars in commission of one week
52 weeks in a year
52 x 594 = 30888 dollars made in 2011
594 dollars in commission of one week.
$30888 he make in commission in 2011.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Stocks sold= $5400
Commission each week = 11%
So, Commission on Stocks sold
= 5400 x 0.11
= 594
Thus, 594 dollars in commission of one week.
As, 1 Year = 52 weeks
So, He can make in 2011 = 52 x 594 = $30888

Alisa uses her cell phone to search how many pounds of sand will is required to fill 1 cubic foot and finds out the answer is 100 pounds. Choose 1 of the brands and compute how much it will cost Alisa to purchase enough sand to fill the court. Sand b- 0.08$ per lb sand A- 0.08333 PLS HELP ME
This question is Incomplete
Complete Question
Alisa hopes to play beach volleyball in the Olympics someday. She has convinced her parents to allow her
to set up a beach volleyball court in their back yard. A standard beach volleyball court is approximately
26 feet by 52 feet. She figures that she will need the sand to be one foot deep. She goes to the hardware store to shop for sand and sees the following signs on pallets containing bags of sand.
Sand A = 60Ibs = $5
Sand B = 150lbs = $12
Alisa uses her cell phone to search how many pounds of sand is required to fill 1 cubic foot and finds the answer is 100 pounds. Choose one of the brands and compute how much it will cost Alisa to purchase enough sand to fill the court. Identify which brand was chosen as part of your answer.. Answer:
For Sand A should would need:
$11.266.67
Step-by-step explanation:
From the above question, we can assume that: her court is 1 cubic foot and can be filled with 100 pounds of sand
First we find the volume of the box
52ft × 26ft × 1 ft
= 1352 ft³
100Ib = 1 ft³
1352 ft³ × 100 Ib/ft³
= 135200Ibs
Sand A = 60Ibs = $5
Hence, $1 = 60Ibs/5
= 12Ibs
To purchase enough sand using Sand A to fill the court
= 135200Ibs/12lbs
= $11.266.67

-(1+7x)-6(-7-x)=36 what is x equal to
Answer:
x = 5
Step-by-step explanation:
Step 1: Write equation
-(1 + 7x) - 6(-7 - x) = 36
Step 2: Solve for x
Distribute: -1 - 7x + 42 + 6x = 36Combine like terms: -x + 41 = 36Subtract 41 on both sides: -x = -5Divide both sides: x = 5Step 3: Check
Plug in x to verify it's a solution.
-(1 + 7(5)) - 6(-7 - 5) = 36
-(1 + 35) - 6(-12) = 36
-(36) + 72 = 36
-36 + 72 = 36
36 = 36
