Answer:
12/7
Step-by-step explanation:
5/3x+10/7=30/7
5/3x=30/7-10/7
5/3x=20/7
x=(20/7)/(5/3)
x=(20/7)(3/5)
x=60/35
simplify
x=12/7
This equation can be used to find p, the number of dollars Della earned after selling her handmade doll clothes at a craft fair. p = 210 − (20 × 4) What was the amount of Della's profit?
A) $80
B) $105
C) $130
D) $150
Answer:
C) $130
Step-by-step explanation:
simplify the equation:
p = 210 - (20 * 4)
p = 210 - (80)
p = 130

answer : 36080
Step-by-step explanation:
Finished good inventory = 24% of next month estimated sales
Determine the budget level of production for September
For September
Initial unit on table = 38,000
Beginning inventory = 24% of 38000 = 9120
ending inventory = 24% of 30,000 = 7200
∴ Budget level of production = 38000 - 9120 + 7200 = 36080 units

Answer: 72.32
Step-by-step explanation:
The line is 180 so
7x + 8x + 44.4 = 180
15x + 44.4 = 180
-44.4 = -44.4
15x = 135.6
divide both by 15
x = 9.04
So 8 * 9.04 = 72.32
Answer:
The answer is 72.32°
Step-by-step explanation:
So, since that is a straight line, we know that all of the angles add up to get 180° total. Using this knowledge, we can determine that 44.4 + 8x + 7x = 180°.
First, we need to find what x is to find the missing values. To do that, we have to set all the values, 44.4, 8x, and 7x equal to 180, because we know they add up to 180°.
44.4 + 8x + 7x = 180
Combine the like terms.
44.4 + 15x = 180
Bring the 44.4 over to the other side in order to get x alone by subtracting it from 180.
15x = 135.6
Divide both sides by 15 to get x completely alone.
x = 9.07
Now we have what x is, 9.07.
All you need to do now is substitute 9.07 into the place of x.
8(9.07) = 72.32
So now you know that the highlighted angle is 72.32°.

Zymirah earns 5% commission on all sales at a jewelry store plus $10 an hour. Yesterday she sold $3,200 in merchandise and earned a total of $240. How many hours does she work?
Answer:
8 hours
Step-by-step explanation:
Given data
Commission= 5%
Sales= $3,200
Total earnings= $240
Let us find the amount in commission earned
=5/100*3,200
=0.05*3,200
=$160
Hence 240-160=$80
$80 is the amount earned yesterday
we are told that per hour is $10
Hence $80 will be earned for
=80/10
=8 hours

Answer:
It is not correct, x = -5
Step-by-step explanation:
Answer:
no

because 5+15=10
-15=15
x= -5
which means its NOT a solution because it equals -5

Using the equation y=kx what would be the proportionate equation if she worked 25 hours and made 150.00
Answer:
y = 6x
Step-by-step explanation:
Equation representing the relation between duration of work and earning is,
y = kx
Here, y = earnings
x = Working hours
k = Proportionality constant
By substituting the values in the given equation,
x = 25 hours
y = $150
150 = k(25)
k = 6
Therefore, equation modeling the situation will be,
y = 6x
is this a supplementary angle or a complementary angle or neither?? number 1
Answer:
its neither

An aeroplane is 528 ft directly above an automobile and starts east at the rate of 20 miles an hour at the same instant the automobile starts east at the rate of 40 miles an hour. How fast are they separating
Answer: 20 mph
Step-by-step explanation:
Given
The airplane is at a height of 528 ft with a rate of 20 mph
The automobile is also directing east at the rate of 40 mph
at this instant, they are separating by the relative velocity between them

What are the cordinates of the point on the directed line segment from -3 -9 to 4 5 that partitions the segment into a ratio of 5 to 2
Answer:
[tex](x,y) = (2,1)[/tex]
Step-by-step explanation:
Given
Coordinate: (-3,-9) and (4,5)
Ratio= 5 : 2
Required
Determine the point at the segment
The coordinate of the point is calculated using:
[tex](x,y) = [\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n}][/tex]
Where:
[tex]m : n=5:2[/tex]
[tex](x_1,y_1) = (-3,-9)[/tex]
[tex](x_2,y_2) = (4,5)[/tex]
So, we have:
[tex](x,y) = [\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n}][/tex]
[tex](x,y) = [\frac{5 * 4 + 2 * -3}{5+2},\frac{5*5+2*-9}{5+2}][/tex]
[tex](x,y) = [\frac{14}{7},\frac{7}{7}][/tex]
[tex](x,y) = (2,1)[/tex]
The coordinate of the point is: (2,1)
Students sell 80% of the books at a book slae. They sell 48 books in all. How many books are at the book sale? Show your work.
Answer:
60 books were at the book sale
Step-by-step explanation:
Let
x = total books at the book sale
Percentage of books sold = 80% of x
= 80/100 * x
= 0.8x
Number of books sold = 48
Therefore,
0.8x = 48
Divide both sides by 0.8
0.8x / 0.8 = 48 / 0.8
x = 60 books
x = total books at the book sale = 60 books
Number of books unsold = Total books at the book sale - number of books sold
= 60 - 48
= 12
Number of books unsold = 12 books

Write the Equation of the line in fully simplified slope- intercept form
Answer:
y=-6/5x-2
Step-by-step explanation:
We are given points (5,-8) and (-5,4)
Slope = m = (y₂-y₁)/(x₂-x₁) = (-8-4/(5-(-5)) = -12/10 = -6/5
Y-intercept = b = (0,-2)
Final equation: y=-6/5x-2
Answer:
y=-6/5x-2
Step-by-step explanation:
y=mx+b
Its sloping downwards, so a negative slope.
two points: (-5,4) and (5,-8)
---------------------------------------------
so first find the slope.
y2-y1 / x2-x1 <= formula
so: -8-(4) / 5-(-5)
which becomes => -12/ 10
which is 6/5 the slope is 6/5
------------------------------------------
plug this into y=mx+b, where m is the slope
so: y=6/5x+b
------------------------------------------
obviously b is the y intercept, where the line meets y
the y intercept is -2
sooooooo final answer is
----------------------------------
y=6.5x+(-2)
-----------------------------------
Negative slope, so becomes y=6/5x-2
Sophia needs to know the area and perimeter of his property. The length of his property is 1/5 mile and the width is 3/8 mile. What is the perimeter of Sophia's property?
Answer:
See the answers below
Step-by-step explanation:
Given data
Length = 1/5mile
Width= 3/8 mile
The expression for the perimeter
P=2L+2W
Substitute
P=2*1/5+ 2* 3/8
P= 2/5+6/8
P= 16+30/40
P=46/40
P= 23/40 miles
Area= Length *Width
Area= 1/5* 3/8
Area= 3/40 square miles
