Answer: 400 cm
Step-by-step explanation:
create a ratio
1 is to 40 as 10 is to x
1/40 = 10/x
multiply both sides by 40 and divide by x

Find the difference in the given lengths of the polygons . (7x + 2) units (6x - 5) units .
Answer:
Difference in the lengths of the polygons is (x + 7) units.
Step-by-step explanation:
Lengths of the given polygon = (7x + 2) units and (6x - 5) units
Therefore, difference in the given lengths = (7x + 2) - (6x - 5)
= (7x - 6x) + (2 + 5)
= x + 7
Therefore, difference in the lengths of the polygons is (x + 7) units.
Solve the system of equations
-12x+9y=7
3x+4y=2
Show all workings please
Answer:
x = -2/15 & y = 3/5
Step-by-step explanation:
- 12x + 9y = 7 ...(1) ; 3x + 4y = 2 ...(2)
Multiply both sides of (2) by 4:
12x + 16y = 8
Add the new equation & (1):
12x + 16y = 8
-12x + 9y = 7
0 + 25y = 15 => y = 15/25 = 3/5
Thus, substitute the value of y in (2):
3x + 4y = 2 => 3x = 2 - 4(3/5) = (10-12)/5
=> 3x = -2/5
=> x = - 2/15
Answer:
[tex]x=-\frac{2}{15}=-0.133333333\\y = \frac{3}{5}= 0.6[/tex]
Step-by-step explanation:
−12x+9y=7
3x+4y=2
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
−12x+9y=7,3x+4y=2
To make −12x and 3x equal, multiply all terms on each side of the first equation by 3 and all terms on each side of the second by −12.
3(−12)x+3×9y=3×7,−12×3x−12×4y=−12×2
Simplify.
−36x+27y=21,−36x−48y=−24
Subtract −36x−48y=−24 from −36x+27y=21 by subtracting like terms on each side of the equal sign.
−36x+36x+27y+48y=21+24
Add −36x to 36x. Terms −36x and 36x cancel out, leaving an equation with only one variable that can be solved.
27y+48y=21+24
Add 27y to 48y.
75y=21+24
Add 21 to 24.
75y=45
Divide both sides by 75.
y=3/5
Substitute 3/5 for y in 3x+4y=2. Because the resulting equation contains only one variable, you can solve for x directly.
3x+4×(3/5)=2
Multiply 4 times 3/5
3x+12/5=2
Subtract 12/5 from both sides of the equation.
3x=-2/5
Divide both sides by 3.
x=-2/15
The system is now solved.
x=−2/15 ,y=3/5
i need help finding the y-intercept
Answer: (0, -7)
Step-by-step explanation:
y = mx + b
Where m is slope and b is y-intercept
y = 2x + b
One point that passes through the line is (5,3), which means that x = 5 and y = 3
3 = 2(5) + b
3 = 10 + b
b = -7
(0, -7) is the y-intercept
Using this info you can find the equation of the line

The percent of decrease from 69 songs to 37 songs?
Answer:
46.3768%
Step-by-step explanation:
Or 46.38% if you round it to the nearest tenths
The percentage decrease of songs from 69 to 37 songs is 46.4%.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, The number of songs decreased from 69 songs to 37 songs.
Therefore, The net amount of songs that decreased is,
= (69 - 37).
= 32 songs.
Now to obtain percentage change we'll divide the net amount change by the original amount and multiply it by 100% which is,
= (32/69)×100.
= 46.4%

A rectangle is 60 cm long and 20 cm wide. Find, to the nearest tenth of a degree, the acute angle formed at the intersection of the diagonals.
Answer:
36.9°
Step-by-step explanation:
As shown in the diagram attached,
θ is the acute angle formed at the intersection of the diagonals of the rectangle.
From the diagram,
tan(θ/2) = 10/30
tan(θ/2) = 1/3
θ/2 = tan⁻¹(1/3)
θ/2 = 18.43
Therefore,
θ = 18.43×2
θ = 36.87
θ = 36.9°
Hence the acute angle formed is 36.9°
Mary bought 2 large popcorn buckets and 4 small drinks for $20. Linda bought 2 large popcorn buckets and 2 small drinks for $14. What was the cost for the large popcorn and the small drink?
Answer:
the cost for the large popcorn and the small drink is $4 and $3 respectively
Step-by-step explanation:
The computation of the cost for the large popcorn and the small drink is shown below:
Let us assume the cost of the large popcorn be x
ANd, the small drink cost be y
Now as per the question
2x + 4y = $20
2x + 2y = $14
Now subtract equation 2 from equation 1
2y = $6
y = $3
Now for x it is
2x + 12 = $20
2x = $8
x = $4
Hence, the cost for the large popcorn and the small drink is $4 and $3 respectively

A baby elephant weighs 1,400 pounds, which is 7,437 pounds less than her mother. Which equation expresses the weight of the mother? * n – 1,400 = 7,437 n + 1,400 = 7,437 n x 7,437 = 1,400 n + 7,437 = 1,400
Answer:
n – 1,400 = 7,437
Step-by-step explanation:
A baby elephant weighs 1,400 pounds, which is 7,437 pounds less than her mother.
Let us represent :
Weight of the mother elephant = x
Weight of the baby elephant = y
A baby elephant weighs 1,400 pounds, which is 7,437 pounds less than her mother.
y = x - 7437 pounds
Hence,
1400 pounds = x - 7437 pounds
The weight of the mother elephant =
x = 1400 pounds + 7437 pounds
Therefore, the equation that expresses the weight of the mother where, the weight of the mother = n is:
n – 1,400 = 7,437
