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
Answers
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

Find the difference in the given lengths of the polygons . (7x + 2) units (6x - 5) units .
Answers
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.

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?
Answers
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
The percent of decrease from 69 songs to 37 songs?
Answers
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%

Answer:

Step-by-step explanation:
(5x + 10) + 55 = 90
5x + 10 + 55 = 90
5x + 65 = 90
5x + 65 - 65 = 90 - 65 (the 65 crosses off)
5x = 25
5x/5 = 25/5

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.
Answers
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°
