Step-by-step explanation:
23+13 = ?
The two fractions already have like denominators, so just add the numerators:
-23+13=-2 + 13=-13
The result is:
-23+13=–13
Answer:
-2/3 + 1/3 = -1/3
Step-by-step explanation:
using addition to solve a fraction with the same base
step 1: take the denominator of both fractions and clear them from the equation
ex: -2/3 + 1/3 = ? (-2 + 1 = ?)
step 2: solve the new equation -2 + 1 to get your answer of
ex: -2 + 1 = ? (-2 + 1 = -1)
step 3: since both denominators of the fractions have the same number then our answer will also have a denominator of 3 giving us the answer to the problem -2/3 + 1/3 = ? is -1/3

The math problem is below
Answer:
Brooklyn earns four more dollars than Anna does each hour.
Step-by-step explanation:
So basically in order to get the amount ech of them recieve you would have to divide. So for Anna's since her least given number is 10 hours you would divide how much she earns (256) by how many hours she has been working (10) and you get 25.6
Now for Brooke she is given only one piece of evidence so you would use that she has been working for 26 hours and earns 769.6. So divide her earning by the hour and get 29.6
Subtract each of the answers (29.6-25.6) and you would get 4

6. Monthly Mortgage payments can be found using the formula Below:
M-PG2)(1+1)"
(1+12"-1
M = monthly payment
P = amount borrowed
r=annual interest rate
n = number of monthly payments
The Ranallo family just bought a house. They qualified for an annual interest rate of 5.2% and their monthly payment
was $800 for a 30 year mortgage. Algebraically determine the amount of their loan to buy the house.
Answer: your equation is poorly written/wrong hence I used the equation below
answer : $289156.63
Step-by-step explanation:
applying the formula to calculate monthly repayment of Mortgage
M = P [ r(1+r)^n / ( ( 1+r )^n ) -1 ) ] ----- ( 1 )
M = Total monthly payment = 800 * 12 * 30 = $ 288,000
P = ?
r = 5.2% / 12 = 0.4%
n = 30 * 12 = 360 months
Back to equation 1
P = M / [ r(1+r)^n / ( ( 1+r )^n ) -1 ) ]
= 288000 / [ 0.004 ( 1.004)^360 / (( 1.004)^360 ) - 1 ) ]
= 288,000 / -0.996 = - $289156.63 ( It has a negative value because It is a loan borrowed )
An equilateral triangle has an altitude length of 33 feet. Determine the length of a side of the triangle.
Answer:
38.11 feet
Step-by-step explanation:
all three corners of an equilateral triangle are 60°
sin 60° = 33/x
0.8660 =33/x
x = 38.11 feet
Relation between the side and the altitude of the equilateral triangle can be given as,
[tex]a=\dfrac{2}{\sqrt{3} } h[/tex]
The length of the side of the equilateral triangle is 38.105 feet.
What is equilateral triangle?When all the three sides and all the three angle of a triangle are equal, then the triangle is known as Equilateral triangle.
Relation between the side and the altitude of the equilateral triangle can be given as,
[tex]a=\dfrac{2}{\sqrt{3} } h[/tex]
Here, [tex]a[/tex] is the side of the equilateral triangle and h is the altitude of the equilateral triangle
Given information-
Altitude of the equilateral triangle is 33 feet.
Put the value of altitude in above formula to find the length of the side of the equilateral triangle. Thus,
[tex]a=\dfrac{2}{\sqrt{3} } \times33\\a=38.105[/tex]
Thus the length of the side of the equilateral triangle is 38.105 feet.

The number 18 is decreased to 16. What is the percentage by which the number was
decreased, to the nearest tenth of a percent?
Answer:
11.1 %
Step-by-step explanation:
2/18 = 11.1%
The percentage of the number decreased is 11.1%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Initial number = 18
Final number = 16
The change in the value of the number.
= 18 - 16
= 2
The percentage decreased.
= (Change in the number / Initial number) x 100
= 2/18 x 100
= 200/18
= 11.11%
= 11.1 %
Thus,
The percentage decreased is 11.1%.

Two triangles are similar. The lengths of the sides of the smaller triangle are 3 inches, 5 inches, and 6 inches, and the length of the longest side of the larger triangle is 18 inches. What is the perimeter of the larger triangle?
A.
14 inches
B.
18 inches
C.
24 inches
D.
42 inches
Answer:
42 (d)
Step-by-step explanation:
the longest side of the smaller one is 6, each side of the larger one is just 3x the length of the smaller side. I hope that makes sense, it's just a ratio. Hope this helped! Good luck!
Answer:
The perimeter of the larger triangle is 42 inches.
Step-by-step explanation:
Since the question mentions that the two triangles are similar, we must establish proportions using what we already know.
Smaller triangle: 3 + 5 + 6 = 14
Larger triangle: x + y + 18 = perimeter
Determine the GCF (greatest common factor):
The GCF is 3.
Now, subsitute the values for x and y by solving via the GCF.
Larger triange: 9 + 15 + 18 = perimeter
9 + 15 + 18 = 42
