Answer:
15w+5
Step-by-step explanation:
Any like terms can be combined to simplify.
2w+13w=15w
4+1=5
So, 2w+4+13w+1= 15w+5
Answer:
W = -1/3
Step-by-step explanation:
15W + 5= 0
15W = -5
W = -5/15
W = -1/3
Look at this system of equations.
-3x+3y=12
y=x+4
The solution set of this system is best explained by which of these statements?
A
The graphs of the equations are parallel lines because they have the same slope but different y-intercepts. The system has no solution.
B
The graphs of the equations are the same line because the equations have the same slope and the same y-intercept. The system has infinitely many solutions.
C
The graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. The system has exactly one solution.
D
The graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. The system has exactly one solution.
Answer:
D. The graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. The system has exactly one solution.

If Holly gets 14 % off a shirt , what percent of the original price will still pay
Answer:
Holly will still pay 86% of the original price.
Step-by-step explanation:
Given
Holly gets 14% off a shirt, soDiscount = 14%To determine
What percent of the original price will still pay.
All we need is to subtract the percentage of discount from 100.
i.e.
100 - Discount = 100 - 14 = 86%
The amount left over would be what remains of the original price after Holly gets 14 % off a shirt.
Thus, Holly will still pay 86% of the original price.

5 divided 9/10 in fractions forms
Answer: 5 5/9
Step-by-step explanation:
cause that’s the answer
5 divided by 9/10, in fraction form, is 50/9.
To divide 5 by 9/10, we can convert the whole number 5 into a fraction with a denominator of 1.
5 can be expressed as 5/1.
We can rewrite the division problem as a multiplication problem by taking the reciprocal (flipping the numerator and denominator) of the divisor:
5/1 ÷ 9/10
= 5/1 × 10/9
Multiply the numerators together and the denominators together:
(5×10) / (1 × 9) = 50/9
Therefore, 5 divided by 9/10, in fraction form, is 50/9.

The length of the side k in the given triangle is 1,373.9 cm.
What is cosine law?The law of Cosines, also known as Cosine Rule or Cosine Formula basically relates the length of the triangle to the cosines of one of its angles.
Given that, in ΔKLM, l = 820 cm, m = 560 cm and ∠K=169°, we need to find the length of side k,
Using the cosine law,
k² = l²+m² - lmCos169°
= 820²+560²-(820)(560)cos169°
= 1,373.9
Hence, the length of the side k in the given triangle is 1,373.9 cm.

The graph of g(x) is the result of translating the graph of f(x) = [1/2]× three units to the left. What is the equation of g(x)?
A. g(x)=[1/2]×-3
B. g(x)=[1/2]×+3
C. g(x)=[1/2]×-3
D. g(x)=[1/2]× +3
To shift a graph to the left you add to the x value
The answer would be B. g(x)=[1/2]×+3
The equation of g(x) = [1/2]x + 3 which is correct option (B)
What is translation of graph?A translation of a graph is a shifting of the graph either horizontally or vertically parallel to the axis.
If g(x) was translated three units to the left to create f(x)= [1/2]x, then
g(x) - 3 = f(x)
g(x) = f(x) + 3 = [1/2]x + 3
So g(x) = [1/2]x + 3

At school 40% of the teachers teach English if 20 teachers teach English how many teachers work at school
Answer:
Step-by-step explanation:
Change the 40% to a decimal, which is 40/100 or also equivalent to 2/5
Then divide the number of teachers by the percentage/decimal of teachers
20/(2/5) = 100/2 = 50 total teachers
The total number of teachers in the school is 50 teachers
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Let the total number of teachers in the school be = A
The percentage of teachers in the school who teach English = 40 %
The total number of English teachers = 20 teachers
So the percentage equation is ,
To calculate the total number of teachers
40 percentage of total teachers = 20 English teachers
So ,
( 40 / 100 ) x A = 20
Multiply by 100 on both sides , we get
40A = 2000
Divide by 40 on both sides , we get
A = 50
Therefore , the value of A is 50
Hence , the total number of teachers in the school is 50 teachers

What is y? Helppp thank you !
Answer:
y = 42
Step-by-step explanation:
Since QT is a midsegment then it is half of RS , that is
QT = [tex]\frac{1}{2}[/tex] RS, substitute values
y = [tex]\frac{1}{2}[/tex] (y + 42) ← multiply both sides by 2 to clear the fraction
2y = y + 42 ( subtract y from both sides )
y = 42
