Answer:
101
Step-by-step explanation:
4x+11 + 6x -1 = 180 (because they are supplementary)
10x =170
x = 17
angle L = 6(17) - 1 = 101
Angle L and Angle N are congruent. so N = 101

What is expression in mathematics?An expression in mathematics is a combination of terms both constants and variables.
Given are two labelled bars shown next to each other and each bar.
3 of the 8 bars are colored. Using fraction, we can represent it as -
{f} = 3/8
There are two such bars, so we can write -
y = 2{f}
y = 2 x 3/8
Therefore, the expression that is represented by the model below is -
y = 2 x 3/8.

The algebraic expression that represents the phrase "fourteen increased by a number" is 14 + y. which is the correct answer that would be an option (A).
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
The given statement is "fourteen increased by a number"
According to the given question, translate the phrase into an algebraic expression:
⇒ 14 + y
This is because the phrase "increased by" means to add a certain number to 14.
The variable y represents the number that is being added to 14.
Thus, the algebraic expression that represents the phrase "fourteen increased by a number" is 14 + y.
Hence, the correct answer would be option (A).

A store has apples on sale for $21.00 for 6 pounds. If an apple is approximately 5 ounces, how many apples can you buy for $126.00? Complete the explanation.
Answer:
115 apples
Step-by-step explanation:
6 pounds of apple = $21.00
Cost per pound :
$21.00 / 6 = $3.5 per Pound
1 pound = 16 ounces
16 ounces cost $3.5
1 ounce = $3.5 / 16 = $0.21875
5 ounces will cost :
5 * 0.21875 = $1.09375
Number of 5 ounce apple that can be purchased with $126
$126 / $1.09375
= 115.2
Approximately 115 apples

A=1.89×10 7 (7 as the exponent)
Explanation:
There are 99 males and 121 females participating in a marathon. What percent of the participants are female?
To do this, we first want to see how many participants there are in total by adding both males and females.
[tex]99+121=220[/tex]
Now we know that there were 220 total participants, but only 121 were females.
This allows us to set up the fraction 121/220= the percent female.
[tex]\frac{121}{220} =0.55[/tex]
or 55%

Terms/CoefficientsCoordinates (x, y)Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
3x + 4y = -2
2x + 3y = -1
Step 2: Rewrite Systems
Find LCM of both equations.
[1st Equation] Multiply everything by 2: 6x + 8y = -4[2nd Equation] Multiply everything by -3: -6x - 9y = 3Step 3: Redefine Systems
6x + 8y = -4
-6x - 9y = 3
Step 4: Solve for y
Elimination
Combine 2 equations: -y = -1[Division Property of Equality] Divide -1 on both sides: y = 1Step 5: Solve for x
Define original equation: 3x + 4y = -2Substitute in y: 3x + 4(1) = -2Multiply: 3x + 4 = -2[Subtraction Property of Equality] Subtract 4 on both sides: 3x = -6[Division Property of Equality] Divide 3 on both sides: x = -2write an expression in simplified form to represent the area of the trapezoid

"write a linear equation for line m,n,l,p"
Answer:
Step-by-step explanation:
m: y = -2x + 4
n: y = x - 1
l: y = 4
p: x = -4
m: y=-2x+4
slope: 2
2/1=2
Its negative because the line is going down from left to right
y-intercept:
it crosses the y axis at (0,4)
n: y=x-1
slope: 1
1/1=1
Its positive because the line is going up from left to right
y-intercept:
it crosses the y axis at (0,-1)
l: y=4
slope: 0
A vertical line's slope is always 0
y-intercept:
it crosses the y axis at (0,4)
p: x=-4
To find the equation for a horizontal line, you need to find what x always is no matter what.
