Answer:
x = 14
BE = 6
Step-by-step explanation:
to find 'x': BG = 1/2[(x-9) + (3x-13)]
BG = 4x-22 / 2
BG = 3x-25
3x-25 / 1 = 4x-22 / 2
cross-multiply:
4x-22 = 2(3x-25)
4x-22 = 6x-50
-2x = -28
x = 14
to find 'BE': CB = BE
2x+4 = 7x-1
-5x = -5
x = 1
BE = 7(1) - 1
BE = 6

Lines c and d are perpendicular. The equation of line c is y=−12x+1. What is the equation of line d?
Answers
Answer:
y = 1/12x + b
Step-by-step explanation:
So lines that are perpendicular have a negative reciprocal slope.
If line c has a slope of -12, then line d has a slope of 1/12
So y = 1/12x + b would be perpendicular to c, where b is a constant

Answers
Answer:
My answer:(K-6) (K+4)
Step-by-step explanation:Note:If this is wrong my apologies.Sorry if this doesn't help.
All i did to solve this math problem is that i factor k^2-2k-24 by using the AC method.
The factors of the quadratic equation by applying the factorization method are (k + 4) and (k - 6)
Used the concept of the quadratic equation which states that,
An algebraic equation with the second degree of the variable is called a Quadratic equation.
Given that,
The quadratic equation,
k² - 2k - 24
Now, apply the factorization method in the above equation,
k² - 2k - 24
k² - (6 - 4)k - 24
k² - 6k + 4k - 24
k (k - 6) + 4 (k - 6)
Therefore, the factors are,
(k + 4) (k - 6)

Question 6 :
Janelle sells sandwiches She spends
$270 per sandwich on Ingredients and
then adds a 110% markup. What is the
selling price of one sandwich?
Answers
Answer:
$5.67
Step-by-step explanation:
$5.67
Markup refers to the amount added to the cost price to cover overheads and profit. So for example a 50% markup on a $10 product would mean adding 50% of $10 onto the sale price. As fractions can be written as decimals (50% = 0.5) and we are adding on the amount of markup to the initial cost we can also phrase this as 10 x 1.5 = 15
For your question, the markup would become 1.1 and the initial cost is 2.7, remembering we must add 1 to the markup to cover the initial cost
2.7 x 2.1 = 5.67

Add 1 to both sides
4x < 12
Divide both sides by 4
x < 3
x is less than 3
Answer:
x < 3
Step-by-step explanation:
Isolate the variable, x. Treat the < sign as an equal sign, what you do to one side, you do to the other.
Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, add 1 to both sides of the equation:
4x - 1 (+1) < 11 (+1)
4x < 11 + 1
4x < 12
Next, divide 4 from both sides of the equation:
(4x)/4 < (12)/4
x < 12/4
x < 3
x < 3 is your answer.

Joanne deposits $4,300 into a one-year CD at a rate of 2.3%, compounded daily.
What is her ending balance after the year?
How much interest does she earn?
What is her annual percentage yield to the nearest hundredth of a percent?
Answers
Answer:
5k
Step-by-step explanation:
The interest accrued on the principal is $100.
Using the formula;
A = P( 1 + r/n)^nt
A - amount
P - Principal
r = rate
n = Number of times the interest is compound
t = time in years
Substituting values;
A = 4,300( 1 + 0.023/365)365 × 1
A = $4400
Interest = $4400 - $4,300 = $100
The annual percentage yield is obtained from;
APY=100 (1 + r/n )n – 1
APY=100 (1 + 0.023/365)^n - 1
APY= 100(0.023)
APY= 2.3 %

Middletown sponsors a two day conference for selected middle school students to study government. Suppose 20 student delegates will the attend the conference Each school should be represented fairly in relation to it's population.
Answers
Answer:
North Middle School = 10 students Central Middle School = 6 students South Middle School = 4 studentsStep-by-step explanation:
First calculate the total number of students in all the schools:
= 618 + 378 + 204
= 1,200 students
Use this number to calculate the proportion of the total population that a school so that this can then be used to determine the proportion of the 20 delegates they should sent.
North Middle school:
= 618/1,200 * 20
= 10 students
Central Middle School:
= 378 / 1,200 * 20
= 6 students
South Middle School:
= 204/1,200 * 20
= 4 students
