Answer:
1. Multiply (2) by 2 to eliminate the x-terms when adding
2. Multiply (2) by 3 to eliminate the y- term
Step-by-step explanation:
Use this system of equations to answer the questions that follow.
4x-9y = 7
-2x+ 3y= 4
what number would you multiply the second equation by in order to eliminate the x-terms when adding the first equation?
4x-9y = 7 (1)
-2x+ 3y= 4 (2)
Multiply (2) by 2 to eliminate the x-terms when adding the first equation
4x-9y = 7
-4x +6y = 8
Adding the equations
4x + (-4x) -9y + 6y = 7 + 8
4x - 4x - 3y = 15
-3y = 15
y = 15/-3
= -5
what number would you multiply the second equation by in order to eliminate the y- term when adding the second equation?
4x-9y = 7 (1)
-2x+ 3y= 4 (2)
Multiply (2) by 3 to eliminate the y- term
4x - 9y = 7
-6x + 9y = 12
Adding the equations
4x + (-6x) -9y + 9y = 7 + 12
4x - 6x = 19
-2x = 19
x = 19/-2
= -9.5
x = -9.5

Delta Company produces a single product. The cost of producing and selling a single unit of this product at the company's normal activity level of 88,800 units per year is: Direct materials $ 1.50 Direct labor $ 3.00 Variable manufacturing overhead $ 0.50 Fixed manufacturing overhead $ 4.45 Variable selling and administrative expenses $ 1.30 Fixed selling and administrative expenses $ 2.00 The normal selling price is $21.00 per unit. The company's capacity is 112,800 units per year. An order has been received from a mail-order house for 2,000 units at a special price of $18.00 per unit. This order would not affect regular sales or the company's total fixed costs
Answer:
The company should accept the special offer because it increases income by $23,400.
Step-by-step explanation:
Giving the following information:
Variable costs:
Direct materials $1.50
Direct labor $3.00
Variable manufacturing overhead $0.50
Variable selling and administrative expenses $1.30
Total variable cost= $6.3
An order has been received from a mail-order house for 2,000 units at a special price of $18.00 per unit.
Because it is a special offer and there is unused capacity, we will not take into account the fixed costs:
Effect on income= number of units*unitary contribution margin
Effect on income= 2,000* (18 - 6.3)
Effect on income= $23,400 increase
The company should accept the special offer because it increases income by $23,400.

What is the mass of an object that has a density of 8 g/cm3 and a volume of 64 cm3
Answer:
Step-by-step explanation:
multiply 64 and 8
512
The required mass of an object is 512g.
Given that,
The density of 8 g/cm3 and a volume of 64 cm3,
The mass of the object is to be determined.
Volume is defined as the ratio of the mass of an object to its density.
What is simplification?The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.
Here,
Mass = density * volume
Mass = 8 * 64
Mass = 512 g
Thus, the required mass of the object has density of 8 g/cm3 and a volume of 64 cm3.

The area of a rectangular patio is 14 5/ 8 square meters. The width of the patio is 3 1/4 meters. What is the length? Enter your answer as a mixed number in simplest form. The length of the patio is meters.
Answer:
4 1/2 m
Step-by-step explanation:
Area of the patio = 14 5/8 m²
Width = 3 1/4m
Length = ?
Area of the patio = length ×width
Substitute
14 5/8 = 3 1/4 × L
Convert to improper fractions
117/8 = 13/4 L
Cross multiply
8 ×13L = 117×4
2 ×13L= 117
2×L = 9
2L = 9
L = 9/2
L. = 4 1/2 m (in mixed fraction)

Ray Flagg took out a 60-month fixed installment loan of $12,000 to open a new pet store. He paid no money down and began making monthly payments of
$221.
Ray's business does better than expected and instead of making his
30th
payment, Ray wishes to repay his loan in full. Complete parts a) through
c).
Answer:
Since the question is incomplete, I looked for similar questions:
a) determine apr of installment loan
b) how much interest will Ray save by paying off the loan early
c) what is the total amt due to pay off the loan?
a) first we will determine the effective rate:
PV annuity factor = loan / monthly payment
PV annuity factor = $12,000 / $221 = 54.2986
Using an annuity table, knowing that the number of periods is 60, we can see that the interest rate is 0.333%.
APR = 0.333% x 12 = 4%
b) I prepared an amortization schedule to determine Ray's balance after the 29th payment.
After the 29th payment, Ray's balance will be $6,498.54
in order to pay off the debt completely, he needs to pay $6,498.54 + $22.32 in interests = $6,520.86.
He will be able to save $331 in interests
c) $6,520.86
