Solve for x in the equation you chose.
x =
Incorrect answer:
8.3
Answer:
x + 2.6 = 10.4
x = 7.8
Step-by-step explanation:
If 2.6 liters are added to x liters with the result that 10.4 liters then exist, the model is ...
2.6 +x = 10.4 . . . . . . . 2.6 added to x gives 10.4
The commutative property of addition lets you rewrite this to ...
x +2.6 = 10.4
__
Subtracting 2.6 from both sides of the equation gives its solution:
x +2.6 -2.6 = 10.4 -2.6
x = 7.8
Subtract six times the quantity 3a + 12b - 4c from eight times the sum of the quantities 14a +
70 and 5b - 12c
Answer:
94a - 32b - 72c + 560
Step-by-step explanation:
First get the product of 6(3a + 12b - 4c) = 18a + 72b - 24c.
Second get the sum of 14a + 70 and 5b - 12c = 14a + 5b - 12c + 70 then multiply by 8 and the product is 112a + 40b - 96c + 560. Subtract the first product from the 2nd product to get the final answer

What is p(A)?
The probability model shows the distribution of people of age 20 to 39 years
The value of the probability P(A) is 0.631
How to determine the probability, P(A)From the question, the notation P(A) represents the probability that a person is either 20-24 years old or is married
From the table, we have the following parameters:
P(20-24) = 0.227 + 0.027 + 0.006 = 0.26P(Married) = 0.027 + 0.086 + 0.137 + 0.148 = 0.398P(20-24 and Married) = 0.027The probability, P(A) is then calculated as:
P(A) = P(20-24) + P(Married) - P(20-24 and Married)
Substitute known values
P(A) = 0.26 + 0.398 - 0.027
Evaluate the expression
P(A) = 0.631
Hence, the value of the probability P(A) is 0.631

Step-by-step explanation:
Angles 1 and 3 are vertical angles, so are congruent. The same can be said of angles 2 and 4. Each odd-numbered angle is supplementary to each even-numbered angle.

Assume a corporate bond pays a 5 percent coupon and matures in ten years. What will be the change in the current price of this bond if market interest rates increase from 5 to 5.5 percent?
The change in the current price of the bond when the market interest rates increase from 5% to 5.5% is a fall in the price of the bond.
What happens to bond prices with increased market interest rates?The attractiveness of bonds occurs when the interest rates fall. This fall drives up demand for bonds with fixed interest rates and the increasing demand causes bond prices to rise.
This implies that when interest rates rise, investors do not prefer the lower fixed interest rate paid by a bond. The reduced demand for bonds results in their declining prices.
Thus, when interest rates rise, bond prices fall and when interest rates fall, bond prices rise.

What is the area of the region in the first quadrant bounded on the left by the graph of x=y^2/2 and on the right by the graph of x=3y−4 for 2≤y≤4 ?
The area of the region is -2/3 square units
The area bounded by the regionSince the region is bounded on the left by x = y²/2 and on the right by x = 3y - 4 for 2 ≤ y ≤ 4, the area of the region is given by
[tex]A = \int\limits^4_2 {\frac{y^{2}}{2} } \, dy - \int\limits^4_2 {(3y - 4)} \, dy \\[/tex]
Integrating, we have
A = [y³/6]₂⁴ - [3y²/2 - 4y]₂⁴
A = [4³/6 - 2³/6] - [3(4)²/2 - 4(4) - {3(2)²/2 - 4(2)]}]
A = [64/6 - 8/6] - [3(16)/2 - 16 - {3(4)/2 - 8]}]
A = [64/6 - 8/6] - [3(16)/2 - 16 - {3(4)/2 - 8]}]
A = [64/6 - 8/6] - [3(8) - 16 - {3(2) - 8]}]
A = [(64 - 8)/6] - [3(8) - 16 - {3(2) - 8]}]
A = [56/6] - [24 - 16 - {6 - 8}]
A = [56/6] - [8 - {-2}]
A = [56/6] - [8 + 2]
A = [56/6] - [10]
A = 56/6 - 10
Taking the L.C.M, we have
A = (56 - 10 × 6)/6
A = (56 - 60)/6
A = -4/6
A = -2/3 square units
So, the area of the region is -2/3 square units
