The solution for the One-Variable Addition Equations is,

1: d = 0.6,  2:  k = 11,  and 3: y = 3.

When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."

There are both one-variable and two-variable linear equations.

Given 1: d  + 3.2 = 6.3 - 2.5

subtract 3.2 from both sides

d = 6.3 - 2.5 - 3.2

d = 0.6

2: 25 + k + 4(1/4) = 37

divide 4/4 = 1

25 + k + 1 = 37

k = 37 - 26

k = 11

3: 4(1/2) + y = 10(1/2)

so 4/2 = 2 and 10/2 = 5

2 + y = 5

y = 3

Hence d  = 0.6, k = 11,  and y = 3.

The fraction equivalent of 7/8 + 5/12 is 31/24

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.

Given here: Two fractions 7/8 and 5/12

Now sum of the two fractions are 7/8+5/12

We know When two or more fractions with different denominators are added together, then we cannot the numerators directly. Thus Make the denominators of the fractions same, by finding the LCM of denominators and rationalising them with LCM(8,12)=24

Thus, 7/8+5/12= 21+10  /24

                        = 31/24

Hence, The fraction equivalent of 7/8 + 5/12 is 31/24

Answer:

Fred spent $3.18 on brownies.

Answer:

5/12

Step-by-step explanation:

Find the LCM for denominators 3 and 4, this would be 12.

[tex]\frac{1*3}{4*3} = \frac{3}{12}[/tex]

[tex]\frac{1*4}{3*4} = \frac{4}{12}[/tex]

Add both fractions together:

3/12 + 4/12 = 7/12

Subtract 7 from 12 to find the remaining amount to make 12:

12 - 7 = 5

Therefore, the fraction that remains for other expenses is [5/12]

The value of x in the parallelogram is calculated to be 11

The value of x is solved using the property of a parallelogram which says that the opposite angles are equal

Applying this mathematically gives

7x - 2 = 75

7x = 75 + 2

7x = 77

Isolating x by dividing through by 7

7x / 7 = 77 / 7

x = 11

Step-by-step explanation: because the are skip count and adding the number every single time .

Two lines that are perpendicular to one another have a slope product that is negative one. If m1 and m2 are the slopes of the two lines, then m1.m2 = -1.

As a result, we may state that m1 = 4, which is the slope of this line.

As a result, m2 = -1/4 is the slope of the line perpendicular to this line.

Now, the 2nd line's general equation can be expressed as

y = (-1/4)x + c —— 1)

Since point (-12,4) is located on this line, we may solve for c by substituting y = -12 and x = 4 in the equation above.

We may finish the equation for the line perpendicular to the line y = 4x+3 once we know the value of c.

Answer:

121

Step-by-step explanation:

The formula for calculating the sum of interior angles is ( n − 2 ) × 180

so you have 5 sides n=5

so total is 3*180 = 540

there are 3 right angles = 3/90 = 270

so 540-270 = 270 = angle B+ angle C

so 6x+1 +8x-11 =270

14x-10 = 270

14 x =280

x=20

B =6x+1 =121

If you would like to have $500,000 when you retire in 30 years.
a. Amount earned  $2,322.76.

b. Total money  $2,322.76

c. Total interest earned $225,268.80

a) To calculate the amount you need to deposit each quarter to reach $500,000 in 30 years, you can use the formula:

P = A / (1 + r/n)^(nt)

P = $500,000 / (1 + 0.066/4)^(4 * 30)

P = $2,322.76

b) Total money

 Total money = $2,322.76 * 4 quarters/year * 30 years

Total money = $2,322.76

c) Total interest earned

Total interest earned = $274,731.20 - $500,000

Total interest earned = $225,268.80

31/6 or 5.167 feet of lumber was left.

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given,  Peter cut a piece of lumber 9 5/6 feet long from a piece that was 15 feet long.

Since the total length of wood is 15 feet

Thus,

The remaining wood = 15 - (9 5/6)

The remaining wood = 6 - 5/6

The remaining wood = 31/6

therefore, 31/6 or 5.167 feet of the lumber was left.

Step-by-step explanation:

To solve the inequality |2x + 5| < 2 - x, we need to split it into two cases:

When 2x + 5 > 0:

In this case, the absolute value is positive, so we can simplify the inequality as follows:

2x + 5 < 2 - x

Expanding the left side:

3x + 5 < 2

Subtracting 5 from both sides:

3x < -3

Dividing both sides by 3:

x < -1

So the solution for this case is x < -1.

When 2x + 5 < 0:

In this case, the absolute value is negative, so we can simplify the inequality as follows:

(2x + 5) < 2 - x

Expanding the left side:

-2x - 5 < 2 - x

Adding x to both sides:

-2x - 5 + x < 2

Combining like terms:

-x - 5 < 2

Adding 5 to both sides:

-x < 7

Dividing both sides by -1:

x > -7

So the solution for this case is x > -7.

Taking the union of the two solutions, we get:

-7 < x < -1.

This means that x is between -7 and -1, excluding -7 and -1.

7/3 in four different ways is 7/12

Division is the opposite of multiplication. If 3 groups of 4 make 12 in multiplication, 12 divided into 3 equal groups give 4 in each group in division. The main goal of dividing is to see how many equal groups are formed or how many are in each group when sharing fairly.

If 100 apples are to be shared by 20 girls equally. The number of apple each girl will get is 100/20 = 5 apples each.

Similarly to put 7/3 in four different ways we have to divide 7/3 by 4

C. a quadratic function with a negative value of a

Step-by-step explanation:

It is likely that a quadratic function with a negative value of a would be the best model for this data, as it would represent a parabolic shape that can accommodate a downward trend, followed by an upward trend, in the stock price. The value of "a" determines the direction of the parabola, with a negative value resulting in a downward-facing parabola, which is appropriate for a stock price that starts low and increases over time. This type of function would provide a good fit for the data, especially if there are fluctuations or ups and downs in the stock price over time.
