Determine the value of the variable that makes the equation true.
b + (-8.3) = 0

Plan B is less expensive than Plan A when you use at least 25

Inequalities can simply be defined as mathematical expressions in which both or two sides of the expression are not equal.

From the information given, we have that;

Now, let's write the inequality that represents Plan B < Plan A

If Plan B < Plan A

Then,

0. 19m + 6. 00 <  0. 25m

Let's simply the inequality

6. 00 < 0. 25m - 0. 19m

0. 06m < 6. 00

Make 'm' the subject

m < 6. 00/ 0. 06

m < 100

Thus, Plan B is less expensive than Plan A when you use at least 25

Applying the knowledge of fractions, the number of pounds of vegetables required to prepare 1/3 bowl of salad is: 1¼ pounds.

In solving this problem, we would apply our knowledge of fractions as explained below.

One bowl of salad needs 3¾ pounds of vegetables

Let the number of pounds if vegetables needed for ⅓ bowl be represented as x. Therefore, we would have the following proportion:

1 bowl = 15/4 pounds of vegetables [i.e. 3¾]

⅓ bowl = x

Thus:

1/15/4 = ⅓/x

1/1 × 4/15 = 1/3 × 1/x

4/15 = 1/3x

Cross multiply

4(3x) = 1(15)

12x = 15

Divide both sides by 12

12x/12 = 15/12

x = 15/12

x = 5/4

x = 1¼ pounds

Therefore, applying the knowledge of fractions, the number of pounds of vegetables required to prepare 1/3 bowl of salad is: 1¼ pounds.

Answer:

15 Gigabites

Step-by-step explanation:

The closest you can can get to is $70, so by adding five in the times tables it gets you up to 15 x 5 which is 70.

Answer:

(4,13)

Step-by-step explanation:

Set the 2 equations equal to each other and solve for x.

5x - 7 = 2x + 5  Subtract 2x from both sides

3x - 7 = 5  Add 7 to both sides

3x = 12  Divide both sides by 3

x = 4

Now plug 4 back into either of the original 2 equations to find y.

y = 5x -7

y= 5(4) -7

y = 20 -7

y= 13

The arithmetic sequence is 7,14,21,28,35,48

In an arithmetic progression (AP) sequence of numbers, the difference between any two consecutive integers is always the same. It is also known as an arithmetic sequence.

There are two definitions for an arithmetic sequence. Each term in an arithmetic sequence is created by adding a predetermined number (positive, negative, or zero) to its preceding term. It is a "series where the differences between every two following terms are the same."

Given,

first term, a = 7

common difference d = 7

n = 2

a+(n-1)d = 7+( 2 - 1 )7

= 7 + 7

= 14

n = 3

a+(n-1)d = 7+(3-1) 7

= 7+14

= 21

n = 4

a+(n-1)d = 7+(4-1) 7

= 7+ (3)7

= 28

n = 5

a+(n-1)d = 7+( 5-1 ) 7

= 7+ (4)7

= 35

n = 6

a+(n-1)d = 7+( 6-1 ) 7

= 7+ (5)7

= 42

the five terms are 7,14,21,28,35,48.

According to the solving it is proved that DE is parallel to BC.

Coordinates are numerical lengths or angles that uniquely identify points on two-dimensional (2D) or three-dimensional (3D) surfaces ( 3D ). Mathematicians, physicists, and engineers employ a variety of coordinate systems.

In-parallel refers to something that is the same distance as well as the direction away from something else. Two lines of individuals standing straight across from each other is an example of in-parallel. noun. 1. In-parallel means traveling the same direction and distance as something else.

To obtain the coordinates of each midpoint, use the midpoint formula.

(x, y) = (½ (x₁ + x₂), ½(y₁ + y₂))

Coordinates of D:

(x, y) = (½ (4 + 2), ½(6 + -2))

(x, y) = (3, 2)

Coordinates of E:

(x, y) = (½ (4 + -2), ½(6 + -4))

(x, y) = (1, 1)

Slope of DE:

m = Δy / Δx

m = (2 − 1) / (3 − 1)

m = 1/2

Slope of BC:

m = Δy / Δx

The probability of randomly drawing the chip number 564 is 1 / 713 or 0.0014

Probability is used to determine the odds that a random event would happen. The odds that the event would happen is a distribution that lies between 0 and 1.

If it is certain that the event would occur, the probability value would be 1. If  it is certain that the event would not occur, the probability value would be 0. If it is equally likely that the event would happen or not happen, the probability value would be 0.5.

The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.

Since m(n(x)) = n(m(x)) = x, then m(x) and n(x) are inverse functions

The inverse of a function is a function that can reverse into another function.

If we have function f and g, and f f(x) = y, then g is the inverse of f if and only if g(y) = x

Also, if f is a function f⁻¹ is the inverse of x and ff⁻¹(x) = f⁻¹f(x) = x

Given the functions m(x) = x³ - 5 and n(x) = ∛(x + 5)

If m(x) and n(x) are inverse, then m(n(x)) = n(m(x)) = x

So, we proceed as follows

m(x) = x³ - 5

m(n(x)) = (∛(x + 5))³ - 5

m(n(x)) = x + 5 - 5

m(n(x)) = x + 0

m(n(x)) = x

Also,

n(x) = ∛(x + 5)

n(m(x)) = ∛(x³ - 5 + 5)

n(m(x)) = ∛(x³ - 0)

n(m(x)) = ∛(x³)

n(m(x)) = x

Since m(n(x)) = n(m(x)) = x, then m(x) and n(x) are inverse functions

Based on the money earned by Kaleigh's aunt from Wheels Around Town, the relationship between miles and money earned is proportional.

In a proportional relationship, the rate of increase or decrease in x should be equivalent to the rate of increase or decrease in y. This rate should be constant through the entire distribution.

The equation of the line should take the form:
y = mx

There should be no y-intercept.

The slope is:
