For z and -1.9 to be additive inverses, they must sum up to zero. Consequently, z should be 1.9, and both -1.9 and z (=1.9) placed on a number line would reflect their locations relative to zero. The sum of -1.9 and 1.9 would equal zero.

In Mathematics, additive inverses are two numbers that add up to give zero. If the numbers z and -1.9 are additive inverses, this means that when added together, they produce the sum of zero. Therefore, z should be the opposite of -1.9, 1.9 on the number line.

The number -1.9 would appear on the left-hand side of the zero because it is a negative number. The number z (=1.9) would appear on the right-hand side of the zero because it's positive. According to the definition of additive inverses, the sum of these two numbers (-1.9 and 1.9) would be zero. So, 'Sum' would also be zero on the number line.

To solve (7 × 10^5) + (2 × 10^3), you add the numbers in expanded form (700,000 + 2,000 = 702,000) and then convert to scientific notation (7.02 × 10^5). The correct answer is 7.02 × 10^5.

To find the sum of (7 × 10^5) and (2 × 10^3), you first write out these numbers in their expanded form:

Adding the two numbers:

700,000 + 2,000 = 702,000

Now, we need to convert 702,000 back into proper scientific notation. To do this:

Therefore, 702,000 is 7.02 × 10^5 in scientific notation, which makes the correct answer:

(7 × 10^5) + (2 × 10^3) = 7.02 × 10^5,

so the correct choice is D) 7.02 × 10^5.

The value of x is 1, and the length of segment BC is 5 units.

If point B is between points A and C, then we can use the segment addition postulate to relate the lengths of segments AB, BC, and AC.

According to the segment addition postulate, the sum of the lengths of two segments that form a larger segment is equal to the length of the larger segment. In this case, we have:

AB + BC = AC

We're given that AB = 3x, BC = 5x, and AC = 8. Substituting these values into the equation:

3x + 5x = 8

Combine like terms:

8x = 8

Now, divide both sides by 8 to solve for x:

x = 8 / 8

x = 1

So, x is equal to 1.

Now that we know the value of x, we can find the length of segment BC:

BC = 5x

BC = 5 * 1

BC = 5

for such more question on length

Final answer:

To find out how many pounds of Earl Grey tea and Orange Pekoe tea are required to make 400 pounds of the new blend, set up a system of equations based on the given information. Solve the equations to find the values of x and y.

Explanation:

To find out how many pounds of Earl Grey tea and Orange Pekoe tea are required to make 400 pounds of the new blend, we can set up a system of equations based on the given information.

Let x be the number of pounds of Earl Grey tea, and let y be the number of pounds of Orange Pekoe tea.

We know that the selling price of the new blend is $3.50 per pound, and there is to be no difference in revenue from selling the new blend versus selling the other types.

This means that the revenue from selling the Earl Grey tea and Orange Pekoe tea separately should be the same as the revenue from selling the new blend.

The revenue from selling the Earl Grey tea is 4x, and the revenue from selling the Orange Pekoe tea is 2y. So we have the equation 4x + 2y = 3.50 ×400.

We also know that the total weight of the new blend is 400 pounds, so we have the equation x + y = 400.

We can solve these two equations to find the values of x and y.

The gas mileage of Ms. Gonzalez's car is 48 miles per gallon. Therefore, the correct answer is B. 48 miles per gallon.

To find the gas mileage of Ms. Gonzalez's car, we divide the total distance travelled by the amount of gas consumed.

Given:

- Total distance travelled = 420 miles

- Amount of gas consumed = 8 3/4 gallons

To find the gas mileage, we divide the total distance by the amount of gas:

[tex]\[ \text{Gas mileage} = \frac{\text{Total distance}}{\text{Amount of gas consumed}} \][/tex]

[tex]\[ \text{Gas mileage} = \frac{420}{8 \frac{3}{4}} \][/tex]

To divide by a mixed number, we first convert it to an improper fraction:

[tex]\[ 8 \frac{3}{4} = \frac{(8 \times 4) + 3}{4} = \frac{32 + 3}{4} = \frac{35}{4} \][/tex]

Now, we can perform the division:

[tex]\[ \text{Gas mileage} = \frac{420}{\frac{35}{4}} \][/tex]

[tex]\[ \text{Gas mileage} = \frac{420 \times 4}{35} = \frac{1680}{35} \][/tex]

[tex]\[ \text{Gas mileage} = 48 \text{ miles per gallon} \][/tex]

Rounded to the nearest mile per gallon, the gas mileage is 48 miles per gallon.

So the correct answer is: B. 48 miles per gallon.

Complete Correct Question:

Ms. Gonzalez hybrid car can travel 420 miles on 8 3/4 gallon of gas. What is the gas mileage on the car? Round to the nearest mile per gallon, if necessary .

A. 43 miles per gallon

B. 48 miles per gallon

C. 49 miles per gallon

D. 50 miles per gallon

Answer: 5 units.

Step-by-step explanation:

Given : Line segment EF has a length of 5 units.    (1)

It is translated 5 units to the right on a coordinate plane to obtain line segment E'F'.

We know that a translation is a rigid transformation that produces images by moving it by some distance in a particular direction . It preserves the shape and the side-length of the figure.

Thus, The length of E'F'=EF  [∵E'F' is the image produced after translation of EF]

⇒ Length of E'F'= 5 units.    [From (1)]

the inequality "2 more than k is greater than -3" can be represented as:[tex]\[ k + 2 > -3 \][/tex]

To translate the phrase "2 more than k is greater than -3" into an inequality, we can follow these steps:

1. Identify the expression "2 more than k."

2. Write the expression as an inequality where it is greater than -3.

Step 1: "2 more than k" translates to (k + 2).

Step 2: Since "2 more than k" is greater than -3, we write the inequality:

[tex]\[ k + 2 > -3 \][/tex]

So, the inequality "2 more than k is greater than -3" can be represented as:[tex]\[ k + 2 > -3 \][/tex]

The multiplier for 3/10 = 15/50 is 5 after multiplying by 5 on the numerator and denominator.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

The fraction is 3/10

And the fraction of 3/10 is equivalent to the 15/50

3/10 = 15/50

On the left side multiply by 5 on the numerator and denominator.

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division.

= (3/10)(5/5)

= 15/50

Thus, the multiplier for 3/10 = 15/50 is 5 after multiplying by 5 on the numerator and denominator.
