12 r - 18 = 13 r + 18

m= 2.5x is the equation you want to use, hope this helped! <3

Answer:

The correct answer is x10= 25

Step-by-step explanation:

First we must analyze the information we have:

We know that Luis spent 25 minutes blowing up 10 balloons.

What we want to find out is how many minutes it took to blow up one.

So, if for 25 minutes -------- it blew up 10 balloons

         for x minutes -------------- blew up 1 ballon.

If we cross the terms the equation would be as follows:

x.10 = 25.1

And we just have to solve it:

x = 25/10

x = 2.5

The correct answer is that it took 2.5 minutes to blow up a balloon.

Answer:

A.Put each person's name on a separate piece of paper in a bag. Randomly draw the winning name; and D.Roll a number cube. If it lands on an even number, Roddy wins. If it lands on an odd number, Scott wins.

Step-by-step explanation:

In order for it to be a fair decision, both boys have to have an equal chance of being selected.

For choice A, drawing their names from a bag, both names are equally likely to be chosen; that makes this fair.

For choice B, there is 1 way to get both heads when flipping a coin.  There are 2 ways to get heads and tails when flipping a coin.  This gives Scott a greater chance, so this is not fair.

For choice C, there are 2 ways to get a 1 or a 2.  There are 4 ways to get anything else.  This gives Scott a greater chance, so this is not fair.

For choice D, there are 3 even numbers and 3 odd numbers.  Both boys have an equal chance, so this is fair.

Answer:

it a and d on any where

Step-by-step explanation:

The difference between the two square roots of a whole number cannot be about 5.3.

The difference between the two square roots of a whole number can be expressed as:

sqrt(x) - sqrt(x) = 5.3

Since the square root of a number multiplied by itself gives the number, we can rewrite the equation as:

x - x = 5.3

This simplifies to:

0 = 5.3

However, this is not possible, as it would mean that 0 is equal to a non-zero value. Therefore, there is no whole number that satisfies the given condition.

Answer: Number of white socks Fran has =18

Number of white socks Mia has = 9

Step-by-step explanation:

Since we have given that

Fran buys socks in such a way that it contains nine pairs of white socks for every three pairs of blue socks i.e.

Ratio becomes

[tex]9:3=3:1[/tex]

Similarly,

Mia buys socks and packages in such a way that it contains two blue pairs for every one white pair

So, ratio becomes

[tex]2:1[/tex]

Now, from the case of Fran, we have given that she has 6 pairs of blue socks .

So, we get that

[tex]\frac{1}{4}\times x=6\\=x=24\\\\\text{So, number of white socks becomes }=\frac{3}{4}\times 24=\frac{72}{4}=18[/tex]

Similarly,

From the case of Mia , we have given that she has 6 pairs of blue socks .

we get that

[tex]\frac{2}{3}\times y=6\\y=9\\\\\text{So, number of white socks Mia has }=\frac{1}[3}\times 9=3[/tex]

So, Number of white socks Fran has =18

Number of white socks Mia has = 9

Final answer:

Fran would have bought 18 white pairs of socks and Mia would have bought 12 white pairs, given their purchase of 6 pairs of blue socks and based on their respective ratios of white to blue socks in a package.

Explanation:

To answer the student's question, we must understand the concept of ratios. Fran buys socks in a package with a ratio of 9 white pairs to 3 blue pairs. Mia buys socks in a package with a ratio of 2 blue pairs to 4 white pairs. If each girl bought six pairs of blue socks, we'll calculate how many white socks they would have bought by setting up a proportion corresponding to each of their packages' ratios.

For Fran: The ratio 9:3 simplifies to 3:1 (since for every three pairs of white socks, there is one pair of blue socks). So for every blue sock pair, there are three white. Therefore, if Fran buys 6 blue pairs, she would buy 6 * 3 = 18 white pairs.

For Mia: The ratio 2:4 simplifies to 1:2. So for every two pairs of white socks, there is one pair of blue socks. Therefore, if Mia buys 6 blue pairs, she would buy 6 / 1 * 2 = 12 white pairs.

x=2

(2X-8.6)/2=-2.3

multiply both sides by 2 to gte rid of the denominator

2x-8.6= -4.6

add 8.6 to both sides

2x=4

x=2

Isolate the x. Note the equal sign. What you do to one side, you do to the other.

First, multiply 2 to both sides

(2x - 8.6)/2(2) = -2.3(2)

2x - 8.6 = -4.6

Isolate the x. First, add 8.6 to both sides

2x - 8.6 (+8.6) = -4.6 (+8.6)

2x = -4.6 + 8.6

2x = 4

Next, to isolate the x, divide 2 from both sides

2x/2 = 4/2

x = 4/2

x = 2

2 is your answer for x

~Rise Above the Ordinary

Note the equal sign. What you do to one side, you do to the other.

Also, remember to do the opposite of PEMDAS.

First, subtract 6 from both sides

-2x + 6 (-6) = -20 (-6)

-2x = -26

Next, isolate the x. Divide -2 from both sides

(-2x)/-2 = (-26)/-2

x = -26/-2

x = 13

13, or (B) is your answer

we are asked to write an expression that uses partial products to multiply 8 and 64. In this case, we can break 8 into 2 x4 and 64 into 8x8. In this case, multiplying these factors equal to 512. Any factors will do actually since it will yield the same product.

The equation of the line in point slope form that passes through the two given points is y + 8 = 3x - 24.

The equation of the line in point slope form that passes through the two given points (8,-8) and slope 3 can be found using the formula y - y1 = m(x - x1), where (x1, y1) represents one of the given points and m represents the slope. Plugging in the values, we get y - (-8) = 3(x - 8). Simplifying this equation gives us y + 8 = 3x - 24. This is the equation of the line in point slope form.

Elena needs to calculate the total surface area of her cubic jewelry box to know how much blue paint to buy. The surface area is 96 square inches, based on an edge length of 4 inches. The actual amount of paint depends on the paint's coverage rate.

Each side of a cube has an area calculated by squaring the length of an edge. Since all sides are equal for a cube, the total surface area is 6 times the area of one face.

To find the area of one face: Area = edge length × edge length = 4 inches × 4 inches = 16 square inches.

Therefore, the total surface area of the jewelry box is 16 square inches × 6 = 96 square inches.

To determine how much blue paint Elena will need, we use the total surface area of 96 square inches. The amount of paint required typically depends on the coverage rate of the paint, which is usually mentioned on the paint container. Elena should look for this information to buy the correct amount of blue paint needed to cover 96 square inches.

By solving a linear equation, conclude that the measure of our angle is 55 degrees.

We know that two angles A and B are supplementary if their measures add up to 180°, then:

A + B  = 180°

And two angles are complementary if their measures add up to 90°.

A + B = 90°

Now, let's define A as our angle, B as the supplement, and C as the complement, then we can write:

A + B = 180°

A + C = 90°

We know that B is 20° more than 3 times the complement, then we can write:

B = 20° + 3*C

Usuing the two equations above we can rewrite:

B = 180° - A

C = 90° - A

Replacing that above, we get:

(180° - A) = 20° + 3*( 90° - A)

We need to solve this linear equation for A.

180° - A = 20° + 270° - 3*A

3*A - A = 20° + 270° - 180°

2*A = 110°

A = 110°/2 = 55°

We conclude that the measure of our angle is 55 degrees.

Well let's remember the place values in order to solve this

(Notice how the 3 is in the thousands place)

Now lets separate these place values from the number shown in the question

700,000 + 40,000 + 3,000 + 100 + 80 + 2

As we see up there ^. The thousands place shows the number 3,000

3,000 is your answer

If you break it down the 3 it is in the thousands place. You take all the numbers after 3 and make them 0’s and you’ll find that the value of 3 is 3,000.
