Step-by-step explanation:

pls mark this brainliest im trying to lvl up

The two numbers that add up to 21 but subtract to 5 are 13 and 8.

The two numbers are 13 and 8.

To find the numbers, set up the system of equations:
x + y = 21 (Equation 1)
x - y = 5 (Equation 2)

Adding Equation 1 and Equation 2, you get 2x = 26, which means x = 13.

Substituting x back into Equation 1 gives y = 8.

Step-by-step explanation:

Dividing is multiplying by the reciprocal.

So 30 divided by 1/2

is like 30(2)=60

Then add 10 so 60+10=

70

The equivalent value of the expression "dividing 30 by half and adding ten"  is 70.

Given data:

Regarding step-by-step dissecting of "dividing 30 by half and adding ten"

Step 1 is to divide 30 in half.

A number is effectively divided by 1/2 when we divide it in half. A fraction's reciprocal is what you multiply by when you divide by it. 1/2 has a reciprocal of 2/1, or only 2.

As a result, multiplying 30 by 2 is equivalent to dividing it in half:

To make the equation simpler:

30 ÷ (1/2) = 30 × 2

= 60

Step 2: Ten-folding.

We obtain 60 by dividing 30 in half.

Now double the outcome by ten:

60 + 10 = 70

So, when you multiply 30 by half, add 10, and you get 70.

Hence, the equation is solved and the solution is 70.

Which ratios can be used to find the scale factor.

Solution:

Scale factor is the ratio of comparing the corresponding sides of two figures.

Option A:

[tex]$ \text {Scale factor} =\frac{\text { Enlarged }}{\text { Original }}=\frac{6.5}{3.25}$[/tex]

Length of enlarged side = 6.5

Length of original side = 3.25

It is correct.

Option B:

[tex]$\text {Scale factor}= \frac{\text { Enlarged }}{\text { Original }}=\frac{3.25}{6.5}$[/tex]

3.25 is the length of original figure. But here it is mentioned in enlarged.

So, it is not correct.

Option C:

Width of enlarged side = 3

Width of original side = 1.5

It is correct.

Option D:

Step-by-step explanation:

Answer:

Must determine the LCD.  Think:  what is the smallest (least) number divisible by both 30 and 20?  You could, of course, just multiply 30 and 20, obtaining 600, but that would not be the LCD.

Note that 30 and 20 share the common factor 10.  Multiplying 3 and 2 together produces 6.  The LCD is 10*6 = 60.  Note that both 30 and 20 divide into 60 with no remainder.

Then  19/30  = 2(19) / 2[30]  = 38/60, and 

13/20 = 3(13) / 3[20]  = 39/60.

Which is larger, 38/60 or 39/60?

Write the relationship between these 2 numbers using the appropriate inequality operator.

Step-by-step explanation:

The fractions 13/30 and 9/20, when rewritten with a common denominator, are 26/60 and 27/60, respectively.

To rewrite the fractions 13/30 and 9/20 with a common denominator, we need to find the least common multiple (LCM) of the denominators, which is the smallest multiple that both 30 and 20 share.

The prime factorization of 30 is 2 * 3 * 5, and the prime factorization of 20 is 2 * 2 * 5. To find the LCM, we take the highest power of each prime factor that appears in either number:

LCM(30, 20) = 2 * 2 * 3 * 5 = 60

Now, let's rewrite the fractions with the common denominator of 60:

13/30 = (13/30) * (2/2) = (13 * 2) / (30 * 2) = 26/60

9/20 = (9/20) * (3/3) = (9 * 3) / (20 * 3) = 27/60

So, the fractions 13/30 and 9/20, when rewritten with a common denominator, are 26/60 and 27/60, respectively.

Where k is the constant of proportionality.

Let us consider any of the coordinate from the graph and substitute in the formula.

Consider the coordinate (4,40) and substitute in the above formula.

Answer:

8000 litres

Step-by-step explanation:

⅓ (4 × 2.5 × 2.4)

= 8 m³

1 m² = 1000 litres

8 m³ = 8000 litres

The volume of water in the tank in litres can be found by calculating one third of the capacity of the tank in cubic metres and then multiplying that by 1000. We represent this as 1000X/3 litres, where X is the total capacity of the tank in cubic metres.

To solve this problem, we firstly need to know the total capacity of the tank in cubic metres. Since we don't have this specific information in the question, let's call this capacity as 'X' cubic metres.

One third of the tank is filled with water, so the volume of water in the tank is one third of X, which is (1/3) * X cubic metres. We know that 1 cubic metre is equivalent to 1000 litres, therefore, the volume of the water in the tank in litres is (1/3) * X * 1000, which simplifies to 1000X/3 litres.

The first term is 128

Step-by-step explanation:

The common ratio of the geometric series is given as:

[tex]r = \frac{1}{4} [/tex]

The sum of the first 4 term is 170.

The sum of first n terms of a geometric sequence is given b;

[tex]s_n=\frac{a_1(1-r^n)}{1-r}[/tex]

We put the common ratio, n=4 and equate to 170.

[tex]\frac{a_1(1-( \frac{1}{4} )^4)}{1- \frac{1}{4} } = 170[/tex]

Simplify:

[tex]\frac{a_1(1- \frac{1}{256} )}{ \frac{3}{4} } = 170[/tex]

[tex] \frac{255}{256} a_1 = \frac{3}{4} \times 170[/tex]

[tex]\frac{1}{256} a_1 = \frac{1}{2} [/tex]

Answer:

Step-by-step explanation:

If the gardener bought more white than pink, that could mean he could have bought 12 white and one pink, 11 white and 2 pink, 10 white and 3 pink, 9 white and 4 pink, 8 white and 5 pink, or 7 white and 6 pink.

If you plug in the numbers, for example with 7 and 6, that would equal $53, which is not correct. Continue to do this with all of the answers.

With 8 white roses and 5 pink roses, this would equal $55 (40+15), which is the answer.

By solving form expressions the gardener bought 5 pink plants.

In mathematics, an expression is a combination of one or more numbers, variables, constants, and operators, which when evaluated, produce a value. Expressions can include mathematical symbols such as addition, subtraction, multiplication, division, exponents, roots, logarithms, and trigonometric functions.

Let's use algebra to solve this problem.

Let's assume that the gardener bought x pink plants and y white plants. We know that:

The gardener bought 13 plants in total: x + y = 13

The gardener spent $55: 3x + 5y = 55

The gardener chose more white plants than pink: y > x

We can use the first equation to solve for x in terms of y:

x = 13 - y

Now we can substitute this into the second equation:

3(13 - y) + 5y = 55

Simplifying and solving for y:

39 - 3y + 5y = 55

2y = 16

y = 8

So the gardener bought 8 white plants. To find out how many pink plants were bought, we can substitute this value into the first equation:

x + y = 13

x + 8 = 13

x = 5

So the gardener bought 5 pink plants.
