Answer:

15 (3+1)

Step-by-step explanation:

Hope this helps :)

The solution is 15 + 45 = 15 ( 1 + 3 )

The greatest common divisor of 15 and 45 is 15 and the equation is simplified as 15 + 45 = 15 ( 1 + 3)

What is Greatest Common Factor?

The Greatest Common Divisor is the highest number that divides exactly into two or more numbers. It is also expressed as GCF

Given data ,

Let the equation be represented as A

Now , the value of A is

15 + 45 = a ( x + y )

Let the first number be A

Now , the value of A = 15

Let the second number be B

The value of B = 45

The factors of 15 = 1 , 3 , 5 , 15

The factors of 45 = 1 , 3 , 5 , 9 , 15 , 45

Now , the greatest factor of both 15 and 45 is the number 15

So , the equation will be simplified as

The value of a = 15

So ,

15 + 45 = 15 ( x + y )

The value of x + y = 4

And , x = 1 and y = 3

Substituting the values of x and y in the equation , we get

15 + 45 = 15 ( 1 + 3 )

Therefore , the value of a = 15

Hence , the greatest common divisor of 15 and 45 is 15

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

m>124

Step-by-step explanation:

33<m-91

-m<-91-33

-m<-124

m>124

Answer:

The answer is m > 124.

Step-by-step explanation

Firstly, you have to move the terms 33 < m - 91

Second, you have to calculate like - m < - 124

Then, you have to change the signs like - m < - 124

So, this solves the solution as m > 124.

Answer:

I belive Joe mowed 51 lawns and Marty mowed 23.

Step-by-step explanation:

Joe and Marty each mowed a total number of 15 lawns last week and they earned the same amount of money.

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

Joe earns a base amount of $15 and $8 per lawn.

Marty earns a base amount of $45 and $6 per lawn.

Let's suppose they both mow x number of lawns.

Then Joe's total income is given by:

$(15+8x)

And Marty's total income is given by:

$(45+6x)

As they earned the same amount of money, mathematically:

(15+8x) = (45+6x)

15 + 8x - 6x = 45 +6x - 6x   (subtract by 6x on both sides)

15 + 2x -15 = 45 -15              (subtract by 15 on both sides)

2x = 30

x = 15    (divide by 2 on both sides)

If we put x = 15 in Joe's total income expression, we get:

15+8×15 ⇒135

If we put x = 15 in Marty's total income expression, we get:

45+6×15 ⇒135

Thus, Joe and Marty each mowed a total number of 15 lawns last week and they earned the same amount of money.

The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.

With that being said, here is the order of the numbers from smallest to largest:

Step-by-step explanation:

You want to know the difference in miles per hour between a satellite traveling 45000 miles in 5 hours and one traveling 79200 miles in 18 hours.

The speed in miles per hour is the ratio of miles to corresponding hours. The difference in miles traveled in one hour will be ...

  A speed - B speed

  45000 mi/(5 h) - 79200 mi/(18 h) = 4600 mi/h

Explorer B travels 4600 fewer miles in an hour than Explorer A.

Answer:

The first graph is misleading because all it is is just bigger. However the second graph is the same 80 million ton barrel twice. This means that its 80 +80 which indeed is 160 million tons.

Step-by-step explanation:

The coordinates of vertices N'G'M'​ are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

From the given graph, N(-4, 6), M(-6, 2) and G(-2, 4).

Scale factor = \(2\frac{1}{2}\)

= 2.5

The reflection of point (x, y) across the x-axis is (x, -y).

Here, N(-4, 6)→(-4, -6)

M(-6, 2)→(-6, -2)

G(-2, 4)→(-2, -4)

Now, with scale factor 2.5, we get

(-4, -6)→2.5(-4, -6)→N'(-10, -15)

(-6, -2)→2.5(-6, -2)→M'(-15, -5)

(-2, -4)→2.5(-2, -4)→G'(-5, -10)

Therefore, the coordinates of vertices N'G'M'​ are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

Answer:

$2.15

Step-by-step explanation:

Let mango be m

Let avocado be a

10m + 12a = 23

5m + 4a = 10

Let's get rid of the mangos in the second equation

       10m + 12a = 23

-2 x (5m + 4a = 10)

Now we get:

10m + 12a =23

-10m -8a = -20

Add both the equations and we get:

4a = 3

a = $0.75

since we know that one avocado is for $0.75, we can use this value to find the cost of one mango.

5m + 4a = 10

5m + 4(0.75) = 10

5m + 3 = 10

5m = 7

m = 1.4

So, we now know that a mango cost $1.4

To find the cost of one mango and one avocado:

a + m = 0.75 + 1.4 = 2.15

Therefore, the cost of one mango and one avocado is $2.15

The required cost of one mango is 1.4 and cost of one avocado is 0.75.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

Given that,

Cost of ten mangos and twelve avocados is $23,

And cost of five mangos and four avocados is $10.

Let cost of mangoes be represented as M and cost of avocados be represented as A,

The equation can be written as,

10 M + 12 A = 23          (1)

5 M + 4 A = 10           (2)

By solving equation (1) and (2),

M = 7/5 = 1.4

N = 3/4 = 0.75

The cost of one mango is 1.4 and cost of one avocado is 0.75.

Since the angle is right, we know it is equal to 90 degrees.

Using the information provided, we can set up an equation.

50 + 5x + 15 = 90

Simplifying the equation, we get:

5x + 65 = 90

Subtracting 65 from both sides, we get:

5x = 25

Answer:

The Range Stays 48°.

Step-by-step explanation:\

Since the value 80.4° is not the highest and not the lowest value on the list, it does not change the range.

Hope this helps!

Answer:  B.  The range stays 48

Step-by-step explanation:

The largest answer is 105 and the smallest answer is 57.  The range is the range of numbers from smallest to largest so to find the range you subtract the largest and the smallest

Range = 105 - 57

Range = 48

The range will not change because if you put 80.4 in there, it's not the largest or smallest so it does not affect the range.
