Mrs. Marina requires 5/2 or 2.5 cups of sugar to make  one and one half of the recipe.

What is proportion ?

A proportion is an equation based on the equality of two ratios.

Here it is given that :

A recipe requires 1 (2/3) cups of sugar.

That is 1 recipe requires = 1(2/3) cups of sugars

                                        = 5/3 cups of sugar

Now, Marina is going to make one and one half of the recipe and to find the sugar he needed we simply multiply 1(1/2) both the sides :

1 recipe requires = 5/3 cups of sugar

1(1/2) recipe requires = (5/3) x 1(1/2) cups of sugar

3/2 recipe requires = (5/3) x (3/2) cups of sugar

3/2 recipe requires = 5/2 cups of sugar or 2.5  cups of sugar.

Therefore, Mrs. Marina requires 5/2 or 2.5 cups of sugar to make  one and one half of the recipe.

Answer:

-5x + 11

Step-by-step explanation:

All you're doing is substituting.

f(x)=-2x+3

f(1-x) = 2(1-x)+3

= 2 - 2x +3

= -2x + 5

g(x)=3x+3

g(1-x) = 3(1-x)+3

= 3 - 3x + 3

= -3x + 6

Now add them together and combine like terms:

f(1-x) + g(1-x)

-2x + 5 + -3x + 6

= -5x + 11

Answer:

  marked price = Rs. 3900

Step-by-step explanation:

The difference between the discounts is 30% -20% = 10% of the marked price. The difference in Rs is 120 -(-270) = 390. If Rs. 390 is 10% of the marked price, then the marked price is (Rs. 390)/(0.10) = Rs. 3900.

The marked price is Rs. 3900.

_____

Check

A 20% discount from 3900 is a price of 3120. If the profit is 120, the cost price is 3000. A 30% discount from 3900 is 2730. This is 270 below the 3000 cost price, so our answer is consistent with problem requirements.

Answer:

Independent Variable: Number of bagels bought

Dependent Variable: Total cost because it depends on the number of bagels bought.

Function: N(x)=1.75x

So, if x is the number of bagels bought, N(14) means that 14 bagels were bought. So you multiply 14 by the price; 1.75. So, N(x)=1.75*14 = $24.5

Step-by-step explanation:

Answer:

The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.

A function relating these variables is V(x) =1.75x.

So V(14) = 24.5, meaning 14 bagels will cost 24.5 dollars.

Answer:

350 girls

Step-by-step explanation:

So,

The secret to solving problems with ratios is to find the value of one unit.

5:7 = 12 units total

To find one unit, divide the total number of students by the total number of units.

600/12 = a

Simplify

50/1 = a

50 = a

The value of each unit is 50.

Now, multiply the units by the numbers in the ratio.

50(5) = b

250 = boys

50(7) = x

350 = x

There are 350 girls.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

(8 + 9) + 3 = 17 + 3 = 20

8 + (9 + 3) = 8 + 12 = 20

This is the property of associative.

The least number of cabins needed for campers is 8.

Given that, Shady Rivers summer camp has 188 campers this week.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

The least number of cabins needed = Total number of campers/Number of campers to each cabin

= 188/22

= 8.54

Therefore, the least number of cabins needed for campers is 8.

Answer:

0.28 pounds in each bag.

Step-by-step explanation:

There are 0.28 pounds in each snack-size bag.

In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings.

For example 4/2 = 2

We have been given that she bought 8.4 pounds of almonds. She divided them into 30 snack-size bags.

We have to determine the number of pounds in each bag.

The number of pounds in each bag = total quantity of almonds ÷ number of bags

The number of pounds in each bag = 8.4 pounds ÷ 30 bags

The number of pounds in each bag = 8.4/30

Apply the division operation, and we get

The number of pounds in each bag = 0.28 pounds

Thus, there are 0.28 pounds in each snack-size bag.

Answer: in each group, there are 8 students.

Step-by-step explanation:

We have a total of 26 students.

If we separate them into 3 equal groups (suppose that each group has X students) and leave 2 students left, we will have the relation:

3*X + 2 = 26

This means that 3 times the number of students in each group, plus the two students leftover must be equal to the initial number of students.

Now we can solve this for X.

3*X + 2 = 26

3*X = 26 - 2 = 24

X = 24/3 = 8

X = 8

This means that in each group there are 8 students.

The first graph shows the x-intercept of -3 and y - intercept of 5.

Option A is true.

What is Intercepts?

The points in which the graph crosses the two axis ( x and y axis) are called Intercepts.

Given that;

The x - intercepts = -3

And, The y - intercepts = 5

Since,

The x - intercepts = -3

That's mean the line cross at the point - 3 on x - axis.

And, The y - intercepts = 5

That's mean the line cross at the point 5 on y - axis.

Clearly, In graph first;

The graph of the line is crosses at the point on x - axis at the point -3 and y - axis at the point 5.

Step-by-step explanation:

[tex]a_n[/tex] is the n-th term in the sequence. So

• the first term (n = 1) is a₁ = 3 + 6•(1 - 1) = 3

• the second term (n = 2) is a₂ = 3 + 6•(2 - 1) = 9

• the third term (n = 3) is a₃ = 3 + 6•(3 - 1) = 15

• the fourth term (n = 4) is a₄ = 3 + 6•(4 - 1) = 21

• the fifth term (n = 5) is a₅ = 3 + 6•(5 - 1) = 27

The common difference between terms is what you get from subtracting consecutive terms in the sequence, or the number [tex]a_n-a_{n-1}[/tex]. Just by taking any two consecutive numbers from above, you have d = 6, since

9 - 3 = 6

15 - 9 = 6

and so on. More generally,

[tex]a_n-a_{n-1}=(3+6\cdot(n-1)) - (3+6\cdot(n-2))=6\cdot((n-1)-(n-2))=6[/tex]
