The value of the variables are x is 5. and AB is 10

Given, the sides of the rectangle are:

length = 2x ₊ 2 and

breadth = 3x ₋ 2

perimeter of the rectangle = 48 units

2(l ₊ b) = 48

2(3x ₋ 2 ₊ 2x ₊ 1) = 48

2(5x ₋ 1) = 48

10x ₋ 2 = 48

10x = 48 ₊ 2

10x = 50

x = 50/10

x = 5

therefore, length = 2x ₊ 1 = 2(5) ₊ 1 = 11 and

breadth = 3x ₋ 2 = 3(5) ₋ 5 = 10

hence we get the value of x as 5

The value of the numbers x and y is a 3 and 25.

According to the statement

We have to find that the value of the numbers.

So, For this purpose, we know that the

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.

From the given information:

One number is seven more than six times another number. If the sum of the numbers is 28.

Then

Let The first number = y

The second number = x

Hence, y = (7 + 6x)

Their sum is therefore;

x + 7 + 6x = 28

7x = 21

x = 3

Hence, the second number is a; 7 + 6x = 7 + 6(3);

y = 25.

So, The value of the numbers x and y is a 3 and 25.

The time takes Ben to walk to the library is 80 minutes.

Given that, Ben can walk to the library 4 miles away, but it takes him 20 minutes longer than it would walk to school 3 miles away.

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. The proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Let the time taken Ben to walk to the school be x, so the time taken to walk to the library be x+20.

Now, 4 : x+20 :: 3 : x

⇒4x=3(x+20)

⇒4x=3x+60

⇒x=60

The number of cups of chocolate chips she should use is 3 cups.

Consider a cookie recipe in which 1½ cups of chocolate chips are needed to make 25 cookies.

She decided to double the number of cookies.

Therefore,

Remember she wants to double the size of cookies,

25 cookies =  1½ cups of chocolate chips

2(25 cookies) = ?

cross multiply

number of cups of chocolate chips required = 50 × 1.5 / 25

number of cups of chocolate chips required = 75 / 25

number of cups of chocolate chips required = 3 cups

Therefore, the number of cups of chocolate chips she should use is 3 cups.

The Line t || Line v the  value of angle m∠5  is 69.28° .

A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.

Given:

Line t || Line v

m∠5 =5x + 45

m∠7 = 12x - 11,

According to given question we have

Line t || Line v

Using the property of interior angles on same sides we get

m∠5 =m∠7

5x + 45=12x - 11

compare like terms we get

45-11=12x-5x

34=7x

x=34/7°

By put the value of x

m∠5 =5x + 45

m∠5 =5*34/7+45

m∠5 =485/7=69.28°

m∠7 =12x - 11=12*34/7-11

Step-by-step explanation:

The difference between depths in January and July is 14 feets

The depth of a local river averages 16 ft., which is represented as |−16|.

In January,  The depth of a local river measured 4 ft. deep, or |−4|

in July, The depth of a local river  18 ft., or |−18|

The average depth of a local river  is measured as -16 because it is below the ground level and hence measured or plotted on -y axis

the difference between depths in January and July can be measured as

|−18| -  |−4|

This is absolute sign which means every number inside this sign should be treated as positive

18 - 4 = 14

Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.

The cm the volcano wears down each year = 20 cm / 5 = 4cm

10 / 2 = 5cm

Given that;

The expression is,

x/7 = 3x + 20/ 35

Now, We can solve as;

x/7 = 3x + 20/ 35

Multiply 35 in both side,

35 × x/7 = 35 × (3x + 20)/35

5x = 3x + 20

Subtract 3x both side,

5x - 3x = 3x + 20 - 3x

P'(x, y) = (1, - 4)

P''(x, y) = (1, - 4) + (- 2, 0)

we get that the rental cost for each movie is $ 4.5 and each video game is $ 5.5.

Let the cost of number of movies be x and the cost of number of video games be y.

So, the equations are:

5 x + 3 y = 39

2 x + 12 y = 75

2 x = 75 - 12 y

x = 75/2 - 6 y

Put it in the first one, we get that:

5 ( 75/2 - 6y) + 3y = 39

375/2 - 30 y + 3 y = 39

27 y = 187.5 - 39

27 y = 148.5

y = 148.5 / 27

y = $ 5.5

x = 75/2 - 6 y

x = 37.5 - 6 (5.5)

x = 37.5 - 33
