Simplifying

2x + -7 = 3x + 5

Reorder the terms:

-7 + 2x = 3x + 5

Reorder the terms:

-7 + 2x = 5 + 3x

Solving

-7 + 2x = 5 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-7 + 2x + -3x = 5 + 3x + -3x

Combine like terms: 2x + -3x = -1x

-7 + -1x = 5 + 3x + -3x

Combine like terms: 3x + -3x = 0

-7 + -1x = 5 + 0

-7 + -1x = 5

Add '7' to each side of the equation.

-7 + 7 + -1x = 5 + 7

Combine like terms: -7 + 7 = 0

0 + -1x = 5 + 7

-1x = 5 + 7

Combine like terms: 5 + 7 = 12

-1x = 12

Divide each side by '-1'.

x = -12

Simplifying

x = -12

Answer:

w will be less than 75.

Step-by-step explanation:

Given the expression;

75/w = 150/100

We are to determine whether w is greater than or less than 75.

If you look at the right hand side of the expression, 150/100, you will see that the denominator is greater than the numerator. Due to the equality sign between the fractions, the same will be applicable to 75/w meaning that w will also be less than 75.

A) The first term of the AP is; 9

B) The common difference of the AP is; 4

C) The sum of the first 15 terms of the AP is; 555

Formula for nth term of an AP is;

a_n = a + (n - 1)d

Where;

a is first term

n is number of terms

d is common difference between consecutive terms

We are told the 10th term is 45

Thus;

45 = a + (10 - 1)d

a + 9d = 45 - - - (1)

Formula for sum of n terms of an AP is;

S_n = (n/2)(2a + (n - 1)d)

Sum of first 10 terms is 270. Thus;

270 = (10/2)(2a + (10 - 1)d)

5(2a + 9d) = 270

2a + 9d = 270/5

2a + 9d = 54 - - - (2)

Solving both equations simultaneously gives;

a = 9 and d = 4

Thus;

First term = 9

Difference = 4

Sum of first 15 terms is;

S_15 = (15/2)(2(9) + (15 - 1)4)

S_15 = 7.5(18 + 56)

S_15 = 555

Answer:

Number of movies for equal wage = 20

Step-by-step explanation:

Assume;

Number of movies for equal wage = x

So,

75 + 2x = 5.75 x

3.75 x = 75

x = 75 / 3.75

x = 20

So,

Number of movies for equal wage = 20

4 and 10 - acute

2 is acute, but 3 is obtuse

8 and 12 - acute

6 and 12 - acute

1 is obtuse 2 is acute

15 and 11 are obtuse

9 is obtuse but 8 is acute

2 and 4 are acute.

Step-by-step explanation:

I believe this is correct.

A right angle is a perfect corner. Think of a square and look at the corner, it doesn't go farther or shorter when it hits a side if you know what I mean by that. An acute angle is shorter than a right angle, or stops before it can be called a right angle. An obtuse angle is bigger than a right angle, or ends after the right angle point. I hope what I have just said here helps you with future problems!! Good luck :))

The number when divided by 43 has a quotient of 3 with 28 as a remainder is 157

The number is 157

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be = A

Now , the equation will be

A number divided by 43 has a quotient of 3 with 28 as a remainder

So , A / 43 = 3 + 28/43   be equation (1)

On simplifying the equation , we get

A / 43 = 3 + 28 / 43

A/43 = ( 3 x 43 + 28 ) / 43

Multiply by 43 on both sides of the equation , we get

A = 3 x 43 + 28

A = 129 + 28

A = 157

Therefore , the value of A is 157

Hence , The number when divided by 43 has a quotient of 3 with 28 as a remainder is 157

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Width of room = 4 cm

Length of room = 12 cm

And, The scale model uses a scale in which 2 centimeters represents 1.4 meters.

Now,

Since, The scale model uses a scale in which 2 centimeters represents 1.4 meters.

That is,

2 cm = 1.4 m

1 cm = 0.7 m

So, The width of room = 4 cm

                                   = 4 x 0.7 m

                                   = 2.8 m

And, The length of room = 12 cm

                                      = 12 x 0.7 m

                                      = 8.4 m

Thus, The actual area of room = Length x Width

                                               = 8.4 x 2.8 m²

                                              = 23.52 m²

Therefore, The actual area of the room will be 23.52 m².
