Answer:

x = 3

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

7x + 2 = 4x + 11

Step 2: Solve for x

Subtract 4x on both sides:                    3x + 2 = 11Subtract 2 on both sides:                      3x = 9Divide 3 on both sides:                          x = 3

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    7(3) + 2 = 4(3) + 11Multiply:                               21 + 2 = 12 + 11Add:                                     23 = 23

Here we see that 23 does indeed equal 23.

∴ x = 3 is the solution to the equation.

Solve for m: -8 = m/-10 - 16

Answers

Answer:

m = -80

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

-8 = m/-10 - 16

Step 2: Solve for m

Add 16 to both sides:                    8 = m/-10Multiply -10 on both sides:            -80 = mRewrite:                                          m = -80

Answer:

We have this equation:

-8 = m/-10 -1

We can add 8 at both sides:

-8 + 8 = m/-10 -16 + 8

0 = m/-10 -8

Now, we can multiply -8 by -10 with the objective of having the same denominator (-10) in all numbers:

0 = m/-10 - 8*(-10)/-10

0 = m/-10 +80/-10

Now, we can delete all denominators

0 = m + 80

And we can say m = -80

Now, we can replace it to see if it's true:

-80/-10 - 16 = -8, so we know that's true

-80/-10 -16 = 8 - 16 = -8 ..

after a 30% reduction, you purchase a dictionary for $30.80 what was the dictionary price before the reduction

Answers

Answer:

Well the original price would be $44

Step-by-step explanation:

So make an equation

Lets make X stand for the price before the deduction

so x-x(0.3)=30.80

Subtracting the X by x(0.3) would tell us the price, the 0.3 stands for 30 percent and we know its 30 percent of X so we subtract that since 0.3x would give the change

Now just solve the equation

You’ll get 44.

If t= 9m,what is the area of the triangle

Help

Answers

Answer: the answer

we use the formula 1/2 .b .h

Step-by-step explanation:

the answer is 1,134, we substitute the t to 9 for each number, for example 4(9) 7(9)

4(9)= 36

7(9)=63

now we find the half of our bottom number which is 4=36

1/2 36= 18

so now we have 18x63=1,134

so our answer is 1,134

The area of the triangle is 1134 m²

What is the area of Triangle?

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

Given data ,

The value of t = 9 m

Let the base of the triangle be b = 4t

                                                       = 4 x 9

                                                       = 36 m

Let the height of the triangle be h = 7t

                                                         = 7 x 9

                                                         = 63 m

Now , the area of the triangle = ( 1/2 ) x Length x Base

So , substituting the values , we get

Area of the Triangle = ( 1/2 ) x 36 x 63

                                 = 18 x 63 m²

                                 = 1134 m²

Therefore , the area is 1134 m²

Hence , the area of the triangle is 1134 m²

2.3y+3.2-y=2.1+1.3y+1.1
2/3x+2/3+1/5x=2/3x
20+4r=32-2r

Answers

Answer:

2.3y+3.2-y=2.1+1.3y+1.1

Step-by-step explanation:

The first equation has one solution: z = 0.25.

The second equation has infinitely many solutions.

The third equation has one solution: x = -10/3.

The fourth equation has one solution: r = 2.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

(a) 2.2z+3z=4.5-3.2

Simplifying the left-hand side, we get: 5.2z = 1.3

z = 1.3/5.2 = 0.25

Therefore, the equation has one solution: z = 0.25.

(b)2.3y+3.2-y=2.1+1.3y+1.1

1.3y + 3.2 = 2.2 + 1.3y

Therefore, the equation has infinitely many solutions.

(c) 2/3x+2/3+1/5x=2/3x

Simplifying the left-hand side, we get: 1/5x + 2/3 = 0

1/5x = -2/3

x = -10/3.

(d) 20+4r=32-2r

6r = 12

r = 2

Therefore, the equation has one solution: r = 2.

Hence, The first equation has one solution: z = 0.25.

The second equation has infinitely many solutions.

The third equation has one solution: x = -10/3.

The fourth equation has one solution: r = 2.

Step-by-step explanation:

If baseball team scored 5 more runs in its second game than its first. The team scored twice as many runs as the first game in the third game. The total number of runs in all three games was 29.Then 11 runs were scored in the second game

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Let the runs scored by team in first game be x.

The team scored 5 more runs in its second game than its first.

x+5

The team scored twice as many runs as the first game in the third game.

2x

The total number of runs in all three games was 29

This we can write as x+x+5+2x=29

Add x variable terms

4x+5=29

Subtract 5 on both sides

4x=24

x=6

So the score in the second game will be x+5=6+5=11

Hence, 11 runs were scored in the second game

To find where this line reaches the y axis, you simply need to assign the value 0 to x, and solve for y:
