Answer:

the answer is D

Step-by-step explanation:

Select the correct answer. Which statement is true about this equation? -9(x + 3) + 12 = -3(2x + 5) − 3x A. The equation has one solution, x = 1. B. The equation has one solution, x = 0. C. The equation has no solution. D. The equation has infinitely many solutions.

Answers

Answer:

its D

Step-by-step explanation:

-9(x + 3) + 12 = -3(2x + 5) − 3x

-9x-27+25 = -6x-15-3x

-9x-15 = -9x - 15

same on both sides

so x has infinitely many solutions

The equation has no solutions. Option C is correct.

To figure out which statement is true for equation -9(x + 3) + 12 = -3(2x + 5) − 3x.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
-9(x + 3) + 12 = -3(2x + 5) − 3x.
Simplification,
LHS
= -9(x + 3) + 12

= -9x -21 + 12
= -9x -9

RHS,
=  -3(2x + 5) − 3x
= -6x - 15 - 3x
= -9x - 15
Equation RHS and LHS,
-9x - 15 = -9x -9
-15 = -9
Implies, the value of x terminate means the given expression has no solution,

Thus, the equation has no solutions. Option C is correct.

If 2x + 3 = 13, then x = 5.​

Answers

Answer:

Given that x=5, when we substitute in 5 for 2x + 3 = 13, the equation will turn out to be true.

Step-by-step explanation:

2x + 3 = 13       x=5

2(5)+3=13

10+3=13

13=13

2x + 3 = 13

x=5

2(5)+3=13

10+3=13

13=13

Answers

Answer:

A Δ DOC = 6 in²

Step-by-step explanation:

Look at the attached graph

∵ ABCD is a trapezoid with legs AB and CD

∴ AD // BC

In Δs ABC and DCB

∵ BC is a common base

→ The heights of the Δs drawn from the points A and D to the base

   BC are equal because the line joining A and D, AD is parallel to

   the base BC

∴ Their heights are equal

→ Triangles of the same base and equal heights are equal in areas

∴ A Δ ABC = A Δ DCB

∵ A Δ ABC = A Δ ABO + A Δ BOC

∵ A Δ DCB = A Δ DOC + A Δ COB

→ Equate their right sides

∴ A Δ ABO + A Δ BOC = A Δ DOC + A Δ COB

∵ A Δ BOC = A Δ COB ⇒ common triangle

∴ A Δ ABO = A Δ DOC

∵ A Δ ABO = 6 in²

∴ A Δ DOC = 6 in²

Jack can long-jump 195% of his height with a running start. If Jack is 50 inches tall, how far can he long-jump?

Answers

Answer: 97.5 in

1.95 x 50 = 97.5

Jack can jump upto 97.5 inches.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Jack who can long-jump 195% of his height with a running start.

Assume that he can jump a height of [x] inches. So -

x = 195% of 50

x = (195/100) x 50

x = 97.5 inches

Therefore, Jack can jump upto 97.5 inches.

The balance of a loan is $2,570 in January, and the monthly payment is $125.50. The relationship between the loan balance, y, and the number of monthly payments made since January, x, can be represented by the equation y = 2,570 - 125.50x. In what months does the loan balance, y, meet the condition, $1,600 < y < $2,000? January February March April May June July August September October November December

Answers

Answer:

600<2570-125.5x<2000  subtract 2570 from all terms...

-970<-125.5x<-570  divide all terms by -125.5 (and reverse signs because of division by a negative!)

7.73>x>4.54  and x is months since January, and since months can only be integers...

x=[5,7]

So January + 5, 6, and 7 respectively are the three months that satisfy the equation...

June, July, and August.

4b ≥ -10

4/4     -10/4

b ≥ -2.5

Answer:

 b ≥ [tex]-\frac{5}{2}[/tex]

Step-by-step explanation:

The expression:

      5b  - b  - 1 ≥ -11

Now to solve this problem, we must be aware of some rules of inequality.

When dividing or multiplying with a negative value, the sign of the inequality must change;

         5b  - b  - 1 ≥ -11

             4b  - 1 ≥ -11

  Add + 1 to both sides;

            4b -1 + 1 ≥ -11 + 1

            4b ≥ -10

Now divided both sides by 4;

            [tex]\frac{4b}{4}[/tex] ≥ [tex]\frac{-10}{4}[/tex]  

           b ≥ [tex]-\frac{5}{2}[/tex]

CD and EF are parrellel to AB.They divide the area of triangle PAB into three equal parts. If PE=1, what is AC?

Answers

Answer:

AC is approximately 0.3178

Step-by-step explanation:

The given parameters are;

In ΔPAB

CD ║ EF ║ AB

The area of triangle ΔPEF = 1/3 × area of triangle ΔPAB

Therefore, PE = 1/√3·PA

PA = √3

We have area of ΔPCD = 2/3 × area of triangle ΔPAB

∴ PC = √(2/3) × PA = √(2/3) × √3

PC = √2

Therefore, AC = PA - PC = √3 - √2

AC = √3 - √2 ≈ 0.3178

6. If m∠COD=8x+13, m∠BOC=3x-10, and m∠BOD=12x-6, find m∠BOD

Answers

Answer:

Step-by-step explanation:

Given

m∠COD=8x+13,

m∠BOC=3x-10, and

m∠BOD=12x-6

The following addition property is true;

<BOD = <BOC + <COD

Substitute

12x-6 = 3x-10+8x+13

12x-6 = 11x+3

12x-11x = 3+6

x = 9

Get <BOD

<BOD = 12x-6

<BOD = 12(9)-6

<BOD = 108-6
