Solve: 9x-18=3(3x-2)-12​
Angelina_Jolie [31]

Answer:

<h2>Solution: any number (x ∈ R)</h2>

Step-by-step explanation:

9x-18=3(3x-2)-12\qquad\text{use the distributive property}\\\\9x-18=(3)(3x)+(3)(-2)-12\\\\9x-18=9x-6-12\qquad\text{subtract}\ 9x\ \text{from both sides}\\\\9x-9x-18=9x-9x-18\\\\-18=-18\qquad\bold{TRUE}

We received a true equation without the variable x.

Conclusion:

The equation is identity. Each number satisfies this equation.

The product of 2 numbers is +15 and their difference is -8. What are the 2 numbers?​
Eddi Din [679]

Answer:

if the number are x and y

then

xy=15. *1

x-y=-8. *2

x=y-8. *3

by *1&3

y(y-8)=15

{y}^{2}  - 8y = 15 \\  {y}^{2} - 8y - 15 = 0 \\ by \: quadratic \: equation \: formula \: it \: becomes \: 9.6or - 1.56

x-y=-8

x=-9.56or. x=1.56

<em><u>if y =-1.56 x equals -9.56and if </u></em>

<em><u>if y =-1.56 x equals -9.56and if if y=9.56. x equals 1.56</u></em>

32/4 times (16 times 1 over 2) minus 2 show your work I NEED HELP ASAP PLSSSS MY DAD IS GOING TO KILL ME
Gnom [1K]

Answer:

62

Step-by-step explanation:

In this scenario, we would use BODMAS to determine where to start.

B - Brackets

O- Of

D - Division

M - Multiplication

A - Addition

S - Subtraction

First, let's start with the brackets.

16 X \frac{1}{2} is the same as 16 X 0.5.

16 X \frac{1}{2} = 8

Next is the division sum.

32 ÷ 4 = 8

Afterwards, we multiply both answers.

8 X 8 = 64

Your answer is then minused by 2 and leads to the final answer.

64 - 2 = 62
