2/5=x/65 solve for x
A: x=1/26
B: x=16
C: x=28
D: x=26
please help me

Answers

Answer 1

Answer:

Solve  :    -x+26 = 0 

 Subtract  26  from both sides of the equation : 

                      -x = -26 

Multiply both sides of the equation by (-1) :  x = 26 

Answer 2

[tex] \frac{2}{5} = \frac{x}{65} [/tex]

[tex]2 \times 65 = 5 \times x[/tex]

[tex]130 = 5x[/tex]

[tex]x = \frac{130}{5} [/tex]

[tex] \color{hotpink}x = 26[/tex]

Therefore , the correct option is :-

[tex]\color{plum}D) \: x = 26[/tex]

Answer:

the answer is 7(13a+4c)

ind the GCF of 91 and 28 since a and c are separate variables. this is 7; since 91/7 is 13 and 28/7 is 4. we can take this out of the parentheses like this:

7(13a+4c)

Answer:

7(13a+4c)

Step-by-step explanation:

hi! let's find the GCF of 91 and 28 since a and c are separate variables. this is 7, since 91/7 is 13 and 28/7 is 4. we can take this out of the parentheses like this:

7(13a+4c)

this is basically like reverse distribution. if you distribute the 7 into the parentheses, you will get the original unfactored expression.

Which of the following rules could represent the function shown in the table?
f(x) = -2x
f(x) = 2x-1
f(x) = 2x+1

Answers

Answer: f(x) = 2x+1

Step-by-step explanation: Substitute the variable with the “x” values in the chart to check your answers.

1. f(x) = 2x+1

Add in the “x” value

f(x) = 2x(-1) or 2 multiplied by -1

f(x) = -2 + 1

If the answer is equal to your “y” value , it can represent the function.

Answer:

4

Step-by-step explanation:

First substitute all numbers into the equation:

= 4 ( 3 + ( -3 )( -2 ) ) - 2 ( 4 )^2

Then simply answer the question and evaluate:

= 4 ( 3 + ( 6 ) ) - 2 ( 16 )

= 4 ( 9 ) - 2 ( 16 )

= 36 - 2 ( 16 )

= 36 - 32
