Answer:

Step-by-step explanation:

y=9x-1

8x-4y=92

substitute y=9x-1

8x-4(9x-1)=92

8x-36x+4=92

-28x+4=92

-28x=92-4=88

x=88/-28=22/-7 = -3.14

y = 9(-3.14) -1 = -28.26-1 = -29.26

What is the value of A when we rewrite 2^x-6 + 2x as A * 2^x?

Leto [7]

Algebraic expressions are expressions that use numbers and variables

The value of A is 65/64

<h3>How to determine the value of A</h3>

The expression is given as:

$2^{x - 6} + 2^x$

Rewrite the expression as:

$2^{x - 6} + 2^x = \frac{2^x}{2^6} + 2^x$

Factor out 2^x

$2^{x - 6} + 2^x = 2^x(\frac{1}{2^6} + 1)$

Rewrite as product

$2^{x - 6} + 2^x = 2^x * (\frac{1}{2^6} + 1)$

The expression to compare with is given as: A * 2^x.

So, we have:

$A * 2^x =2^x * (\frac{1}{2^6} + 1)$

Divide both sides by 2^x

$A =\frac{1}{2^6} + 1$

Take LCM

$A =\frac{1 + 2^6}{2^6}$

$A =\frac{65}{64}$

Hence, the value of A is 65/64

Given that ABCD is a rhombus, what is the value of x?

SashulF [63]

Answer:

Step-by-step explanation:

A rhombus is divided into four congruent triangles. The two given angles are complementary, meaning they add up to 90 degrees. Set up an equation:

$(4x-25)+x=90$

$4x-25+x=90$ Take out the parentheses

$5x-25=90$ Combine like terms

$5x=115$ Add 25 to both sides so as to isolate the variable

$x=23$ Divide both sides by 5

A bag contains blue marbles and red marbles, 56 in total. The number of blue marbles is 8 more than 2 times the number of red ma

Nikolay [14]

24 Blue marbles.

Explanation:

56 - 8 = 48

48 / 2 = 24

so if there are 24 blue marbles, 24 x 2 = 48, and then 8 more is 56.
