Solve for x. 0.9(5x+4) = 5.7 2.5X

Alenkinab [10]

Answer:

x=0.369231

Step-by-step explanation:

0.9(5x+4)=5.7(2.5x)

Step 1: Simplify both sides of the equation.

0.9(5x+4)=5.7(2.5x)

(0.9)(5x)+(0.9)(4)=5.7(2.5x)(Distribute)

4.5x+3.6=14.25x

Step 2: Subtract 14.25x from both sides.

4.5x+3.6−14.25x=14.25x−14.25x

−9.75x+3.6=0

Step 3: Subtract 3.6 from both sides.

−9.75x+3.6−3.6=0−3.6

−9.75x=−3.6

Step 4: Divide both sides by -9.75.

−9.75x/ −9.75 = −3.6/ −9.75

x=0.369231

disa [49]

$x=0.5777...\ \ \ |multiply\ both\ sides\ by\ 10\\\\10x=5.777...\ \ \ \ |multiply\ both\ sides\ by\ 10\\\\100x=57.777...\\\\make\ a\ difference\ 100x-10x:\\\\90x=57.777...-5.777...\\\\90x=52\ \ \ \ |divide\ both\ sides\ by\ 90\\\\x=\frac{52}{90}\\\\x=\frac{26}{45}\\\\\boxed{0.5777...=\frac{26}{45}}$

On a coordinate plane, a graph of a floor function has horizontal segments that are each 1 unit long. The left end of each segme

UNO [17]

Answer: Over the interval x = 2≤ x <3, y = 2.

For an input value of –1.5, the corresponding output value is -2

Step-by-step explanation: Easier to find the information of you make a sketch of the graph described. (Good description!)

To find the value, look at the graphed segments that correspond to the given values.

X represents input values, Y represents output values.
