Answer: x = 651.5

Step-by-step explanation:

First, we can re-write the equation as = 2x - 7.

Now, we simplify 6^4 = 1296.

1296 = 2x - 7

1303 = 2x

x = 651.5

Solve for c<br><br><br> R=5(c/a-0.3)

aalyn [17]

we have

$R=5(c/a-0.3)$

Solve for c--------> that means that clear variable c

so

Divide by $5$ both sides

$R/5=(c/a-0.3)$

Adds $0.3$ both sides

$(R/5)+0.3=(c/a)$

Multiply by $a$ both sides

$a[(R/5)+0.3]=c$

so

$c=a[(R/5)+0.3]$

therefore

<u>the answer is</u>

$c=a[(R/5)+0.3]$

Which of the following is equivalent to 2x+3y=6

valentina_108 [34]

Answer:

A. y = -2/3x + 2

Step-by-step explanation:

Your is to isolate the y. The first thing you would do is subtract the 2x,

2x + 3y = 6

-2x =

3y = -2x +6

then to isolate the ,y, you would next divide everything by 3, so that the ,y, stays by itself.

3y/3 = -2x/3 +6/3

Simplify,

y = -2/3x + 2

4 x plus 8 y equals 40, when y equals 0.8?

Over [174]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{x = 8.4}}}}}$

Step-by-step explanation:

Given, y = 0.8

To find : value of x

$\sf{4x + 8y = 40}$

plug the value of y

$\longrightarrow{ \sf{4x + 8 \times 0.8 = 40}}$

Multiply the numbers: 8 and 0.8

$\longrightarrow{ \sf{4x + 6.4 = 40}}$

Move 6.4 to right hand side and change it's sign

$\longrightarrow{ \sf{4x = 40 - 6.4}}$

Subtract 6.4 from 40

$\longrightarrow{ \sf{4x = 33.6}}$

Divide both sides by 4

$\longrightarrow{ \sf{ \frac{4x}{4} = \frac{33.6}{4} }}$

Calculate

$\longrightarrow{ \sf{x = 8.4}}$

Hope I helped!

Best regards ! :D
