Total brain fart! 24+5x=-x+6(5a-4)

kow [346]

Answer:

When solving for x, answer = $\large\boxed{x = 5a - 8}$

When solving for a, answer = $\large\boxed{a = 1/5x + 8/5}$

Step-by-step explanation:

24 + 5x = -x + 6(5a - 4)

Start by multiplying 6 by the values in the parenthesis

24 + 5x = -x + 30a - 24

Add 24 to both sides of the equation

48 + 5x = -x + 30a

Add 1x to both sides of the equation

48 + 6x = 30a

Subtract 48 from both sides of the equation

6x = 30a - 48

Divide both sides of the equation by 6

x = 5a - 8 (Answer when solving for x)

Add 8 to both sides of the equation

x + 8 = 5a

Divide both sides of the equation by 5

a = 1/5x + 8/5 (Answer when solving for a)

-----------------------------------------

When solving for x, answer = $\large\boxed{x = 5a - 8}$

When solving for a, answer = $\large\boxed{a = 1/5x + 8/5}$

Hope this helps :)

A dieter believes that the average number of calories in a homemade peanut better cookie is more than the average number of calo

zalisa [80]

The confidence interval formula is computed by:

Xbar ± Z s/ sqrt (n)

Where:

Xbar is the mean

Z is the z value

S is the standard deviation

N is the number of samples

So our given are:

90% confidence interval with a z value of 1.645

Sample size 40, 45

Mean 180, 179

Standard deviation 2, 4

So plugging that information in the data will give us a confidence interval:

For 1:

Xbar ± Z s/ sqrt (n)

= 180 ± 1.645 (2 / sqrt (40))

= 180 ± 1.645 (0.316227766)

= 180 ± 0.520194675

= 179.48, 180.52

For 2:

Xbar ± Z s/ sqrt (n)

= 179 ± 1.645 (4 / sqrt (45))

= 179 ± 1.645 (0.596284794)

therefore, the answer is letter b

Find x a) 21 √2 b)7 c)21 √2/2 d)21 √3/2

fgiga [73]

Answer:

Step-by-step explanation:

Use the sine ratio in the left, right triangle to find the common side to both triangles and the exact values

sin60° = $\frac{\sqrt{3} }{2}$ , cos45° = $\frac{1}{\sqrt{2} }$ , thus

sin60° = $\frac{opposite}{hypotenuse}$ = $\frac{opp}{7\sqrt{3} }$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2 × opp = 21 ( divide both sides by 2 )

opp = $\frac{21}{2}$

Now consider the right triangle on the right, using the cosine ratio

cos45° = $\frac{adjacent}{hypotenuse}$ = $\frac{\frac{21}{2} }{x}$ = $\frac{1}{\sqrt{2} }$ ( cross- multiply )

x = $\frac{21}{2}$ × $\sqrt{2}$ = $\frac{21\sqrt{2} }{2}$ → C

If (x+3)divided by 3 = 9 what is x

defon

Answer:

x = 24

Step-by-step explanation:

Given that:

(x+3)/3 = 9

multiplying both sides by 3

(x+3) = 9*3

(x+3)= 27

Subtracting 3 from both sides

x= 27-3

x=24

I hope it will help you!
