What is24/3 as a mixed number

Expression A: 3(x + 2) Expression B: 3x + 6....... Which statement does not show that these expressions are equivalent? O A. Sub

Dovator [93]

Answer:

D. 3(x+2) can be rewritten as 3x + 6 using the distributive property

Step-by-step explanation:

Given

$3(x + 2) = 3x + 6$

Required

Explain

From the list of given options, option D answers the question.

This is because, the expression above involves distributive property and only option D correctly states that.

A distributive property is:

$a*(b + c) = a*b + a * c$

In this case:

$a = 3$ $b = x$ and $c = 2$

So:

$a*(b + c) = a*b + a * c$

Substitute values for a, b and c

$3*(x + 2) = 3 * x + 3 * 2$

$3(x + 2) = 3x + 6$

[HELP PLEASE ALGEBRA] Would the answer only be B?

Salsk061 [2.6K]

Hello,

|x+4|=3x-5
if x+4>=0 then
 |x+4|=x+4
 x+4=3x-5
 2x=9
 x=9/2
else
 x+4<0 : x<-4
 |x+4|=-(x+4)
 -(x+4)=3x-5
 -x-4=3x-5
 4x=1
 x=1/4 : to exclude since x<-4
end if

Only one solution : x=9/2

what is (5.91 x 10^-3) - (8.7 x 10^10) written in a scientific notation? Please answer asap thank you :))

nata0808 [166]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the expression

$\left(5.91\times \:10^{-3}\right)-\left(8.7\times \:10^{10}\right)$

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a$

$=5.91\times \:10^{-3}-8.7\times \:10^{10}$

as

$5.91\times \:10^{-3}$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}$

$=5.91\times \frac{1}{10^3}$

$=\frac{5.91}{1000}$

$=0.00591$

similarly

$8.7\times \:10^{10}$

Convert element to a decimal form

$10^{10}=10000000000$

so

$=10000000000\times \:8.7$

$\mathrm{Multiply\:the\:numbers:}\:8.7\times \:10000000000=87000000000$

$=87000000000$

Thus, the expression becomes

$\left(5.91\times \:\:10^{-3}\right)-\left(8.7\times \:\:10^{10}\right)=5.91\times \:\:10^{-3}-8.7\times \:\:10^{10}$

$=0.00591-87000000000$

$=-86999999999.9941$

Hence,

converting -86999999999.9941 in a scientific notation

In order to make our job easier we will remove the sign "-" from number -86999999999.9941 (we will write "-" at the final solution). So after this step we have:

−86999999999.9941 ⟶ 86999999999.9941

In order to write number 86999999999.9941 in scientific notation, we need to move the decimal point from its current location (black dot) to the new position such as:

8.6999999999.9941

So, we need to move the decimal point 10 places to the right.

This means that the power of 10 will be positive 10.

Now we have that the

Number part = 8.69999999999941 and

Exponent part = 10

Thus, we conclude that:

−86999999999.9941 = − 8.69999999999941 × 10¹⁰

Matt had instructions to take a box of nails to a classroom that has a number equal to the remainder of the division 2960÷9. mat

mars1129 [50]

2960 mod 9 = 8. So the classrooms he can take it to are 8, 17, 26, ... 17 is among these so he is correct
