Answer: Yes

Step-by-step explanation: To write the fraction 2/8 in lowest terms, we divide the numerator and the denominator by the greatest common factor of 2 and 8.

Since the factors of 2 are 1 and 2 and the factors of 8 are 1, 2, 4, and 8, the greatest common factor of 2 and 8 is 2.

This means that we divide the numerator and the denominator of 2/8 by 2 and we get the equivalent fraction 1/4.

This means that 2/8 can be reduced.

Consider the equation 0.75⋅10^w/3=30

Nastasia [14]

Answer:

The value of w is:

$w=3\cdot log_{10}(40)$

Step-by-step explanation:

We have to calculate w from the equation

$0.75\cdot 10^{w/3}=30$

The solution has to be expressed as a logarithm in base 10.

We can solve it like:

$0.75\cdot10^{w/3}=30\\\\10^{w/3}=30/0.75=40\\\\(w/3)log_{10}(10)=log_{10}(40)\\\\w/3=log_{10}(40)\\\\w=3\cdot log_{10}(40)$

The value of w is:

$w=3\cdot log_{10}(40)$

Solve the equation 3x-2 4 - 2x - 5- 1 + x 3 6

Nataly_w [17]

Answer:

$\boxed{\sf x=12}$

Step-by-step explanation:

$\sf \cfrac{3x-2}{4}-\cfrac{2x-5}{3}=\cfrac{1+x}{6}$

First, let's find the LCM of 4, 3, and 6.

How to find the LCM:

→ List multiples of each number.

→ Find the smallest number on each list.

4: 4, 8, 12, 16, 20, 24..

3: 3, 6, 9, 12, 15, 18, 21, 24, 27....

6: 6, 12, 18, 24, 30, 36, 42...

LCM: 12

_________

Now, we'll Multiply by LCM:

$\sf \cfrac{3x-2}{4}\times \:12-\cfrac{2x-5}{3}\times \:12=\cfrac{1+x}{6}\times \:12$

Simplify:

$\sf 3\left(3x-2\right)-4\left(2x-5\right)=2\left(x+1\right)$

Now, expand, Apply the Distributive property:

$\bold{ 3\left(3x-2\right)-4\left(2x-5\right)}$

$\sf 9x-6-8x+20$

Combine like terms:

$\sf x+14$

________

$\bold{ 2\left(x+1\right)}$

$\sf 2x+2$

$\sf x+14=2x+2$

Subtract 14 from both sides:

$\sf x+14-14=2x+2-14$

Simplify:

$\sf x=2x-12$

Subtract 2x from both sides:

$\sf x-2x=2x-12-2x$

Simplify:

$\sf -x=-12$

Divide both sides by -1:

$\sf \cfrac{-x}{-1}=\cfrac{-12}{-1}$

$\sf x=12$

Of 30 students 1/3 play sports 2/5 of them play soccer how many play soccer

vfiekz [6]

30 ÷ 3 = 10 = 1/3. So 10 students play sports. 10 ÷ 5 = 2 = 1/5, so 2 × 2 = 4 = 2/5. Your answer is 4 students. I hope this helps!

I'm a little confused, it's about Combining like terms but I did don't understand

ella [17]

2(-n-3)-7(5+2n)

First, you need to distribute the numbers in front of the parentheses to those in the parentheses. This means you multiply.

2 times -n= -2n

2 times -3= -6

-7 times 5= -35

-7 times 2n= -14n

This leaves you with

-2n -6 -35 -14n

Next, combine like terms.

(-2n) + (-14n)= -16n
(-35) + (-6)= -41

This gives you

-16n-41, which is B in your answer choices.

Hope this makes sense!! :)
