Answer: x = 6

Step-by-step explanation: To solve for <em>x</em> in this equation, we want to get <em>x</em> by itself on the left side of the equation.

Since <em>x</em> is being multiplied by 3, to get <em>x</em> by itself, we need to divide by 3 on the left side of the equation. Since we divide by 3 on the left side, we must also divide by 3 on the right side. On the left side, notice that the 3's cancel out so we are simply left with <em>x</em>. On the right side, we have 18 divided by 3 which is 6 so we have <em>x = 6</em>.

Finally, remember to check your answer by substituting a 6 back into the original equation. So we have 3(6) = 18 which is a true statement so our answer, <em>x = 6</em>, is correct. <em>Image if provided below</em>.

There are 165 counters in a bag. Each counter is either black or white.

Nostrana [21]

6:5

there are 165 counters in the bag.

let the white counter be x

the black counter = 2x

2x + x = 165

3x=165

divide both sides by 3

x=55

there are 55 white counters in the bag

165-55=110

OR

2x= 165

divide both sides by 2

x= 110

there are 110 black counters in the bag
Martine takes 40%of the black counter

40%= 40/100×110

= 44.

44 black counters was taken out of the bag
then there would be 66 black counters left I.e(110-44=66)

▪︎ there would be 66 black and 55 white counters in the bag.

ratio of black counters to the white counter = 66:55
reduced to the lowest term = 6:5 ( 11 divides 66 and 55 Into 6 and 5)

• the answer is 6:5

What is the radical expression that is equivalent to the expression 27 1/5? Enter your answer as a radical. For example, if your

yuradex [85]

Answer:

$27^{\frac{1}{5} }=\sqrt[5]{3^3}$

Step-by-step explanation:

we are given

$27^{\frac{1}{5} }$

we can use rule to change exponent into radical

$\sqrt[n]{a} =a^{\frac{1}{n} }$

so, we can write as

$27^{\frac{1}{5}}=(3\times 3\times 3)^{\frac{1}{5}}$

$27^{\frac{1}{5}}=(3^3)^{\frac{1}{5}}$

now, we can use rule

and we can write our term as

$27^{\frac{1}{5} }=\sqrt[5]{3^3}$
