100 POINTS!! Express in radical form.
Vilka [71]

Answer:

27   4th root (x^3)

Step-by-step explanation:

(81x) ^ 3/4

We know (ab) ^c = a^c b^c

81 ^ (3/4)  * x^3/4

We can rewrite 81 as 3^4

(3^4)^(3/4)  * x^3/4

We know that a^b^c = a^ (b*c)

3^(4*3/4)  * x^3/4

3^(3) * x^3/4

27  * x^3/4

27   4th root (x^3)

2.1(2.3 + 2.1x) = 11.65 + x. Step by step equation please help
DedPeter [7]

Answer:

x=2

Step-by-step explanation:

2.1(2.3 + 2.1x) = 11.65 + x

Distribute

4.83+4.41x=11.65+x

bring 4.83 over (-)

4.41x=6.82+x

bring x over

4.41x-1(x)=6.82

4.41-1=3.41 so

3.41x=6.82

divide 3.41

x=2

Your company recently made a purchase of 25 identical tables. The purchase price after adding 5 percent sales tax was 1,706.25.
ELEN [110]
If c = the cost of one table, the cost of all 25 tables before sales tax is 25·c

Since the sales tax is 5%, or 0.05, the sales tax for 25 tables is 25·c·0.05

Adding the sales tax to the original cost of the 25 tables can give you:
25·c + 25·c·0.05 = 1706.25
1.05·25·c = 1706.25
26.25·c = 1706.25
c = \frac{1706.25}{26.25} = 65

so the refund for 5 tables would be 5*65 = $325

Help plssssssss, thank you
IRINA_888 [86]

Answer:

x = 14

Step-by-step explanation:

Given

- \frac{1}{5}(x - 4) = - 2

Multiply both sides by 5 to eliminate the fraction

- (x - 4) = - 10 ← distribute parenthesis by - 1

- x + 4 = - 10 ( subtract 4 from both sides )

- x = - 14 ( multiply both sides by - 1 )

x = 14
