WINSTONCH [101]3 years ago

Answer:

x = 6/5

Step-by-step explanation:

3x - 3/5 + 2 = 5

<u>Add 3/5 and -2 on both sides.</u>

3x = 5 + 3/5 - 2

3x = 18/5

<u>Divide 3 on both sides.</u>

x = 18/5 ÷ 3

x = 18/15

x = 6/5

Answer:

The value of x in the given equation is 6/5

Step-by-step explanation:

3x - 3/5 + 2 = 5

Combine -3/5 and 2.

3x + 7/5 = 5

Subtract 7/5 from 5.

3x = 18/5

Divide 18/5 by 3.

<u>x = 6/5</u>

To check ourselves, let's pug in 6/5 for x in the equation.

<em>3(6/5) - 3/5 + 2 = 5</em>

<em>18/5 - 3/5 + 2 = 5</em>

<em>15/5 + 2 = 5</em>

<em>3 + 2 = 5</em>

<em>5 = 5</em>

1. Marcus bought a $40.00 tennis racket. He has a coupon for 20% off. The Sales tax where he bought the tennis racket is 6%. a.
jeka94

Answer:

$33.92

Step-by-step explanation:

First, we have to find how much the sale price for the tennis racket is before tax.

100% - 20% = 80%          Marcus has to pay 80% of the original price.

80% * 40 = .8 * 40 = 32

Marcus has to pay $32 for the tennis racket before tax.

6% = .06  (tax percentage)

.06 * 32 = 1.92 ————> tax

Add the tax with the sale price.

32 + 1.92 = 33.92

Marcus has to pay $33.92 for the tennis racket.

I hope this helped and please mark me as brainliest!

ad-work [718]
According to the question requirements 

v= 4/3*pi*r^3

dv/dt = 4*pi*r^2*dr/dt

when 
d= 1.7
r= 0.85
and 
dv/dt = 2

2= 4*pi*(0.85)^2*dr/dtthus the the speed of increasing of the balloon's diameter is 
dr/dt = 1/(2pi*(0.85)^2)

Karen wants to advertise how many chocolate chips are in each big chip cookie at her bakery. she randomly selects a sample of 69
Tomtit [17]

Answer: (10.1989,\ 11.0011)

Step-by-step explanation:

Given : Sample size : n=69

Sample mean : \overline{x}=10.6

Standard deviation : s=1.7

Significance level : \alpha:1-0.95=0.05

Then , Critical value : z_{\alpha/2}=1.96

The formula to confidence interval is given by : -

\overline{x}\pm z_{\alpha/2}\dfrac{s}{\sqrt{n}}\\\\\Rightarrow\ 10.6\pm (1.96)\dfrac{1.7}{\sqrt{69}}\\\\\approx10.6\pm0.4011=(10.6-0.4011,10.6+0.4011)=(10.1989,\ 11.0011)

Hence, the 95% confidence interval for the number of chocolate chips per cookie for big chip cookies= (10.1989,\ 11.0011)
