Answer: x < 3

Step-by-step explanation:

To solve this inequality, we will simplify and isolate the x variable.

Given:

5x - 4 < 2x + 5

Add 4 to both sides:

5x < 2x + 9

Subtract 2 from both sides:

3x< + 9

Divide both sides by 3:

x < 3

Answer:

x < 3

Step-by-step explanation:

Well you want to isolate x so start by subtracting 2x from both equations that way you remove it from the right side and it's only on the left side.

subtract 2x from both equations

$3x-4 < 5$

add 4 to both equations

$3x < 9$

divide both sides by 3

$x < 3$

a taxi ride costs 40 dollars for the first 500 meters and each additional 300 meters (or a fraction thereof) adds $3.50 to the f

Colt1911 [192]

Answer:

$ 71.5

Step-by-step explanation:

firstly kilometer to meters

1 km = 1000 m

therefore 3 km = 3000m

for the first 500 = $40

hence deduct the 500 from 3000m

3000 - 500 = 2500

now find out how many 300m go into 2500

2500 / 300 = 8.33

which is rounded up to 9

therefore the total amount is :

40 + 9 * 3.5

= $71.5

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 402 gram setting. It is

lidiya [134]

Answer:

The value of t test statistics is -2.25.

Step-by-step explanation:

We are given that a manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 402 gram setting. It is believed that the machine is under filling the bags.

A 25 bag sample had a mean of 393 grams with a standard deviation of 20.

Let $\mu$ = mean filling of bags by the machine.

So, Null Hypothesis, $H_0$ : $\mu \geq$ 402 gram {means that the the machine is not under filling the bags}

Alternate Hypothesis, $H_A$ : $\mu$ < 402 gram {means that the the machine is under filling the bags}

The test statistics that would be used here One-sample t test statistics as we don't know about the population standard deviation;

T.S. = $\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }$ ~ $t_n_-_1$

where, $\bar X$ = sample mean bag filling = 393 grams

s = sample standard deviation = 20 grams

n = sample of bags = 25

So, test statistics = $\frac{393-402}{\frac{20}{\sqrt{25} } }$ ~ $t_2_4$

= -2.25

The value of t test statistics is -2.25.

If 1116 parts were made in 7 hours how much parts were made an hour

vampirchik [111]

Hello! To solve this question, all you have to do is divide the total amount of parts made by the number of hours. 1116/7 is 159.42857 and other numbers, or 159 when rounded to the nearest whole number. There were about 159 parts made an hour.

Why there must be at least two lines on any given plane

ratelena [41]

Although theoretically there are infinite lines in space and in a plane, too, at least three non collinear points are necessary to define a plane. Two intersecting lines will therefore be necessary to define it (two points create a line); these intersecting lines are the ones to help define coordinates (x,y).
