What are the steps to find x

Mathematics
1 answer:
AveGali [126]3 years ago

40 = 2x + 7

First, subtract 7 on both sides so you can get the variable on one side:

40 = 2x + 7
-7           -7
33 = 2x

Now, divide both sides by 2 to isolate x:

33 = 2x
33/2 = x

Hope this helps!

Hank's pickup can travel 72 miles on 4 gallons of gas. How many gallons will Hank's pickup need to travel 54 miles?
Ira Lisetskai [31]

Answer:

3 gallons of gas

Step-by-step explanation:

First we need to create the ratio to build our answer off of.

This ratio would be 72:4, meaning 72 miles for every 4 gallons.

We can divide 72 by 4 to find the unit rate.

72 / 4 = 18

So, the unit rate is 18 miles for every 1 gallon.

Next we need to figure out how may gallons are needed to travel 54 miles.

We can divide 54 by 18 to receive 3.

This means that our ratio needed to answer the question is 3 times the unit rate.

Our new ratio is now: 54:m, m meaning miles.

To find the amount of miles, multiply the 3 we used later, to make this ratio 3 times the unit rate.

So, our final ratio is 54:3,

meaning that Hank will have used 3 gallons of gas after traveling 54 miles.

The company financial officer was interested in the average cost of PCs that had been purchased in the past six months. She took
SpyIntel [72]

Answer:

$1,482 is the 10th percentile.

Step-by-step explanation:

xth percentile:

If a measure is said to be in the xth percentile, it means that x% of the measures are smaller than it, and (100-x)% are larger.

In this question:

10 computers, the 10th percentile is the value that is larger than 10% of the prices.

The prices, sorted in an increasing way, are:

$1,127, $1,482, ...

Computers at a price of $1,482 have larger prices than 10% of the population, so $1,482 is the 10th percentile.

Estimate the part of the garden that is planted with tomatoes. Explain how you decided.
strojnjashka [21]

Answer:

Therefore tomatoes\hspace{0.1cm} patch = \frac{3}{8}\hspace{0.1cm}of\hspace{0.1cm} garden

Step-by-step explanation:

i) from the figure shown pumpkins and lettuce seem to make up half of the of the garden

ii) the other half of the garden seems to be tomatoes and cucumber.

iii) tomatoes seems to be 3 times that of cucumber.

iv) therefore we can say that tomatoes would make up three fourths of half of the garden which would equal to three eights of the garden.

tomatoes\hspace{0.1cm} patch = \frac{3}{8}\hspace{0.1cm}of\hspace{0.1cm} garden

What is the value of x in the equation below?
denis23 [38]

Answer:

Step-by-step explanation:

Alright, lets get started.

The given equation is :

1+2e^{x+1}=9

Subtracting 1 in both sides

1+2e^{x+1}-1=9-1

2e^{x+1}=8

Dividing 2 in both sides

e^{x+1}=\frac{8}{2}

e^{x+1}=4

Taking log on both sides

loge^{(x+1)}=log4

(x+1)loge=log4

Plugging the value of log e as 1

x+1=log4

x=log4-1   ..................... Answer

Hope it will help :)
