In the triangle below, x= cm round to the nearest tenth

Answer:

80

Step-by-step explanation:

First of all, before you do anything to compute the answer, you can see that there is (–13/100) on both sides of the equation. You can cancel them out, since they're the same thing.

Now, you're left with:

[tex]0.8 = \frac{}{100}[/tex]

This is also read as 0.8 is the same thing as [how many] hundredths.

You should know that 0.8 = eight tenths.

So if you move the decimal point right once, you'll get:

0.80

Which is also eighty hundredths.

Your answer would be:

[tex]0.8 = \frac{80}{100}[/tex]

which is 80.

To check your answer, you can also do:

80/100

Because the fraction bar can also be read as "divided by."

You will get 0.8.

Answer:

n = 36

Step-by-step explanation:

4 : 5 = n : 45

It can be also written as :-

[tex]\frac{4}{5} = \frac{n}{45}[/tex]

Multiplying both the sides by 45 ,

[tex]=> \frac{4}{5} \times 45 = \frac{n}{45} \times 45[/tex]

[tex]=> n = 4 \times 9 = 36[/tex]

Answer:

x = 2

Step-by-step explanation:

5 - x  = 7 - 2x

-x + 2x = 7 - 5

x = 2

Answer:

x=2

Step-by-step explanation:

5-x=7-2x

5+x=7 (Move 2x to the other side)

x=2 (Minus 5 from both sides)

Check:

5-x=7-2x

5-2=3

7-(2*2)= 7-4 = 3

(Correct)

Answer:

y = 42 + 7x

Step-by-step explanation:

y=42+7x is the equation  that models the temperature​ y, in degrees​ Fahrenheit, after x hours.

Two or more expressions with an Equal sign is called as Equation.

Given that the temperature at sunrise is 42°F.

Each​ hour, the temperature rises 7°F.

We need to find the equation that models the temperature​ y, in degrees​ Fahrenheit, after x hours.

y=42+7x is the equation  that models the temperature​ y, in degrees​ Fahrenheit, after x hours.

We have to draw the graph by taking few points.

x     0    1      2       3

y    42   49   56    63

Hence, y=42+7x is the equation  that models the temperature​ y, in degrees​ Fahrenheit, after x hours.

Step-by-step explanation:

you would start by subtracting $18.25 from the total $40, which leaves you with $21.75

you then do 21.75 ÷ (divided by) 0.34

that gives you 63.971, and you can only buy whole sheets of paper, you round to 63 and thats your answer

Answer

x>21.2

Step-by-step explanation:

7.55x+100>160:

subtract 100 on both sides to get:

7.55x>60:

divide 7.55 on both sides:

x>21.2 is your answer  

Answer:

7.50h + 100 > 160

Step-by-step explanation:

7.50 is the hourly wage

h = hours he worked

add 100 once because it's his tips for the amount of time her worked

since he worked more than 160, you'll use the greater sign

then solve for h

h = 8 hours
