What does x equal 3/4(x+9)=15

2 answers:

6 0

To solve this problem, we will use the distributive property.
3/4(x + 9) = 15
3/4x + 6.75 = 15
Now we will subtract 6.75 from both sides of the equation.
3/4x = 8.25
To get rid of the fraction, we will multiply 8.25 by 4, then divide it by 3.
3/4x • 4 ÷ 3 = 8.25 • 4 ÷ 3
x = 11
Another way to do this would be to divide 3 by 4 and write .75x, then divide .75 into 8.25. It would still get us 11.
In this equation, x is equal to 11.

Miche found that most helicopters fly at speeds of less than 270 kilometers per hour. Her work is shown below. s > 270 A numb

almond37 [142]

Answer:

The inequality should be s<270.
The number line should be shaded to the left.

Step-by-step explanation:

Miche found that most helicopters fly at speeds of less than 270 kilometers per hour.

If s=speed of the helicopters

Then: s<270

Representing this on a number line:

We have an open circle at 270.

Everything to the left of the circle is shaded.

Since the options are not given, I would list the mistakes made by Miche.

The inequality should be s<270.
The number line should be shaded to the left.

Explain how to estimate the quotient using compatible numbers. 27 and two-thirds divided by 3 and StartFraction 9 over 10

melisa1 [442]

Answer:

Step-by-step explanation:

Given:

27 + 2/3 ÷ 3 + 9/10

In division, compatible numbers are numbers that can be divided mentally.

27 + 2/3 ÷ 3 + 9/10

27 + 0.67 ÷ 3 + 0.9

27.67 ÷ 3.9

= 7.0948717948717

Approximately

= 7

But, alternatively

27.67 ÷ 3.9

27.67 is closer to 28

3.9 is closer to 4

Therefore,

28 ÷ 4

= 7

The quotient of 27 + 2/3 ÷ 3 + 9/10 using compatible numbers is around 7
