Solve the equation. Show the process, not just an answer. 6.EE.7
1) 4k = 24
2) 34 + h = 60
3) 1/5x = 30
4) m-42 = 85

Answers

Isolate the variable, note the equal sign, what you do to one side, you do to the other.

1) 4k = 24

Isolate the variable, k. Divide 4 from both sides of the equation:

(4k)/4 = (24)/4

k = 24/4

k = 6

2) 34 + h = 60

Isolate the variable, h. Subtract 34 from both sides of the equation:

34 (-34) + h = 60 (-34)

h = 60 - 34

h = 26

3) 1/5x = 30

Isolate the variable, x. Multiply 5 to both sides of the equation:

(5) * (1/5)x = (30) * (5)

x = 30 * 5

x = 150

4) m - 42 = 85

Isolate the variable, m. Add 42 to both sides of the equation:

m- 42 (+42) = 85 (+42)

m = 85 + 42

m = 127

Find the area of the figure.
7 cm
8 cm
11 cm
The area is
square centimeters.

Answers

Answer:

let's divide the figure in rectangle and triangle.

first we should find the area of triangle.

area of triangle =1/2×base×height

area of triangle=1/2×11cm×7cm

area of triangle=38.5cm²

area of rectangle =length ×width

area of rectangle =11cm×8cm

area of rectangle =88cm²

area of the figure=38.5cm²+88cm²

area of the figure=126.5cm²

The number that has 1/10th the value of 0.3 is 0.03.

Each place value to the left of a decimal place is 10x the value of the one closer to the decimal, and each place value to the right of a decimal is 1/10th the value of the place closer.

Answer:  D) 2.33 meters

==========================================================

Explanation:

The hundredths digit is 1/10 of the tenths digit. Because of this, the tenths and hundredths digit must be the same digit.

Only choice D fits the description.

The digit in the tenths place represents the value 0.3

Taking 1/10th of this leads to (1/10)*0.3 = 0.1*0.3 = 0.03

So the hundredths place represents the value 0.03

Note that,

2 + 0.3 + 0.03 = 2.33 meters

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

given that,

At 12 p.m., the number of cars in a parking lot is 67.

It is estimated that the number of cars in the parking lot will decrease by 8% each hour.

so, we get,

Given,

at first the number of cars in a parking lot is = 67

now, it is decreasing by 8% each hour.

So, for any hours , let after 'n' hours,

the number will be = 67 * (100 - 8)%×n

                               =67 * 92%×n

A woman wishes to rent a house within 9 miles of her work. If she lives x miles from her work, her transportation cost will be cx dollars per year, while her rent will be 4c/( x + 1) dollars per year, where c is a constant taking various situational factors into account. How far should she live from work to minimize her combined expenses for rent and transportation? Use the methods outlined in this section to find the minimum.

Answers

Answer:

the woman has to live 1 mile from work to minimize the expenses

Step-by-step explanation:

Given the data in the question;

the distance within 9 miles ⇒ 0 < x > 9

Total costs Q = cx + 4c/( x + 1)

costs should be minimum  ⇒ dQ/dx = 0

⇒ d/dx [ cx + 4c/( x + 1) ] = 0

⇒ ( x + 1)² = 4

take square root of both side

√[ ( x + 1)² ] = √4

x + 1 = 2

x = 2 - 1

x = 1

Therefore, the woman has to live 1 mile from work to minimize the expenses
