Answer:
The values of given expressions are:
1. gh = -21
2. g^2 - h = 46
3. g + h^2 = 2
4. g + h = -4
5. h - g = 10
6. g - h = -10
Step-by-step explanation:
Given values of g and h are:
g = -7
h = 3
<u>1. gh</u>
The two numbers are being multiplied
Putting the values

<u>2. g^2-h</u>
Putting the values

<u>3. g+h^2</u>
Putting the values

<u>4. g+h</u>
Putting the values

<u>5. h-g</u>
Putting the values

<u>6. g-h</u>
Putting values

Hence,
The values of given expressions are:
1. gh = -21
2. g^2 - h = 46
3. g + h^2 = 2
4. g + h = -4
5. h - g = 10
6. g - h = -10
Answer:
5/16
Step-by-step explanation:
15+(5-x)/x=30
1) Subtract 15 from both sides:
(5-x)/x=15
2) Multiply both sides by x:
5-x=15x
3) Add x to both sides:
16x=5
4) Divide both sides by 16:
x=5/16
Answer:8
Step-by-step explanation:
Okay, think of it this way:
You have to find how many times 4,000 goes into 150,000.
This will tell you how many costumes you can buy.
To make this easier, we can divide 4 by 150. (this is proportional to 4,000 and 150,000 since we took 3 zeros from each number; you will get the same answer)
150/4= 37.5
You can buy 37 whole costumes.
Hope this helped!
Answer:
37.5
Step-by-step explanation:
the triangle is enlarged by a factor of 2.5 so you multiply all of the numbers in XYZ by 2.5 then add them
15+10+12.5=37.5 units
