The two numbers would be -0.8 and -7.2
You have to find the common denominator which is 4 and multiply 26 by 4 which equals 104 add 3 which is 107 and divide by 4
Answer:107/4
Answer:
12150 ft^3
Step-by-step explanation:
= (45)(20)(10) + (350)(9)
= 9000 + 3150
= 12150 ft^3
Answer:
18
Step-by-step explanation:
6 2 1 How many ways does this produce and are they legitimate?
- 6 2 1
- 6 1 2
- 2 6 1
- 2 1 6
- 1 2 6
- 1 6 2
So any combination that you come up with, will produce 6 variations within those three choices. They are legitimate.
Lets see what you get with at most 5 estates to one person
5 3 1 Which will also give 6 variations. There are no other ways to make 5
4 3 2 Which will give 6 variations
I don't think there are any more possible choices.
Are the only 3 ways the estates can be split given the rules. Each choice leads to 6 other choices. The total is 18
Answer:
x= 1.5, y= 3.5
or x= -5, y= 10
Step-by-step explanation:
Let's solve by substitution.
Label the two equations:
y= 2x² +6x -10 -----(1)
y= -x +5 -----(2)
Substitute (2) into (1):
2x² +6x -10= -x +5
2x² +6x +x -10 -5= 0
Simplify:
2x² +7x -15= 0
Factorise:
(2x -3)(x +5)= 0
2x -3= 0 or x +5= 0
2x= 3 or x= -5
x= 1.5
Now that we have found the value of x, we can find the value of y through substitution.
Substitute into (2):
y= -1.5 +5 or y= -(-5) +5
y= 3.5 or y= 10
