You would round 762 to 800, then you would round 332 to 300. You would take those 2 numbers and put them in the questions and it should look like this:
800-300, then you would subtract
Good luck!
Answer:
Jack - $28
David - $17
Step-by-step explanation:
Jack has 2d-6 where d is David's money. David has d money. Together they have 45 and we add the two together.
2d-6+d=45
3d-6=45
3d=51
d=$17
We can then substitute back and find 2(17)-6=34-6=$28.
Answer: 18°F
Step-by-step explanation: if you add 21 and -3 you get 18
Answer:a=4
Step-by-step explanation:
Simplifying
4a + -5 + 2a + 9 = 28
Reorder the terms:
-5 + 9 + 4a + 2a = 28
Combine like terms: -5 + 9 = 4
4 + 4a + 2a = 28
Combine like terms: 4a + 2a = 6a
4 + 6a = 28
Solving
4 + 6a = 28
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + 6a = 28 + -4
Combine like terms: 4 + -4 = 0
0 + 6a = 28 + -4
6a = 28 + -4
Combine like terms: 28 + -4 = 24
6a = 24
Divide each side by '6'.
a = 4
Simplifying
a = 4
Answer:
y=25/6
Step-by-step explanation:
We can set up a proportion!
We know that y/x=y/x because they vary directly.
So, we have 5/6=y/5. We need to solve for y.
We cross multiply and get:
6y=25
y=25/6
When x equals 5, y will equal 25/6.
Hope this helps
