Answer:
4
Step-by-step explanation:
use the distace formula:
square root of (x2-x1)^2 + (y2-y1)^2

D 2:1, because a dime is worth twice as much as a nickel
Because the question has number of nickels listed first in the ratio that makes the answer 2:1 as opposed to B 1:2. Also, two nickels equal the same amount as one dime so for every two nickels there is one dime. In this case, there are 728 nickels and 364 dimes. 728/364 = 2/1 (simplifies down to the fourth ratio given)
Answer:
h = 3
Step-by-step explanation:
Step 1: Write out equation
(6h + 8) - (3h + 2) = 15
Step 2: Distribute negative
6h + 8 - 3h - 2 = 15
Step 3: Combine like terms
3h + 6 = 15
Step 4: Subtract 6 on both sides
3h = 9
Step 5: Divide both sides by 3
h = 3
Step 6: Check Step
(6(3) + 8) - (3(3) + 2) = 15
(18 + 8) - (9 + 2) = 15
26 - 11 = 15
15 = 15
Answer:
Step-by-step explanation:
<h3>#1</h3>
- a) equation
- b) one variable
- c) one variable
- d) linear inequality in 2 variables, t and r
<h3>#2</h3>
<h3>#3</h3>
- a) < less than
- b) > more than
- c) ≤ less than or equal
- d) ≥ more than or equal
For number 8, to solve for x you have to isolate it by dividing both sides of the equation by b. This will give you x=c/b. (Always see if you can do addition/subtraction so you don't get confused and then do multiplication/division. In this case you didn't need to add or subtract anything so you were able to just divide).
For number 9, again you have to isolate the variable p. Start be subtracting kn from both sides of the equation. The operation between m and p is multiplication. The opposite of this is division so divide both sides of the equation by m. Your answer should be p=(q-kn)/m.
For number 10, you're trying to isolate r so start by subtracting b. Now divide both sides by the b next to the r. Your answer should be r=(a-b)/b.
For number 11, you want t by itself so start by subtracting the p that's by itself. Now divide pr from both sides. Your answer should be t=(A-p)/pr.
For number 12, you want y by itself. All you have to do for this one is add b/m to the other side of the equation. Your answer should be y=x+(b/m).
Finally for number 13, you want to isolate p by multiplying both sides of the equation by q. Your answer should be p=q(m/n).
