Answer:
the solution would be 10 to the best of my knowledge
The LCD is 12. Thus, your
(x-2)/4 - (x+3)/3 = -2 becomes 12((x-2)/4 - (x+3)/3 = -2), or
3(x-2) - 4(x+3) = -36
Then 3x - 6 - 4x - 12 = -36. Combining like terms,
-x = -36 + 18, or -x = -18, or x = 18.
Check this result by subbing 18 for x in the given equation.
Please note: You must use parentheses here as indicated to eliminate any ambiguity about order of operations and what divides into what.
Answer: The length of each leg of the triangle is 13 units. Have a nice day!
Using Pythagorean theorem, a^2+b^2=c^2
13^2+13^2=26^2
Answer:
x = -2.
y = 3.
Step-by-step explanation:
If y = 3x + 9
Substitute this value for y in the first equation.
4x + 5(3x + 9) = 7
4x + 15x + 45 = 7
19x = 7 - 45
19x = -38
x = -38/19
x = -2.
with this value of x, substitute -2 in the second equation
y = 3(-2) + 9
y = -6+9
y = 3.
check if your values are all correct
4(-2) + 5(3) = 7
-8 + 15 = 15 - 8 = 7
Correct!
Answer:
The answer is 25.07 gallons/ 1 minute
Step-by-step explanation:
The question is asking for the unit rate of 752 gallons/30 minute as related to the minutes. So, you're looking for the ratio of gallons to 1 minute. To solve for this, you must divide the initial ratio of gallons to minutes by the initial minutes. so 752/30 and 30/30. Dividing 30 by 30 will give you 1. So, you know you'll be getting the unit rate. 752/30 is 25.0666666667. However, rounded to the nearest hundred will result in 25.07.
So your answer will be 25.07 gallons/ 1 minute (per minute).
