I assume we are writing the equation. The sum of a number and 14 is less than or equal to three times the number.
Let's put in a few values.
The sum of a number = x and + 14 is less than < or equal to = three times 3 * the number.
Now we have: x + 14 is < or = 3 * the number.
We can just remove the "is" and "or", because this is normal math patterns.
x + 14 <= 3 * the number.
"The Number" is referring to the "a number" at the very beginning. So we can replace that with the same variable.
x + 14 <= 3x
Answer:
X = 54
Step-by-step explanation:
Let's solve your equation step-by-step.
1/2x−4=1/3x+5
Step 1: Subtract 1/3x from both sides.
1/2x−4−1/3x=1/3x+5−1/3x
1/6x−4=5
Step 2: Add 4 to both sides.
1/6x−4+4=5+4
1/6x=9
Step 3: Multiply both sides by 6.
6*(1/6x)=(6)*(9)
x=54
The 2nd one i'm pretty sure i did it with a calculator
Answer:
I think the answer is 13
Step-by-step explanation:
You have to start by adding 4/5 in order to get x alone. When you add 4/5 and 6/13, you have to find the smallest number that both the fractions can have as the same number in the denominator. For this case it is 5 because 13 times two, three, or four won't equal a number that 5 times any whole number can equal. 13 times 5 is 65 and 6 times 5 is 30 so our new fraction is 30/65. For 4/5 we do the same. In order for the bottom number to equal 65, you have to multiple the fraction by 13. 5 times 13 is 65 and 4 times 13 is 52 so our new fraction is 52/65. We now add 52/65 and 30/65 to get 82/65!
