Answer:
Step-by-step explanation:
Hi there,
To solve this problem, we will need to isolate the variable by moving the variable to one side and the number to the other side.
1. - 16.5v - 19.94 = 19.39 - 9.6v <em>Rewrite the problem</em>
2. - 16.5v = 39.33 - 9.6v <em>Move the non-variable number to one side</em>
3. -6.9v = 39.33 <em>Isolate the variable</em>
4. v = - 5.7 <em>Divide by -6.9</em>
Thus, we can see the answer to this problem is v = - 5.7.
Have a good day,
Jamie
Answer:
Step-by-step explanation:
<u>We know that:</u>
- Given expression: 7xy - x²t + 4xy + 5x²t
<u>Solution:</u>
- 7xy - x²t + 4xy + 5x²t
- => 11xy - x²t + 5x²t
- => 11xy + 4x²t
Hence, the simplified expression is 11xy + 4x²t.
Answer:
88
Step-by-step explanation:
We have 4 numbers that sum to 354.
So, let us use a letter to represent the first consecutive number in the sum.
Let it be x.
x + (x + 1) + (x + 2) + (x + 3) = 354
We want (x + 1), the second number in the sequence.
Simplify x + (x + 1) + (x + 2) + (x + 3) = 354
x + (x + 1) + (x + 2) + (x + 3) = 4x + 6 = 354
4x + 6 = 354
4x = 354 - 6
4x = 348
x = 348/4 = 87
so x + 1 = 87 + 1 = 88
First do 25+6=31
Then you do 25+10=35
Answer:
1. 12 2. 12 3. 13.2 4. 13.2
Step-by-step explanation:
the first one is 12, by 20*0.6
the second problem is 12
the third problem is 13.2
so fourth one is also 13.2
