1) -3x -3 -7x = 17
• start by grouping so add -3x and -7x which gives you -10x
• 10x -3 (+3) = 17 +3 = 20 add 3 on both sides)
• 10x (/10) = 20/ 10 = 2
1) x = 2
2) 10x -6 (+6) = 24 + 6 = 30
• 10x (/10) = 30/ 10 = 3
2) x = 3
3) -4 (+4) -5x = -39 +4 = -35
• -5x (/-5) = -35/ -5 = 7
3) x = 7
4) 3x - 5 > 10
this one i don’t understand, is there a typo maybe ?
5) -5x + x + 16 = -3 you can put a 1 to hold the place of x to make it 1x
• (-5x + 1x) + 16 = -3
• -4x + 16 (-16) = -3 -16 = -19
• -4x (/-4) = -19/ -4 = 4.75 or 4 3/4
5) x = 4.75
SOLUTION
From the question, we are told that y varies inversely as x
This is mathematically written as
Now, we will remove the proportionality sign and replace it with equal to sign =
If we do this, we will intoduce a constant k
So we have the formula
We will substitute the values of x for 10 and y for 8 into the formula to get k, we have
Now, we will substitute k for 80 back into the formula to get the inverse function, we have
Hence the answer is option C
Answer:
The sum of the interior angles of any triangle is equal to 180 degrees.
Answer:
9c - 13
Step-by-step explanation:
Given
3(c - 7) + 2(3c + 4) ← distribute both parenthesis
= 3c - 21 + 6c + 8 ← collect like terms
= 9c - 13
Answer: 2/25
Step-by-step explanation:
8% means 8/100
To reduce to the simplest fraction, divide through with a common factor of 4
Divide numerator by 4 = 2
Divide denominator by 4 = 25
Therefore, 8% = 2/25
I hope this helps.
