The answer is A.First we substitute 8 into the given equation.
Multiply 8 and 5, then find the square root of 40. Finally multiply it by 10.
Then add 15.
And the answer will be 78.245.
Now the question says that s is in
thousands, so the real answer would be about 75,000.
Solve for x
6x+5y=-15
subtract 6x from both sides
5y=-6x-15
divide both sides by 5
y=-6/5x-3
Answer:
Equation: 14 + x = 16
The unknown variable: x = 2
Step-by-step explanation:
The sum of 14 and a number x:
14 + x
is equal to 16
14 + x = 16
14 + x = 16
x = 16 - 14
x = 2
<em>C) 20 points</em>
- Step-by-step explanation:
<em>James - 5</em>
<em>Richard + 15</em>
<em>What is the difference in their scores ?</em>
<em>+ 15 - (- 5) =</em>
<em>= 15 + 5</em>
<em>= 20 points</em>
Always follow the rules of BOMDAS. (If you don't know them or maybe learned differently tell me).
Firstly multiply 4(1/2) and then substract
8 - 4(1/2)
8 - 2
6
Hope this helps :).
