Answer:
Step-by-step explanation:
Let's start by finding Sandra's salary this year.
We are given that she saved $3,360 or 8% of her total salary this year.
Let's represent her total salary this year as "x" and set up an equation:
Note that any percentage is equivalent to that number over 100.
Multiply 100 to both sides:
Divide both sides by 8
The question states "this year her salary was $2000 more than in the previous year".
This means that her salary in the previous year is equivalent to:
Answer:
Step-by-step explanation:
Given expression which gives the distance is 16t².
Here, t = time or duration
For t = 20 seconds,
16t² = 16(20)²
= 6400 feet
For t = 21 seconds,
16t² = 16(21)²
= 7056 feet
For t = 22 seconds,
16t² = 16(22)²
= 7744 feet
For t = 23 seconds,
16t² = 16(23)²
= 8464 feet
Therefore, complete table will be,
t 20 21 22 23
h 6400 7056 7744 8464
Answer:
y= 2.6
Step-by-step explanation:
Answer:
x = 3.25
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
...and is the order of operation.
First, subtract 3 from both sides of the equation:
4x + 3 = 16
4x + 3 (-3) = 16 (-3)
4x = 16 -3
4x = 13
Next, dvide 4 from both sides:
(4x)/4 = (13)/4
x = 13/4
x = 3.25
x = 3.25 is your answer.

<span>How to graph {8x +6y=48 2x-3y=-6}
The first thing you should do is to clear "y". Then, you must substitute values of x in the equation to find the values of "y". Finally, graph the points obtained. (see graphic)
</span><span> How do you convert this to slope intercept form?
</span> 8x +6y=48 ---> <span>y = -1.3333x + 8
</span> 2x-3y=-6 ---> <span>y = 0.6667x + 2</span>
