Jin raised 40$ since it was his goal and he reached it
Simplifying
37 + 8x = 4(7 + -1x)
37 + 8x = (7 * 4 + -1x * 4)
37 + 8x = (28 + -4x)
Solving
37 + 8x = 28 + -4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4x' to each side of the equation.
37 + 8x + 4x = 28 + -4x + 4x
Combine like terms: 8x + 4x = 12x
37 + 12x = 28 + -4x + 4x
Combine like terms: -4x + 4x = 0
37 + 12x = 28 + 0
37 + 12x = 28
Add '-37' to each side of the equation.
37 + -37 + 12x = 28 + -37
Combine like terms: 37 + -37 = 0
0 + 12x = 28 + -37
12x = 28 + -37
Combine like terms: 28 + -37 = -9
12x = -9
Divide each side by '12'.
x = -0.75
Simplifying
x = -0.75
Answer:
20%
Step-by-step explanation:
First, find the difference between $130 and $104. This equals $26, and to find this discount written as a percent, divide $26 by the original cost of the camera. 26/130=0.2, which represents a 20% discount.
Answer:
or 
Step-by-step explanation:
step 1
Find the slope of the line
The formula to calculate the slope between two points is equal to
we have the ordered pairs
(3,-5) and (1,-9)
substitute the values
step 2
Find the equation in point slope form
Analyze two cases
<em>First case</em>
we have
substitute
<em>Second case</em>
we have
substitute
Note: The equation of the line in point slope form varies according to the point you choose, in contrast to the slope-intercept form
Answer:
3 × 5 × 5 × 2 × 2 × 2
Step-by-step explanation:
Make a factor tree.
But let me explain the above to prove it's correct.
3 × 5 = 15
15 × 5 = 75
75 × 2 = 150
150 × 2 = 300
300 × 2 = 600
Therefore 600 as a product of prime factors is: <u>3 × 5 × 5 × 2 × 2 × 2</u>
