Answer:
n= -6
Step-by-step explanation:
Simplifying
4 + -7n = -1(8n + 4) + 2
Reorder the terms:
4 + -7n = -1(4 + 8n) + 2
4 + -7n = (4 * -1 + 8n * -1) + 2
4 + -7n = (-4 + -8n) + 2
Reorder the terms:
4 + -7n = -4 + 2 + -8n
Combine like terms: -4 + 2 = -2
4 + -7n = -2 + -8n
Solving
4 + -7n = -2 + -8n
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '8n' to each side of the equation.
4 + -7n + 8n = -2 + -8n + 8n
Combine like terms: -7n + 8n = 1n
4 + 1n = -2 + -8n + 8n
Combine like terms: -8n + 8n = 0
4 + 1n = -2 + 0
4 + 1n = -2
Add '-4' to each side of the equation.
4 + -4 + 1n = -2 + -4
Combine like terms: 4 + -4 = 0
0 + 1n = -2 + -4
1n = -2 + -4
Combine like terms: -2 + -4 = -6
1n = -6
Divide each side by '1'.
n = -6
Simplifying
n = -6
Answer:
<h2>
Sales price of jeans is $35</h2>
Step-by-step explanation:
Step one:
given
percentage of discount= 30%
Regular price of jeans= $49.99
Required:
the price of the jeans after the discount is deducted
Step two;
let us solve for the amount of the 30% discount
=30/100*49.99
=0.3*49.99
=14.997
=$15 approx.
Hence the deduction in discount is $15
therefore the sale price after the discount is
=49.99-15
=$35
Answer:
The length of the arc shown in red is 
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to

we have

substitute


step 2
Find the length of the arc in red
Remember that the length of the circumference subtends a central angle of 360 degrees
so
by proportion find the length of the arc by a central angle of 110 degrees

Simplify
