Given: 5n-42=12n prove: n=-6
Answer:
n=-6
Step-by-step explanation:
5n-42=12n
5n=12n+24
5n-12n=42
-7n=42
divide each side by -7
n does =-6
The required proof for n = -6 is given in the solution.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
The given equation is,
5n - 42 = 12n
Taking alike terms together we get,
5n - 12n = 42
Solving we get,
-7n = 42
Dividing both the side by -7 we get,
-7n/-7 = 42/-7
Solving we get,
n = -6
Hence we get the required proof.
Thus, the required proof for n = -6 is given in the solution.

4. An attorney charges $250 for a
consultation fee plus $100 per hour of
service. How many hours did he work in
order for his total bill to be $3500?
Answer:
The attorney worked for 32.5 hours in order for his total bill to be $3,500.
Step-by-step explanation:
Let's set up an equation with some variables:
[tex]h[/tex] = hours of service
[tex]T[/tex] = total bill
[tex]T=100h+250[/tex]
Plugging in our given values, we get:
[tex]3500=100h+250[/tex]
And solving for [tex]h[/tex], the hours the attorney worked, we get:
[tex]h=32.5[/tex]
what are the solutions of 4(x+6)^2=52 select two answers
A) √13 - 6
B) -19
C) -√13-6
D)-2√13-6
E)2√13-6
Answer:
A and C
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x2+48x+144=52
Step 2: Subtract 52 from both sides.
4x2+48x+144−52=52−52
4x2+48x+92=0
For this equation: a=4, b=48, c=92
4x2+48x+92=0
Step 3: Use quadratic formula with a=4, b=48, c=92.
x=−48±√832/8
x=−6+√13 or x=−6−√13
Line s has an equation of y=-1/7x-10. Parallel to line s is line t, which passes through the point (9,-2). What is the equation of line t?
Answer:
y = -1/7x + 5/7
Step-by-step explanation:
The slope of a parallel line is the same as the original.
Find the new y-intercept.
y = -1/7x + b
-2 = -1/7(9) + b
-2 = -9/7 + b
5/7 = b
y = -1/7x + 5/7

can someone please help me answer this question?
Answer:
D. A 90° clockwise rotation about the origin
16.827 to the nearest whole.
Answer:
17
Step-by-step explanation:
We want to round 16.827 to the nearest whole number.
When we round a number to the nearest place value, we always look at the digit in the place value to its right.
Here, we're technically rounding to the nearest ones place, so look at the tenths place. It's an 8. Remember that we round up if the digit is 5-9 and round down if the digit is 0-4.
Since it's 8, we round up. Thus, 16.827 rounds up to 17.

number of apples. After eating 1 apple from each bag, she had 28 apples
left. What is the value of x? *
Answer:
There were 8 apples in each bag
Step-by-step explanation:
28 plus 4 is 32
32 divided by 4 is 8
there were 8 apples in each bag before she ate from each one.
2. Sara went to the store to buy 3 apples, 1 cabbage and four, 2-Liter of sodas. She has $15.47 with her.

What is the measure of angle b?
Answer:
angle b is 93 degrees
Step-by-step explanation:
lol i don't think this is how you're expected to do it at all but using what i know about lines and triangles, i can conclude that:
1. the angle that is across left of 44 is 43 degrees because 180-137 is 43. a straight line is equal to 180.
2. from this i can say that b is 93 because 43+44 is 87 and 180-87 is 93. all angles in a triangle tally up to 180.
im sure you're expected to use the same side and adjacent angles theorem, but im pretty sure this'll give you the same answer. hope this helps :)
x + 3 > -2(9-2x) simplify the expression
Answer:
X >4 x − 21
Step-by-step explanation:
rewrite each problem so that x appears on only one side
Answer:
x = -5/21
Step-by-step explanation:
Step 1: Write equation
2(12x - 1) = (21x - 49)/7
Step 2: Solve for x
Multiply both sides by 7: 14(12x - 1) = 21x - 49Distribute 14: 168x - 14 = 21x - 49Subtract 21x on both sides: 147x - 14 = -49Add 14 to both sides: 147x = -35Divide both sides by 147: x = -5/21
