Given: 5n-42=12n prove: n=-6

Answers

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.

Answers

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

16.827 to the nearest whole.

Answers

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.

The fourth graders sang on a​ two-day telethon for the local​ children's hospital. The hospital hoped to raise​ $760,000. On day​ one, they raised​ $398,139. On day​ two, they raised​ $376,173. Did they reach their​ goal? About how much more or less did they​ raise? Estimate by rounding to the nearest ten thousand.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Amount hoped to Raise = $760,000

Amount raised on day 1 = $398,139

Amount raised on day 2 = $376,173

Did they reach their​ goal?

Amount raised on day 1 + amount raised on day 2

$398,139 + $376,173 = $774312

Yes, because ;

$774312 > $760,000

$774,312 - $760,000 = $14,312

Amount was surpassed by $14,312

= $14,000 ( to the nearest ten thousand)

(NEED ASAP) what is the measure of ∠b?

Answers

Answer:

b= 140 degrees

Step-by-step explanation:

In order to find it, we must know that a lin has an angle of 180.

So woth that, just used that angle to make an equation of

"40+b=180"

Just subtract 40 on both sides and you get

"b=140"

:D

This a questions about angles! Let's see how to solve it:

In this figure, we have a straight angle. A straight angle is a 180 degree angle. In this case, the straight angle is the sum of 40° and b.

So, we can do an equation and solve it. See below:

[tex]40 + b = 180\\b = 180 - 40\\b = 140[/tex]

Therefore, the measure of [tex]\angle b[/tex] is 140°.

C) -√13-6
D)-2√13-6
E)2√13-6​

Answers

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.

What is the measure of angle b?

Answers

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 :)
