The first mistake was in the 6x + 14 = -4 Line as -12x + 6x is -6x and not 6x.

there is 8 boys for every 5 girls in the 6th grade class, if there are 169 total students how many boys are there? How many girls? Write the ratio. *

Answers

Answer:

Boys : 104

Girls : 65

We know:

For every 8 boys there is 5 girls so the ratio is:

8 : 5

There are 169 total students

We are going to take these students as cookies and how many of them we are going to bake in batches

Step-by-step explanation:

Add 8 and 5 together to find out how many students in each 'Batch' 8 + 5 = 13

Then divide 169 by 13 which equals 13. Now you know how many 'Batches' there are.

To find the answer Multiply 13 by 8 and 5 ;

13 * 8 = 104

13 * 5 = 65

Check the answer:

104 + 65 = 169

Solve for a. Show (All steps must be shown): -2(a-3)=12

Answers

Answer:

a= -3

Step-by-step explanation:

first distrubute the parenthesis -2(a-3)

-2a+ 6= 12

then move the like terms

6 becomes -6 and subtract to both sides so 6-6 cancels out and you are left with 12-6 which gives you 6

then you have -2a = 6

lastly divide on both sides and you get

-2a÷ -2 (cancels out)

6÷ -2

and the answer is

a= -3

Answers

Answer:B have it ✅

Step-by-step explanation:

The value of x for the given equilateral triangle is 28.

What is an equilateral triangle?

A triangle having all sides equal and each angle measures 60° is called

an equilateral triangle.

Given that, the measure of each angle in an equilateral triangle is represented by the expression 2x + 4.

We know that each angle in an equilateral triangle measures 60°

Therefore, 2x+4= 60

2x = 56

x = 28

Hence, the value of x is 28.

If 23 is added to a number, the result is 41 less than twice the number. Find the number.

Answers

Answer:

64

Step-by-step explanation:

Let x represent the number.

x + 23 represents 23 added to the number.

2x - 41 represents 41 less than twice the number.

Set these expressions equal to each other and solve for x to find the number:

x + 23 = 2x - 41

23 = x - 41

64 = x

So, the number is 64

Answers

Answer. -15
Explanation. We know that a positive multiplied by a negative (or vice versa) equals a negative. If it’s confusing, you can even take out the negative and add it at the end. Remember, 1 negative means the answer is negative, 2 negatives means the answer is positive, and two positives are just positive (this is used for multiplication and division ONLY). So, to solve, 5•3 is 15, and just make it negative, -15!

Solve for n -3n-5=16

Answers

Answer:

n = -7

Step-by-step explanation:

Solve for n:

-3 n - 5 = 16

Hint: | Isolate terms with n to the left-hand side.

Add 5 to both sides:

(5 - 5) - 3 n = 5 + 16

Hint: | Look for the difference of two identical terms.

5 - 5 = 0:

-3 n = 16 + 5

Hint: | Evaluate 16 + 5.

16 + 5 = 21:

-3 n = 21

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -3 n = 21 by -3:

(-3 n)/(-3) = 21/(-3)

Hint: | Any nonzero number divided by itself is one.

(-3)/(-3) = 1:

n = 21/(-3)

Hint: | Reduce 21/(-3) to lowest terms. Start by finding the GCD of 21 and -3.

The gcd of 21 and -3 is 3, so 21/(-3) = (3×7)/(3 (-1)) = 3/3×7/(-1) = 7/(-1):

n = 7/(-1)

Hint: | Simplify the sign of 7/(-1).

Multiply numerator and denominator of 7/(-1) by -1:

Answer: n = -7

Answer:

n = -7

Step-by-step explanation:

Add 5 to each side, so it now looks like this: -3n = 21Divide each side by -3 to cancel out the -3 next to n. It should now look like this: n = -7
