Which expression is equivalent to 6a + 15?

6(a + 5)
3(2a + 5)
3(3a + 12)
6(a + 12)

Answers

Answer 1
The answer is going to be 3(2a+5)


Explanation:

6(a+b) = 6a +30 (it is not equivalent to 6a+15)

You have to multiply what’s in the brackets by 6

3(2a+5) = 6a+15 ( it is equivalent )


3 (3a+12) = 9a+36 (not equivalent)


6(a+12) = 6a+12 (not equivalent)

Decrease $820 by 32%​

Answers

Answer:

557.6

Step-by-step explanation:

Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

32% = 32/100 = 32 ÷ 100 = 0.32.

100% = 100/100 = 100 ÷ 100 = 1.

Percentage decrease = 32% × 820

New value =

820 - Percentage decrease =

820 - (32% × 820) =

820 - 32% × 820 =

(1 - 32%) × 820 =

(100% - 32%) × 820 =

68% × 820 =

68 ÷ 100 × 820 =

68 × 820 ÷ 100 =

Answers

Answer:

3, 8, 6

Step-by-step explanation:

Please correct me if I am wrong!

The angles that have the same measure as angle 1 are ∠3, ∠6 and ∠8.

What is an angle measure?

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Given:

A traversal line cuts two parallel lines.

So, ∠1 = ∠6. {From the property of opposite angles}.

And ∠1 = ∠3. {From the property of alternate interior angles}.

The property of opposite angles,

∠8 = ∠3.

So, the angle measures that are equal to ∠1 are:

∠3, ∠6 and ∠8.

Therefore, ∠3, ∠6 and ∠8 are the equal angle measures.

Use the Pythagorean theorem to find each missing length to the nearest tenth

Answers

answer: 10.4

explanation: a^2 + b^2 = c^2
plug in 3 for a and 10 for b
3^2 + 10^2 =c^2
simplify to get
109 =c^2
take the square root of both sides
c = sqrt109 or 10.44030651

Answer:

c (the hypotenuse) = 10.4 units

Step-by-step explanation:

Start off by rearranging the original pythangorean theorem (a^2+b^2=c^2) by taking the square root of both sides so it is in the form of a distance formula solving for c(the hypotenuse).

c^2 will become |c| as length cannot be negative so (labeling an absolute value is negligible)

a^2+b^2 = c^2

c^2 = a^2+b^2

√(c^2) = √(a^2+b^2)

c = √(a^2+b^2)

Then substitute the given lengths, in this scenario, sides a and b.

After you substitute, just simplify.

c = √(3^2+10^2) = √(9+100) = √109 ≈ 10.4 units (nearest tenth)

If y varies drectly with x
and y= 4.5 when x= 2.5,
what is y when x= 12?

Answers

You have to figure out what the difference is first , so we can se le that the difference between y and x will always be 2, we got this number by subtracting 4.5-2.5=2.
So we are given x which is 12 so in order to solve this you just substitute x with 2 in the next equation 12+x=y/ 12+2=14

Answers

Answer:

I believe the answer is about 1/2!

Step-by-step explanation:

I don't have a step-by-step but when I took a test this question was on it and I got the question right by putting about 1/2!

The probability of her catching a trout is 6/25

What is probability ?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

According to the question

based on given condition , formulate

24 ÷ (23 + 12 + 24 + 41)

Calculate sum or difference = 24/23 + 12 + 24 + 41

Calculate sum or difference = 24/59 + 41

Calculate sum or difference = 24/100

Reduce the fraction = 6/25

Hence, the probability of her catching a trout is 6/25

There is a bag filled with 5 blue and 6 red marbles.

Another marble is taken at random.
What is the probability of getting at least 1 red?

Answers

Answer:

There are 6+5 marbles.

Of those, 5 are red.

The chances of drawing a red marble are 5/11

Since you replace the marble you drew, the chances each draw remain 5/11

You cannot draw two red marbles without drawing a red marble on your first draw, so the odds of you making a second draw are 5/11. The odds of that also being red are 5/11… but we only care about that 5/11ths the time

Answer:  Casey bought 4 1/2 pounds of apples

The equation is 0.88x - $1.50 = 2.46

x is the unknown number of pounds of apples.

0.88 is the cost per pound,  0.88x is the total cost of the apples before the discount .The discount is $1.50   $2.46 is the cost after the discount.

Part b Step-by-step explanation:

0.88x - $1.50 = 2.46 . Add $1.50 to both sides

0.88x - $1.50 + $1.50 = 2.46 + 1.50  

On left, 1.50-1.50=0 so "cancels'  on the right, add $2.46 + 1.50 = 3.96

0.88x = 3.96  is the cost before discount . Divide both sides by .88

.88x/.88 = 3.96/.88 .  .88/.88 = 1 so 1 'cancels'  leaving x.   3.96/.88 = 4.5

x = 4.5

part c

4.5 is 4 1/2, the (previously unknown) number of pounds of apples.
