Solve for x if y = 3 in the equation 2x + 3y = 12 *

Answers

Answer 1

Answer:

x = 3/2 or 1.5

Step-by-step explanation:

y = 3 in the equation 2x + 3y = 12

Substitute 3 in for y.

2x + 3(3) = 12

Multiply.

2x + 9 = 12

Subtract 9 from both sides.

2x + 9 - 9 = 12 - 9

2x = 3

Divide both sides by 2.

2x ÷ 2 = x

3 ÷ 2 = 3/2 or 1.5

x = 1.5

Answer 2

Answer:

X = 1.5

Step-by-step explanation:

So we know that Y = 3 and 3 x 3 = 9, then we need to get the difference of 9 to 12

12 - 9 = 3

we now know that x will equal 3, so 2 x 1.5 = 3, and 3 + 9 = 12

(Full equation)

2 x 1.5 + 3 x 3 = 12

A frog jumps 9 3/5 feet in the span of 2 2/3 seconds. Express as a complex fraction and then find the unit rate, in feet per second, that the frog is moving at. Express any improper fractions as mixed numbers.

Answers

Answer:

3 3/5 feet per seconds

Step-by-step explanation:

If a frog jumps 9 3/5 feet in the span of 2 2/3 second, we want to calculate the number of feet it can jump in one seconds.

Since it jumps 9 3/5 feet in the span of 2 2/3 second, we can express this as:

9 3/5 feet  = 2 seconds ... 1

The number of feet per seconds will be expressed as:

x = 1secs.... 2

Divide equation 1 by 2 as shown:

9 3/5 ÷ x = 2 2/3 ÷ 1

48/5x = 8/3

Cross multiply

5x * 8 = 48 * 3

40x = 144

10x = 36

5x = 18

x = 18/5

Express as a mixed fraction:

18/5 = 3 3/5ft/secs

Hence the frog is moving at 3 3/5 feet per seconds

Slope of the line that passes through (6,0) and (0,-6)

Answers

Hey there!

The formula is:

• m = rise / run

• m = y₂ – y₁ / x₂ – x₁

• y₂ = –6

• y₁ = 0

• x₂ = 0

• x₁ = 6

• Equation: “–6 – 0 / 0 – 6”

–6 – 0 = –6 ⬅️ numerator (TOP number)

0 – 6 = –6 ⬅️ denominator (BOTTOM number)

Equation: –6 / –6

SOLVE above and you will have your ANSWER.

–6 / –6 = 1 because double negatives makes a negative.

What is the probability that a customer ordered a cold drink given that he or she ordered a large?

Answers

Answer:

19

Step-by-step explanation:

The probability that a customer ordered a cold drink given that he or she ordered a large is 32%.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

P(Small | Cold) = n(Small and Cold)/n(Cold)

From the table:

P(Small | Cold) = 8/(8 + 12 + 5)

P(Small | Cold) = 0.32

or

P(Small | Cold) = 32%

Thus, the probability that a customer ordered a cold drink given that he or she ordered a large is 32%.

Eugene sold half of his comic books and then bought eight more. He now has 32. With how many did he begin?

Answers

Answer:

48 books

Step-by-step explanation:

32-8 = 24

24= 1/2 of total

24x2=48

Answer=48 books

Check:

48/2=24

24+8=32

YAY!!

Answer:

48 comic books

Step-by-step explanation:

Let's use x as the amount that he originally had.

If he sold half of them, that would be:

(1/2)x

Then he bought 8 more, so you would add 8 to that total.

(1/2)x + 8

If he now has 32 then we need to set that equation to equal 32.

(1/2)x + 8 = 32

Subtract 8 from each side.

(1/2)x = 24

Then you will divide 24 by 1/2. That is the same thing as multiplying by 2.

So,

x = 48

Check work

(1/2)x + 8 = 32

(1/2)(48) + 8 = 32

Half of 48 is 24.

24 + 8 = 32.

32 = 32.

If z>0, what is the quotient of 20√z6 ÷ √16z7 in simplest radical form

Answers

Answer:

5√z/z

Step-by-step explanation:

i took the test(:

The quotient of [tex]20\sqrt{z^{6} }[/tex] ÷ [tex]\sqrt{16z^{7} }[/tex] in simplest radical form is  [tex]\frac{5\sqrt{z} }{z}[/tex].

How to express a simplest radical form?

Expressing in simplest radical form just means simplifying a radical so that there are no more square roots, cube roots, 4th roots, etc left to find. It also means removing any radicals in the denominator of a fraction.

Given

[tex]20\sqrt{z^{6} }[/tex] ÷ [tex]\sqrt{16z^{7} }[/tex]

Rewrite as fraction: [tex]\frac{20\sqrt{z^{6} } }{\sqrt{16z^{7} } }[/tex]

Factor and rewrite the radicand in exponential form: [tex]\frac{20\sqrt{z^{6} } }{\sqrt{4^{2}. z^{6} .z} }[/tex]

Rewrite the expression using [tex]\sqrt[n]{ab} =\sqrt[n]{a} \sqrt[n]{b}[/tex] :

= [tex]\frac{20\sqrt{z^{6} } }{\sqrt{4^{2} .\sqrt{z^{6}.\sqrt{z} } } }[/tex]

Simply the radical expression, we get:

= [tex]\frac{20z^{3} }{4z^{3}\sqrt{z} }[/tex]

Reduce fraction to the lowest term by canceling the greater common factor, we get

= [tex]\frac{5}{\sqrt{z} }[/tex]

Rationalize the denominator

= [tex]\frac{5\sqrt{z} }{\sqrt{z} .\sqrt{z} }[/tex]

= [tex]\frac{5\sqrt{z} }{z}[/tex]

Hence, the quotient of [tex]20\sqrt{z^{6} }[/tex] ÷ [tex]\sqrt{16z^{7} }[/tex] in simplest radical form is  [tex]\frac{5\sqrt{z} }{z}[/tex].

If Aaron tunes into his favorite radio station at a randomly selected time, there is a 0.20 probability that a commercial will be playing.

b. If Aaron tunes into this station at 5 randomly selected times, will there be exactly one time when a commercial is playing?

Answers

Answer:

Yes, there will be with a probability of 0.4096

Step-by-step explanation:

Given,

p = 0.2

1 - p = 0.8

Number of trials, n = 5

P(x = 1)

Using the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

P(x = 1) = 5C1 * 0.2^1 * 0.8^4

P(x = 1) = 5 * 0.2^1 * 0.8^4

P(x = 1) = 0.4096

Yes, there will be with a probability of 0.4096

No. If Aaron tunes into this station at 5 randomly selected times, there will not necessarily be exactly one time when a commercial is playing.

Fiona, Peter and Angad share some sweets in the ratio 5:1:2. Fiona gets 33 more sweets than Angad. How many sweets are there altogether?

Answers

33/3=11
1 portion=11
5x11=55
11x1=11
2x11=22
55+11+22=88
ANSWER: 88 sweets in total

For every 5 sweets Fiona has, Peter has 1 sweet and Angad has 2 sweets.

If Fiona has 33 more, that means each of the 8 portions contains 11 sweets.

5-2 = 3
33/3 = 11

Fiona has 55 sweets.
Peter has 11 sweets.
Fiona has 22 sweets.

5x11 = 55
1x11 = 11
2x11 = 22

55+11+22 = 88 sweets in total
