Answer:

( -2 , 1 )

Step-by-step explanation:

Add the 2 equations downwards.

( -x+4y=6 ) + ( 2x-y=-5 )...consider the sign of each term.

= x + 3y = 1

Put -2 in x because that's where the graph above shows an intersection of the 2 equations.

-2 + 3y = 1

3y = 3

y = 1.

( x , y) = ( -2 , 1 )

Answer:

x = -91/10

Step-by-step explanation:

-2(5x + 8) = 14 + 61

-10x -16 = 75

-10x = 91

-10x/-10 = 91/-10

x = -91/10

Answer: The second option would be the answer

Step-by-step explanation:

Factoring the number is just listing all the whole numbers it can be divided by, and in this case it includes the variable. 16a is dividable by 1, 2, 4, 8, 16, and a; since 16a / a = 16. Apply this to 18b, and 1, 2, 3, 6, 9, 18, and b.

Let's Solve:

-Chetan K

Answer:

A

Step-by-step explanation:

2 x 4 = 8

3 x 4 = 12

2/3 = 8/12

Step-by-step explanation:

Let's solve your system by elimination.

3k−4m=−1;2k+3m=12

Multiply the first equation by 3,and multiply the second equation by 4.

3(3k−4m=−1)

4(2k+3m=12)

Becomes:

9k−12m=−3

8k+12m=48

Add these equations to eliminate m:

17k=45

Then solve17k=45for k:

17k=45

----

17k

=17

45

17

(Divide both sides by 17)

k=

Now that we've found k let's plug it back in to solve for m.

Write down an original equation:

3k−4m=−1

Substitute

forkin3k−4m=−1:

(Add (-135)/17 to both sides)

(Divide both sides by -4)

Given :

⠀

To Find :

⠀

Solution :

We know that,

[tex]\qquad { \pmb{ \bf{Length \times Width = Area_{(rectangle)}}}}\: [/tex]

So,

Let's assume the width of the rectangle as x and the length will be (x + 2).

⠀

Now, Substituting the given values in the formula :

[tex]\qquad \sf \: { \dashrightarrow (x + 2) \times x = 48 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} + 2x = 48 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} + 2x - 48 = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} +8x -6x- 48 = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x} (x +8) -6(x+8) = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow (x +8) (x - 6) = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow x = -8, \: \: x = 6 }[/tex]

⠀

Since, The width can't be negative, so the width will be 6 which is positive.

⠀

[tex]\qquad { \pmb{ \bf{ Width _{(rectangle)} = 6\:ft}}}\: [/tex]

[tex]\qquad { \pmb{ \bf{ Length _{(rectangle)} = 6+2=8 \: ft}}}\: [/tex]

Answer: 32

Step-by-step explanation:

We can write the problem like this:

[tex]\frac{75}{100}x=24[/tex]

Then, we can multiply 100 to the equation:

[tex]75x=2400[/tex]

Now, we can divide 2400 and 75:

[tex]x=32[/tex]

Now we can conclude that the amount of students is 32.

9 bags sorry for the other answer

she has 7 boxes at home, then she goes and buys 6 more from the store, now she has 7 + 6 = 13 boxes of chips, each box of chip has 13 bags, so the total amount of potato chips I guess is 13 * 13 = 169 bags total.

So she split it even among her 9 students, so how many times does 9 go into 169?  169 ÷ 9, has a quotient of 18 with a remainder of 7.

18 * 9 = 162, plus 7 = 169, which is the total amount of potato chips bags.

Answer:

decompose

numerator

mixed number

Step-by-step explanation:

1. To DECOMPOSE is to break apart a number.

e.g. to decompose 853:  800 + 50 + 3

2. The NUMERATOR is the top number in a fraction (the bottom number is the denominator).

3. A number that has whole number part and fraction part is a MIXED NUMBER, e.g. [tex]6\frac23[/tex]

Using the normal distribution and the central limit theorem, it is found that there is a:

a) 0.1813 = 18.13% probability that a person selected at random will score between 240 and 270 on the test.

b) 0.4501 = 45.01% probability that the mean score for the sample will be between 240 and 270.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

Item a:

The probability is the p-value of Z when X = 270 subtracted by the p-value of Z when X = 240, hence:

X = 270:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{270 - 250}{65}[/tex]

[tex]Z = 0.31[/tex]

[tex]Z = 0.31[/tex] has a p-value of 0.6217.

X = 240:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{240 - 250}{65}[/tex]

[tex]Z = -0.15[/tex]

[tex]Z = -0.15[/tex] has a p-value of 0.4404.

0.6217 - 0.4404 = 0.1813.

0.1813 = 18.13% probability that a person selected at random will score between 240 and 270 on the test.

Item b:

We have a sample of 7, hence:

[tex]n = 7, s = \frac{65}{\sqrt{7}} = 24.57[/tex]

X = 270:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{270 - 250}{24.57}[/tex]

[tex]Z = 0.81[/tex]

[tex]Z = 0.81[/tex] has a p-value of 0.7910.

X = 240:

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{240 - 250}{24.57}[/tex]

[tex]Z = -0.41[/tex]

[tex]Z = -0.41[/tex] has a p-value of 0.3409.

0.7910 - 0.3409 = 0.4501.

0.4501 = 45.01% probability that the mean score for the sample will be between 240 and 270.

numbers divisible by 2 end with an even number (2,4,6,8,0)

numbers divisible by 5 end with either 5 or 0

Answer:

A,D, and F

Step-by-step explanation:

Any number that is even is divisible by 2.

A D and F are even numbers. If a number ends in 2,4,6,8, or 0 then it is an even number, so you can just look at the last number and determine weather it is divisible by 2.
