Answer: 2y - 20z = -16

Step-by-step explanation:

6(2x+y-3z) = 5(6)

=> 12x + 6y- 18z = 30

3(2x + 3y + z) = 13(3)

=> 6x + 9y + 3z = 39

Now minus the top equation from the bottom two:

12x + 6y - 18z = 30

6x + 9y + 3z = 39

6x - 5y - z = 7

12x + 6y - 18z = 30

12x + 4y + 2z = 46

Minus top from bottom:

2y - 20z = -16

Answer:

Answer:

Step-by-step explanation:

3/8 (left over - from party) of 3/4 : 3/4 of 3/8 = 9/32

Answer:

a=2, b=2, c=-12

Step-by-step explanation:

Since it's in factor form, you would first distribute using foil to get [tex]2x^{2} -4x+6x-12[/tex] and then combine like terms when necessary. In this case, the fully simplified version is [tex]2x^{2} +2x-12[/tex]. Therefore your a is 2, b is 2, and c is -12.

Answer:

33.33

Step-by-step explanation:

Answer:

$33.3333333333 or 33 dollars and 33 cents

Step-by-step explanation:

Convert 1/6 into a decimal

which is 0.16666666666667

then do 200 times 0.16666666666667

and you get 33.3333333333

Alt:

200 times 1 divided by 6

which is also 33.3333333333

Answer:

In the left box, type: 2 In the right box, type: 3

Step-by-step explanation:

1/3(4a + 1) = 1/2a

6{1/3(4a + 1)] = 6(1/2a)

because 6 x 1/3 = 2 and 6 x 1/2 = 3

2(4a + 1) = 3a

Answer:

x=1.46875 or x=1.5

Step-by-step explanation:

1st step subtract 1.8 on both sides

-9.6x=-14.1

2nd step divide -9.6 on both sides

x=1.46875

or

x=1.5

Given:

The system of equation is

[tex]y=-8x-3[/tex]

[tex]x+y=7[/tex]

To find:

Whether (3,4) is a solution of the given system or not.

Solution:

We have,

[tex]y=-8x-3[/tex]          ...(i)

[tex]x+y=7[/tex]            ...(ii)

Putting the value of y in (ii) from (i), we get

[tex]x+(-8x-3)=7[/tex]

[tex]x-8x-3=7[/tex]

[tex]-7x=7+3[/tex]

[tex]-7x=10[/tex]

Divide both sides by -7.

[tex]x=\dfrac{10}{-7}[/tex]

[tex]x=-\dfrac{10}{7}[/tex]

Putting [tex]x=-\dfrac{10}{7}[/tex] in (i), we get

[tex]y=-8\times (\dfrac{-10}{7})-3[/tex]

[tex]y=\dfrac{80}{7}-3[/tex]

[tex]y=\dfrac{80-21}{7}[/tex]

[tex]y=\dfrac{59}{7}[/tex]

So, the only solution of the given system is [tex]\left(-\dfrac{10}{7},\dfrac{59}{7}\right)[/tex].

Hence, (3,4) cannot be a solution of given system, Hence the correct option is B.

Answer:

66.7%

Step-by-step explanation:

Given that,

Weight in first five weeks = 4.5 pounds

Weight at eight weeks = 7.5 pounds

We need to find the increase in precentage. The percentage increase in any value is given by :

[tex]\%=\dfrac{\text{final-initial}}{\text{initial}}\times 100\\\\=\dfrac{7.5-4.5}{4.5}\times 100\\\\=66.7\%[/tex]

So, the increase in precentage is 66.7%.

Answer:

angle ABC is 130 degrees

Step-by-step explanation:

This is the quickest and simplest way to gind the answer.

Angle CBD and angle ABC are linear pairs. Linear pairs are supplementary meaning angle CBD and angle ABC equal 180 degrees. Since angle CBD is 50 degrees and you know both angles need to add up to 180 degrees all you need to do is subtract 180 from 50 degrees.

3.5 or 7/2 if you need a fraction

Its 20 because, 32 -  9 = 23 and your rounding so its 20

Answer:

A. 12

Step-by-step explanation:

$1,150.89 - $200.13 = $950.76

$950.76 / $79.23 weekly = 12 weeks

To check:

12 weeks x $79.23 = $950.76

$950.76 + $200.13 = $1,150.89

Answer: 2205

Step-by-step explanation:

Ratio of the number of students accepted to the number of students applying for admission = 2:7

Number of students accepted = 630 students

Number of students that applied will then be represented by x. This will be:

2/7 = 630/x

2 × x = 630 × 7

2x = 4410

x = 4410/2

x = 2205

The number of students that applied to the university was 2205
