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

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:

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: 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

Answer:

=2x2−3x−8

Step-by-step explanation:

Let's simplify step-by-step.

2x2+7x−4−10x−4

=2x2+7x+−4+−10x+−4

Combine Like Terms:

=2x2+7x+−4+−10x+−4

=(2x2)+(7x+−10x)+(−4+−4)

=2x2+−3x+−8

Answer:

=2x2−3x−8

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

3.5 or 7/2 if you need a fraction

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

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.

Step-by-step explanation:

i think 5= 25 divided 5 or 2 decimal point

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:

251.64 I think it's correct but im not 100% sure

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:

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.
