Answer:

Brand A

Step-by-step explanation: Brand A because y=50x+100 and that equals 150x. For brand B y=25x+200 and that equals 225x. So Brand A is lower.

Answer:

(3,1)

m=2

Answer:

Number of catfish = 28

Step-by-step explanation:

Let the number of catfish = c

Number of angle fish = c + 6

Number of guppies = 4*(c + 6) = 4c + 4*6 = 4c + 24

Total fishes = 198

c + c + 6 + 4c + 24 = 198           {Combine like terms}

c + c +4c + 6 + 24 = 198

                6c + 30 = 198              {Subtract 30 from both sides}

                     6c    = 198 - 30

                     6c   = 168

                       c = 168/6           {Divide both sides by 6}

                       c = 28

Answer:

option A

Step-by-step explanation:

the arrow goes from 0-5 then another from 5-3

Answer:

w = 18

Step-by-step explanation:

w+6 = 2(w-6)

w+6 = 2w-12

2w-w = 6+12

w = 18

hope it helps

Answer:

[tex] \huge \boxed {w = 18}[/tex]

Step-by-step explanation:

Distribute 2 in the bracket.

[tex]w + 6 = 2w - 12[/tex]

A constant and variable cannot add up or subtract each others. Therefore, move the same term to the same side.

[tex]12 + 6 = 2w - w \\ 18 = w[/tex]

Answer Check

Substitute w = 18 in the equation.

[tex]18 + 6 = 2(18) - 12 \\ 24 = 36 - 12 \\ 24 = 24[/tex]

Therefore w = 18 is the correct answer.

Answer:

4.2 cm

Step-by-step explanation:

Given

Area of parallelogram (A) = 4.2 cm²

base (b) = 1.75 cm

Height (h) = ?

We know

A = b * h

4.2 = 1.75 * h

h = 4.2 / 1.75

H = 2.4 cm

Answer:

C) 70

Step-by-step explanation:

Since they can only spend a maximum of $600, we can fill that in for c. Now, we can solve the equation for n.

600 = 8n + 40

~Subtract 40 to both sides

560 = 8n

~Divide 8 to both sides

70 = n

Answer:

x = 1.7

Step-by-step explanation:

Given

-½ + 5x = 8

Required

Find x

-½ + 5x = 8

Multiply both sides by 2

-1 + 10x = 16

Collect like terms

10x = 16 + 1

10x = 17

Divide both sides by 10

x = 1.7

Answer:

8, and 2

Answer:

There are 8 males in the class and 42 females.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of females.

y is the number of males.

Class of 50 students

This means that [tex]x + y = 50[/tex]

The number of females is 2 more than 5 times the number of males.

This means that [tex]x = 5y + 2[/tex]

So, finding y, the number of males:

[tex]x + y = 50[/tex]

[tex]5y + 2 + y = 50[/tex]

[tex]6y = 48[/tex]

[tex]y = \frac{48}{6}[/tex]

[tex]y = 8[/tex]

Females:

[tex]x = 5y + 2 = 5*8 + 2 = 42[/tex]

There are 8 males in the class and 42 females.

Answer:

The answer is 6

Step-by-step explanation:

First nothing us negative, so multiply 8/4 times 9/3,which is 72/12=6, 6×12 is 72.The reason why it is 9/3 instead of 3/9 is because you are dividing so KCF, keep change flip.

Answer:

Positive 6

Step-by-step explanation:

What you do is:

8 x 9 = 72

-4 x (-3) = 12

72 / 12 = 6
