On the bus there are 42 boys and 30 girls. What is the ratio of girls to boys in SIMPLEST form? Helppp plz

Answer:

7 hours

Step-by-step explanation:

Answer:  3t - 6

Reasoning:

We multiply the outer term 3 by each term inside, which is t and -2

3 times t = 3*t = 3t

3 times -2 = 3*(-2) = -6

Add up those results to get 3t+(-6) = 3t-6

Therefore, 3(t-2) = 3t-6

This is an example of the distribution property.

Answer:

18

Step-by-step explanation:

3(t-2)

3x2=6

(t-6)

^3^

3(6)

3x6= 18

Answer:

46. or 45.5 if not rounded

Step-by-step explanation:

We know she makes $72.85 at selling cookies if she sales 17 cupcakes for $3.25 she'll make $55.25 but were trying to find how many she sales with $1.60 so $72.85 divided by 1.60 is 45.5 and if not then it's 46. rounded.

Step-by-step explanation:

14/7 = 2

So,

-14/7 = -2

Check:

-2 x 7 = -14

Answer:

-2

Step-by-step explanation:

because 7 can go into 14 2 times and since the 14 is negative the answer is negative

Answer: -4c+12

all real numbers

Step-by-step explanation:

6) 28-(3c+4) =2 (c+6)+c

When there is a - in front of an expression in parentheses , change the sign of each term of the expression.

28-3c-4=2(c+6)+c

Distribute 2 through the parentheses

28-3c-4=2c+12+c

Now we do the same thing only different way

2(c+6)

Multiply each term in the parentheses by 2

2c+2×6

Multiply the numbers

2c+12

_____________

28-3c-4=2c+12+c

subtract the numbers

24-3c=2c+12+c

Collect like terms

24-3c=3c+12

It's the same thing only different way ok

2c+c

If a term doesn't have a coefficient , it is considered that the coefficient is 1.

2c+1c

Collect like terms by adding their coefficients

(2+1)c

Add the numbers

3c

________

24-3c=3c+12

Move variable to the left hand side and change its sign

24-3c-3c=12

Move constant to the right  by adding its opposite to both sides

-3c-3c+24-24=12-24

eliminate the opposites

-3c-3c=12-24

Collect like terms

-6c=12-24

Calculate the difference

-6c=-12

so the same thing only different way ok

12-24

Keep the sign of the number with the larger absolute value and subtract the smaller absolute value from the larger.

-(24-12)

Subtract the numbers

-12

__________

-6c=-12

divide both sides of the equation by -6

-6c÷(-6)=-12÷(-6)

Any expression divided by itself equals 1

c=-12÷(-6)

Dividing two negatives equals a positive

(-)÷(-)=(+)

c=12÷6

Calculate the quotient

c=2

Answer:

FV= $22,536.5

Step-by-step explanation:

Giving the following information:

Growth rate (i)= 1% monthly

Present value (PV)= $20,000

Number of periods= 12 months

To calculate how much will the employee earn after a year, we need to use the following formula:

FV= PV*(1+i)^n

FV= 20,000*1.01^12

FV= $22,536.5

Answer:

1

Step-by-step explanation:

The equation of the following line looks like this:

[tex]y=x[/tex]

In this type of line, every single y value corresponds to the given x value. The slope of this line is considered to be positive one, as you can multiply x by one and still get the same number (Identity property)

A constant of proportionality originates from this type of equation:

[tex]y=kx[/tex]

K is the constant, and the number multiplied by x. It can also be recognized as the slope (m)

1st picture (tri) = 16y+8

2nd picture (tri) = 12x-9

3rd picture (sq) = 21x+35

Step-by-step explanation:

Triangle area = (Base x Height) divided by 2

#1.)  16(2y+1) = 32y + 16            (32y+16)/2 = 16y+8

Answer:

a=3 , b=2

Step-by-step explanation:

Answer:

Step-by-step explanation:

Using the distance formula: distance = [tex]\sqrt{(x_{2} -x_{1})^{2}+(y_{2} -y_{1})^{2} }[/tex]

sub it in,

10 = [tex]\sqrt{(10 -2)^{2}+(y-(-3)^{2}}[/tex]

10 = [tex]\sqrt{(8)^{2} +(y+3)^{2}}[/tex]

10 = [tex]\sqrt{64+y^{2} +9+6y}[/tex]

10 = [tex]\sqrt{73+y^{2} +6y}[/tex]

square both sides:

100 = 73 + [tex]y^{2}[/tex] + 6y

[tex]y^{2}[/tex] + 6y = 27

y( y + 6) = 27

y = 27 OR THE OTHER SOLUTION IS y + 6 = 27

y = 21
