Answer: -3.5 or -3 1/2

Step-by-step explanation: Put in the numbers -3 and 5 for the variables and simplify, (-2)-3 -2(5) -1/6(-3), to get 6 - 10 + 1/2(or 0.5), then add and subtract, 6-10= -4 + 0.5 = -3.5 or -3 1/2.

Answer:

35/128

Step-by-step explanation:

7 coins are tossed, each coin has two possibilities therefore total number of possibilities are 2^7 = 128. The possibilities of obtaining 4 heads and 3 tails is 7C4 = 7C3 = 35. Therefore the probability of obtaining 4 heads and 3 tails 35/128.

Answer:

When adding integers with the same sign, the sum is equal to the sum of the absolute values of each addend and has the sign common to the addends. Both addends are positive, so the sum is positive. Both addends are negative, so the sum is negative

Answer:

D

Step-by-step explanation:

The equation can be used to find q is 0.05(84 - q) + 0.25q = 17.80 option (D) 0.05(84 - q) + 0.25q = 17.80 is correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

Alex has 84 quarters and nickels worth a total of $17.80.

As we know,

1 nickel = 5 cents

1 dime = 10 cents

1 quarter = 25 cents

1 dollar = 100 cents

The amount that Alex = 84 quarters + $17.80

q = 84 quarters + $17.80

q is the number of quarters Alex has.

Remaining nickel value = 84 - q

In cents:

= 0.05(84 - q)

q in cents:

= 0.25q

0.05(84 - q) + 0.25q = 17.80

Thus, the equation can be used to find q is 0.05(84 - q) + 0.25q = 17.80 option (D) 0.05(84 - q) + 0.25q = 17.80 is correct.

Answer: -48x^7 y^3

Step-by-step explanation: Simplify the expression.

I hope this helps you out. :)

Answer:

Intercepts in terms of graphing are considered to be points at which a function crosses an axis.  In the standard x and y graph (the Cartesian coordinate grid), one would find the intercepts by simply plugging in the value of 0 for either the x or the y to find either the y or x intercept respectively.  For example, to find the y-intercept, you want to find (0,y) and to find the x-intercept, you want to find (x,0).

Greetings from Brasil....

Let's solve this 2nd degree equation.

6b² + 8b - 10 = 0       dividing all terms by 2

3b² + 4b - 5 = 0         applying the baskara formula

Δ = 4² - 4 · 3 · (- 5)

Δ = 76

b = (- 4 ± √76)/6      so

The value of y is 27. (first option.)

isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

27

Step-by-step explanation:

2(3y + 6 +3)

2(9 + 3y)

18 + 6y

18 + 6y = 196 -16

6y =196 -16 -18  

6y = 162

162 divided by 6 = 27

y =27

Division is one of the four fundamental arithmetic operations. The number of batches of cookies to make from a bag of flour is 40.

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that a bag of flour contains ten cups of flour. And one batch requires 1/4 cup of flour. Therefore, we can write,

The number of cups of flour in a bag = 10 cups of flour

The number of cups required to make one batch of cookies = 1/4 cup of flour

The number of batches of cookies can be made with a  bag of flour is,

Number of Batches = 10 cups of flour / 1/4 cup of flour per batch

                                = 40 batches

Thus, the number of batches of cookies to make from a bag of flour is 40.

Step-by-step explanation:

-4.5x -2y = -12.5 -------(1)

3.25x -y = -0.75 --------(2)

From (2) we can make y the subject of the relation

y = 0.75+3.25x -------(3)

Input 0.75+3.25x into y in (1)

-4.5x -2(0.75+3.25x) = -12.5

-4.5x -1.5- 6.5x = -12.5

-4.5x -6.5x -1.5 = -12.5

-11x = -12.5 +1.5

-11x = -11

x = 11/11

x = 1

If x = 1,substitute 1 into x in (3)

y = 0.75+3.25x

y = 0.75 +3.25(1)

y = 0.75 +3.25

y = 4

x = 1,y = 4

Answer:

37.5 miles per hour

Step-by-step explanation:

To find the miles per hour, you divide the miles by hours. If you divide 225/6, you get 37.5. You can double check this by dividing another set, like 450/12 and see that you still get 37.5. Hope this helps! :)
