1. What is the difference between these two expressions
(5+3)*3
(5+3)*9

Answer:

18y-9w+6

Step-by-step explanation:

-3*-6y=18y

-3*3w=-9w

-3-2=6

so, 18y-9w+6

Answer:

18y-9w+6

Step-by-step explanation:

The distributive property tells that because the -3 is outside of the parentheses, we multiply all values inside the parentheses by -3.

So, -6y * -3 is 18y because two negatives cancel out, 3w * -3 equals -9w, and -2 * -3 is 6, again because two negatives cancel each other out.

We put this all together, the parentheses and -3 is removed, and the expression becomes 18y-9w+6.

Hey there!

4(-x + 4) = 12

4(-x) + 4(4) = 12

-4x + 16 = 12

SUBTRACT 16 to BOTH SIDES

-4x + 16 - 16 = 12 - 16

CANCEL out: 16 - 16 because it gives you 0

KEEP: 12 - 16 because it helps solve for the x-value

NEW (temporary) EQUATION: -4x = 12 - 16

12 - 16 = -4

NEW EQUATION: -4x = -4

DIVIDE -4 to BOTH SIDES

-4x/-4 = -4/-4

CANCEL out: -4/-4 (the LEFT side) because that gives you 1

KEEP: -4/-4 (the RIGHT side) because it gives you the result of the x-value

x = -4/-4

x = 1

Therefore, your answer is: x = 1

Good luck on your assignment and enjoy your day!

Answer:

the third one is the correct answer

The more convenient method to solve the given system of equations is by elimination.

From the question, we are to determine whether it would be more convenient to solve the system of equations by substitution or elimination

The given system of equations is

2 = 4y - 10     ----------- (1)

7x +12y = 7    ----------- (2)

In equation (1), we can see that there is no variable x in the equation. Thus we can solve for y and then substitute the value of y into equation (2).

That is,

From equation (1)

2 = 4y - 10

2 + 10 = 4y

12 = 4y

12/4 = 4y/4

3 = y

∴ y = 3

Now, we can substitute the value of y into equation (2) to determine the value of x

Hence, the more convenient method to solve the given system of equations is by elimination.

Answer:

[tex] \frac{4x - 1}{2} = x + 7 \\ 4x - 1 = 2(x + 7) \\ 4x - 1 = 2x + 14 \\ 4x - 2x = 1 + 14 \\ 2x = 15 \\ x = \frac{15}{2} \: or \: x = 7.5[/tex]

The probability that none of the selected adults say that they were too young to get tattoos is 0.3512

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

14​% say that they were too young when they got their tattoos.

So, p= 0.14.

Six adults who regret getting tattoos are randomly​ selected

So, n=6.

Now, the probability that none of the selected adults say that they were too young to get tattoos.

P(X=0) = [tex]C_ {6.0} (0.14)^{0} (0.86)^{6}[/tex]

             = 0.3512

a)

The sides of small squares are x and y, therefore the side of the big square is x + y.

The shaded region has an area:

b)

After the dimension changes the new side lengths are:

Since x and y are integers greater than 1, the minimum value of x is 2 (x = 1 doesn't work as we get negative value of x - 2) and same of y is 3 as y > x.

With this the smallest possible area of the shaded region is:

Answer:

Table 1 (leftmost)

Step-by-step explanation:

A linear function has a common difference between all of the x-values. This means that all the x-values change by the same amount relative to the change in y. In this case, the x-value increases by 1/2 every time that y increases by 1. The other tables do not work because their change is inconsistent. There is no number being added each time. Therefore, they are not linear. If you were to graph these tables, only table 1 would make a straight line.

Answer:

94  boys and 56 girls.

Step-by-step explanation:

150/8 = 18.75 = x

b=x*5 = 94

g=x*3 = 56

b+g=150

Looking at the question, we see that the ratio of boys to girls is 5:3, the total is 8. We are trying to find what the ratio of boys to girls is while the total is 150. Now, we can easily divide 150 by 8, finding one part of our answer! 150 ÷ 8 ≈ 18 [tex]\frac{3}{4}[/tex]. now to multiply that by the amount of boys and girls (5:3), 18 [tex]\frac{3}{4}[/tex]  × 5 = 93  [tex]\frac{3}{4}[/tex]  and 18 [tex]\frac{3}{4}[/tex] × 3 =  56 [tex]\frac{1}{4}[/tex]. After we round we get 94:56.

Answer: 700 Hamburgers

Answer:

I believe the answer is 700

Answer:

Step-by-step explanation:

While I can not give you the exact answer as it is a graph, it's worth noting that the function is in f(x) = mx + b form.

This means the first point with an x coordinate of 0 will start at 6, and for each increase in one on the x-axis, we add 2.4.

So, the first coordinate is (0,6), the next is (1,8.4), and so on until you reach the end. That shouldn't take very long provided you can compute addition mentally.

Hope this helps and Good Luck
