Consider the equation 5x+10=30 and 5(x+10)=30 Do they have the same solution? Why or why not?

Answers

5x+10=30                               5(x+10)=30 
    - 10  -10                              5x + 50 = 30
 
5x = 20                                         -50    -50

x = 4                                          5x = - 20
                                                      x = -4

They do not have the same solutions because  4 is not equal to -4

These two equations do not have the same solution. x = 4 for the first equation and x = -4 for the second equation.

Why are both equation different?

In the equation 5x + 10 = 30, we are adding 10 to the product of 5 and x. To find x, we can first subtract 10 from both sides of the equation to get 5x = 20. Then we divide both sides of the equation by 5 to solve for x, giving us x = 4.

5x + 10 = 30

5x = 30 - 10

5x = 20

x = 20/5 = 4

In the equation 5(x + 10) = 30, we are first adding x and 10 together, then multiplying the result by 5. To solve for x, we can start by dividing both sides of the equation by 5 to get x + 10 = 6. Then we subtract 10 from both sides to solve for x, giving us x = -4.

5(x + 10) = 30,

5x + 50 = 30

5x = 30 - 50

5x = -20

x = -20/5 = -4

Alexandra is two years older than brad. cecilia is three years younger than alexandra. all three ages added together gives a total of 37 years. how old is each student?

Answers

Let us say that:

x = age of brad

x + 2 = age of Alexandra

(x + 2) – 3 = age of Cecilia = x – 1

 

We are also given that:

x + x + 2 + x – 1 = 37


solving for x:

3x + 1 = 37

3x = 36

x = 12 = age of brad

x + 2 = 14 = age of Alexandra

x – 1 = 11 = age of cecilia

A rectangle has a length of 9.00 inches and a width of 4.25 inches. What is the area in square inches? Round to the correct significant digits. DO I ADD UNITS?????

Answers

Both numbers (9.00 and 4.25) have three sig-figs. This means that the final answer will have three sig-figs as well.

Multiply the numbers to get: 9.00*4.25 = 38.25 which rounds to 38.3 because the answer must have three sig-figs. 

The units will be "square inches" or "inches^2" or "in^2". There are various ways to write the units portion.

Overall, the final answer is 38.3 square inches

You randomly select one card from a​ 52-card deck. find the probability of selecting a blackblack twotwo or a blackblack eighteight

Answers

Since there are 26 black cards (1/2 of 52) and 2 black twos (one for each suite, and there are 2 black/red suites), we can use the same logic to get that there are 2 black eights. 2+2=4, and since there are 52 cards, you have a 4/52 or 1/13 (we get this because 4 goes into 52 13 times) chance of getting a black 8 or 2.

Erin is 8 years younger than twice Paula’s age. The sum of their ages is 40. How old is Erin

Answers

You do the sum(40) subtracted by 8, the answer from that divided by 2 since Erin's two times younger.
40-8=32
32÷2=16
Then if you want to check it you do the opposite and get the same sum(40) so 16×2=32 and 32+8=40
Final answer:

To solve this problem, we set up two linear equations based on the given information and solved them simultaneously. We found that Erin's age is 24 years.

Explanation:

This problem is a classic example of a linear equation. We can set up two equations based on the information given:

Erin is 8 years younger than twice Paula’s age. This can be written as E = 2P - 8.The sum of their ages is 40. This can be written as E + P = 40.

Upon substituting the value of E (Erin's age) from the first equation into the second, we get: 2P - 8 + P = 40. Simplifying this gives P = 16. Substituting P = 16 into the first equation, we find E = 24. Therefore, Erin is 24 years old.

A segment with endpoints X (6, 2) and Y (- 1, - 3) is rotated 90º about the origin. What are the coordinates of X Prime and Y Prime?

Answers

Final answer:

A segment with endpoints X (6, 2) and Y (- 1, - 3) when rotated 90 degrees about the origin will result in new endpoints X' (-2, 6) and Y' (3, -1).

Explanation:

This problem deals with the concept of point rotation in a 2D coordinate plane around the origin. When any point (X, Y) is rotated 90 degrees counter-clockwise about the origin, the new position, let's say (X', Y'), can be calculated by using the formulas X' = -Y and Y' = X. Therefore, applying these rotations to the points X(6,2) and Y(-1,-3), we get X'(-2, 6) and Y' (3, -1). So, the endpoints X Prime and Y Prime of the rotated segment are (-2, 6) and (3, -1) respectively.

Final answer:

After rotating a 90-degree rotation about the origin, the coordinates of X (6, 2) and Y (-1, -3) transform to X' (-2, 6) and Y' (3, -1) respectively.

Explanation:

When a point (x, y) is rotated 90º counterclockwise about the origin, it transforms to (-y, x). Let's apply this rule to the endpoints X (6, 2) and Y (-1, -3).

The coordinates of X prime would be (-2, 6) that is, (-y, x).

The coordinates of Y prime would be (3, -1) that is, (-y, x).

Thus, the transformed coordinates for X and Y would be (-2, 6) and (3, -1) respectively after a 90-degree rotation about the origin.

Brad makes his own snack mix using whole grain cereal and mixed nuts. One batch of his recipe makes 6 cups of snack mix. Brad uses 3 times as much cereal as mixed nuts. The system below can be used to find the number of cups of cereal and number of cups of mixed nuts Brad uses to make one batch of snack mix.


Which describes the ingredients Brad uses to make one batch of snack mix?

Answers

let
c = cereal
m = mixed nuts
c = 3m
c + m = 6
3m + m = 6
4m = 6
m = 6/4
m = 3/2 or 1 &1/2 cup
then c = 3m
c = 3(3/2)
c = 9/2 or 4 &1/2 cup

Answer:

The answer is 4.5 cups of cereal and 1.5 cups of mixed nuts

Step-by-step explanation:

Let 'c' be the number of cups of cereal.

Let 'n' be the number of cups of mixed nuts.

One batch of his recipe makes 6 cups of snack mix, so equation becomes:

[tex]c+ n=6[/tex]     ..... (1)

Also given that Brad uses 3 times as much cereal as mixed nuts, so equation becomes:

[tex]c=3n[/tex]     ......(2)

Substituting (2) in (1)

[tex]3n+n=6[/tex]

=> [tex]4n=6[/tex]

=> [tex]n=1.5[/tex]

Since c = 3n, then

[tex]c=3*1.5=4.5[/tex]

So, the answer is 4.5 cups of cereal and 1.5 cups of mixed nuts.
