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

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?
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.

Harry's school is selling t-shirts to raise money for the archery team. The school will receive 35% of the total sales which can be modeled by the equation y = 0.35x, where x represents the total number of sales. What is the meaning of the x-intercept in the equation?
Answer:
X-intercept states that the graph crosses the x-axis.
Substitute y = 0 and solve for x.
As per the statement:
Harry's school is selling t-shirts to raise money for the archery team.
The school will receive 35% of the total sales which can be modeled by the equation:
y = 0.35x
where, x represents the total number of sales and y represents the total cost of sale.
By definition of x-intercept:
0 = 0.35x
⇒x = 0
Therefore, the x-intercept in the equation represents:
The number of sales when no money has been raised.
The sum of two numbers is 64 . the larger number is 22 more than the smaller number. what are the numbers?
64-22 = 42
42/2 = 21
21+22 = 43
21 + 43 = 64
the numbers are 21 & 43
The larger number is 43 and the smaller number is 21.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The numbers will be calculated as:-
Let the larger number be L and the smaller number be S.
L + S = 64
From the given data the larger number is 22 more than the smaller number
L = S + 22
Put L = S + 22 in the above equation.
S + 22 + S = 54
2S = 64 -22
2S = 42
S = 42 / 2 = 21
L = S +22 = 21 + 22 = 43
Therefore, the larger number is 43 and the smaller number is 21.

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?
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 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?
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.

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.

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