Answer:
substitution method would go as follows
5x-2=7x-8 we than rearange it so it becomes 5x-7x=-8-2 this than becomes -2x=-6 so x=3
we can than substitute 3 for x in one of the first equations
y=7 times 3-8 = 21-8 = 13
so therfore the interception should be at 3,13

Ming incorrectly says that this product is 4/63.
-(-4/9) · (-1/7)
a. What is the correct product?
b. What error could Ming have made?
Answer: -4/63
Step-by-step explanation: he put a positive sign instead of a negative in the 4
a. The correct product is -4/63.
b. Ming forgot to distribute two negative signs on the first term.
Sign changes when we do arithmetic operations ?(-,-) = +. (+,+) = +. (-,+) = -. (+,-) = -.
For example -: 6 + (-3) here negative sign of 3 will distribute (+,-) and the end result will be negative ⇒ 6 - 3 = 3
According to the given question
Ming has given a product -(-4/9) · (-1/7) and he mistakenly said it is 4/63.
The given product is -(-4/9) · (-1/7)
= (4/9).(-1/7)
= -4/63.
Ming didn't notice that on the first term two negative sign will distribute and make it positive and then multiplying it with a negative number will result in a negative number.

Answer:
The cost of the avocadoes is dependent because it relies on the number of avocados. The number of avocados is independent because it can stand alone. So the costs are dependent and the numbers (1, 2, 3, 4, 5) are independent. c= 1.25a is neither dependent or independent but is put in there because it can be an equation used to solve how much the cost is for a number of avocados.

The width of a computer monitor is 28 cm. If the perimeter is 136 cm, what is the area of the computer monitor?
A. 896cm 2
B. 812 cm2
C.1,020 cm2
D. 1,120 cm2
Answer: D. 1,120 cm2
Step-by-step explanation: Perimeter is the adding of all four sides, so if you take the width and add it with itself, you can then subtract the perimeter with the added width. Now with this new number all you have to do is divide it by two, and now that you have the length you can multiply it with the original width to get the area.

Raul’s grandfather is Miguel, and Raul’s sister is Paula. Raul’s age is the same as his grandfather’s age minus 60 times the age of his sister. Miguel is 65 years old. Using the results from Part C, write an equation to find Paula’s age, p (in years).
Previous equation answer:
Yes the values are the same
3r = 45
3(15) = 45
Answer:
3(15)+60p+65=45
Step-by-step explanation:
Paula’s age, p is 5/6 years.
Given that, Raul’s grandfather is Miguel age=65 years.
How do solve age problems?Important Statements and Equations for "Problems based on Ages":
If the present age is y, then n times the present age = ny.If the present age is x, then age n years later/hence = x + n.If the present age is x, then age n years ago = x – n.The ages in a ratio a: b will be ax and bx.If the current age is y, then 1/n of the age is y/n.Let Raul’s sister Paula's age be p and Raul’s age be r.
From the statement, Raul’s age is the same as his grandfather’s age minus 60 times the age of his sister.
We can write the equation as follows r=65-60p
In part C:
39=3r-6
⇒r=15
So using the part C answer we get 15=65-60p
⇒60p=65-15
⇒p=5/6 years
Therefore, Paula’s age, p is 5/6 years.
