Answer:
x = -6
Step-by-step explanation:
expand the brackets:
7x+28 + 6x-18 = 8x-24 - 2x-8
now, collect like terms:
13x + 10 = 6x -32 (subtract 6x from both sides)
7x + 10 = -32 (minus 10 from both sides)
7x = -42 (divide by 7)
x = -6

C) Victoria has y dollars. This amount is 12 times x, the amount of money in dollars Victoria’s brother has.
<u>Step-by-step explanation</u>:
The equation is represented as y = 12x
- The option A) does not match the equation. since it is given that x is 12 times y (x = 12y).
- The option B) does not match the equation since it is given that she recieves $12 as change (x = y-12)
- The option C) matches the equation since Victoria has 12 times the amount of his brother (y = 12x)
- The option D) does not match the equation since Victoria is 12 years greater (y = x+12)
Answer
B
Step-by-step explanation:
because it has to be less than according to the word problem and using common sense I know that if there are more than 1 of a number as an answer choice that means that it is most likely the answer
I'll assume that's


Please let me know if that's wrong.
These are two lines in point slope form. They'll meet at some x that makes the ys equal.





is the only solution.
Exactly one solution.
We really only had to ensure the lines had two different slopes. Then there's always exactly one solution.
If the lines had the same slope, they're either the same line (coincident) so an infinite number of solutions, all the points on that line, or they're parallel, no solutions.

Step by step solution
Summation of 1st diagonal =5+5
=10
Summation of 2nd diagonal =7+5
=12
Product of the diagonals
=10×12
=120
Area=1÷2×120
=60
