PLS HELP I ONLY HAVE 20 MINUTES
Step-by-step explanation:
4x + 2y = 10 --------(1)
2x + 3y = 33 -----------(2)
Multiply 2 with eq. (1) and 4 with eq. (2)
8x + 4y = 20 ____________(3)
8x + 12y = 132 ______(4)
Subtracting (3) from (4),
8x + 4y = 20
- 8x -12y = -132
----------------------
0 -8y = -112
y = 112/8
y = 4 is the answer.
Putting the vakue of y in eq. (2),
2x + 12 = 33
2x = 33-12
2x = 21
x = 21/2 is the answer.

Answer:
C 1/3
Step-by-step explanation:
The numbers on a 6-sides die are 1, 2, 3, 4, 5, 6.
The number of an 8-sided die are 1, 2, 3, 4, 5, 6, 7, 8.
All the possible sums are:
2, 3, 4, 5, 6, 7, 8, 9,
3, 4, 5, 6, 7, 8, 9, 10,
4, 5, 6, 7, 8, 9, 10, 11,

The multiples of 3 are shown in bold and italic.
There are 48 possible sums.
16 sums are multiples of 3.
p(numbers whose sum is a multiple of 3) =
(number of outcomes that are multiples of 3)/(total number of possible outcomes)
p(numbers whose sum is a multiple of 3) = 16/48
p(numbers whose sum is a multiple of 3) = 1/3

A store down the street is selling a console 50% of from 236.87 if i were to buy the console wit my 490.45 how much money will i get back?
Answer:
$372.01
Step-by-step explanation:
50% of $236.87 is half of it, which means the console is being sold for $118.44 because:
235.87/2 = 118.435
Round this to the nearest cent:
$118.44
If you have $490.45, and you spend $118.44, it means that you subtract the cost from your own money:
490.45 - 118.44 = 372.01
You will have $372.01 left.

If cell phone plan costs $0.20 cents per minute. Lisa has budgeted $35 a month for her cell phone then 175 minutes Lisa can use each month
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that A cell phone plan costs $0.20 cents per minute.
Lisa has budgeted $35 a month for her cell phone.
We need to find how many minutes Lisa can use each month.
Let us form a proportional equation to find this.
Let x be the number of minutes Lisa can use each month.
0.20/1=35/x
Apply cross multiplication
x=35/0.2
x=175
Hence, 175 minutes Lisa can use each month.

What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
You need to convert from mixed number to decimal number. To do this you can follow the steps shown below:
Step 1: You must divide the numerator of the fraction by the denominator of the fraction.
Step 2: Now you must add the quotient obtained to the Whole number part.
So, you get:
3 + 1/4
=3 + 0.25
= 3.25
Then, the scale image that maps "Figure a" onto "Figure b" is:
1: 3.25
Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure a" by .
Therefore, you get that the result is:
x = 3 * 3.25
or, x = 9.75
Hence, The solution is : the value of x is x = 9.75.
