Answer:
the answer is c:
5x-2y=1
2x+y=4
Answer:
(1,1)
Step-by-step explanation:
5x-2y=1
2x+y=4
Im gonna use substitution but you could also use elimination
2x+y=4
-2x -2x
y=-2x+4
replace y in the first equation with the second equation
5x-2(-2x+4)=1
distribute -2
5x+4x-8=1
add
9x-8=1
+8 +8
9x=9
divide both sides by 9
x=1
then put x in for the equation fo your choice im gonna use the second one
2(1)+y=4
2+y=4
-2 -2
y=1
Hope this helps :))

Yes, the decimal form of is indeed a repeating decimal. The expression is equivalent to , which is also 1.3333333 or "1.3 bar", signifying that the 3 will repeat infinitely.
Either using a calculator or long division, we can show that 4/3 = 1.333333...
Because this string of 3's goes on infinitely, 4/3 is indeed a repeating decimal.
Marianne purchases 16 bags of potting soil, which weighs 5/8 pounds per bag.
a) Marianne buys 10 pounds of potting soil.
b) She need 5 additional bags.
A fraction's numerator is the term that appears above the vinculum. It illustrates how many parts we have in total. A fraction's denominator is the term that appears below the vinculum. It reveals how many parts there are in all of us. A fraction's denominator and numerator are its top and bottom respective numbers.
The two numbers, which are separated by a line, are referred to as the numerator and the denominator, respectively. The line simply divides the numerator from the denominator and can be horizontal or slanted to mean either.
Given:
Marianne buys 16 bags of potting soil that comes in 5/8 pound bags.
a) 16 × 5 / 8 = 80 / 8 = 10
Marianne buys 10 pounds of potting soil.
b) She has 10 pounds, so she need bags only for 3 ponds.
3 : 5 / 8 = 3 × 8 / 5 = 24 / 5 = 4.8
She need 5 additional bags.
The complete question is:
Marianne buys 16 bags of potting soil that comes in 5/8 pound bags.
a) How many pounds of potting soil does Marianne buy?
b) If Marianne's father calls and says he needs 13 pounds of potting soil, how many additional bags should she buy?
