There is a total of 30 erasers
X=(180-50-55)
x=75°
............
the correct answer is A) 10x + 30
Answer:2
just make them into positive if there’s 2 negatives 7-5=2
Y = x + 1.75...so we sub in x + 1.75 for y in the other equation
4x - 2y = 4
4x - 2(x + 1.75) = 4....distribute thru the parenthesis
4x - 2x - 3.5 = 4....add 3.5 to both sides
4x - 2x = 4 + 3.5...simplify
2x = 7.5....divide both sides by 2
x = 7.5 / 2
x = 3.75
now we sub in 3.75 for x in either of the original equations to find y.
y = x + 1.75
y = 3.75 + 1.75
y = 5.5
so ur solution is : (3.75,5.5) <==
