Equation 1: x + y = 40 ; therefore y = 40 - x
Equation 2: 25x + 15y = 900
Find x first:
25x + 15 (40 - x) = 900
25x + 600 - 15x = 900
10x = 900 - 600
x = 300÷10
x = 30 hours Chris needs to spend for tutoring job
y = 40 - 30
y = 10 hours Chris needs to spend for referencing job
Answer:
(-3/2 or 1.5, 3/2 or 1.5)
x = -3/2 or -1.5
y = 3/2 or 1.5
Step-by-step explanation:
the midpoint formula is x1+x2/2 and then y1+y2/2 so -4 +1 = -3/2 for x. for y, 9 + -6 = 3/2. so the midpoint would be (-3/2 or 1.5, 3/2 or 1.5) depending on if you’re using decimals or fractions
The answer to this question is :
2 1/2
Answer:
m<CGE: 86
Step-by-step explanation:
<CGE:
64 + 30 + x = 180
94 + x = 180
x = 86
In short, the set formed by the negative integers, the number zero and the positive integers (or natural numbers) is called the set of integers. Integer is also known as a whole number.
