Answer:
30
Step-by-step explanation:
1. x + 40 = 3x - 20
2. 40 = 2x - 20
3. 60 = 2x

Suppose a mango cost x dollar and a apple cost y dollar
there will be an binary system of equation
8*x+3*y=18
3*x+5*y=14.5
so soultions have to x=48/31 y=16/31
Answer: 6
Step-by-step explanation:
Let's start by getting the equation to slope intercept form
First simplify
Then get y by itself
In slope intercept form y=mx+b, m is the slope
In this case the slope is 6
No, it is not a perfect cube. A perfect cube is a number that is obtained when you cube an integer. For example, 8 (cube of 2), 27 (cube of 3) and 64 (cube of 4). Since -3 cannot be obtained by cubing an integer, it is not a perfect cube.
22+2/2=23
22 is whole number
one plus sign
and 2/2 is the fraction
4 digits are 2
