Solve the following systems of equations below 1.y=x+7, y=-1/2x+4
2.y=-1/5x-3,y=x+3
3. y=-1/2x+3,3x-2y=10
4. y=-x+5,2x-y=7
Determine if the following has no solutions, infinitely many solutions, or exactly one solution below.
1.6x+y=-5,30x+5y=-20
2. x+y=5, -5x-4y=-18
3. x+y=3, -x-y=-3

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

95.03 is the answer. hope this !
