I think it's 35. I was thinking like since 15×2=30 I said, 30+70=100 so 70÷2=35...

What is a 15 yard gain 
Alex_Xolod [135]
Are you by any chance referring to football? If you are, it is either a play in which by running or passing the offense moves down the field towards the opponent's endzone 15 yards, or it can be obtained by the defense committing an egregious penalty, such as a facemask, unsportsmanlike conduct, or unnecessary roughness.

X + y = -1<br> 4x - 2y = -16
djyliett [7]

Answer:

x=-3 \\and\\ y=2

Step-by-step explanation:

x + y = -1       Equation:1

4x - 2y = -16    Equation:2

Solving Equation:1

x+y=-1

Subtracting 'y' from both the sides:

x+y-y=-1-y\\\\x=-1-y

Putting 'x' in Equation :2

       4(-1-y)-2y=-16\\\\-4-4y-2y=-16\\\\-4-6y=-16

Adding '4' both the sides

          -6y=-16+4\\\\-6y=-12\\\\y=-12/-6\\\\y=2

Putting the value of 'y' in equation:1

           x+y=-1

           x+(2)=-1\\\\x=-1-2\\\\x=-3\\

The solution is:

          x=-3 \\and\\ y=2

Theo earns a base salary plus commission. At the end of September, he was paid $3,835.25 based on his monthly sales of $12,850.
hodyreva [135]

Theo's base salary  using a simultaneous equation approach is $2,996.22 .

In order to determine the base salary of Theo, we can express the two earnings and sales amounts using simultaneous equation, that we would solve to arrive at the base salary

Bear in mind that total earnings are determined as base salary plus commission

Let X be the base salary

Let R be the rate of commission

commission =sales*rate of commission

When earnings were $3,835.25 and sales is $12,850, we have the below equation:

X+(12,850*R)=3,835.25

X+12850R=3,835.25  .................... equation (1)

When earnings were $3,641 and sales is $9,875, we have the below equation:

X+(9,875*R)=3641

X+9875R=3641 .........................  equation (2)

subtract equation 2 from 1

2975R=194.25

R=194.25/2975

R=commission rate=6.52941176470588%

substitute for R in equation 1 to arrive at X(base salary)

X+(12850*6.52941176470588%)=3,835.25

X=3,835.25-(12850*6.52941176470588%)

X=base salary=$2,996.22
