Chase was trying to solve for x and y. He knows that the value of x is 3 times the value of y and that half of x plus twice y is equivalent to −14. Which system of equations could he use to solve for x and y?
A
3y=x12x+2y=−14

B
3x=y12y+2x=−14

C
3y+x=−1412x=2y

D
3x+y=−1412y=2x

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
