Answer:

x = -7/2

y = -13/2

Step-by-step explanation:

Solve for y in the first equation.

y = 4 + 3x

Put y as 4 + 3x in the second equation and solve for x.

-9x + 5(4 + 3x) = -1

-9x + 20 + 15x = -1

6x + 20 = -1

6x = -21

x = -21/6

x = -7/2

Put x as -7/2 in the first equation and solve for y.

y = 4 + 3x

y = 4 + 3(-7/2)

y = 4 + -21/2

y = -13/2

John said he can find 38×10 by adding a 0 to the end of 38 to get 380. John finds 46.52×10 using the same method and gets 46.520
cestrela7 [59]

Answer: See explanation

Step-by-step explanation:

John said he can find 38×10 by adding a 0 to the end of 38 to get 380. John finds 46.52×10 using the same method and gets 46.520.

For the first one that is, 38 × 10 = 380, John is correct. For the second one, that is, 46.52 × 10 = 46.520. John is incorrect. In this case, the first one is correct because John was multiplying by a whole number.

For the second one involving a decimal, John could have shifted the decimal point one place to the right and not add 0 to the end. Then he will get:

46.52 × 10 = 465.2

So the answer comes out to be 30 marbles in the bag
