Answer:

x = - 3

Step-by-step explanation:

Given the 2 equations

y = $\frac{1}{3}$ x + 7 → (1)

y = 3x + 15 → (2)

Since both equations express y in terms of x, equate the right sides

3x + 15 = $\frac{1}{3}$ x + 7

Subtract $\frac{1}{3}$ x from both sides

$\frac{8}{3}$ x + 15 = 7 ( subtract 15 from both sides )

$\frac{8}{3}$ x = - 8 ( multiply both sides by 3 )

8x = - 24 ( divide both sides by 8 )

x = - 3

Answer:

Rewrite the expression 10(15 – 6) using the distributive property of subtraction.

A) 10(6) – 10(15)

B) 10(9)

C) 10(6 –15)

D) 10(15) – 10(6)

Show/Hide Answer

A) 10(6) – 10(15)

Incorrect. Here a greater number would be subtracted from a lesser number, and the answer would not be a whole number. The correct answer is 10(15) – 10(6).

B) 10(9)

Incorrect. The numbers in parentheses were subtracted before the number 10 could be distributed. The correct answer is 10(15) – 10(6).

C) 10(6 –15)

Incorrect. You probably used the commutative law instead of the distributive property. The correct answer is 10(15) – 10(6).

D) 10(15) – 10(6)

Correct. The 10 is correctly distributed so that it is used to multiply the 15 and the 6 separately.

Step-by-step explanation:

$2 \times 3 \times 4 \times 5 \times 6 \times 7 \times 9 \times 10 \times 20 \times 31 \times 41 \times 42 \\ 6 \times 20 \times 42 \times 90 \times 620 \times 1722 \\ 120 \times 3780 \times 1,067,640 \\ 453,600 \times 1067640 \\ = 4.84281504 \times {10}^{11}$
