Answer: Choice B and D are both correct.

Step-by-step explanation:

The expression has two adjacent negative signs in the middle. The two negative signs are to be multiplied, which then produces one positive sign.

Choice B is therefore correct because the expression becomes 6+6 which is 6 to the right of the number line where the numbers are increasing.

Choice D is also equally correct because the addition of 6 to 6 equals 12(6+6 = 12).

Divide 1000 by 8 which would give you 125. So they have 125 cans and they need to collect 8 times as many, meaning 8 times of what they have which is 125. And 125 times 8 is equal to 1000. YOU'RE WELCOME :D

Eight hot dogs and seven hot dog rolls cost $\$13.60$. Seven hot dogs and eight hot dog rolls cost $\$13.40$. How much, in dolla
Maru [420]

Answer:

$1.80

Step-by-step explanation:

Let the cost of a hot dog = x

The cost of a hot dog roll = y

Eight hot dogs and seven hot dog rolls cost $\$13.60$.

8x + 7x = $13.60..... Equation 1

Seven hot dogs and eight hot dog rolls cost $\$13.40$.

7x + 8x = $13.40...... Equation 2

Combining both Equation

8x + 7x = $13.60..... Equation 1

7x + 8x = $13.40...... Equation 2

Eliminating x

Multiply 1 by 7

Multiply 2 by 8

56x + 49y = 95.2..... Equation 3

56x + 64y = 107.2 ..... Equation 4

Subtracting 4 from 3

-15y = -12

y = -12/-15

y = 0.8

Cost of one hot dog roll = $0.8

Solving for x

8x + 7x = $13.60

8x + 7(0.8) = 13.60

8x + 5.6 = 13.60

8x = 13.60 - 5.60

8x = 8.0

x = 8.0/8

x = 1.

Cost of one hot dog = $1.0

The cost in dollars of a hot dog and a hot dog roll cost combined is

x + y

= $1 + $0.8

= $1.80
