Answer:

The expression is equal to 12.

Step-by-step explanation:

$-24-(18 / 6)*(-12)$

First of all, compute the parenthesis.

18 / 6 = 3

Now, replace 18/6 with 3 in our expression.

$-24-(18 / 6)*(-12)$

$-24-(3)*(-12)$

Next, compute the multiplication.

-12 * 3 = -36

Again, we'll replace that multiplication with negative 36:

$-24-(3)*(-12)$

$-24-(-36)$

Since subtracting a negative number is the same as adding a positive number:

$-24-(-36) = -24+36$

Compute the addition:

$-24+36=12$

$-24-(18 / 6)*(-12) = 12$

Answer: The expression is equal to 12.

The inside wheels of a car traveling on a circular path are rotating half as fast as the outside wheels. The front two wheels ar

barxatty [35]

Answer:

about 37.7 feet

Step-by-step explanation:

If the outside wheels are turning twice as fast, they go twice the distance in the same time. The distance they travel is proportional to the radius of the circle, so the outside circle must have twice the radius of the inside circle.

Adding 6 ft to the radius of the inside circle doubles the radius, so the inside circle's radius must be 6 feet. Then the circumference of the inside circle is ...

C = 2πr = 2π(6 ft) = 12π ft ≈ 37.7 ft

Solve x42=37 x 42 = 3 7 using two different strategies. Explain each strategy.

Dafna11 [192]

Given equation : $\frac{x}{42}=\frac{3}{7}$ .

Strategy 1: We can cross mutiply both sides remove fraction form.

On cross multiplication, we get

x * 7 = 3 * 42

7x = 126.

Dividing both sides by 7, we get

Strategy 2: We can find least common denominator(lcd) of both sides and multiplying both sides by that lcd to get rid denominators from both sides.

LCD of 42 and 7 is 42.

Therefore, multiplying both sides by 42, we get

$42\times \frac{x}{42}=42\times\frac{3}{7}$
