Answer:

7. 8200 miles

8. $350

Step-by-step explanation:

7. The first trip nets 3400 miles; the next four trips (for a total of five) net 1200 miles each, so the total for 5 round trips is ...

... 3400 + 4×1200 = 8200 . . .  miles

8. The first month costs $100; the next 5 months (for a total of 6) cost $50 each, so the total for 6 months is ...

... $100 + 5×$50 = $350

Which equation is true? I. (32 ÷ 8 – 2)6 = (32 – 1)2 II. 72 ÷ 9·4 = 62 ÷ (6 + 3) II only Neither I nor II I only I and II
Umnica [9.8K]

Answer: The answer is (b) Neither I nor II.


Step-by-step explanation: We are given two equations and we need to find which is true. Since it is a simple algebraic question, so we just need to follow BODMAS rule to check the equations.

The equations are as follows -  

(I)~~L.H.S=(\dfrac{32}{8}-2)6=(4-2)6=2\times 6=12.

R.H.S=(32-1)2=31\times 2=62.

Since L.H.S ≠ R.H.S, so this equation is not correct.

(II)~~L.H.S=\dfrac{72}{9\times 4}=2.

R.H.S=\dfrac{62}{6+3}=\dfrac{62}{9}.

Since L.H.S ≠ R.H.S, so this equation is also not correct.

Thus, the correct option is (b) Neither I nor II.

rusak2 [61]
Answer: 6x=42

Explanation: After the step 6x+6=36, it’ll equal 6x=30 because when you subtract the 6 on both sides, it’ll equal 30, revealing it’s actually 6x=30, with the conclusion of x=5.

galina1969 [7]

Answer:

9/40

Step-by-step explanation:

To find the price per can, we take the cost and divide by the number of cans

$5.40/24

5.4/24

Since there is a decimal in the numerator, multiply the top and bottom by 10

5.4/24 * 10/10

54/240

Divide the top and bottom by 6

9/40
