Solve for the variable-6a+3=-3(2a-1)

Can some one help me. But explain in step by step?

Answers

Answer 1

Answer: Step 1: -6a + 3 = -3(2a - 1)
Step 2: -6a + 3 = -3(2a) + 3(1)
Step 3: -6a + 3 = -6a + 3
Step 4:+6a +6a
Step 5: 3 = 3

The quotient of the difference of a number and 24 divided 8 is the same as the number divided by 6

Answers

The number that satisfies the given condition is -72.

Let's break down the given statement step by step:

The difference of a number and 24:

Let's assume the number is represented by 'x'.

The difference of 'x' and 24 can be written as (x - 24).

Divided by 8: We divide the difference of 'x' and 24 by 8, which gives us ((x - 24) / 8).

The quotient of the difference of a number and 24 divided by 8: So, the quotient is ((x - 24) / 8).

The number divided by 6: We divide the number 'x' by 6, which gives us (x / 6).

The given statement says that the quotient obtained in step 3 is equal to the number divided by 6.

Mathematically, we can represent this as:

((x - 24) / 8) = (x / 6)

To solve this equation for 'x', we can cross-multiply:

6(x - 24) = 8x

Now, we can simplify and solve for 'x':

6x - 144 = 8x

Subtracting 6x from both sides:

-144 = 2x

Dividing by 2:

x = -72

Therefore, the number that satisfies the given condition is -72.

Myra asked Annabelle to buy her some perfume while she was in France. Annabelle paid 200 euros for it. Myra wants to pay Annabelle back in U.S. dollars. If the foreign exchange rate between the U.S. dollar and the euro is 1:0.7, how much should Myra pay Annabelle?A.) $140
B.) $240
C.) 286

Answers

Answer:

286

Step-by-step explanation:

Given : Myra asked Annabelle to buy her some perfume while she was in France. Annabelle paid 200 euros for it. Myra wants to pay Annabelle back in U.S. dollars.

To Find: If the foreign exchange rate between the U.S. dollar and the euro is 1:0.7, how much should Myra pay Annabelle?

Solution:

Since Annabelle paid 200 euros

And Myra wants to pay Annabelle back in U.S. dollars.

Let Myra paid amount to Annabelle in U.S. dollar be x

We are also given that the U.S. dollar and the euro is 1:0.7

⇒ $(1)/(0.7)=(x)/(200)$

⇒ $(1*200)/(0.7)=x$

⇒ $(200)/(0.7)=x$

⇒ $285.7=x$

⇒285.7≈286

Thus Myra should pay $286 to Annabelle

Answer:

$286
