Answer:

a = -2

Step-by-step explanation:

  1. Combine like terms: 7a + a = 8a
  2. Re-write the expression: -11 = 5 + 8a
  3. Subtract 5 from each side, so it now looks like this: -16 = 8a
  4. Divide each side by 8 to cancel out the 8 next to a. It should now look like this: -2 = a

I hope this helps!

Rewriting the whole as an Equivalent Fraction

3.1 Subtracting a fraction from a whole

Rewrite the whole as a fraction using x2 as the denominator :

2x2 - 5x = ———————— = ———————————————

1 x2

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

What is the difference between the smallest six-digit whole number and the greatest 4-digit number
spin [16.1K]
What's the smallest six-digit whole number possible?
It is 100000

try counting, six digits, right? if you even take 1 off from it, it's no longer six digits, so it is the smallest six-digit whole number possible.

what's the greatest 4-digit number?
It should be 9999
try adding 1 to it, it becomes five-digit number.

So, 9999 is the greatest 4-digit whole number possible.

To get a difference, subtraction.
100000 - 9999 = 90001


Just as a tip, for six digit number, 000000 does not work, as it is same as 0

nikitadnepr [17]

Answer:

The equation needed is

\frac{3}{4}p=423

p=564\ friends

Step-by-step explanation:

<u><em>The correct question is</em></u>

Clancy has 423 cups of yogurt to share with his friends at a party. Each guest will receive 1 serving of yogurt which is 3/4 of a cup. Write a multiplication equation to determine the number of people, p, who can be invited to the party

we know that

Each guest will receive 3/4 of a cup of yogurt

so

using proportion

Find out the number of people, who can be invited to the party, if Clancy has 423 cups of yogurt to share with his friends

Let

p -----> the number of people

\frac{1}{(3/4)} =\frac{p}{423}

\frac{3}{4}p=423 -----> equation needed

p=\frac{423}{(3/4)}

p=\frac{423*4}{3}

p=\frac{1,692}{3}

p=564\ friends
