The ratio of money in Terry's bank account to Faye's bank account was 3:5.Terry then put £220 in his account and Faye withdrew £300 from her account.
They now had the same amount in their accounts.
How much did they initially have altogether?

Answers

Answer:

£780 and £1300

Step-by-step explanation:

The ratio in their accounts is 3 : 5 = 3x : 5x ( x is a multiplier )

Terry put £220 into his account, then 3x + 220

Faye withdrew £300 from her account then 5x - 300

They now have the same amounts in their accounts, thus

5x - 300 = 3x + 220 ( subtract 3x from both sides )

2x - 300 = 220 ( add 300 to both sides )

2x = 520 ( divide both sides by 2 )

x = 260

Thus initial amount in their accounts

3 × £260 = £780 ← Terry's account

5 × £260 = £1300 ← Faye's account

2 3 4 cups of oatmeal and makes one dozen muffins. If he makes 3 dozen muffins for a club meeting and 2 1 2 dozen muffins for a family reunion, how much oatmeal will he use?

Answers

Answer:

15 1/8 cups of oatmeal will be used

Step-by-step explanation:

Firstly, we shall be calculating the total number of dozens of muffin made

That would be the addition of the dozens of muffin made for the family reunion and that made for the club meeting = 3 + 2 1/2 = 5 1/2 or simply 5.5 dozens

Now, from the question initially, 2 3/4 or simply 2.75 cups of oatmeal makes 1 dozen muffins

x cups of oatmeal = 5.5 dozens of muffin

x * 1 = 2.75 * 5.5

x = 15.125 cups of oatmeal or simply 15 1/8 cups of oatmeal

4 = 2/3(x-18) solve for x

Answers

Answer:

x=24

Step-by-step explanation:

Given:

$\sf 4 = (2)/(3)(x-18)$

To find:

Value if x.

Solution:

In order to isolate x or solve x, we need to get rid of the fraction on the right side of the equation.

Multiplying both sides of the equation by 3, the denominator of the fraction.

$\sf 4 * 3 = (2)/(3)(x-18) * 3$

Simplifying both sides, we get:

$\sf 12 = 2(x-18)$

Dividing both sides of the equation by 2 to get x by itself.

$\sf (12)/(2) = (2(x-18))/(2)$

Simplifying both sides, we get:

$\sf 6 = x-18$

Add 18 to both sides of the equation

$\sf 6 + 18 = x-18 + 18$

Simplifying both sides, we get:

$\sf 24 = x$

Therefore, the value of x is 24.

Answer:

x = 24

Step-by-step explanation:

4 = (2/3)(x - 18)

To isolate x, we'll follow these steps:

Multiply both sides of the equation by 3 to get rid of the fraction:

3 * 4 = 2(x - 18) 12 = 2x - 36

Add 36 to both sides of the equation:

12 + 36 = 2x 48 = 2x

Finally, divide both sides by 2:

x = 48 / 2 x = 24

So your answer should be. x = 24

A polynomial function has a root of –6 with multiplicity 1, a root of –2 with multiplicity 3, a root of 0 with multiplicity 2, and a root of 4 with multiplicity 3. If the function has a positive leading coefficient and is of odd degree, which statement about the graph is true?A.) The graph of the function is positive on (–6, –2).
B.) The graph of the function is negative on (negative infinity symbol, 0).
C.) The graph of the function is positive on (–2, 4).
D.) The graph of the function is negative on (4, infinity symbol).

Answers

The correct answer for the question that is being presented above is this one: "C.) The graph of the function is positive on (–2, 4)." A polynomial function has a root of –6 with multiplicity 1, a root of –2 with multiplicity 3, a root of 0 with multiplicity 2, and a root of 4 with multiplicity 3. If the function has a positive leading coefficient and is of odd degree, then C.) The graph of the function is positive on (–2, 4).
