How do I solve 4(x+3)=-6(4y-2)

Mathematics
1 answer:
True [87]2 years ago
4 0
<h2>Answer:</h2><h2>x=-6y</h2>

Step-by-step explanation:

Divide both sides by 4:

\frac{4\left(x+3\right)}{4}=\frac{-6\left(4y-2\right)}{4}

Simplify to give:

x+3 = -3(2y-1)

Subtract 3 from both sides:

x+3-3 = -3(2y-1)-3

Simplify to give your answer:

x=-6y

Jake is buying a sweater with the price of 30 dollars the store is having a sell that will reduce the price by 30%. Sales tax of
shusha [124]

Answer:Jake's total cost is $22.05

Step-by-step explanation:

The initial price of the sweater is $30. The store is having a sell that will reduce the price by 30%. This means that there is a reduction in the original amount of the sweater by 30% which is expressed as

30/100 × 30 = $9

The new price of the sweater would be 30 - 9 = $21

Since a sales tax of 5% will be added to the final purchase price, the value of the tax would be

5/100 × 21 = 0.05×21 = $1.05

Jake's total cost would be

21 + 1.05 = $22.05

Solve using square roots 3x^2+25=73
seropon [69]
Heya !

Given expression -

3 {x}^{2} + 25 = 73

Subtracting 25 both sides ,

3 {x}^{2} + 25 - 25 = 73 - 25 \\ \\ 3 {x}^{2} = 48

Dividing by 3 on both sides ,

\frac{3 {x}^{2} }{3} = \frac{48}{3} \\ \\ {x}^{2} = 16

Therefore ,
x = + \: 4 \: \: \: \: or \: \: - 4 \: \: \: \: \: \: \: Ans.

How many different arrangements can be made with the letter of the word 'M O R O C C O'?
valentinak56 [21]
Since the order matters, it's a permutation of 7 letters, but mind you in 
MOROCCO. you have 3 O's and 2 C's, Hence the arrangements are:

⁷P₇ /(3!2!) = 7!/(3!2!) = 5040/(3!2!) = 420 arrangements
