What is the answer

yan [13]

$2.408 \times {10}^{24} \: \div \: 6.02 \times {10}^{23} = \\$

$\frac{2.408 \times 10 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{24.08 \times {10}^{23} }{6.02 \times {10}^{23} } =4 \\$

So the answer is 4

Yani buys a certain brand of cereal that costs $10 per box. Yani changes to a super-saving brand of the same size. The equation

makkiz [27]

Answer:

A) Original price : y =10.x

Cheaper brand : y = 7x

The original box is $3 more than the cheap one.

Proof: Suppose 1 box is bought of each (x=1),Original will cost $10 & the Cheaper Price is $7

B) Each time he buys a cheap brand he save $3 ($10-$7).

On 5 cheap boxes, He would save $3 x 5 boxes = $15.

Step-by-step explanation:

Part A: The price of the first cereal that Yani bought was $10 and he new cereal is $7.

$10 - $7 = $3. The original box of cereal was $3 more than the super- saving cereal.

Part B: Yani will save $15 each month.

With the $10 cereal he used to pay $50 per month. Now with the super-saving cereal, he will now pay $35 per month.

So we need to subtract $50 - $35 = $15

-10x - 19 = 19 - 8x <br> help plzzzzz

Licemer1 [7]

$Combine like terms: -10x + 8x = -2x
-19 + -2x = 19 + -8x + 8x

Combine like terms: -8x + 8x = 0
-19 + -2x = 19 + 0
-19 + -2x = 19

Add '19' to each side of the equation.
-19 + 19 + -2x = 19 + 19

Combine like terms: -19 + 19 = 0
0 + -2x = 19 + 19
-2x = 19 + 19

$ $Simplifying
-10x + -19 = 19 + -8x

Reorder the terms:
-19 + -10x = 19 + -8x

Solving
-19 + -10x = 19 + -8x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8x' to each side of the equation.
-19 + -10x + 8x = 19 + -8x + 8x$

$Combine like terms: 19 + 19 = 38
-2x = 38

Divide each side by '-2'.
x = -19

Simplifying
x = -19$
