<span>We'll make $10 x and the $20 y.
x + y = 7,200
10x + 20y = 113000
10x + 10y = 72000
10x + 20y = 113000
10y = 41,000
y = 4,100
Substitute y = 4,100
x + y = 7,200
x + 4,100 = 7,200
x = 7,200 - 4,100
x = 3,100
3,100 x $10 tickets
4,100 x $20 tickets</span>
Answer:
x=-2
Step-by-step explanation:
(2/3)^x-1=27/8
Rewriting the right hand side
(2/3)^x-1=(3/2)^3
We know that a^-b = 1/a^b Hint: { 1/(3/2) = 2/3}
(2/3)^x-1=(2/3) ^-3
The bases are the same, so the exponents are the same
x-1 = -3
x -1+1 = -3+1
x = -2
- <em>combined mass in scientific notation can be written as</em> 97.2× kg
- Scientific notation can be regarded as a way of writing very large as well as very small numbers.
Mars of mass= (6.42x kg )
Mercury= (3.3x kilograms)
Then we add together
(6.42x )+ (3.3x) kilograms.
= 9.45 × kilograms
Therefore, combined mass in scientific notation can be written as 97.2× kg

<span>So we wan't to know what is the selling price of a motorcycle if the starting price was 2499$ and the discount was 249$. To get the selling price we need to subtract the discount from the starting price: 2499$-249$ = 2250$. So the selling price is 2250$.</span>
