Answer:
3.5x10³
Step-by-step explanation:
7x10^5=700000
2x10^2=200
Divide both by 100
7000÷2=3500
divide by 1000 as standard form is less than 10
1000 is 10 cubed
3500÷1000 is 3.5
∴3.5x10^3 is answer
Answer:
$8
Step-by-step explanation:
If 5 prizes cost 80 cents that means that 1 prize costs 16 cents because 80 divided by 5 = 16. And to get the cost of 50 prizes you do 16(50) = 800 cents. There are 100 cents in a dollar, giving you $8
Answer:
no
Step-by-step explanation:
let x=12 and y=25 and substitute:
does 25 = 2(12)+2?
no, 25 ≠ 26
First we must define variables:
x: number of Snickers candy bars
y: number of KitKat bars
We write the system of equations:
27.50x + 21.50y = 119.50
48x + 36y = 204
Solving the system we have:
x = 2 packages
y = 3 packages
Answer:
she did buy:
2 packages of Snickers candy bars
3 packages of KitKat bars
