Keiko has a total of $5200
x is the amount of money in larger account
y is the amount of money in smaller account
x - y = $900
and x + y = $5200
<u>This creates two simultaneous equations:</u>
x - y = $900 ... (i)
x + y = $5200 ... (ii)
Adding (i) and (ii) :
2x = $6100 , x = $3050
y = x - $900 = $3050 - $900 = $2150
The amount of money in larger account (x) = $3050
The amount of money in smaller account (y) = $2150
Answer:
Step-by-step explanation:
first the parenthesis
3^4/3^0=3^4
anything raised to the power of 0 is 1
(3^4)^2=3^8 you multiply the powers
3^-6 * 3^8= 3^(-6+8)=3^2
Answer: 80 cubic feet
Step-by-step explanation:
Hello! Your question was not very clear, but I'm assuming you need to find the volume of the sandbox.
To find volume, you need to multiply height by width by length, which is h*l*w.
Height: 1 foot
Width: 8 feet
Length: 10 feet
V=8*10*1=80 cubic feet.
