Answer:
The expression is (---- + 2x)³
Step-by-step explanation:
To represents a verbal expression as an algebraic expression, we must use mathematics symbol and variables (name the unknowns quantity by letters)
The verbal expression is:
<em>Cube of more than two times a number</em>
→ Give a name for the number, assume that it is x
→ More than means (+)
→ Two times means multiply the number by 2 (x × 2)
→ The cube means power 3 for (---- more than 2x)
∴ The expression is (---- + 2x)³
<em>If the missing is 5, the statement will be The cube of 5 more than two times a number.</em>
∴ The expression is (5 + 2x)³
→ You can choose any number of the missing part
Answer:
8 one-dollar bills
3 five-dollar bills
2 ten-dollar bills
Step-by-step explanation:
Let x = # of one-dollar bills, y = # of five-dollar bills, and z = # of ten-dollar bills. Total amount in the wallet is $43, so the first equation would be 1x + 5y + 10z = 43. Next, there are 4 times as many one-dollar bills as ten-dollar bills, so x = 4z. There are 13 bills in total, so x + y + z = 13
x + 5y + 10z = 43
x = 4z
x + y + z = 13
x + 5y + 10z = 43
x + 0y - 4z = 0
x + y + z = 13
5y + 14z = 43
-y - 5z = -13
5y + 14z = 43
-5y - 25z = -65
-11z = -22
z = 2
x = 4z
x = 4*2 = 8
x + y + z = 13
8 + y + 2 = 13
10 + y = 13
y = 3
