X2=4(5-1)
x2=4(4)
x2=16
x=4
Check: 4 squared (4 times 4) equals 16. When you square a number, you multiply the number by itself.
Answer:
6 red marbles
Step-by-step explanation:
We must first find our multiplier since a sample represents a population (the whole thing).
6/2 = 3, so 3 * 2 = 6.
I will use the value of 6/2, aka 3 and use that as my divisor.
18/3 = 6.
Therefore, you would expect to have 6 red marbles.
ab + ac + ad is the same as a(b + c + d) according to the distributive property
4280 because 75+5+4200= 4280
20 * .10 = 2 <em>(2 = 10% of 20)</em>
20 + 2 = 22
20 x .07 = 1.4 <em>(1.4 = 7% of 20)</em>
20 + 1.4 = 21.4
The price of a 20$ haircut with a 10% tax would be $22.
The price of a 20$ haircut with a 7% tax would be $21.40.
