Answer:
Steve's lunch is $8.00
Step-by-step explanation:
First you have to make a formula for this almost.
s= Steve's lunch
y= your lunch
s= y-3
s+y-19
then plug in s
y-3+y=19
Then simplify 2y-3=19
Add the three to both sides 2y=22
Divide both sides by 2 y=11
Last plug y into one of your formulas
s=Y-3
s=11-3
s=8
BE SURE TO CHECK YOUR ANSWER S+Y=19 11+8=19 :)
2^-1(5)^3(7)^4/2^6(5)^-3(7)^3= (5)^6(7)/2^7
A perfect square is defined as the product of two equal whole numbers.
For example;
5 x 5 = 25, 25 is a perfect square.
5 has the factors of 1&5 and no self-multiplied factors, so it is NOT a perfect square.
8 has the factors of 1&8 and 2&4, and has no self-multiplied factors so it is NOT a perfect square.
36 has the factors of 1&36, 2&18, 3&12, 4&9, and 6&6.
36 has 6•6, which is a perfect square.
Although there could be more than two numbers that the question's asking for, 44 (simply put) is not a perfect square.
36 is your answer.
I hope this helps!
