Answer:
English time + Math Time = 6 7/8 + 1 4/8 = 7 7/8+4/8 = 8 3/8
8 3/8 - Science time = difference = 8 3/8- 3 1/6 = 5 5/24
She spent 5 5/24 days more on her English and Math test than Science
Step-by-step explanation:
3x^4 becomes 3(3x)^4=3*3^4*x^4
y^2 becomes (3y)^2=3^2y²
the new z=3² the old z, so b is correct.
Answer: 0
Step-by-step explanation:
In this equation 0/y would equal 0, no matter what y is. 0/y means that there's 0 items out of y items (ex: substitute y with 2, it would be 0/2). Beginning with 1*0 (one times zero) the answer there would be 0. Since we already know that 0/y equals 0, the rest of the equation would be 0 - 0 which would equal to 0. Hope this explanation helps :)
These are the same line when you graph. So there are infinite solutions to this system.
10= -4 + x x=14 because you do the opposite of the sign you see in this case its a plus sign so you subtract -4 from ten and since the 4 is a negative and your subtracting you would add 4 I know this probably didn't help it sounds really confusing but I have hope that it did :)
