Answer:
-1
Step-by-step explanation:
It’s 101 because 72 and -29 have a difference of 101
Answer: The fact that beyblades spin at different speeds, you may want to get one that is fast while staying in control. Some have more mass than others leading them to spin slower, but the fact that they weigh so much may cause the other one to richochet off of it. Therefore get a big but fast beyblade that is very stable.
Answer: Hello there!
here we have two equations:
1) x + 3y = 7
2) 2x + 4y = 8
a) first we want to isolate x in the first equation:
x + 3y = 7
x = 7 -3y
done!
b) now we want to replace it in the second equation, and in this way get a equation that depends only on the variable y.
2x + 4y = 8
2(7 - 3y) + 4y = 8
c) now we sole this equation and obtain the value of y.
14 - 6y + 4y = 8
14 - 2y = 8
-2y = 8 - 14 = -6
y = 6/2 = 3
d) now we have the value of y, and we can substitute it on the equation that we got in the part a)
x = 7 - 3y
x = 7 - 3*3 = 7 - 9 = -2
e) now we knowt that x = -2 and y = 3, then the pair (x,y) can be written as:
(-2,3).
