-2x + 5y = 8
2x + 2y = 6
----------------add
7y = 14
y = 14/7
y = 2
2x + 2y = 6
2x + 2(2) = 6
2x + 4 = 6
2x = 6 - 4
2x = 2
x = 2/2
x = 1
solution is (1,2)
Answer:
it has a volume of 1 cubic unit. its called a "unit block"
Step-by-step explanation:
Answer:
X = 7
Step-by-step explanation:
because of you do 5+2 = 7 then you minus 3 which you get 4.
the. if you have a production of around 10 you will get 7.
or you can do.
3+2 which is 5 and then you multiply that by 2 which is 10 and then you comprised that number therefore you will get 6 but you have to find X so we youndelie (think that's how u spell it) X which will equal to 1 and 6+1 is 7. once you get it it's quite simple
X^2-4 = x^2 - 2^2
= (x+2)(x-2)
