Step-by-step explanation:
7.75 x 840 = 6510
Answer:
z = 21 ; y= 16
Step-by-step explanation:
first of all we have to isolate a variable.
In second expression we can obtain:
3y = 2z+6
y = 2/3 z + 2
now we have to substitute this value in the first equation and solve it
8(2/3z+2)-5z = 23
16/3z + 16 -5z = 23
16z +48 - 15z = 69
z = 21
now we have to substitute z in the second equation:
y = 2/3 (21) +2
y = 14+ 2 = 16
y = 16
If a^2+b^2=c^2, and you just substitute the numbers in for a and b, for ex: 14 for a and 48 for b, you get 50 for c... So the first one haha
