Add and divide by 2 remembering the key 543+539= 546
Answer:
x = 6
Step-by-step explanation:
(2×/×+3)- (×/×-3)=(3÷3-×)
2x/x+3-x/x+3= 1-x
2 + 3 - 1 + 3 - 1 = x
8-2 = x
x = 6
Z^2 -3z -18
Factors of 18 that subtract to get-3: -6 and 3
(z - 6)(z + 3)
Since 1*7=7, 1 4/7= (7+4)/7=11/7. When dividing fractions, we switch the numerator and denominator for the bottom number, so in this case we'd have
(11/7)*(6/5)=66/35=around 1.89
