Answer:
2.7
Step-by-step explanation:
that is correct....
30b + 100u = 900
5b + 25u = 200....multiply by -6
------------------
30b + 100u = 900
-30b - 150u = - 1200 (result of multiplying by -6)
------------------add
-50u = - 300
u = 6 <== upgrated phones sold
30b + 100u = 900
30b + 100(6) = 900
30b + 600 = 900
30b = 900 - 600
30b = 300
b = 10 <== basic phones sold

A
Step-by-step explanation:
48 divided by 6 = 8. 6 times 8 = 48, so x = 8
X= (85+92+88+98)/4
The slash means to divide. So you’re making a fraction with all the scores on top and the number of scores on the bottom.
