Answer:
x=18
QR=29
RS=29
QS=29
Step-by-step explanation: 2X-7=5x-61=x+11 solve for x since all sides are equal
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
Answer:
y=mx+b
Step-by-step explanation:
Answer:
He missed 14 questions
Step-by-step explanation:
Total = Right + Miss ⇒ t = r + m
Right = Miss + 12 ⇒ r = m + 12
t = 40
Since t = r + m and r = m + 12 then:
t = m + 12 + m
t = 2m + 12
40 = 2m + 12
28 = 2m
m = 14
