Answer:B
Step-by-step explanation:
2/7(x−2)=4x
2/7x+−4/7=4x
2/7x+−4/7
−4x=4x−4x
−26/7x+−4/7=0
−26/7x+−4/7+4/7=0+4/7−26/7x=4/7
(7−26)*(−26/7x)=(7/−26)*(4/7)
x=−2/13
Answer:
47
Step-by-step explanation:
follow Pemdas order of operations.
8 + (9 + 23) − 9 + 8 × 6 ÷ 3 =
8 + (32) - 9 + 8 x 6 ÷ 3
8 + (32) - 9 + 16
add and subtract the rest and u get 47

Answer:
Step-by-step explanation:
Similar shapes must have corresponding sides in a constant proportion. Therefore, we can set up the following equation and solve for :
(divide corresponding sides)
Answer:
a) 0.15
b) 0.2
c) 0.6
Step-by-step explanation:
We are given the following in the question:
A: Stopping at first signal
B: Stopping at second signal
P(A) = 0.35
P(B) = 0.55
Probability that he must stop at at least one of the two signals is 0.75
a) P(at both signals)
0.15 is the probability that motorist stops at both signals.
b) P(at the first signal but not at the second one)
0.2 is the probability that motorist stops at the first signal but not at the second one.
c) P(at exactly one signal)
0.6 is the probability that the motorist stops at exactly one signal.
