Answer:
x = 25 units
Step-by-step explanation:
here's the solution: -
the given triangles are similar, so their sides are proportional,
that's why ,
=》
=》
=》

hence, the value of x = 25 units
59 is the answer because I said so
Find an explicit formula for the arithmetic sequence -45,-30,-15,0,...−45,−30,−15,0,...minus, 45, comma, minus, 30, comma, minus
juin [17]
Answer:
= 15n - 60
Step-by-step explanation:
The n th term ( explicit formula ) of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 45 and d = - 30 - (- 45) = - 30 + 45 = 15, thus
= - 45 + 15(n - 1) = - 45 + 15n - 15 = 15n - 60
The probability that a U.S. household selected at random has a computer and has Internet access will be 0.72. The C and I are independent events. Then the correct option is B.
<h3>What is probability?</h3>
Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
Approximately 80% of households in the United States have computers. Of those 80%, 90% have Internet access.
Then the probability that a U.S. household selected at random has a computer and has Internet access will be
P(C and I) = 0.80 × 0.90
P(C and I) = 0.72
Then the C and I are independent events.
Then the correct option is B.

Answer:
Step-by-step explanation:
6x=1/2(2x +7) Multiply both sides by 2
2*6x = 1/2(2x + 7)*2
12x = 2x + 7 Subtract 2x from sides
12x-2x =2x-2x+7
10x = 7 Divide by 10
x = 7/10
x = 0.7
Let's check it
6(0.7) = 4.2
1/2 (2*0.7 + 7)
1/2 (1.4 + 7)
1/2 ( 8.4)
4.2
Both sides check. The answer must be x = 0.7
