Mathematics
1 answer:
-Dominant- [34]3 years ago
3 0

Answer:

x = -7

Step-by-step explanation:

All triangle angles add up to 180

84 + x + 59 + x + 51 = 180

2x + 194 = 180

2x = 180 - 194

2x = -14

x = -7

Translate the phrase into an algebraic expression.
adell [148]

Answer:

8 + \frac{5}{w}

Step-by-step explanation:

From the phrase, the <em>answer</em> is smaller(less) by 8  when compared(equal (=)) to quotient of 5 and w ...

So:

Answer - 8 = quotient of 5 and w

Here, quotient is the whole number from a <em>division</em>. The division here is \frac{5}{w}

Therefore,

Answer - 8 = \frac{5}{w}

Answer = 8 + \frac{5}{w}

Hence the phrase into algebraic expression is 8 + \frac{5}{w}

Find the first term, a1, of an arithmetic sequence if a12 = 38 and a45 = 170.
snow_lady [41]
Standard formula for arithmetic sequence:
an = a0 + d(n-1)

if we use the two terms given, setting a12 as starting term and a45 as the end term an.

170 = 38 + 33d 
170 - 38 = 33d
132 = 33d

132/33 = d
This is the common difference, use it to find the first term.

38 = a0 + (132/33)(12-1)
38 = a0 + (132/33)(11)
38 = a0 + 132/3
38 - 132/3 = a0
38 - 44 = a0
-6 = a0

The starting term is -6
