You need to subtract 5-3 first because of PEMDAS petri did it wrong because she did 5 to the power of 2 and 2 to the power of 2 instead of actually subtracting 5-3. So the answer is the last option:)

Write the first four terms of the sequence. rule start at 5 1/2, add 1 1/5
Hitman42 [59]

Answer:

5\frac{1}{2},6\frac{7}{10},7\frac{9}{10},9\frac{1}{10}

Step-by-step explanation:

The first term of the sequence is

a_1=5\frac{1}{2}

To find the second term add 1\frac{1}{5} to the first term;

a_2=5\frac{1}{2}+1\frac{1}{5}=6\frac{7}{10}

To find the third term add 1\frac{1}{5} to the second term;

a_3=6\frac{7}{10}+1\frac{1}{5}=7\frac{9}{10}

To find the fourth term add 1\frac{1}{5} to the third term;

a_4=7\frac{9}{10}+1\frac{1}{5}=9\frac{1}{10}

The first four terms are

5\frac{1}{2},6\frac{7}{10},7\frac{9}{10},9\frac{1}{10}

True or False:
fredd [130]
The answer is <em>False
</em>
<em />
<em />A Perfect Square Trinomial should be in the form of this:

a^{2} + 2ab +  b^{2}

The following, 100x^{2} -10xy+ y^{2}, definitely does not follow the rule given and, therefore, is not a Perfect Square Trinomial. 

I hope this helped!! Have an amazing day :)<em>

the combined score for yakubu in geography, economics and science is 194. he scored twice as many marks in economics as in geogr
SVETLANKA909090 [29]

The scores of geography, economics and science are 38, 76, 80 respectively.

Let Yakubu scored x marks in geography.

Given that the score of him in economics is twice of the score of him in geography.

So, his score in economics = 2x

Again it is given that, the score in science is 4 more than the score in economics.

So the score in science = 2x+4

According to question the combined total score is 194. So the suitable equation is,

x+2x+2x+4 = 194

Solving the equation we get,

5x+4 = 194

5x = 194-4

5x = 190

x = 190/5

x = 38

So the score in geography = 38

the score in economics = 2x = 2*38 = 76

the score in science = 2x+4 = 2*38+4 = 76+4 = 80

Hence the scores of geography, economics and science are 38, 76, 80 respectively.
