one orange and one apple cost 1.05, two oranges and three apples cost $2.75, how much do two apples cost?
Nimfa-mama [501]
If you would like to know how much do two apples cost, you can calculate this using the following steps:

o ... the cost of one orange
a ... the cost of one apple

1 * o + 1 * a = $1.05
2 * o + 3 * a = $2.75
_______________
o + a = 1.05 ... o = 1.05 - a
2 * o + 3 * a = 2.75
2 * (1.05 - a) + 3 * a = 2.75
2.1 - 2 * a + 3 * a = 2.75
a = 2.75 - 2.1
a = $0.65

o = 1.05 - a = 1.05 - 0.65 = $0.4

2 * a = 2 * 0.65 = $1.3

The correct result would be: Two apples cost $1.3.

Identify the factors of the terms of the expression. <br>3). 5+6a+11b<br>4). 13m-2n​
xeze [42]

Answer:

factors are 5, 6, a, 11, b

Step-by-step explanation:

3)   5 + 6a + 11b

<u>Algebraic expressions: 5 + 6a + 11b </u>

Are combinations of numbers, variables, and at least one arithmetic.

<u>Term are: 5, 6a, 11b</u>

Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable(s).

<u>Factors are: 5, 6, a, 11, b </u>

Something which is multiplied by something else. A factor can be a variable, number,  a term, or a longer expression.

<u>Coefficient: 6, 11 </u>

The numerical factor of a multiplication expression that contains a variable.

 

<u>Constant: 5 </u>

A number that cannot change its value.

4).  13m-2n​ (note: it applies as above)

A spinner is divided into many different color sectors. Some sectors are larger than others. The spinner was spun 300 times. The
Furkat [3]
Solutions 

We know that <span>a spinner was divided into many different color sectors. Some sectors are larger than others. The spinner was spun 300 times. The results were tallied up and were written in a table. 

</span><span>Red:93

Blue:59

Green:105

Yellow:43
</span>
The spinner landed the highest on green. To find <span>the probability that the next spin will land on green we have add all the numbers and simplify them.  

93 + 59 + 105 + 43 = 300 

Out of 300 the spinner landed to green 105 times. We have the fraction 105/300. 

105/300 can be reduced. To reduce the fraction we need to the GCF of 105 and 300. The GCF is 15. 

</span>We can reduce the fraction by dividing the numerator and denominator by the GCF = 15. 

105 ÷ 15 = 7 

300 ÷ 15 = 20 

Our new fraction is 7/20 

The <span>probability that the next spin will land on green is 7/20. 
</span>≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
<span>
To get the answer to part (B) we have to add the results of red and green then simplify. 

93 + 105 = 198 

The fraction is 198/300. </span><span>198/300 can be reduced. To reduce the fraction we need to the GCF of 105 and 300. The GCF is 6. 

</span>We can reduce the fraction by dividing <span>the numerator and denominator by the GCF = 6.

</span>198 ÷ 6 = 33

300 ÷ 6 = 50<span>

The new fraction is 33/50 

</span>The probability that the next spin will land on either green or red is <span>33/50. 
</span>
