olga2289 [7]

Answer:

300+400+500=1200

Step-by-step explanation:

given total paid $2400

spend $1200 on a rent (half of his paid)

so rest he spend as a ratio of 3:4:5=1200

let x as a amount he using to pays rest of the bills so

3x+4x+5x=1200

12x=1200

x=1200/12

x=100

so he spends 3x=300

4x=400

5x=500

hope it helps you

There's a pair of points (3,5), (x,15) and a slope of 2 how do I find x​
sergeinik [125]

You have the slope and you have two points, so you can use the slope equation to find x.

b=\frac{(y_2-y_1)}{(x_2-x_1)} \\2=\frac{(15-5)}{(x-3)} \\2(x-3)=(15-5)\\2x-6=10\\2x=16\\x=8

So your answer is x = 8.

The sum of the first five terms of 3,-9,27,-81
xeze [42]

Answer:

<em>183</em>

Step-by-step explanation:

The answer above is correct, but I do want to elaborate on how to receive this answer;

This pattern takes an alternate of positive and negative numbers at a time. If you can see for each positive number, there is a negative consecutively. Imagine these values were all positive. What would then be the difference between each? 3 * 3 = 9, 9 * 3 = 27, 27 * 3 = 81, and so each number would be 3 times the other. Now let us go back to the state we have at hand, negative and positive numbers. 81 * 3 = 243, and as we alternate between negative and positive numbers, 243 should be positive as the previous number - 81, is negative. We have now received our 5th term!

The questions asks us to determine the sum of each of the terms however, so let us do so;

3 - 9 + 27 - 81 + 243,\\- 6 + 27 - 81 + 243,\\21 - 81 + 243,\\- 60 + 243,\\\\183\\Solution = 183

Hope that helps as well!
