Answer: The expression for arithmetic series for seven terms is given by

\sum_{n=1}^{n=7}(2n-1)

Step-by-step explanation:

Since we have given that

1+3+5+..................

Here, a = 1

d= common difference = a₂-a₁=3-1=2

n = 7

We need to write the arithmetic series for seven terms:

\sum_{n=1}^{n=7}(2n-1)

Hence, the expression for arithmetic series for seven terms is given by

\sum_{n=1}^{n=7}(2n-1)

mars1129 [50]

Jackson sold 27 pounds of bananas and 12 pounds of grapes.

Given that Jackson runs a farm stand that sells bananas and grapes, and each pound of bananas sells for $ 1 and each pound of grapes sells for $ 2.25, and Jackson sold 15 more pounds of bananas than pounds of grapes and made $ 54 altogether, to determine the number of pounds of bananas sold and the number of pounds of grapes sold the following calculation must be performed:

  • 25 x 1 + 10 x 2.25 = 25 + 22.50 = 47.50
  • 26 x 1 + 11 x 2.25 = 26 + 24.75 = 50.75
  • 27 x 1 + 12 x 2.25 = 27 + 27 = 54

Therefore, Jackson sold 27 pounds of bananas and 12 pounds of grapes.

charle [14.2K]
Y = 12x......y = 12(4).....y = 48.....so she pays $ 48 for the old brand when buying 4 boxes

y = 8x...y = 8(4)......y = 32...so she pays $ 32 for the brand she changed to, when buying 4 boxes

so the super saving brand would save her (48 - 32) = $ 16 per month

Can someone actually answer this question pls its my 3rd time posting it and ill ive gotten was wrong or answers that make no se
andre [41]

Answer:

(-2+-5) equals -7.

Because the signs are the same, we dont change it.

(3+5) equals 8. Same like the other equation, the signs are the same so we do not change it.

Now we do (-7+8) The answer will be 1. Lets use a little graph since its hard to explain.

-8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8

Mark -7 anyway you want. (Circle it, draw a line under it, what ever you want.)

Now Move the line 8 times.

When you do that your line will stop at 1.

And thats how you do it.
