Can anyone pls help again it was 6 questions I got wrong so pls anyone, so I might post a lot but I really need this.
Strike441 [17]

To solve this we must first add up all the values.

3.29+1.28+2.49+1.59=8.65

$8.65 is our total.

Now we find 8% of the total amount. In order to do this we must first find the decimal form of the percent. It's quite simple all we have to do is move the decimal point two spaces forward. We add a 0 in front of the decimal point after that.* (True for all one digit percents)*

8.00%+ 2 spaces forward = 0.08

Then we simply multiply the percent times the total amount.

$8.65*0.08=0.69

We add the last value to the total amount and we have our answer.

$8.65+0.69=$9.34

The total amount benjamin is going to pay is $9.34 (including tax)

Hope this helps and have a great day!

Can anyone help me with this problem
Kisachek [45]
In order to do this you first have to solve the parenthesis. Why because the pemdas tells you so, first parenthesis then exponents then multiplication then division then addition and then subtraction. So first subtract 7 from 9 to get (2)^-3 now multiply 2 3 times. -2*-2*-2 to get -8

Hope this helps

Unit4: Congruent Triangles Hw 1: Classifying Triangles Gina Wilson (All things algebra) 2014

Answer:

  • 12. x = 6, side = 83
  • 13. x = 18, side = 29
  • 14. x = 11, sides = 74, 74 and 37
  • 15. x = 23, sides = 95, 95 and 108

Step-by-step explanation:

<em>11 is incomplete, can't solve</em>

12

<u>The triangle is equilateral, so all sides are equal, using one pair to find x:</u>

  • 13x + 5 = 17x - 19
  • 17x - 13x = 5 + 19
  • 4x = 24
  • x = 6

<u>Each side is:</u>

  • 13*6 + 5 = 78 + 5 = 83

13.

<u>Sides are equal as triangle is equilateral</u>

  • QR = 2x - 7
  • RS = 5x - 61
  • QS = x + 11

<u>Finding x by comparing two sides</u>

  • 2x - 7 = 5x - 61
  • 5x - 2x = 61 - 7
  • 3x = 54
  • x = 18

<u>Sides are equal</u>

  • 18 + 11 = 29

14.

<u>Equal sides of isosceles triangle:</u>

  • CD = DE
  • 9x - 25 = 6x + 8
  • 9x - 6x = 8 + 25
  • 3x = 33
  • x = 11

<u>Sides are</u>

  • CD = DE = 9*11 - 25 = 99 - 25 = 74
  • CE = 10*11 - 73 = 110 - 73 = 37

15.

<u>Equal sides of isosceles triangle WXY, WX = WY</u>

  • WX = 4x + 3
  • WY = 7x - 66
  • XY = 5x - 7
  • 4x + 3 = 7x - 66
  • 7x - 4x = 3 + 66
  • 3x = 69
  • x = 23

<u>Sides are:</u>

  • WX=WY = 4*23 + 3 = 95
  • XY = 5*23 - 7 = 108
