Answer:
Step-by-step explanation:
Use pythagorean theorem for all of the lines that are slanted then add them all together

Doubles are adding the same number together, as with 5+5=10.
With doubles +1, the numbers must be in beside each other in counting order going up or down (ex: 4, 5, 6 and 9, 8, 7). Do the SMALLEST number, double it, then add one. So, 9+8 would be 8+8=16, +1=17. You must know your doubles facts before this strategy is useful.
3. First, turn the fractions into improper fractions
11/8 + 11/4
Since we can't divide 11 by 2 to make the denominator of the first fraction 2, let's multiply both sides of the second fraction by 2 instead.
11/8 + 11*2/4*2 = 11/8 + 22/8
<u>33/8, or 4 1/8</u>
(I already answered numbers 4 and 6 in a previous question you asked)
5. 1 1/2 + 2 3/4
Obviously, we'll start by converting the fraction into improper fractions.
3/2 + 11/4
Multiply both sides of the first fraction by 2
3*2/2*2 + 11/4 = 6/4 + 11/4 = 17/4
<u>17/4, or 4 1/4</u>
- 5z^3 - z^4 + 4z^5 is the answer.
<span>the sum of three consecutive odd integers is 69. Find the integers.
-------------
1st: 2x-1
2nd: 2x+1
3rd: 2x+3
---------------------
Equation:</span>2x-1 + 2x+1 + 2x+3 = 69<span>
</span><span>6x + 3 = 69
2x + 1 = 23
-----------------
So 2x-1 = 21
And 2x+3 = 25
</span><span>let:
x be the first odd integer
x + 2 be the 2nd odd integer
x + 4 be the 3rd odd integer
solution:
1st odd integer + 2nd odd integer + 3rd odd integer = 69
x + (x+2) + (x+4)= 69
</span>
<span>3x + 6 = 69
3x = 69 - 6
3x = 63 (dividing both sides by three)
x = 21
_______________________________________
x=21
x+2=23
x+4=25
therefore, the 1st integer is 21, the 2nd is 23 and the 3rd is 25..</span>
