Answer:
The answer is attached below
Step-by-step explanation:
Simple, first we add the numbers up. 3+3+3+3=12, you asked what is the probability that it is a bag of peanuts, their are 3 bags of peanuts. Let's make a fraction. The fraction is going to be 3/12, we can simplify 3/12 into 1/4. So, the answer is A. 1/4
Answer: 5 pounds strawberries and 5 pounds blueberries
Step-by-step explanation:
s+b=10
2s+b3=25
b=10-s
2s+3(10-s)=25
2s+30-3s=25
-s=-5
s=5
b=10-5
b=5
Answer:
x = 15
Step-by-step explanation:
AEB is a right angle, a right angle is 90 degrees
this means 5x+15 needs to equal 90
plug in 15 for x
5 x 15 + 15 = 90
<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>
