Answer:
Step-by-step explanation:
Hello,
Let's not a and b the two numbers.
<em>One number is seven less than a second number.</em>
(1) b = a - 7
<em>Five times the first is 2 more than 6 times the second. </em>
(2) 5a = 2 + 6b
(2)+5*(1) gives
5a + 5b = 2 + 6b + 5a - 35
b = 35 - 2 = 33
a = 40
The value of the first number is 
Hope this helps.

Thank you
The probability you will roll a sum of 9 is 1/4.
<h3>What is the probability?</h3>
Probability determines the chances that an event would happen. The probability the event occurs is one and the probability that the event does not occur is 0. The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.
The probability you will roll a sum of 9 = total times a sum of 9 is derived / total sample spaces
- total times a sum of 9 is derived = (3 + 6) , (6 + 3) , (4 + 5) , (5 + 4)
- Total sample spaces = 36
The probability you will roll a sum of 9 = 4/36 = 1/9

Answer:
No student liked only Nokia
Step-by-step explanation:
The information can be illustrated as shown on the Venn diagram.
The number of students who liked only Nokia is x.
The sum of all regions in the Venn diagram should be 40.
We add all to get:
Therefore no one liked only Nokia
Total weight = 12
weight of box =3
12 - 3 = 9 lbs of candles
So how many times does .75 or 3/4 go into 9?
9/.75= 12, so 12 candles were shipped
To solve the problem you must apply the corresponding formulas for calculate the area of each figure. Therefore, you have:
1-A cube where the length of each edge is 4 inches: <span>96 square inches
</span><span> A=6a^2=96 inches^2
2- A triangular prism where the area of each base is about 20 square inches, the length of each side of the base is 6 inches, and the height of the prism is 2 inches: </span><span>76 square inches.</span><span>
3- A square pyramid with a base length and slant height of 5 inches: 75</span><span> square inches.
</span><span>A=2(5)(5)+5^2=75 inches^2
4- A rectangular prism with a length of 5 inches, a width of 4 inches, and a height of 3 inches:</span>94 square inches .
A=2(4x5+3x5+3x4)=94 inches^2
