The two numbers are illustrations of system of equations
The two numbers are 2.7 and 37.3
<h3>How to determine the two numbers?</h3>
Let the numbers be x and y.
So, we have the following equations
x + y = 40
xy = 100
To determine the value of the variables, we simply plot the graph of both equations
From the graph, we have the following result
(x,y) = (2.7, 37.3)
Hence, the two numbers are 2.7 and 37.3

First, let's define the variables d and q as follows:
d: total number of dimes
q: total number of quarters.
"Joan has an equal number of dimes and quarters" means that d=q.
"...with <span>with a total value of $1.40</span>" means that
0.1 d + 0.25 q =1.40. ***
This is because Joan has a total of d dimes each with a value of 0.1$, and a total of q quarters, each with a value of 0.25.
Since d=q, we can write the equation *** as:
0.1 q +0.25 q=1.40
0.35 q=1.40
q=1.40/0.35 = 4.
Thus, Joan has a total of 4 quarters, and 4 dimes.
Answer: 8 coins.
2/(√5 -√6). Multiply Numerator and Denominator by the conjugate of
(√5 - √6) that is : (√5 + √6)
2(√5 + √6) / [(√5 - √6)(√5 + √6)] = 2(√5 + √6) / (5-6) =2(√5 + √6) / (-1)
-2(√5 + √6) or -2√5 - 2√6

Step-by-step explanation:
65/(-5)=-13
it happened because if we divide 65 by 5 we will get 13
for instance if we multiply 5x12=60 and if we multiply 5x13 we get 65 so after dividing we r getting -13 the sign minus is coming because there was -5
hope it helps
