Answer: In the equations that you have given, we have a dependent system.
2x + y = 8 (I assumed that you meant to type y instead of 7)
6x + 3y = 24
To use Cramer's Rule, we have to take the determinant of 3 different matrices written in the problem. Taking the determinant of the coefficient matrix produces a zero.
2 1 This is the coefficient matrix.
6 3
6 - 6 = 0
Since this is 0, the rest of the work will be undefined meaning the systems are dependent (or they are the versions of the same equation).
Answer:
Step-by-step explanation:
(King of Diamonds) = 1/52
(A Heart) = 1/4
(Red Three) = 1/26
(Red Card) = 1/2
see the attached figure to better understand the problem
we know that
1) If angle 1 and angle 2 are complementary angles
then
m∠1+m∠2= ------> equation A
2) If angle 1 and angle 2 are congruent angles
then
m∠1=m∠2 ------> equation B
Substitute equation B in equation A
m∠1+(m∠1)=
2m∠1=
m∠1=
therefore
<u>the answer is</u>
Answer:
450
Step-by-step explanation:
Solution for What is 75 percent of 600:
75 percent * 600 =
(75:100)* 600 =
(75* 600):100 =
45000:100 = 450
Now we have: 75 percent of 600 = 450
Question: What is 75 percent of 600?
Percentage solution with steps:
Step 1: Our output value is 600.
Step 2: We represent the unknown value with $x$x.
Step 3: From step 1 above,$600=100\%$600=100%.
Step 4: Similarly, $x=75\%$x=75%.
Step 5: This results in a pair of simple equations:
$600=100\%(1)$600=100%(1).
$x=75\%(2)$x=75%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
600
x=
100%
75%
Step 7: Again, the reciprocal of both sides gives
x
600=
75
100
Therefore, $75\%$75% of $600$600 is $450$
Answer:
$3787.5
Step-by-step explanation:
Given data
Cost price= $25,000
Rate of decrease= 7%
Time= 2020-2026= 26 years
Let us apply the formula
A= P(1-r)^t
substitute
A= 25000(1-0.07)^26
A=25000(0.93)^26
A= 25000*0.1515
A= $3787.5
Hence the worth will be $3787.5
