Answer:
y = 2
x = 5
Step-by-step explanation:
4x + 5y = 10 | ×3 |
3x - 3y = 21 | ×4 |
12x + 15y = 30
12x - 12y = 84
____________--
27y = -54
y = -54/27
y = 2
4x + 5y = 10 | ×3 |
3x - 3y = 21 | ×5 |
12x + 15y = 30
15x - 15y = 105
____________+
27x = 135
x = 135/27
x = 5
The angles diagonally opposite each other are congruent while those adjacent to each other add up to 180 degrees. You can get eight congruent angles with a transversal if the two lines are parallel, because each angle would be 90.
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 $450$
40%=0.4
0.4+1=1.4
4.5(1.4)=6.3
The answer is $6.30
