<span>for finding the value, as follows is the method:
in 15th of march,his bank showing a balance of $56.75.in March 20, it was $87.37 (after 5 days)
$87.37 -$56.75.=$30.62, and $30.62+$5+$13.5=$48.87. Carlos deposited in his account between the March 15 and the March 20 the amount of $48.87. So the answer is the choice B.</span>
Answer:
54 degrees
Step-by-step explanation:
If these two lines are parallel, than angles 1 and 7 are supplementary.
13x+9+5x+9=180
18x+18=180
x+1=10
x=9
Angle 6 and 7 are vertical angles, so they are equal. Therefore, angle 6 is:
5x+9=5(9)+9=54
Hope this helps!!
ANSWER

EXPLANATION
The sum of the exterior angles of a polygon is 360°
The angles were given in terms of x.
We add all and equate to 360° to obtain.

This implies that,





Answer:
Step-by-step explanation:
Remark
They are asking you to combine like terms. The total should be 180.
Givens
2 angles
Total 180
Solution
8x - 3 + 4x + 3 = 180 The threes cancel. So add what's left. They are of opposite signs, so they cancel.
12x = 180 Divide both sides by 12
12x/12 = 180 /12
x = 15
The answer is: "72" .
______________________________________________
(input value, or "x") / 10 = y = f(x);
When y = 7.2, what is the value of "x" ?
x / 10 = 7.2 ;
x = (7.2) * 10 = 72 .
