Answer:
x = 9/4
Step-by-step explanation:
Locate point G on segment DE so that DG = 1 and GE = 4. CG is parallel to AD, so ΔCGE ~ ΔABC. Corresponding sides are proportional.
AB/BC = CG/GE
x/1 = 9/4
x = 9/4
_____
<em>Additional comment</em>
Using the given triangles, you can write the proportion statement as ...
(9+x)/x = 5/1
We judge this to take more steps to solve, so we prefer the method shown above.
Answer:
Yes, the scale factor is 4.
Step-by-step explanation:
If you times the length, 3, and the width, 5, by 4, you'll get 12 as your length and 20 as your width.
Subtract 7 from both sides
x=-4
Answer:
<u>3,600 from $26 tickets and 1,400 from $40 tickets. </u>
Step-by-step explanation:
Let x = number of $26 tickets and y= number of $40 tickets
x + y = 5000 ⇒ x = 5000 - y
26x + 40y = 149,600
26(5000 - y) + 40y = 149600
130,000 - 26y + 40y = 149600
14y = 19600
y = 19600/14 = 1,400
x = 5000 - 1400 = 3,600
So, <u>3,600</u> from $26 tickets and <u>1,400</u> from $40 tickets.
1400 is the answer hope this help
