The answer to your question is:
+4
-4, -3, -2, -1, 0, 1, 2, 3, 4
Answer:
8 cm
Step-by-step explanation:
(See the image attached for details)
- The blue segment measures 15 cm
- The green segment measures 7 cm
- The green and yellow segment when added form the blue segment
- So: ? + 7 = 15
Solve:
? + 7 = 15
Subtract 7 on both sides:
? + 7 = 15
-7 -7
? = 8 cm
Therefore, the yellow segment, or the missing side length, measures 8 cm.
4(4x)+2(x)=72
16x+2x=72
18x=72
x=4
27 sports cars
3/8 = x/72
8* blank = 72
So, since 8*9=72 you have to multiply 3 by 9 which gives you 27.
Hope this helps!
22 quarters= $5.50
10 dimes= $1.00
$5.50 + $1.00 = $6.50
I just did trial and error. I started with 20 quarters and made changes until it worked.
