Zack reads faster so he will finish first
Pam= 126/3 = 42/1
Zack= 180/4 =45/1
Now multiply the unit rates by 5 each
Pam= 210/5
Zack= 225/5
Answer:
Step-by-step explanation:
5(-2x -10) = 25(x + 1)
-10x - 50 = 25x + 25
by transposing
-10x - 25x = 25 + 50
-35x = 75
x = -75/35
<u><em>x = 15/7</em></u>
or 2.142857..... in decimal
Hope this helps

Answer:
B) 8
Step-by-step explanation:
Triangles MNC and RSC are similar because all 3 angles are the same, so the the ratio between each side should be the same.
If NC=12 and SC=6 then triangle MNC is scaled up by 2 from triangle RSC. This means each side of MNC is 2 times bigger than on RSC. So, sense RS=4, we can multiply that by 2 to get MN=8.
Answer: B
Explanation: it says if it moved 3 points to the left 7-3=4
(-2x+10Y)(4X-6Y) can be simplified as -8x+-60Y because you have to combine like terms such as -2x and 4x.
