Answer:
a = 
x = 
Step-by-step explanation:
Let's solve for a.
8x−5x+4−x=ax+8
Step 1: Flip the equation.
ax+8=2x+4
Step 2: Add -8 to both sides.
ax+8+−8=2x+4+−8
ax=2x−4
Step 3: Divide both sides by x.
Let's solve for x.
8x−5x+4−x=ax+8
Step 1: Add -ax to both sides.
2x+4+−ax=ax+8+−ax
−ax+2x+4=8
Step 2: Add -4 to both sides.
−ax+2x+4+−4=8+−4
−ax+2x=4
Step 3: Factor out variable x.
x(−a+2)=4
Step 4: Divide both sides by -a+2.
Hope this helps!

Second one if you distribute the first expression you get the second equation so the expressions are equivalent
We have an equation: 432/?= 3/5
Cross multiply:
3*?= 432*5
⇒ ?= 432*5/3= 720
720 students use regular pencils~
<span>Ratio students to classroom in school A equals 216:12 which simplifies to 18:1. Ratio students to classroom in school B equals 104:4 which simplifies to 26:1.Total students combining school A and B equals 216+104=320 and Total classroom 12+4=16, if both school combined are assumed to be a single school C, than ratio of of students to the classroom in school C equals 320:16 which simplifies to 20:1 which means 20 students in every classroom, now total students in 4 classroom of School C equals 20x4=80, these 4 classroom are separated as School B and other 12 classroom School A, now ratio still 20:1 (same in both schools).
initially students in School B were 104 and now are 80, then total students transferred equals 104-80= 24.</span>
Given:
6 | 1 means a score of 61.
The scores of the students from the stem-and-leave are
61, 62, 63, 71, 73, 75, 77, 78, 78, 79, 82, 82, 84, 85, 89, 95, 96, and 99.
Required:
We need to find the lowest score in the 80s, the highest score overall, and the number of students who scored in the 70s.
Explanation:
The scores in the 80s are
82, 82, 84, 85, and 89.
The smallest score is 82.
The lowest score in the 80s is 82.
