Answer:
136
Step-by-step explanation:
180(4-2)
=180(2)
=360
2x+3x+4+4x+16+2x+10=360
11x+30=360
11x=360-30
11x=330
divide both side by 11
x=30
Substitute the value
A:2(30)
=60
B:3(30)+4
=94
C:4(30)+16
=136
D:2(30)+10
=70
Add all to check
60+94+136+70
=360
Therefore the largest angle is 136
Answer:
100 students
Step-by-step explanation:
10% of students in 7th grade ----- 10 students
<em>Divide</em><em> </em><em>by</em><em> </em><em>1</em><em>0</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
1% of students in 7th grade ----- 10 ÷10= 1 student
<em>×</em><em>100</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
100% of students in 7th grade ----- 1 ×100= 100 students
