52º, 128º
Step-by-step explanation:
8. Because ∠6 is an opposite angle to ∠5, ∠6=∠5=52º;
9. Because line a//line b, ∠6=∠4=52º, so ∠7=180º–52º=128º
Answer:
310
Step-by-step explanation:
total no.of students=1872
ratio of boys to girls=7:5
sum of ratio=total of students
12/12=1872

7/12*1872/1=1092which is the number of girls
1872-1092=780which is the number of boys
difference =1092-780= 310

Answer:
1)3 2)86
Step-by-step explanation:
3h+77=SA AND 92-2h=MB
3h+77=92-2h
-77. = -77
3h= 15-2h
+2h=+2h
5h=15
H=3
“Jesse bought 10 more pencils than erasers” means P = 10 + E
“A pencil costs $0.15” means that $0.15*P was spent on pencils
“an eraser costs $.22” means that $0.22*E was spent on erasers
“He paid a total of $4.46” means that $0.15*P + $0.22*E = $4.46
15*(10+E) + 22*E = 446
150 + 37E = 446
37E = 296
E = 8 Jesse bought 8 erasers
