1.solve for d under 1 can't type that means it wants d1= so
A= 1/2 d1d2
Mult by 2/1 of each side you get
2A= 1/2times 2/1 d1d2
2A= d1d2
Divide by d2 on both sides the d2 cancel on the right
2A/d2= d1
d1= 2A/d2
2.V=LWH
Divide by LH
V/LH= LWH/LH. LH cancel
V/LH= W
Hope this helps You and mom
7. -4x+y=9
Bring the 4x to the right makes it positive
Y= 4x+9
9. -3y+18x=12
-3y= -18x+12
Divide by -3 all of it
Y= 6x-4
Answer:
30 students
Step-by-step explanation:
The problem above can be solved using a Venn diagram :
Using the information given :
The number of students competing :
Band and chorus only (BnC) only = 5 - 4 = 1
Band and Orchestra (BnO) only = 6 - 4 = 2
Chorus and Orchestra (CnO) only = 7-4 = 3
Chorus only (C) = 13 - (1+4+3) = 5
Band only (B) = 14 - (1+4+2) = 7
Orchestra only (O) = 17 - (2+4+3) = 8
The Total Number of Bayview students who competed :
(8+7+5+3+2+1+4) = 30

Answer:
10x² - 25x = 0 ⇔ 5x(2x-5) = 0
the factors are 5x and 2x-5
