Answer:
x=40
Step-by-step explanation:
x=4(x+10)÷5
x=(4x+40)÷5
5x=4x+40
x=40

If a = 4 and d = 3,

Answer: The general equation for the nth term is 3n + 1.---------------------------------------------------------------------------------------
L=7+w
P=(12x+14)=2(6x+7)
l+w= P/2 = 2(6x+7)/2= 6x+7
l+w=6x+7
2l = 6x+7
l = (6x+7)/2
l=7+w
-> w= l-7
= [(6x+7)/2] -7
= (6x+7-14)/2
= (6x-7)/2
Answer:
37 beads
Step-by-step explanation:
Given that:
Adel : Claire = 7 : 4
Let Adel be = A; &
Let Claire be = C
A: C = 7 : 4

7C = 4A
--- (1)
When Adel gave 68 beads to claire, we have:
C + 68 = 25:41

25(C + 68) = 41A
C + 68 = 
--- (2)
Equating (1) and (2) together;




- 187 A = 175 × (-68)
-187 A = - 11900
A = - 11900/ -187
A ≅ 64
From;

C = 36.57
C ≅ 37 beads
