B = 1/4c + 14
d = 5/4c - 2
b = d

1/4c + 14 = 5/4c - 2
1/4c - 5/4c = -2 - 14
-c = - 16
c = 16 <=== chris got 16 correct

b = 1/4c + 14
b = 1/4(16) + 14
b = 4 + 14
b = 18 <=== Brian got 18 correct

d = 5/4c - 2
d = 5/4(16) - 2
d = 20 - 2
d = 18 <=== damien got 18 right also

Vladimir79 [104]

Answer: e) 6

Step-by-step explanation:

Let x be mother + children = 18

Father's age = 38

Average age of the family = 14

38 + 18x /( x + 1 )= 14

Opening the bracket

38 + 18x = 14x + 14

Collecting like terms

24 = 4x

x = 6

no of children in the family is 6.

Have I been solving these equations correctly?
Tresset [83]

14)


2(-3)² => 2(-3)(-3) => 2*9 = > 18


27+18-11 => 27 + 7 = > 34.


16)


\bf p(x)=\cfrac{x^2-4}{2x+1}\implies p(-8)=\cfrac{(-8)^2-4}{2(-8)+1}\implies p(-8)=\cfrac{64-4}{-16+1} \\\\\\ p(-8)=\cfrac{60}{-15}\implies p(-8)=-4


17)


\bf h(x)=3\cdot 9^x\implies h(-2)=3\cdot 9^{-2}\implies h(-2)=3\cdot \cfrac{1}{9^2} \\\\\\ h(-2)=\cfrac{3}{9^2}\implies h(-2)=\cfrac{3}{81}\implies h(-2)=\cfrac{1}{27}

Convert 15% to decimals. You can do this by dividing by 100.

\frac{15}{100}=0.15

Now, take the total amount of the sales and multiply it by this decimal.

59,500*0.15=8925
