Answer:
x=-20
Step-by-step explanation:
Given
-6(x+7)= -4x - 2
First of all, we have to solve brackets
So,
-6x-42=-4x-2
To find the solution of this equation, we have to isolate x on one side of the equation.
Adding 4x on both sides
-6x-42+4x = -2-4x+4x
-2x-42 = -2
Adding 42 on both sides
-2x-42+42 = -2+42
-2x=40
Dividing both sides by -2
-2x/2 = 40/-2
x = -20
The equation has only one solution which is x=-20 ..
Answer:
a) £10.50
b) £5.40
Step-by-step explanation:
In this context, "of" means "times".
__
<h3>a)</h3>
1/4 × £42 = £(42/4) = £10.50
__
<h3>b)</h3>
2/5 × £13.50 = £(2·13.50/5) = £(27/5) = £5.40

Answer:
72.66 in³
Step-by-step explanation:
The volume of a cylinder of radius r and height h is given by V = πr²h.
Here we have V = πr²h = π([2.8]/2 in)²(11.8 in) = π(1.96 in²)(11.8 in) = 23.1 π in³, or approximately 72.66 in³
