Eraser cost €0,2

Step-by-step explanation:

Cost of ereaser - x

Cost of pencil - x + 1

2x + 1 = 1,4

2x = 0,4

x = 0,2

What is the solution of the equation? A. –5, 11 B. 5 C. 11 D. –11

rjkz [21]

Answer:

The solution is -5 or 11

Step-by-step explanation:

We are given the equation;

$4(3-x)^\frac{4}{3}-5=59$

We are supposed to solve the equation;

Taking 5 to the other side;

$4(3-x)^\frac{4}{3}=59+5$

$4(3-x)^\frac{4}{3}=64$

Dividing both sides by 4

$(3-x)^\frac{4}{3}=\frac{64}{4}$

$(3-x)^\frac{4}{3}=16$

We can cube both sides;

$((3-x)^\frac{4}{3})^3=16^3$

$(3-x)^4=4096$

Then we can get the fourth root on both sides of the equation;

$\sqrt[4]{ (3-x)^4} =\sqrt[4]{4096}$

We get;

$3-x=+8 or -8$

Solving for x

$3-x=8 and 3-x=-8$

Therefore;

$x=-5 or 11$

Therefore, the solution is -5 or 11

I need help with p=2l+2w and solve for w

xxMikexx [17]

remember, you can do anything to an equation as long as you do it to both sides

try and isolate the variable you are solving for and divide it by its constant

p=2l+2w

minus 2l from both sides

p-2l=2w

divide both sides by 2

$\frac{p-2l}{2}=w$

$w=\frac{p-2l}{2}=w$

which can also be simplified to

$w=\frac{p}{2}-l$
