let Elga age be x

And So Alvin age is x+15

x+x+15=81

2x+15=81

2x=81-15

2x=66

x=66/2

x=33

Answer:

Let the age of Elga be x, the age of Alvin will be (x+15).

Given that, sum of their ages is 81.

x+(x+15)=81

2x+15=81

2x=66

x= 66/2

•°•<u>x</u><u>=</u><u>3</u><u>3</u>

<u>•</u><u>°</u><u>•</u><u> </u>The age of Elga is 33 yrs.

A small-appliance manufacturer finds that the profit P (in dollars) generated by producing x microwave ovens per week is given b
Olegator [25]

Answer:

Number of ovens must be manufactured in a given week to generate a profit of $1610  is 70

Step-by-step explanation:

We are given

A small-appliance manufacturer finds that the profit P (in dollars) generated by producing x microwave ovens per week is given by the formula

P=\frac{1}{10}x(300-x)

provided that 0 ≤ x ≤ 200

We are given

profit is $1610

so, we can set P=1610

and then we can solve for x

1610=\frac{1}{10}x(300-x)

Multiply both sides by 10

1610\cdot \:10=\frac{1}{10}x\left(300-x\right)\cdot \:10

16100=x\left(300-x\right)

16100=300x-x^2

-x^2+300x-16100=0

now, we can factor it

(x-70)(x-230)=0

we can solve for x

and we get

x=70,x=230

Since, x=230 does not lie on 0 ≤ x ≤ 200

So, we will consider only x=70

So,

Number of ovens must be manufactured in a given week to generate a profit of $1610  is 70

Solve the equation 0.25 (8z - 4) = z + 8 - 2z
Andrew [12]
Distribute
2z-1=z+8-2z
add like terms
2z-1=-z+8
add z to both sides
3z-1=8
add 1 to both sides
3z=9
divide both sides by 3
z=3
