Answer:

5 lbs

Step-by-step explanation:

1) x = lbs. of coffee at $7 per lb

2) (7)(x) + (4)(10) = (5)(x + 10)

3) 7x + 40 = 5x + 50

7x - 5x = 50 - 40

2x = 10

x = 5 (lbs. of coffee at $7 per lb.)

If a person gets paid $290 a load and receive 5% increase on top of that, how much more is he getting paid?

lesya [120]

That person is getting $14.50 more. Since he gets a 5% increase from the set $290, you must multiply .05 (the percentage) with 290 (that person's original load payment). When you do so, you get $14.50 and that would be how much more the person is getting paid.

The set of natural numbers x that satisfy x + 8 = 5

Maksim231197 [3]

Answer:

The set of natural numbers can be denoted as: {} (null set) because no natural number will satisfy the given equation.

Step-by-step explanation:

Given equation:

$x+8=5$

To find the set of natural numbers that satisfies the above equation.

Solution:

In order to find the set of solutions for the equation, we will solve it for $x$

We have:

$x+8=5$

Subtracting both sides by 8.

$x+8-8=5-8$

∴ $x=-3$

Thus, we get only one solution for $x$ that satisfies the given equation but it is not a natural number. -3 is an integer.

Set of natural numbers {1,2,3,4,5,6........}

Thus, we can say the set of natural numbers that satisfies the equation is a null set {}.
