Please help! I don't understand this!! Solve using substitution:

1 answer:

3 0

First you solve for y for the top equation, making the top equation become y=-3+5=x.
now we have to substitute that into 3x-8y=24.

that gives you 3x-8(-3+5x)=24
now you solve it for x, which is 0.
now you have to substitute 0 for x in the equation y=-3+5x, so it now becomes y=-3+5*0.
when you solve this for y, you get -3. this means your answer is y=-3 and x=0

REQUIRED CHART :

The required chart has been attached

Answer:

31.8%

30.0%

Step-by-step explanation:

Required :

To obtain the Difference between Sweden and United States high and medium categories to the nearest %

Sweden :

High category = $23.51

Medium category = $15.73

United States :

High category = $34.48

Medium category = $22.46

Percentage Difference :

High category : (34.48 - 23.51) / 34.48 * 100% = 31.8%

Medium category : (22.46 - 15.73) / 22.46 * 100% = 29.96% = 30.0%

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 {}.
