So, since both equate to y, we can solve for x by equating the equations to each other.
4x - 5 = -3
So: 4x = 2
So: x = 1/2, or 0.5
Now, y = -3, so the solution is (0.5, -3)
You can graph the two equations, and the point where they meet will be (0.5, -3).

A website had 826, 140 hits last month what is the value of the 8 in 826,140

Angelina_Jolie [31]

800,000 or eight hundred thousand.

<h3>Further explanation</h3>

Problem: The given number is 826,140.

Question: What is the value of the digit 8?

The Process:

This is a problem with place value.

Let us set the place values from 826,140 consecutively as follows.

In the thousands period: 8 hundred thousands, 2 ten thousands, 6 one thousands.
In the units period: 1 hundreds 4 tens 0 ones.

Let us say in word form: eight hundred twenty-six thousand six hundred forty.

Hence, the value of the 8 in the numbers 826,140 is 800,000 or eight hundred thousand.

Notes:

Recall that the digits in large numbers are in groups of three places, i.e.,

hundreds,
tens, and
ones (or units).

The groups are called periods, i.e.,

millions period
thousands period
ones or units period

Commas are typically used to separate the periods.

Carmen has a $350 gift card to spent at Modell's. She wants to buy 2 pairs of sneakers that cost $100 each. She wants to find th

tatyana61 [14]

Answer:

The inequality is $200 + x*$8≤ $350

Step-by-step explanation:

An inequality is an inequality between letters (unknowns) and numbers related by arithmetic operations. Its solution set is the set of real numbers that satisfy it. In other words, an algebraic inequality in which its members are linked by the signs <(less than), ≤ (less than or equal to),> (greater than) or ≥ (greater than or equal to) is called an inequality.

Solving an inequality is to find the values of the unknown for which the inequality holds. The solution of an inequality is an interval or a union of intervals of real numbers.

In this case, you know that Carmen wants to buy 2 pairs of sneakers that cost $ 100 each.So the 2 pairs of sneakers will cost Carmen:

2 * $ 100 = $ 200

On the other hand, Carmen wants to find the possible amount of socks that she can buy, knowing that a pair costs $ 8. Being x the amount of socks that she can buy, then Carmen spends on socks:

x*$8

Knowing that Carmen has a $ 350 gift card to spend at Modell's, then what she spent on sneakers and socks cannot be more than $ 350. That is to say, the sum of what was spent on sneakers and socks must be less than or equal to $ 350, because Carmen cannot spend more than she has. This is expressed by the following inequality:

$200 + x*$8≤ $350

Solving for x:

x*$8 ≤ $350 - $200

x*$8≤ $150

x≤ $\frac{150}{8}$

x≤ 18.75

Carmen can buy 2 sneakers and 18 or fewer socks with the $ 350 gift card.
