### Final answer:

### Explanation:

### Learn more about System of Equations here:

The solution to the given system of equations is obtained through substitution. The process involves replacing a variable in one equation with an expression from the other. The final solutions are x1=1 and x2=0.

The system of equations in question is:

1) x1 - x2 = 1

2) 3x1 + x2 = 3

The method to solve this system is through substitution or elimination. First, rewrite the first equation x1 = x2 + 1. This allows us to substitute x1 - 1 for x2 in the second equation, yielding 3(x2 + 1) + x2 = 3, simplifying to 4x2 + 3 = 3. Solving for x2, we get x2 = 0. Substituting x2 into x1 = x2 + 1, we conclude that x1 = 1. Thus, the solution to the system is **x****1**** = 1**, **x****2**** = 0**.

**Answer:**

**Step-by-step explanation:**

BD - 5 = Y

BD = Y + 5

B = (Y + 5)/D

y=BD-5

5+y=BD

B=D(y+5)

5+y=BD

B=D(y+5)

The graph goes up by 10 each time. And if we start at the bottom of the graph, and count up to where the line hits another point of the graph. It goes up by 30, and moves right 10. So that means the slope is 3. Hope this helps!

The true statement is ∠HLM is **bisected **byLI

**Bisect**means to divide a geometric figure to two**equal**half.- Dividing line is
**bisector.**

Given that ∠KLH=120°

We know that **angle **of **straight line** is **180°**

∴∠KLM=180°

∠KLH+∠HLM=180°

120°+∠HLM=180°

∠HLM=60°

From figure, ∠HLI=30° and ∠ILM=30°

Line LI cuts the angle HLM into two equal parts such as HLI and ILM.

Therefore, ∠HLM is **bisected by **LI

Step-by-step explanation:

**The height and length of the box to the nearest tenth will be 10.6 inch and 7.4 inch respectively.**

*Explanation*

Suppose, the height of the box is inch

As the length of the box is 3.2 in. less than the height, so the length will be:

Given that, the width of the box is 2.3 inch. and the volume is 180.4 inch³

__Formula for Volume of a box:__

So, the equation will be....

Now using quadratic formula......

(Negative value of is ignored as the height can't be negative)

**So, the height to the nearest tenth will be 10.6 inch and the length will be: **

The** number is 442 **which is obtained after decreasing 520 by 15% **the answer is 442.**

It's the **ratio **of **two integers **stated as a fraction of a **hundred parts**. It is a metric for comparing **two sets **of **data**, and it is **expressed **as a **percentage **using the **percent symbol**.

**Let x be the number that is obtained after decreasing 520 by 15%**

**= (100 - 15)% of 520**

= 85% of 520

= 0.85×520

**= 442**

Thus, the** number is 442 **which is obtained after decreasing 520 by 15% **the answer is 442.**

Answer:

442

Step-by-step explanation:

If you want to decrease 520 by 15%, you have to multiply 15% by 520 first, which is 78. Next, you have to minus 78 from 520. Now you get 442!
