Answer: x1 = 0; x2 = 5/3; x3 = 1/3
x1 + 2x2 - x3 = 3 => 2x1 + 4x2 - 2x3 = 6
2x1 + x2 - 2x3 = 1
=> 4x2 - x2 = 5
⇔ 3x2 = 5
⇔ x2 = 5/3
with x2 = 5/3, we have: x1 - x3 = 3 - 10/3 = -1/3
3x1 - 5x3 = 5 - 4.5/3 = -5/3
=> x1 = 0
x3 = 1/3

I hope this helps you :D
Commutative
The commutative property tells us that two addition and multiplication sentences are equal no matter the order.
For example:
3+4=4+3
6 x 5= 5 x 6

Answer:
x = 13, z = 184
Step-by-step explanation:
(14x-94) = 88
14x = 182
x = 13
z = 360 - 88*2 = 360 - 176 = 184
Answer:
x = 13; z = 92
Step-by-step explanation:
88 = 14x - 94
14x = 182
x = 13
180 = z + 88
z = 92

I need help with these twooo
Answer:
Question 5
We get n=42.15 and o=71.5
Question 6
We get e=15.32 and t=17.88
Step-by-step explanation:
Question 5
The triangles are similar.
So, the ratio of corresponding sides will be similar.
[tex]\frac{53}{n}=\frac{88}{70}=\frac{90}{o}[/tex]
First we will solve [tex]\frac{53}{n}=\frac{88}{70}[/tex] to find value of n.
Cross multiply
[tex]53*70=88*n\\n=\frac{3710}{88}\\n=42.15\\[/tex]
Now, we will solve [tex]\frac{88}{70}=\frac{90}{o}[/tex] to find value of o
[tex]88*o = 90*70\\o=\frac{6300}{88}\\o=71.5\\[/tex]
So, We get n=42.15 and o=71.5
Question 6
The triangles are similar.
So, the ratio of corresponding sides will be similar.
[tex]\frac{9.6}{e}=\frac{5.7}{9.1}=\frac{11.2}{t}[/tex]
First we will solve [tex]\frac{9.6}{e}=\frac{5.7}{9.1}[/tex] to find value of n.
Cross multiply
[tex]9.1*9.6=e*5.7\\e=\frac{87.36}{5.7}\\e=15.32\\[/tex]
Now, we will solve [tex]\frac{5.7}{9.1}=\frac{11.2}{t}[/tex] to find value of o
[tex]5.7*t = 11.2*9.1\\t=\frac{101.92}{5.7}\\t=17.88\\[/tex]
So, We get e=15.32 and t=17.88

28 decreased by 2.6%
Answer:
Please check the explanation.
Step-by-step explanation:
Given
28 decreased by 2.6%First we need to determine the percentage decrease such as:
Percentage decrease = 2.6% of 28
= 2.6/100 × 28
= 0.026 × 28
= 0.73
New value can be determined using the formula
New vaue = 28 - percentage decrease
= 28 - 0.73
= 27.27
What is the distance between points R and S, to the nearest tenth of a unit? A. 6.3 B. 7.2 C. 14.4 D. 20.0
Answer:
Distance of RS = 14.4 units (Approx)
Step-by-step explanation:
Co-ordinate
R (-8, -6)
S (4, 2)
Find:
Distance of RS
Computation:
Distance = √(x1 - x2)² + (y1 - y2)²
Distance of RS = √(-8 - 4)² + (-6 - 2)²
Distance of RS = √144 + 64
Distance of RS = √208
Distance of RS = 14.4 units (Approx)

The cost y (in dollars) of a gym membership for x months is y=20x+25. Graph the equation.
Answer:
The graph of the equation y = 20x+25 is attached below.
Please check the attached graph.
Step-by-step explanation:
We know that the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptIn our case, we are given that the cost y (in dollars) of a gym membership for x months is:
[tex]y=20x+25[/tex]
comparing with the slope-intercept form of the line equation
Here:
The slope of the equation is: m = 20
The y-intercept is: b = 25
The graph of the equation y = 20x+25 is also attached below.
From the graph, it is clear that the graph of the line crosses the y-axis at y = 25.
Thus, the point (0, 25) represents the y-intercept of the function.
Please check the attached graph.
