No Solution
When you do the substitution method, you would have the x and y variables equal to zero. In systems of equations, the equations are equal with each other.
20x-8y=-5
10x-4y=-4
20x-8y=-5
-2(10x-4y=-4)
20x-8y=-5
-20x+8y=8
The 20x and -20x cancel out
The -8y and 8y also cancel out. Thus leaving -5 and 8
According to system of equations, the equations must be equal. Additionally, -5 does not equal to 8.
Therefore, the answer is no solution.
2(3x + 1) ( x + 1)
Trust me, this is correct. I ran it through i calculator
Answer:
Length of the other side of the backyard is 80.4 feet.
Step-by-step explanation:
Let the dimensions of the Liam's rectangular backyard = 85 feet × a feet
Diagonal of the rectangle, AD = 117 feet
When we apply Pythagoras theorem in ΔABD,
AD² = AB² + BD²
(117)² = (85)² + BD²
a² = 13689 - 7225
a = √6464
= 80.399 feet
a ≈ 80.4 feet
Therefore, length of the other side of the backyard is 80.4 feet.
Answer:
2.4274
Step-by-step explanation:
This is just a simple multiplication problem.
One way to do this is by converting both decimals into fractions:
1.06 = 1 + 0.06 = 1 + 6/100 = 1 + 3/50 = 53/50
2.29 = 2 + 0.29 = 2 + 29/100 = 229/100
Multiplying these two fractions, we get:

Now, we can just convert this into a decimal by using a calculator:
12137/5000 = 2.4274, which is our answer.
Of course, you could just put the numbers in a calculator, which would be much less time-consuming.
