\displaystyle-\frac{3}{4}+1\frac{1}{4}=-\frac{3}{4}+\frac{4}{4}+\frac{1}{4}\\\\=\frac{1}{4}+\frac{1}{4}=\frac{2}{4}\\\\=\frac{2\cdot 1}{2\cdot 2}=\bf{\frac{1}{2}}

-3/4 +1 1/4 = 1/2

In decimal, this is -0.75 + 1.25 = 0.50.

Solve the following simultaneous equations : with the help of steps<br>1. x + 2y = 1, 3x - y = 17​
IRISSAK [1]

Answer:

x = 5, y = -2

Step-by-step explanation:

<u>Given equations:</u>

  • x + 2y = 1
  • 3x - y = 17​

<u>From the first equation we get:</u>

  • x = 1 -2y

<u>Substitute x in the second equation, find y:</u>

  • 3x - y = 17
  • 3*(1-2y) - y = 17
  • 3 - 6y - y = 17
  • -7y = 17 - 3
  • -7y = 14
  • y = -14/7
  • y = -2

<u>Find x:</u>

  • x = 1 - 2y
  • x = 1 - 2*(-2)
  • x = 1 + 4
  • x = 5

Please answer quickly<br>expand and simplify: 4(5x-3y) (x-4y) -(3x-4y)(2x+3y)​
Gekata [30.6K]

Answer: 14x^2-93xy+60y^2 Hope that helps!

Step-by-step explanation:

1. Expand by distributing terms

(20x-12y)(x-4y)-(3x-4y)(2x+3y)

2. Use the Foil method:(a+b)(c+d)= ac+ad+bc+bd

20x^2-80xy-12yx+48y^2-(3x-4y)(2x+3y)

3. Use the Foil method : (a+b)(c+d)= ac+ad+bc+bd

20x^2-80xy-12yx+48y^2-(6x^2+9xy-8yx-12y^2)

4. Remove parentheses 20x^2-80xy-12yx+48y^2-6x^2-9xy+ 8yx+12y^2

5. Collect like terms (20x^2-6x^2)+(-80xy-12xy-9xy+8xy)+(48y^2+12y^2)

6. Simplify.

And your answer would be 14x^2-93xy+60y^2
