Answer:

  • 5 and 3

Step-by-step explanation:

Let the numbers be x and y.

<u>The equations are:</u>

  • x - y = 2
  • 2x + y = 13

<u>Add up the equations to eliminate y and solve for x:</u>

  • x - y + 2x + y = 2 + 13
  • 3x = 15
  • x = 15/3
  • x = 5

<u>Now find the value of y:</u>

  • y = x - 2
  • y = 5 - 2
  • y = 3

Let the numbers be a and b

  • a-b=2--(1)
  • 2a+b=13---(2)

Adding both

\\ \sf\longmapsto 3a=15

\\ \sf\longmapsto a=5

Putting in eq(1)

\\ \sf\longmapsto 5-b=2

\\ \sf\longmapsto b=5-2

\\ \sf\longmapsto b=3

Please I need help on solving for x
Sedaia [141]

Answer:

34^o=1/2((3x-2)^0-(x+6)^o)

68^o=3x^o-2^o-x^o-6^o

68^o+8^o=2x^o-8+8^o

76^o=2x^o-->x=38^o

\huge\boxed{\boxed{\underline{\textsf{\textbf{x=38}}}}}

What is the scale factor of triangle abc and triangle def​
Thepotemich [5.8K]

Answer:

The answer is 6

Step-by-step explanation:

ABC is 72, 66, 42 and DEF is 12, 11, 7

simply divide the largest shape measurements by the smaller one.

72÷12

66÷11

42÷7

you get 6 in all of them, this technique may not work all the time.

1. How do you find the slope in a graph?
Karolina [17]
1. Pick two points on the line and determine their coordinates.

2. Determine the difference in y-coordinates of these two points (rise).

3. Determine the difference in x-coordinates for these two points (run).

4. Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
