How can you subtract two integers without number lines or counters

1 answer:

8 0

For example:

12 - 10 = ?

Start with the numbers to the far right; take your 2 from the 12 draw a curving line from that 2 to the 0 in 10; ask what is 2 minus zero? 2!

Draw a curving arrow from the 1 in 12 to the 1 in 10. And ask, what is one minus one ?
Zero.

Try that with other numbers

Answer: (0, -3/7)

Step-by-step explanation:

The Y-intercept would be the value of y when x is at 0, which is when the Y axis is intercepted. -3/7 is the starting position of the function when the the X = 0.

Can someone please do this for me?

san4es73 [151]

Answer:

64°

Step-by-step explanation:

So supplement angles are equal to 180, so first our two angles added together will be 180:

x + x = 180

Now one of these angles is 6 greater than half:

x + (x/2 + 6) = 180

Then we will solve for x:

x + (x/2 + 6) = 180

x + x/2 + 6 = 180

x + x/2 = 174

$\frac{3}{2}$ x = 174

x = 116

Plug it back in:

x + (x/2 + 6) = 180

x/2 + 6

(116)/2 + 6

To check:

116 + 64 = 180 ✓

Y=3x + 4 solve this system ?

user100 [1]

→ Y = 3x + 4

→ Y = 7x

Hence, Value of Y = 7x

This process can only be done when we're using the way for linear equation (Shifting both sides) [Each value)..
