7-(-4) is 4 units from 7 in the negative direction. See the explanation and the linear scale attached.
<h3>What direction is being referred to in the above Question?</h3>
The direction being referred to is the direction of the number on a numerical scale or Linear Scale.
In the attached linear scale, we can see that the arrow stops at 11. This is arrived at by expanding the bracket:
7 - (-4)
the subtraction signs cancel out each other creating a positive sign. Hence we have:
7 + 4
= 11.
Hence, 11 is 4 units away from 7 in the negative direction. That is going toward zero is negative or a reduction hence, to get to 7 you need to go toward the negative section of the scale.

5. so we know C is out of the option.
![1.90 \times 2](https://tex.z-dn.net/?f=1.90%20%5Ctimes%202)
so shop A and B will cost the least
The simple interest formula is I = P * r * t
P is the principal (2,000)
r is the interest rate (7% or 0.07)
t is the time (5)
2000 * 0.07 * 5 = 700
$700.00 is the interest
Joe has to pay $700.00 in interest.
Hope this helps :D
One foot is 12 inches so she must take 16 inches
3 times 4 is 12 so 4 times 4 is 16
