Answer:
26 degrees below zero
Step-by-step explanation:
add the two numbers together and since 12 below zero would be -12 and it drops 14 more it would be -12 - 14 which would lead to -26 because since both are negative its basically adding then putting the negative sign in front.
Answer:
student a answered correctly
Step-by-step explanation:
student b didn't multiply the crossproducts
For this inequality x is greater than or equal to 12
1. 3x-6+2x+108+88=360
5x=170
x=34
2. figure B
<span>The simple interest formula is:
A = P · (1 + r · t)
where:
A = total amount
P = principal
r = rate
t = time
Let's solve for r:
A = P + P · r · t
P · r · t = A - P
r = (A - P) / (P · t)
The quantity A - P is defined as the Interest, therefore:
r = I / (P <span>· t)
= 1020 / (8500 </span>· 4)
= 0.03
Therefore the rate was 3%.
