Answer:
240
Step-by-step explanation:
remember that to get from positive to negative you have to go from positive to 0 then to negative .
however the easiest way of solving this is
add both the values , ignore the sign
130 + 110
the difference in the temperature is :
= 240 degrees
Answer:
y = m x + b equation of a straight line
m m' = -1 condition for perpendicular lines
If y = 4 x - 7 then m = 4 so m' = -.25
Y = -.25 X + A we need to find A
A = Y + .25 * 8 = 2 + 2 = 4
Y = -.25 X + 4
Check:
2 = -.25 * 8 + 4 = -2 + 4 = 2
Answer:
27/14
Step-by-step explanation:
you can cross multiply and simplify before you start. that way it makes it a lot easier
Answer:
Step-by-step explanation:
Using I=PRT (interest= principal times rate times time) we can solve the problem
12800 times 0.15 (15%) =1920 then you multiply it by time and then you have your answer
