It is more appropriate to round to the nearest tenth inch because inches are normally whole numbers and when you are rounding off inches, you want to make sure that your answer is as simplified as possible so it is easier to calculate in the long run.
C. 75
70+35+x=180
70+35=105
180-105=75
The answer is 12 and 6 because twice the number which is 6 is 12
Answer:
y=-5x+9
m=-5
b=9
y=5x-4
m=5
b= -4
y=8
m=0
b=8
Step-by-step explanation:
You have to make the denominators (bottom numbers) the same via multiplication, it's best to do it to the first number they meet at. that would be fifteen (15)
5×3=15
3×5=15
you then have to multiply the numerators by the respective numbers.
2×3=6
1×5=5
you then subtract the numerators normally
6-5=1
slap back on the denominator
1/15
there's your answer.
(the number you multiply them by isn't the other denominator, it just happens to be the denominators for this equation)
