Answer:
B
Step-by-step explanation:
Start by writing the ratios equal to each other since they are equivalent.
Notice if you divide 21/3 = 7. Since they are equa then x/3=10. What number divided by 3 equals 10? x=30
Answer:
you would do the positive number and then the fraction. for example if i had 2 1/2 i would move over on the x line if it was the first number or y line if it was the second number. say it was x, i would move toward positive numbers 2 times and the half way to 3 since 2 1/2 is a mixed fraction
Step-by-step explanation:
Use the distance formula: x=sqrt((x2-x1)^2+(y2-y1)^2)
Plug in ordered pairs for the variables:
x=sqrt((2-2)^2+(8-3)^2)
x=sqrt(0+25)
x=sqrt(25)
x=5 or -5
Since distance is ALWAYS positive, it's 5 units

3 - 18 + 2
= -13
you should do this question by order of operations.
