Answer:
4/7
Step-by-step explanation:
Multiply the number by The reciprocal of 1 2/5
4/5*5/7=20/35
Let
R = Ralph's age
S = Sara's age
First statement is translated as:
S = 3R
Second statement is translated as:
S + 4 = 2(R + 4)
Use the first equation to be substituted into the second one in terms of R which is the one we are actually going to solve for Ralph's age.
Since S = 3R, then
3R + 4 = 2(R + 4)
3R + 4 = 2R + 8
3R - 2R = 8 - 4
R = 4 years old
Answer:
x = 6
Step-by-step explanation:
The line of reflection is x = 6.
Answer:
3.125 g/cm³.
Step-by-step explanation:
The formula for density/mass/volume is d = m/v, where d is density in grams per cm cubed, m is in grams, and v is in cm cubed.
In this case, m = 25 and v = 8.0.
d = 25 / 8.0
d = 25 / 8
d = 3.125.
So, the density of the object is 3.125 g/cm cubed.
Hope this helps!
Answer:
Step-by-step explanation:
y + 6 = -2/3(x + 1)
y + 6= -2/3x - 2/3
y + 18/3 = -2/3x - 2/3
y = -2/3x - 20/3
