Answer:
density = 0.7 gm/cm³
Explanation:
Density can be calculated using the following rule:
Density = mass / volume
We are given that:
mass = 2.75 grams
volume = 4 cm³
Substitute with the givens in the above equation to get the value of the density as follows:
density = 2.75 / 4
density = 0.6875 which is approximately 0.7 gm/cm³

-8y + 9x = -5
8y + 7x = -75 +
--------------------------
/ 16x = -80
x = -80/16
x = -5
8y + 7x = -75
8y - 35 = -75
8y = -75 + 35
8y = -40
y = -40/8
y = -5
Answer : x = y = -5
Answer:
17y+24
Step-by-step explanation:
simplify so the first step would be to multiply whats in the parentheses by the number outside in this case its 6 youd get:
12y+24+5y
then you simplify farther by adding like terms
17y+24
A = l x w
l = w+14
792 = w +14 x w
792 = w² +14w
w² +14w-792=0
w= -36 w=22
You can't have a negative length so the width = 22
Length = 22+14
Length = 36 inches
