9 + |-78| - (-22)
Apply the absolute value which states |-x| = x.
9 + 78 - (-22)
Apply the rule that states x - (-y) = x + y.
9 + 78 + 22
Add 9 and 78.
87 + 22
Add 87 and 22.

Hey there! :)
Answer:
56.7 kg.
Step-by-step explanation:
Use the density formula to solve for the mass:
D = m/V.
Rearrange in terms of mass, or 'm':
DV = m.
Solve for the volume:
0.06 × 0.9 × 1.5 = 0.081 m³.
Plug this into the equation along with the density:
700 × 0.081 = 56.7 kg.
A graphing calculator shows the x-intercepts of the expression on the left to be -1, 4, 7.
The real solutions to the cubic equation are x ∈ {-1, 4, 7}.
