Answer:
-300=z
Explanation:
Divide both sides by 0.070.070, point, 07:
\maroonD{\dfrac{\color{black}{-21}}{0.07}} = \maroonD{\dfrac{\color{black}{0.07z}}{0.07}}
0.07
−21
=
0.07
0.07z
start color #ca337c, start fraction, start color black, minus, 21, end color black, divided by, 0, point, 07, end fraction, end color #ca337c, equals, start color #ca337c, start fraction, start color black, 0, point, 07, z, end color black, divided by, 0, point, 07, end fraction, end color #ca337c
Hint #22 / 3
To simplify, remember that when the signs are the same, the quotient is positive. When the signs are different, the quotient is negative.
-300= \dfrac{\cancel{0.07}z}{\cancel{0.07}}−300=
0.07
0.07
z
minus, 300, equals, start fraction, start cancel, 0, point, 07, end cancel, z, divided by, start cancel, 0, point, 07, end cancel, end fraction
Hint #33 / 3
z = -300z=−300
