-3z + 7 = -7 - 10z
Add 10z to both sides
7z + 7 = -7
Subtract 7 from both sides
7z = -14
Divide by 7
Z = -2
Answer:
21 projects each
Step-by-step explanation:
3150 ÷150
Answer:
the answer is 13, because you need to divide 91 by 7.
The inequality that shows the temperature in Melbourne is 20°F ≤ x ≤ 100°F
<h3>What is an
inequality?</h3>
An inequality is an expression that shows the non equal comparison of two or more variables and numbers.
Let x represent the temperature in Melbourne.
The highest temperature ever recorded there was 109°F, hence x ≤ 109°F.
Also, the lowest temperature ever recorded there was 20°F, hence x ≥ 20.
From both statements:
20°F ≤ x ≤ 100°F
The inequality that shows the temperature in Melbourne is 20°F ≤ x ≤ 100°F
