Answer:
-63
Step-by-step explanation:
Add 7 to both sides
X/-3 -7 =14
+7 +7
‐-------------------
X/-3= 21. ( multiply both sides by -3 to isolate x)
X/-3 × 3= 21 ×-3
X= -63
Answer:
the difference in these two temperatures is 146.3°C
Step-by-step explanation:
The computation of the difference in these two temperatures is as follows:
= Highest temperature - lowest temperature
= 58.0°C - (-88.3°C)
= 58.0°C + 88.3°C
= 146.3°C
Hence, the difference in these two temperatures is 146.3°C
It is determined by the applying the above formula and the same is relevant
I’m in algebra 1 so no idea but i would only guess that the slope is -1 and y intercept is 5
Answer:
Step-by-step explanation:
85+x+x=89
85+2x=89
2x=89-85
2x=4
x=2
So she would need 89+2=91
