<span>-3x - 8y = 10
-3*2 - 8y = 10
-6 - 8y = 10
8y = -6 - 10
8y = -16
y = -16/8
y = -2</span>
2x+15+x+20+30+25=180
3x+90=180
x=90/3
x=30

The smallest angle is 50
Answer:
Step-by-step explanation:
Given
Base:
Required
Determine the volume (in litres)
First, we need to calculate the area;
Base on the parameters given, we have:
So:
Answer:
3rd graph
Step-by-step explanation:
3m ≥ 21 whenever you see '≤ or ≥' then you know the circle must be filled
divide each side by 3 to isolate 'm':
m ≥ 7 This inequality, when graphed, should have a closed circle on the number 7 and the shading would be to the right because the symbol is indicates all values "greater than" 7
