<span>2x-3y=-8 /* 2 -------> 4x -6y = -16
9x+2y=-5 /*3 --------> 27x +6y = -15
</span>4x -6y = -16
<span>27x +6y = -15
</span>
31x = -31
x = -1
2x-3y=-8
2*(-1) - 3y = -8
-2 - 3y = -8
-3y = -6
y = 2
x= -1, y = 2
(-1,2)
Check:
2(-1)-3*2=-8 -----> - 2 - 6 = -8 ----> -8 = -8 True
9x+2y=-5 -------> 9(-1) +2*2 = -5 ------> - 5 = -5 True
So, solution is (-1,2).
Answer:
Step-by-step explanation:
Given
Kano = 45;
Kwara = 410;
Ogun = 105;
Ondo = 126;
Oyo = 154
Total Distribution = 840
Required
Determine the angle subtended by Ondo (in a pie chart)
The general formula to calculate subtended angle in a Pie chart is;
In this case of Ondo
Frequency = 126
Total Frequency = Total Distribution = 840
Substitute these values in the given formula;
<em>Hence, the angle subtended by Ondo is 54</em>
Answer:
A,B,E
Step-by-step explanation:
Divide both sides by 8.2
<em><u>Correct choices:</u></em>
<em>w ≤ 3.6 </em>
The arrow points left.
There is a closed circle at 3.6.
Answer: there are no numbers here there only variables so x=1 i think but i am not sure
Step-by-step explanation:
The question asks per week. So 1.5 cups times 7 days is 10.5 cups.
The pipe leaks 10.5 cups every week.
