Answer:
Step-by-step explanation:
3x+(x-2)=10
4x=12
x=12/4=3
y=x-2=3-2=1
so, x=3 and y=1
Answer: (3;1)
<span>The equation that can be used is 90-10y=5x. In order to get this answer, you first start with figuring out how many miles total were hiked for each trail. The 5-mile mountain trail total would be equal to 5x and the 10-mile canal trail total would be 10y. Adding both of these totals together would give you 90 miles and an equation of 5x+10y=90. All you do now is rearrange the equation by subtracting 10y from each side and you get 90-10y=5x.</span>
Answer:
7×7=49
Step-by-step explanation:
Is means equals and times means multiply
7×7=49
True
7−7=49
7-7=0 False
7+7=49
7+7 =14 False
49÷7=7
True but this is not the equation described above
7×7=48
49False
If it’s all 3 being chosen it’s 1/7 X 1/7 X 1/7 which is .002915 which would be a .29%
