Answer:
20
Step-by-step explanation:
1/2(a+b)=180
1/2(6+12)=18
1/2(18)=180
9/9=180/9
=20
Answer:
The exponent is 2, so the degree is 2
Step-by-step explanation:
60% of original price X = $180
60/100 × X = $180
60X/100= $180( cross multiply)
60X= 18000
X= 18000÷60
X= $300
The equation of a line is y = mx + b
We know there is a b because the y intercept is not zero, so the first choice is wrong. We also know the last choice is wrong because this problem definitely has a slope (m).
The slope of the line of best fit seems to be closest to 3.25, meaning it goes up about that much for every one unit it goes to the right.
The second choice is correct.
The solution set of 3x+5=x+2 is x=-1. This is because you want to get the variables on one side and the numbers on the other. you subtract x on both sides and subtract 5 on both sides. your equation then becomes 3x=-3. you then divide 3 on both sides and you get your answer of x=-1.
