Answer: x=-7
Step-by-step explanation:
1. distribute the 2 to (3x-12) >>>> 8x+6x-24=-122
2. add 8x and 6x to get 14x >>>> 14x-24=-122
3. add 24 to both sides>>>> 14x=-98
4. divide 14 by both sides>>>x=-7
Answer: 55
Step-by-step explanation: There is one simple theorem we need to know in order to solve for this.
Triangle Angle-Sum Property: All three angles interior angles of a triangle add up to 180°.
Thus, we could label the points A, B, and C, and set up an algebraic expression.
Let A = 27, B = 98, and C = x.
A + B + C = 180°.
Substituting A, B, and C we get:
27 + 98 + x = 180°.
Adding, we get:
125 + x = 180°
Subtracting 125 by 180, we get:
x = 55°
Thus, the angle X is 55°.
We could have simply solved this by just doing 180 - 98 - 27 = 55 in the first place, but I wanted to show you how I got such results.
Since its out of 15 marbles all together and all you need to find is the probability of 3 blue marbles you would have to divide 3 by 15. The outcome would be 0.2 or in your case... B. - 0.20
Answer:
2 x+3 y and 3 x+ 2 y
Step-by-step explanation:
Let x represents the number of roast beef and y represents the number of turkey sandwiches.
Let r and t represent cost of the roast beef and sandwich.
Platter A:
Platter A has 2 roast beef and 3 turkey sandwiches. So, equation is 2 x+3 y.
Total cost of the platter = 2 r x+3 t y
Platter B:
Platter B has 3 roast beef and 2 turkey sandwiches. So, equation is 3 x+2 y.
Total cost of the platter = 3 r x+2 t y
So, the two equations are 2 x+3 y and 3 x+ 2 y.
