The correct answer for that is y=4
4a - 2b = 10
a + c = 3 so a = 3 - c and c = 3 - a
4(3 - c) - 2b = 10
12 - 4c - 2b = 10
-4c -2b = -2
2c - b = 1
That’s all I have so far :/
Answer:
x = 12.2
Step-by-step explanation:
sin theta = opp / hypotenuse
sin 55 = 10 /x
Multiply each side by x
x sin 55 = 10
Divide each side by sin 55
x = 10 / sin 55
x =12.20774589
Rounding to the nearest tenth
x = 12.2
Tip when answering this type of question: When the question does not provide you with an illustration, draw it according to the information given and solve. :)
Answer;
X=6
Explanation
1. Find what’s on both sides
6x -9. And 4x +3
2. Turn into equation to do that you need to put a equal sign in between
6x-9=4x+3
3. Solve
6x-9=4x+3
-4x+9 -4x +9
__________
2x=12
— —
2 2
X=6
Explanation for solving you want your numbers on one side and x’s on the other so for positive numbers I subtract and for negative numbers you add, u only have to move one x and 1 number after simplified. Then you take the number (if one ) next to x and divide it on both sides since it’s multiplication. Then you get your answer
