Plug in 3 for "y":
7x + 2y = 48
7x + 2(3) = 48
2*3 = 6
7x + 6 = 48
Then, you have to subtract 6 to both sides..
7x = 42
Divide 7 to both sides and the your answer would be 6
Answer:
The answer is 83/4
Step-by-step explanation:
5 1/4+15.5
21/4+15.5
Taking LCM
21/4+15.5*4/1*4
21/4+62/4
83/4
Answer:
6^-8 or 1/ 6^8
Step-by-step explanation:
When there is a fraction with the same base, then subtract the exponent of the denominator from the exponent of the numerator.
6^-3 / 6^5 = 6^(-3-5) = 6^-8
Answer:
Step 1; it should be m∠x + m∠y + m∠z = 180 degrees (sum of angles of a triangle)
Step-by-step explanation:
The answer is self-explanatory. The sum of interior angles of a triangle is 180°.
