Answer:
Step-by-step explanation:
3x + 7 + 9x - 43 = 180
12x = 216
x = 18
m∠4 = 3(18) + 7 = 61°
m∠5 = 9(18) − 43 = 119°

Answer:
n=-10/3
Step-by-step explanation:
"Twice the difference of a number n and seven is equal to four less than the product of five and the number n" translates into 2(n-7) = 5n - 4. To solve, isolate the variable n.
2(n-7) = 5n - 4
2n - 14 = 5n - 4
2n - 10 = 5n
-10 = 3n
-10/3 = n

Answer:
Mp=24
Step-by-step explanation:
From expression 2x-4, we solve for x.
Then we have: x=4/2 → x=2
Replace x=2 in Mp=5x-34
Solve for Mp:
Mp=5x2-34
Mp=10-34
Mp=-24
