1) Seven less than twice a number, n, is 32.
ANS) B. 2n - 7 = 32
Answer:
a. 21 2/6
Step-by-step explanation:
5 2/6 multiplied by 4 is 21 2/6
Because we know that the number in between x+6 and 2x-3 is 18, we can solve for x by doing (x+6+2x-3)/2=18. this simplifies to 3x+3=36, or x=11.
Answer:
30°
Step-by-step explanation:
Let the measure of the missing angle be x°
Therefore, by interior angle sum postulate of a triangle:
x + 60° + 90° = 180°
x + 150° = 180°
x = 180° - 150°
x = 30°
Thus the measure of the missing angle is 30°.
