Answer:
Yes
Step-by-step explanation:
A relationship is proportional when both "sides" increase by the same amount each time. The x values increase by 3 each time, and the y values increase by 5 each time.
Answer:
since opp. angles of a parallelogram is equal.
therefore,
let the angle be x
thus,
x+x=140
2x=140
x=70°
co interior angles are supplimentary,
thus,
x+y=180
y=180-70
y=110°
opp. angles are equal thus,
fourth angle =110°
1st angle=70
2nd angle=70
3rd angle =110°
Step-by-step explanation:
Ok so start with the proportion 12/2 (the number of quizzes per 2 weeks) and set it equal to 18/X (X being the number of weeks that will equal 18 quizzes) after that cross multiply to get 12X=36. divide by 12 to get X=3 weeks
Answer:
(X+4)(x-11)
X= -4
X = 11
Step-by-step explanation:
x^2-7x - 34=10
x^2 -7x -34 -10 =0
x^2 - 7x - 44 = 0
The number in the middle is -7 and the other number is -44
Find two numbers that when multiply = -44 and when added= -7
4 * -11 = -44 and 4 + -11 = -7
Answer: (x+4)(x-11)
x + 4 = 0
x = -4 and
x -11 = 0
x = 11
