Answer: the number of roses sold is 69 while number of tulips is 37
Step-by-step explanation:
Let x represent the number of roses that the flower shop sold.
Let y represent the number of tulips that the flower shop sold.
The number of roses sold was 5 less than twice the number of tulips sold. This means that
x = 2y - 5 - - -- -- - - - - - ;1
If the shop sold 106 flowers in total, it means that
x + y = 106
Substituting x = 106 - y into equation 1, it becomes
106 - y = 2y - 5
3y = 106 + 5 = 111
y = 111/3 = 37
x = 106 - y = 106 - 37
x = 69
Answer:
C: 4
Step-by-step explanation:
You call the number x. Then you do (x-7) * 3= -9.
3x-21=-9
3x=12
x=4
Lets take it in order:
1) 90 deg because the angle right next to it is a right angle
2) 128 deg becasue of the angle directly across from it
3) x = 180 - 128 = 52 deg
4) 180 = 90 + 52 + x so x = 180 - 90 - 52 = 38
5) 180 = 38 + x so x = 180 - 38 = 142
6) Same as 4
7) Same as 5
