Answer:
The angle of A is 80°
Step-by-step explanation:
Given that angle A lies on a straight line which is 180°. So in order to find A, you have to substract 100° from 180° :
∠A + 100° = 180°
∠A = 180° - 100°
∠A = 80°

Answer:
the price for one pretzel was $1.75
Step-by-step explanation:
d for drinks
p for pretzel
3d + 3p = 9
3d = 9 -3p
d = 3 - p
replace d = 3 - 9 into 4d + 2p = 8.5
4d + 2p = 8.5
4(3 - p) + 2p = 8.5
12 - 4p + 2p = 8.5
-2p = 8.5 - 12
-2p = -3.5
p = 1.75
Answer:
A=60 inches by 72 inches
B=increased 600%
Step-by-step explanation:
Scale is 6 times bigger, so 12*6=72
A=60 inches by 72 inches
First painting perimeter: 10+10+12+12=44 inches
Second painting perimeter: 60+60+72+72=264 inches
264/44*100%=600%
Subtract 25 and 10 which gives you 15
subtract 5/8 and 1/8 since they have common denominators.
You get 15 1/2 when you simplify 15 4/8 in which 4/8 is the same thing as 1/2.
