Answer:
Advanced tickets=30 Day =20
Step-by-step explanation:
Put them into equations:
x=advanced
y=day
x+y=50
25x+15y=1050
to make it simpler re-arrange x+y=50
x=50-y
Then substitute into 25x+15y=1050
25(50-y)+15y=1050
Expand
1250-25y+15y=1050
Rearrange
25y-15y=1250-1050
Work the above out
10y=200
y=20
and then
20+x=50
meaning....
x=30
showing Advanced tickets=30 Day =20
Answer:
12). LM = 37.1 units
13). c = 4.6 mi
Step-by-step explanation:
12). LM² = 23² + 20² - 2(23)(20)cos(119)°
LM² = 529 + 400 - 920cos(119)°
LM² = 929 - 920cos(119)°
LM = 
= 
= 37.08
≈ 37.1 units
13). c² = 5.4² + 3.6² - 2(5.4)(3.6)cos(58)°
c² = 29.16 + 12.96 - 38.88cos(58)°
c² = 42.12 - 38.88cos(58)°
c = 
c = 
c = 4.6386
c ≈ 4.6 mi
Answer:
b=0.25×80
or
b=1/4×80
Step-by-step explanation:
We know that bike equals 25%, so we just need to find 25% of 80.
b=0.25×80.
(x+1)(x+2)
this is what i got hope it helps
It weighed 5 ounces. Subtract the first ounce from the total price then divide the remaining money by 0.21 to get four plus the first ounce.
