so
6s+2l = 28
4s+5l= 37
eliminate 6s+2l=28 by dividing all numbers by 6
u get s= -1/3 l + 14/3
49-1/3l=14/3) + 5l =37
L=5
s= -1/3(5) + 14/3
s=3
l=5
According to my calculations. The answer to this question is 89
Answer:
C. 36.
Step-by-step explanation:
66 2/3 % = 2/3.
If the maximum number of laps is x then:
2/3 x = 24
3/2 * 2/3 x = 24 * 3/2
x = 72 /2
x = 36.
Answer:
7k - 7
Step-by-step explanation:
-k - (-8k + 7)
= -k + 8k - 7
= 8k - k - 7
= 7k - 7
D=deana's age
b=bernice's age
sum is 48
b+d=48
8 years from now, dena will be 3 times bernice age
d+8=3(b+8)
ok we gots
d+b=48
d+8=3(b+8)
d+b=48
minus b from both sides
d=48-b
subsitute 48-b into the other equation for d
d+8=3(b+8)
48-b+8=3(b+8)
56-b=3b+24
add b to both sides
56=4b+24
minus 24 both sides
32=4b
divide both sides by 4
8=b
bernice is 8 years old
