Answer:
hotdog $1, and hamburger $2
Step-by-step explanation:
D-is hot dogs, H-hamburgers
7D +4H = 15
4D +7H = 18
we got 2 equations with 2 unknown so we can solve
7D +4H = 15 multiply by 7
4D +7H = 18 multiply by -4
49D +28H = 105
-16D -28H = -72 add the two equations
33D= 33 so D=$1
go back to the first equation:
7*1 +4H =15 gives us 4H = 15-7; 4H = 8 so H= $2
Answer:
See below in bold.
Step-by-step explanation:
(-3)^3(2^6)/(-3)^5(2)^2
= (-3)^(3-5)*(2^4)
= 2^4 / (-3)^2 so a = 4 and b = 2.
2^4 / (-3)^2
= 16/9 so c = 16 and d = 9.
You can use this formula: <span>vf^2=0+2(9.8)(M)
solve it out like so:
vf^2=0+2(9.8)(180)
vf^2=2(1764)
vf^2=3528
now, square both sides to cancel out the power of 2. you are left with:
about 59.4 m/s</span>
Answer:
Equation: 25.81 = 6.55 + 3x
One Bag of Lemons: $6.42
Three Bags of Lemons: 19.26
Step-by-step explanation:
25.81 = 6.55 + 3x
-6.55 -6.55
19.26 = 3x
/3 /3
6.42 = x
Thus, he/she payed $6.42 for each bag of lemons and $19.26 for all three bags of lemons combined.
