The car can travel 1120 miles because 20 times 56 equals 1120
Answer:
8 is the answer
Step-by-step explanation:
the equation is r = C/2*3.14
2*3.14=6.28
Because your C is 50 you do 50/6.28 and when you do that you get 7.962 (rounded) and then we round for the whole # so 8.
The answer would be A because you would take all of your answers and 1 by 1 multiply it by0.35 and it will give you the answer of $330.43
4x -3y + z = -10...............(1)
2x +y + 3z = 0...............(2)
-x +2y - 5z = 17...............(3)
First we multiply 3*(2) and add it to (1)
6x +3y +9z =0..................+(1)..................> 10x + 10z = -10......(4)
Then we multiply -2*(2) and add it to (3)
-4x -2y -6z =0 ...................+(3)................> -5x -11z = 17...........(5)
Multiply 2*(5) and add it to (4)
-10x -22z = 34...................+(4).................> -12 z = 24 ..............>>> z = -2
Substitute z in (4)............> 10x +10(-2) = -10.............................>>> x = 1
Substitute x and z in (2).....> 2(1) +y + 3(-2) = 0..................>>> y = 4
Solution (x,y,z) = (1,4,-2)
Answer: 115
Step-by-step explanation: because Laura exercises 150 minuets in all and Alicia exercises 265 in all. so you subtract
265-150 and you get 115
