Answer:
x < 1 and x <u>></u> -2
Step-by-step explanation:
5x - 1 < 4 and 3x + 5 <u>></u> x + 1
Step 1.) Transfer the -1 over by the 4 by adding it because you use the opposite symple when its transfered.
5x < 5 and 3x + 5 <u>></u> x + 1
Step 2.) Divide 5 by 5 to get the variable alone
x < 1 and 3x + 5 <u>></u> x + 1
Step 3.) Subtract x from 3x which gives 2x and subtract 5 from 1 which gives -4
x < 1 and 2x <u>></u> -4
Srep 5.) Divide -4 by 2 to get the variable alone and you get -2
x < 1 and x <u>></u> -2
The answer is going to be B)1 and 3/4 miles because when you subtract 2 1/8-3/8 it = 1.75 75 as a fraction is 3/4 and your whole number is one
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
