Answer:
x < 7 1/3
Step-by-step explanation:
3x -5 <17
add 5 to each side
3x-5+5 <17+5
3x<22
divide by 3
3x/3 < 22/3
x < 22/3
x < 7 1/3
Answer:
An equation is
.
Step-by-step explanation:
☆Since since we're given the slope, all we need to do is find the y-intercept.
☆The slope-intercept formula is: y = mx + b.
☆We are going to plug in according to the formula.
☆We have everything we need, so now we put it together.
Answer:
1. 5
2. 5
3. -3
4.y= -1
5. 5
Step-by-step explanation:
1.)x- 2y= -25 ; y=3x
x-2(3x)=(-25)
x-6x=(-25) ; -5x=(-25) ; x=5
2.) 5x+3y =40; x=y
8y=40; y=5
3.) 4x-3y= -27; x=3y
4(3y)-3y= -27; 12y-3y=-27; 9y=-27; y=-3
4.)x-y=9; x=-8y; -8y-y=9; -9y=9; y=-1
5.) 2x+2y=30; y=2x ; 2x+2(2x)=30; 6x=30; x=5
Answer:
Step-by-step explanation:
71.28
12 : 14 = ? 21
6 : 7=42/2=21
12 and 14 can get divided into 2
2•6= 12
& 2•7=14
then take what you divided 12 & 14 into ( 6and7)
which gives you 42. what is half of 42 ? 21 is your answer
