Can someone do these algebra (1) math problems?

Question

I can't get these last 3... all of them are multiple choice and you are SOLVING FOR X IN ALL THREE OF THESE PROBLEMS.


1. b + ax = 12

what is the solution?
a. x = 12b/a
b. x = 12 - (b/a)
c. x = 12b - a
d. x = (12 - b)/a

2. ax - c = d

what is the solution?
a. x = 12 - b/a
b. x = 12 - ab
c. x = (d + c)/a
d. x = (d + a)/c

3. bx = h

what is the solution?
a. x = bh
b. x = b/h
c. x = b - h
d. x = h - b

Answer 1

d,c
3 is incorrect, x=h/b.

Answer 2

For all these, you want to undo all the mathematical operations to isolate x.

1. b + ax = 12
b - b + ax = 12 - b
ax/a = (12-b)/a
x = (12-b)/a (Answer d)

what is the solution?
a. x = 12b/a
b. x = 12 - (b/a)
c. x = 12b - a
d. x = (12 - b)/a

2. ax - c = d
ax - c + c = d + c
ax/a = (d + c)/a
x = (d + c)/a (Answer c!)

what is the solution?
a. x = 12 - b/a
b. x = 12 - ab
c. x = (d + c)/a
d. x = (d + a)/c

3. bx = h
bx/b = h/b
x = h/b (no answer given is correct)

what is the solution?
a. x = bh
b. x = b/h
c. x = b - h
d. x = h - b

Answer 3

particular your paintings is nice good interest! we could go over what you probably did ok? 4y+20=5x you subtract 20 from the two sides so 4y = 5x - 20 then you relatively divided by utilising 4 y = (5/4)x - (20/4) it is comparable to y = (5/4)x - 5 (that's the slope intercept sort) A slope intercept sort is y = mx+b the place m = slope b = y intercept Now you % to locate the y and x intercept it is amazingly common. All you're able to do to locate the y intercept is desperate x = 0 and remedy for y which for this reason is y = (5/4)(0) - 5 y = -5 (y intercept) and of path all you're able to do to locate the x intercept is desperate y = 0 and remedy for x which for this reason is 0 = (5/4)x - 5 upload 5 to the two sides so 5 = (5/4)x divide the two sides by utilising (5/4) so 5/(5/4) = x it is comparable to 20/5 = x = 4 (x intercept) Yea the respond for y and x intercept could be in fractions it is positive! wish it facilitates somewhat.

Answer 4

1. D

If a= 4
b= 4
x= 2

4 + 4(2) = 12

x = (12 - 4)/4
= 2
The same!

2. C

3. B, u write wrong it must be x = h/b

Answer 5

1. d b + ax=12 ax = 12-b x = (12-b)/a

2, c ax=d+c x=(d+c)/a

3. I got x = h/b

good luck!

Answer 6

1)b+ax=12
ax=12-b
x=(12-b)/a
Answer:d

2)ax-c=d
ax=d+c
x=(d+c)/a
Answer:c

3)bx=h
x=h/b
Answer: None of the answers are correct!!

Answer 7

1. b+ax=12
ax=12-b
x=(12-b)/a

Answer=b

2. ax-c=d
ax=d+c
x=(d+c)/a

Answer=c

3. bx=h
x=h/b

Answer= i think b is incorrectly written.It's inverted.

Answer 8

Yes. I can solve those math problems.
