6x -19 + 3x + 10 = 180
9x -9 = 180
9x = 189
x = 21
Hey John
Let's start solving #1
x/4 = 3.5/28
Cross multiply
(x)(28) = (3.5)(4)
28x = 14
Divide both sides by 28
28x/28 = 14/28
x = 1/2
Next, let's solve the second one

Simplifies to:

Cross multiply
(105x + 75)(5) = (28)(50x)
525x + 375 = 1400x
Subtract 1400x to both sides
525x + 375 - 1400x = 1400x - 1400x
-875x + 375 = 0
Then subtract 375 from both sides
-875x + 375 - 375 = 0 - 375
-875x = -375
To find x, divide both sides by -875
-875x/-875 = -375/-875
x = 3/7
Let me know if you have questions about the answer.
Best of luck with your studies!
<span>The answer two this question is C.
You can get this answer by multiplying the two polynomials and then simplifying. See the steps below:
(4x^2 - 5)(x + 3) ---> Now multiply the two parenthesis.
4x^3 - 5x + 12x^2 - 15 ---> Arrange the numbers by decreasing exponents.
4x^3 + 12x^2 - 5x - 15
No simplifying can be done since there are no like terms. </span>
Answer:
The equation is in standard form. You will have to convert it to slope intercept form, which is -0.125x + 3.75 = y
Step-by-step explanation:
s = x and a = y, therefore 0.5x + 4y = 15
0.5x + 4y = 15
0.5x + 4y = 15 first subtract 0.5x
4y = -0.5x + 15 then divide all by 4
y = -0.125x + 3.75 slope intercept form
Answer:
3,2 i think sorry if im wrong
