10x-7(3x+8)=-26x+4
first you have to isolate the variable
then you divide each side by factores that don't contain the vairable
for this problem if you follow those steps
X=4
-7(3x+8)=-36x+4
-11(3x+8)=-36x+4
Answer:
money saved by james = 30/2 = 15
equation used
money with James = 3/4 (money with sister)
x/2 + 30 =3/4( x + 30 )
Step-by-step explanation:
Let money saved by sister be x
given
James has saved half the amount of money as his sister has saved.
Money saved by James = x/2
Total money saved by both of them = x + x/2
If they both save 30 more
Then
money with sister = x + 30
money with james = x/2 + 30
given that If they both save 30 more, james will have saved 3/4 as much as her sister
thus,
money with james = 3/4 (money with sister)
x/2 + 30 =3/4( x + 30 )
=> 4(x+30*2) /2 = 3x+90
=> 2x + 120 = 3x + 90
=> 3x-2x = 120-90
=> x = 30
Thus,
money saved by james = 30/2 = 15
equation used
money with james = 3/4 (money with sister)
x/2 + 30 =3/4( x + 30 )
In Polynomials all the exponents of x-variable must be positive integers, then polynomials are:
<span>a) -x^5+7x-1/2x^2+9, the exponents of x's are: 5, 1, and 2
b) x^3-4x-3, the exponents of x's are: 3, and 1
f) x^4+x^3√7+2x^2-√3/2x+π, the exponents of x's are: 4, 3, 2, and 1
Not polynomials are:
</span><span>c) 4 / x^2-4x+3 = 4x^(-2)-4x+3, the exponents of x's are -2, and 1
d) x^4+5/x^3-√x+8=x^4+5x^(-3)-x^(1/2)+8, the exponents of x's are 4, -3, and 1/2
e) </span>|x|^2+4√x-2=<span>|x|^2+4x^(1/2)-2, the exponents of x's are 2 and 1/2</span>
Answer:
1/3
Steps:
The line rose 10 values (up) and went 30 values higher (to the right), so you divide 10/30 and end up with 1/3
