Like a first step bc. there is a denominator this will be more usefully eliminate it so what you can make it multiplied both sides by 2
- so will get
-2/2x +2*3/2 = 2(-4x+7)/2
(-2x +6)/2 = 2(-4x+7)/2 common denominator the 2 so make the numerators equal and solve for x
-2x+6=-8x+14
6x=8
hope helped
Answer:
x=4 and y=1
Step-by-step explanation:
Equation 1) 3x+8y=20
Equation 2) 5x+3y=23
Equation 1) 5(3x+8y=20 )
Equation 2) 3(5x+3y=23)
15x+40y=100
15x+9y=69
(Take away 40y from 9y and 100 from 69)
31y = 31
y=1
Substitute y=1 into equation 1)
3x+8=20
(Take away 8 from both sides)
3x=12
(Divide by 3)
x=4
-5x^3 + 2x^2 + 1
a coefficient is the number that is multiplied by the variable.For instance, the coefficient of 2x is 2....because 2 (the number) is multiplied by the variable x.
so in ur problem....there are 2 coefficients..-5 and 2.
** the number 1 is not a coefficient, it is a constant...a " loner " with no variables (letters) attached.
** and if u have just the letter...such as n, the coefficient to that is 1 but the one is just not written...it is actually 1n.
okay...I am gonna shut up now :)
Answer:2.81
Step-by-step explanation:
First you subtract the per week (220) from your budget (361)
You get 141
You now divide 141 by 50.15
You come out to 2.81
This means you can drive up to 2.81 miles but no more
