and since we know now what "x", let's use that in either equation, say the first equation,
another way to do it is by "elimination", depending on the equations, one way may work quicker than the other, in this case, substitution was the simpler one, because the first equation is already solved for "y", so we just grabbed it and plugged it in the 2nd equation.
Answer:
X = 
, or X = 3.6
Step-by-step explanation:
For this problem we must isolate x
1.03x+3.97x-5=13 | Add 5 to both sides
1.03x+3.97x=18 | Add the x's
5x=18 | Now divide both sides by 5
x=, x=3.6
The options are;
<span>a)4x+12
b)8x+24
c)2x^4+24
d)4x^2+24x+35

dimensions of the photograph
length - 7 inch
width - 5 inch
dimensions of the photo frame is 2x larger than both width and length
length - 7 + 2x
width - 5 + 2x
the perimeter is sum of all 4 sides
Perimeter = 2(7 + 2x) + 2(5 + 2x)
= 14 + 4x + 10 +4x
= 24 + 8x
correct answer is b
If I am correct the answer is 1.
You can do multiply 3 by 6/8 which will give you 2 1/4 or if in a decimal 2.25.
Then do 3 by -1/2 which will give you -1 1/2 and in decimal its -1.5.
You continue with the equation, 2.25 -1.5 = 0.75 + 0.25 = 1
Add them all together and you get 1...!
Hope this Helps :)
