Well, for this question we can start off by making an equation
(6.4)2
This problem is quite simple actually so we will just multiply 6.4*2
6.4*2=12.8 miles
Answer:
5.25
Step-by-step explanation:
15/10=1.5
9*1.5=13.5
13.5-3=10.5
10.5/2=5.25
Answer:12
Step-by-step explanation: do you mean g+7-4 if you do then first you subtract 7 that gives us g-4=8 then you add 4 and that’s g=12
First set up equation
x times y=xy
so
xy=-29
and
x+y=1
subtract x from both sides
y=1-x
subsitute 1-x for y in first equation
x(1-x)=-29
distribute
x-x^2=-29
add x^2 to both sides
x=-29+x^2
subtract x from both sides
0=x^2-x-29
so we can use the quadratic formula to solve for x if the equation=0 and it is in ax^2+bx+c form so
if
ax+bx+c=0 then x=

that means x=

or x=

so
x^2-x-29
a=1
b=-1
c=-29

=
![\frac{ +1-\sqrt{1^2-(-116)} }{2(1)}=\frac{ +1-\sqrt{1^2+116} }{2}=\frac{ +1-\sqrt{117} }{2}= \frac{1-10.816653826392}{2} = [tex] \frac{-9.816653826392}{2}= -4.908326913196](https://tex.z-dn.net/?f=%5Cfrac%7B%20%2B1-%5Csqrt%7B1%5E2-%28-116%29%7D%20%7D%7B2%281%29%7D%3D%5Cfrac%7B%20%2B1-%5Csqrt%7B1%5E2%2B116%7D%20%7D%7B2%7D%3D%5Cfrac%7B%20%2B1-%5Csqrt%7B117%7D%20%7D%7B2%7D%3D%20%5Cfrac%7B1-10.816653826392%7D%7B2%7D%20%3D%20%5Btex%5D%20%5Cfrac%7B-9.816653826392%7D%7B2%7D%3D%20-4.908326913196)
the second number is

the two numbers are
5.908326913196 and
-4.908326913196
