Answer:
x=-1
Step-by-step explanation:
2x+3/4(4x+16)=7
2x+(3x12)=7--->distributive property
2x+3x+12=7
5x+12=7--->addition property
5x=-5--->subtraction peroperty
x= -1---?division property
4/5
1 - 2/10 = 8/10 = 4/5
San francisco
once you divide the distance by time then multiply the answer by the longest amount of time (aka 4)
San francisco = 2556
Minot = 1826
Phoenix = 2252
1.-3x+z - y
-3(-2)+4-(-4)
6+4+4
=14.
2.-2xz-3xy+4
-2(-2(4))-3(-2(-4))
-2(-8)-3(8)
16-24
= -8.
