A. d=45t
b. 112.5 miles. 112.5=45•2.5
Step-by-step explanation:
4x+2x+x+9x=16x
16x=2+5+4=11
x=11
Answer:
X=0 the temperatures is 40
Step-by-step explanation:
y=1/4x +40
x=0
y=1/4*0+40
y=0+40
y=40
4-7x= 39
Subtract 4 from both sides
-7x= 35
Divide both sides by -7
x= -5
The value of x+1= (-5)+1= -4.
