Answer:
60 divided by 20 is 3 so 30 times 3 is 90
Answer:
C. 200 h
Step-by-step explanation:
1250 / 50 = 25
25 * 8 = 200
f(x)=9-2x
--------------------
f(x)=25
9-2x=25
-9 -9
-2x=16
/-2 /-2
x = -8
---------------------
f(x)=-41
9-2x=-41
-9 -9
-2x=-50
/-2 /-2
x = 25
----------------------
f(x)=17
9-2x=17
-9 -9
-2x=8
/-2 /-2
x = -4
-----------------------
f(x)=-8
9-2x=-8
-9 -9
-2x=-17
/-2 /-2
x = -17/2
Answer:
x=71
Step-by-step explanation:
180-38= 142
142/2= 71
it looks like x and the blank space are the same size
Answer:
first, subtract 17 on both sides: x²+2x-16=0
this cannot be factored, so use the quadratic formula to solve for x:
b²-4ac=2²-4(10(-16)=4+64=68
√68=2√17
so x=(-2+2√17)/2 or x=(-2-2√17)/2
x=-1+√17 or x=-1-√17
