Answer:
5x = 14
Step-by-step explanation:
If 5 yards of fabric is $14 you need an equation that would solve how much 1 yard of fabric costs. You can say 5x = 14 or x = 2.8 which means that one yard of fabric (1x or just x) is $2.80.
Answer:
B. 2 3/5
Step-by-step explanation:
how i would solve this expression is start out by converting "4 1/3" into an improper fraction.
4 1/3 is equivalent to 13/3
next to find out how much water melissa used we have to multiply 3/5 by our improper fraction giving us this expression:
13/3 x 3/5
solving a fraction is simple, multiply the numerator by numerator,
and denominator by denominator.
so, we will end up with
39/15 or simplified to 2 3/5
hope this helps :D
Answer:
Solution given:
y=-1/2 x²
for
f(x)=-1/2 x².
differentiating each term with respect to x
f'(x)=-x
when
x=-4
f'(-4)=4>0 increasing
when
x=-2
f'(-2)=2 >0 increasing
when x=0
f'(0)=0 stationary point.
other points are decreasing
so
largest interval of increasing is
A.X<-2
Answer:
Since The graph of linear equation 3x + 2y = 16 cuts y-axis
So
x = 0
The required point is (0,8)
Step-by-step explanation:
You can divide 100 by 4 to find out how many lunches you can buy
or multiply 4 by the number of lunches you have had
100 - that number^=money remaining
