Step-by-step explanation:
Let
x -----> Kevin’s savings accounts amount at the beginning of the month
Remember that
we know that
The amount in Kevin’s account at the end of the month is equal at the amount at the beginning of the month multiplied by 1.04
so
Answer:
70 miles driven this month
Step-by-step explanation:
This is an algebra problem and denote A number of miles driven this month as x to be found
Answer:
70 miles were driven this month
Step-by-step explanation:
suppose 100 miles were driven last month
30%= 30/100*100=30 miles
30% decreasewould be 100-30= 70 miles
1. Determine the cost to produce 500 helmets.
Answer:
Cost to produce 500 helmets will be $9000.
Step-by-step explanation:
Expression that represents the cost of the bicycle helmets is given as
C = 3000 + 12x
where x = number of helmets produced.
1. Cost of production of 500 helmets can be calculated by putting x = 500 in the expression.
C = 3000 + 12×500
= 3000 + 6000
= $9000
Therefore, cost to produce 500 helmets will be $9000.
Answer:
$9000
Step-by-step explanation:
3000+12x
x = 500
3000 + (12*500)
3000+6000
$9000
1/4 * 3/4 = 3 /16 of a circle
Answer:
x=-5 x=-4
Step-by-step explanation:
y=x^2 + 9x + 20
We need to factor the equation
What 2 numbers multiply to 20 and add to 9
4*5 = 20
4+5 =9
y=(x+5) (x+4)
To find the zero's we set the equation equal to zero
0= (x+5) (x+4)
Using the zero product property
x+5 = 0 x+4=0
x=-5 x=-4
Answer:
zero
Step-by-step explanation:
The lines are parallel ( they have the same slope)
the slope is 1/2 ( up 1 over 2)
The y intercept is different.
The lines will never intersect.
Therefore there are zero solutions
Answer: Zero
Step-by-step explanation: Since the lines are parallel, the two lines will never be able to meet.
