Twice a number decreased by eight is less than five times the number increased by ten.

Answers

Answer 1

Answer: twice a number (2 times x) dcreased by 8 (minus 8) is less than (<) 5 times the number (5 times x) increses by 10 ( plus 10)

2x-8<5x+10
subtract 2x from both sides
-8<3x+10
subtract 10 from both sides
-18<3x
divide both sides by 3
-6<x

the number is any number bigger than -6

Answer 2

Answer: x*8-5*x+10 that's the equation...

the equation formula of the circle is (x-h)^2 + (y-k)^2 = r^2
where (h,k) the point of the center of the circle
and (r) is the radius of the circle
so if the center of the circle = (-2,-4)
by subs. in the formula we get (x-(-2))^2 + (y-(-4))^2 = r^2
then the equation will be (x+2)^2 + (y+4)^2 = r^2
now we want to define the radius of the circle r
since point (3,8) lay on the circle so we can
then subs. in the equation to get the radius
(x+2)^2 +(y+4)^2 = r^2
(3+2)^2 +(8+4)^2 = r^2
25 + 144 = r^2
r^2 = 169
r= 13
the radius of the circle is 13
so by subs in the equation we get
(x+2)^2 + (y+4)^2 = 169
so it is the first answer in the choices

C) 28 feet
D) 40 feet

Answers

Hi there. We know that the formula is P=2(l+w). So, let's solve for x :), l=P/2-w=52/2-12=14 ft. So, your answer would be B) 14 feet.

A baker is calculating the charge for two types of cookies. What formula tells the cost, in dollars, if chocolate chip cookies are $1.50/dozen and lemon frosteds are $2.50/dozen? Let c = number of dozens of chocolate chip cookies; L= number of dozens of lemon frosteds; T= total charge

Answers

c=1.50 * 12 = 18.00$
L=2.50 * 12 = 30.00$
18.00 + 30.00 = 48.00
T=48.00$

Find the probability. Round to nearest tenth.

Answers

Answer:

Probability: (About) 0.8

Step-by-step explanation:

~ Provided that point X is randomly plotted on the line segment JM, we must calulculate the probability with which it lands on KM the first time ( implied ) ~

1. We know that the line segment JM, by the Partition Postulate ⇒ JK + KL + LM. With that being said JM = 3 + 7 + 4 = 14 units

2. Now line segment KM, by the Partition Postulate ⇒ KL + LM. With the assigned values, we can tell that KM = 7 + 4 = 11 units

3. If we were to determine the porbability that X lands on the line segment KM, considering the first try it would be KM/JM ⇒ Probability: 11/14
