Answer:

D is equivalent to the expression.

Step-by-step explanation:

The expression that is given equals 2.8, or 2.8x.

A. This expression equals 1.6x, and 1.6x is not equivalent to 2.8x

B. 0.3x + 3.1 = 3.4x. This doesn't have the answer of 2.8x.

C. 1.3 - 0.3x = 1 or x.

D. 3.1 - 0.3x = 2.8x. D is the answer.

It takes omar four minutes to eat eight carrots sticks. how long does it take him to eat one ?
astra-53 [7]
It takes Omar 30 seconds to eat one considering he ate 8 in 4 minutes ...

If we really wanted to we could turn this into the fraction 8/4
8 being the amount of carrot sticks he ate and 4 being the time it took
now all u have to do is simplify that turns into 2/1 and since the 1 is one minute and her can eat 2 in one minute we can safely say he eats 1 carrot stick every 30 seconds 

:) hope this helps!!

Evelyn can run 3 miles in 40 minutes. Which equation can be solved to find m, the number of miles Evelyn can run in 60 minutes?
inna [77]

Answer:

m= 4.5 miles

Step-by-step explanation:

Let the number of miles Evelyn can run be m and can be modeled by the equation below

m= kx

Where x Is the Minutes

When m= 3

x= 40

3= k40

k= 3/40

If x= 60

m=3/40(60)

m = (60*3)/40

m= 180/40

m= 4.5 miles

1. 90c : $4.50<br> 2. 80cm : 1.2m
horrorfan [7]

Answer:

see explanation

Step-by-step explanation:

Before simplifying the ratios we require them to have the same units.

(1)

$4.50 = 450c, thus

90c : $4.50

= 90 : 450 ← divide both parts by 10

= 9 : 45 ← divide both parts by 9

= 1 : 5

(2)

1.2 m = 1.2 × 100 = 120 cm, thus

80 cm : 1.2 m

= 80 : 120 ← divide both parts by 10

= 8 : 12 ← divide both parts by 4

= 2 : 3
