At a track meet, the 3 members of a relay race ran a total distance of 3/8 of a mile. if each runner ran the same distance. how

Lemur [1.5K]

Answer:

.125 of a mile

Step-by-step explanation:

If the total distance was 3/8 of a mile and there were 3 runners, then each runner ran ___________________.

Change the 3/8 to a decimal

3/8 = 0.375 of a mile

Since there were 3 runners divide the total distance by 3

0.375/3 = 0.125

Each runner ran 1/8 of a mile or 0.125 of a mile.

The system of equations above is graphed below. Find the solution to the system.

Oksana_A [137]

Option D: $x=3,y=-2$ is the solution to the system of equations.

Explanation:

Given that the equations are $4x+y=10$ and $2x+y=4$

We need to determine the solution of the system of equations.

The solution can be determined by solving the two equations.

Let us solve the system of equations using substitution method.

Consider the equation $4x+y=10$ , the value of y is given by

$y=10-4x$

Substituting the value of $y=10-4x$ in the equation $2x+y=4$ , we get,

$2x+(10-4x)=4$

Simplifying, we get,

$2x+10-4x=4$

$-2x+10=4$

$-2x=-6$

$x=3$

Substituting the value of $x=3$ in $4x+y=10$ , we get,

$4(3)+y=10$

$12+y=10$

$y=-2$

Thus, the solution to the system of equations is $x=3,y=-2$

Hence, Option D is the correct answer.

Hey I was just wondering if anyone can give me a better explanation on how to work with Negative numbers and and fractions when

Soloha48 [4]

Answer:

see explanation

Step-by-step explanation:

Given

$\frac{6(2a-4c)-6(6a-4b)+3(4b-8c)}{4}$

Distribute the 3 parenthesis on the numerator

= $\frac{12a-24c-36a+24b+12b-24c}{4}$

Collect like terms on the numerator

= $\frac{-24a+36b-48c}{4}$

Divide each of the terms on the numerator by 4

= $\frac{-24a}{4}$ + $\frac{36b}{4}$ + $\frac{-48c}{4}$

= - 6a + 9b - 12c ← factor out - 3 from each term

= - 3(2a - 3b + 4c)

Compare with

X(2a + Bb + Cc) to obtain

X = - 3, B = - 3, C = 4

PLEASE HELP ASAP PLZZ I WILL GIVE BRAINLIEST In order to increase the circumference of a circle from 12pi cm to 18pi cm, by how

pshichka [43]

Answer:

This is because the diameter of the smaller circle is 12pi/pi which is 12, and the diameter of the bigger one is 18pi/pi which is 18. 12 + 6 = 18, so the diameter increases by 6.

On a workday the average decibel level of a busy street is 69 db, with 139 cars passing a given point every minute. if the numbe

Vlad1618 [11]

Decibel is directly proportional to number of cars passing the point. That is,

69 db ----- 139 cars
x db ----- 17 cars

x = number of cars passing the point per minute on a weekend.

Then,
x= (69*17)/139 = 8.43 db ≈ 8 db
