What is 5 1/3 subtracted by 2 4/5

Luda [366]

$\text {Hi! Let's Solve this Problem!}$

$\text {The First Step is to Convert all Mixed Numbers into Improper Fractions:}$

$\text {Multiply 5*5 and get 15. Now add 1 and get 16.}\\\text {5 1/3 = 16/3}$

$\text {Multiply 2*5 and get 10. Now add 4 and get 14.}\\\text {2 4/5 = 14/5}$

$\text {Your new Problem should be: 16/3-14/5}$

$\text {The Next Step is to Subtract:}$

$\text {16/3-14/5=}$

$\text {Your Answer would be:}$

$\fbox {38/15}$

$\text {Your Final Step is to Convert 38/15 into a Mixed Number:}$

$\text {38/15=}$

$\text {Your Final Answer would be:}$

$\fbox {2 8/15}$

$\text {Best of Luck!}$

PLEASE HELP!!!!!!!

Leno4ka [110]

Answer:

(a)

degree is 4

it is binomial

(b)

degree is 2

it is trinomial

(c)

degree is 3

it is monomial

Step-by-step explanation:

(a)

we are given function as

$f(x)=5x^4-8$

Degree:

we know that degree is highest exponent value

so, degree is 4

Number of terms:

we can see that there are two terms

so, it is binomial

(b)

we are given function as

$f(a)=4a^2-2a-16$

Degree:

we know that degree is highest exponent value

so, degree is 2

Number of terms:

we can see that there are three terms

so, it is trinomial

(c)

we are given function as

$f(m)=9m^3$

Degree:

we know that degree is highest exponent value

so, degree is 3

Number of terms:

we can see that there are one term

so, it is monomial

PLEASE HELP! I HAVE TWO QUESTIONS AND WILL GIVE 100PTS AND BRAINLIEST IF CORRECT!

Volgvan

Answer:

1) $283.50

2) 65.21 meters.

Step-by-step explanation:

Part 1)

We know that a spool of ribbon holds 6.75 meters.

A craft club buys 21 spools.

So, the total length of ribbon bought is:

$T=21(6.75)=141.75\text{ meters}$

Each meter costs $2. So, the total cost will be:

$141.75(2)=\$ 283.50$

Part 2)

A spool holds 6.75 meters.

We bought 21 of them, so that total length we have is 141.75 meters.

The club used 76.54 meters.

So, the amount of ribbon that is left is represented by:

$141.75-76.54$

Subtract:

$=65.21\text{ meters}$

So, 65.21 meters of ribbon will be left.
