Answer:

Your answer should be -13/15 < -5/6

Step-by-step explanation:

You would want to get the fractions to common denominators which in this case is 30.

So -13/15 = -26/30 (13*2 = 26, 15*2 = 30.)

And -5/6 = -25/30 (5*5 =25, 6*5 = 30.)

Since the fractions are also negative, the number closest to 0 would be the greater fraction. Which in this case would be -5/6. I hope this helps you! :)

Adam cut a piece of string 42 inches long into 2 pieces. The ratio of the length of the 2 peices is 3:4, what is the length, to

jek_recluse [69]

Answer:

Shorter piece length is 18 inches

Step-by-step explanation:

Let's marked first piece with x and second with y

x + y = 42

Given ratio is x : y = 3 : 4

From this proportion we get

x = 3 c and y = 4 c where c is coefficient of proportionality

when we replace this in initial equation we get

3 c + 4 c = 42 => 7 c = 42 => c = 42/7 = 6 c = 6

x = 3 · 6 = 18 inches and z = 4 · 6 = 24 inches

shorter piece is x = 18 inches

God with you!!!

Factor and add steps please<br><br> 81u^6+192

attashe74 [19]

ANSWER : (9u - 8)2

STEPS:

Step-1 : Multiply the coefficient of the first term by the constant 81 • 64 = 5184

Step-2 : Find two factors of 5184 whose sum equals the coefficient of the middle term, which is -144 .

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -72 and -72
81u2 - 72u - 72u - 64

Step-4 : Add up the first 2 terms, pulling out like factors :
9u • (9u-8)

Step-5 : Add up the four terms of step 4 :
(9u-8) • (9u-8)
Which is the desired factorization

Give the values of a, b, and c needed to write the equation's standard form.(5 + x)(5 - x) = 7A = 1; B = 0; C = -18A = 25; B = 0

Maksim231197 [3]

We need to FOIL that out and then get it into standard form to see what our A, B, and C are. FOILing gives us $25-x^2=7$ . If we move the 7 over by subtraction and set it equal to 0, we have $-x^2+18=y$ . In order to avoid a negative leading coefficient, we can change all the signs to get $x^2-0x-18=0$ so A = 1, B = 0, C = -18, first choice above.
