A certain drug is made from only two ingredients: compound A and compound B. There are 3 milliliters of compound A used for ever

Sphinxa [80]

Answer:

$304\dfrac{4}{7}\ milliliters$

Step-by-step explanation:

If there are 3 milliliters of compound A used for every 4 milliliters of compound B, then we can denote that we use 3x milliliters of compound A and 4x milliliters of compound B to get 533 milliliters of the drug. Thus,

$3x+4x=533,\\ \\7x=533,\\ \\x=\dfrac{533}{7}\ milliliters.$

Hence, a chemist must take

$4\cdot \dfrac{533}{7}=\dfrac{2132}{7}=304\dfrac{4}{7}\ milliliters$

of compound B.

Can you guys help me!!!!<br><br> Please make sure to include steps!!!!!

1) 13.02-6y=8y
+6y=6y
13.02=14y then divide both sides by 14. you get y= .93
2) 1/5x+5=19-1/2x
-5=-5
(1/5x=14-1/2x)5
x=70-2.5x
+2.5x=+2.5x
3.5x=70 divide both sides by 3.5 and you get x=20
3) 7.3t+22=2.1t-22.2
-2.1t =-2.1t
  5.2t+22=22.2
  -22=-22
5.2t=-44.2 divide both by 5.2 and t=-8.5
4) (1.4+2/5e=3/15e-.8)15
21+6e=3e-12
  -3e=-3e
21+3e=-12
-21 =-21
3e=-33 divide both by 3 and e=-11
5) 5(x-4)=2(2x+5)
5x-20=4x+10
-4x -4x
x-20=10
+20=+20
  x=30
6) -7(3+t)=4(2t+6)
   -21-7t=8t+24
+7t=+7t
-21=15t+24
-24= -24
-45=15t divide both by 15 and t=-3
7) (3/4x+6=1/3x+9)4
3x+24=1.3x+36
-1.3x =-1.3x
1.7x+24=36
-24=-24
1.7x =12 divide both sides by 1.7 and x=7.06

Explain the relationship between the polynomial identities: x^2 − 1 = (x +1)(x − 1) and x^2 − a^2 =(x − a)(x +a).

Bess [88]

Answer:

So these two equation can be related by identity $x^2-a^2=(x+a)(x-a)$

Step-by-step explanation:

We have given equation $x^2-1=(x+1)(x-1)$

And $x^2-a^2=(x+a)(x-a)$

We know the algebraic identity $a^2-b^2=(a+b)(a-b)$

From this identity

$x^2-1$ can be written as (x+1) (x-1)

And using same identity $x^2-a^2$ can be written as $(x-a)(x-b)$

So these two equation can be related by identity $x^2-a^2=(x+a)(x-a)$

Bethany runs 5.4 miles around her neighborhood. She runs at a constant pace

il63 [147K]

Answer:

0.09

Step-by-step explanation:

Given the following question:

$5.4\div60$

In order to find the answer, we will find the total miles ran, by the total amount of time Bethany spent running.

$5.4\div60=0.09$
$=0.09$

Which means Bethany runs "0.09 of a mile each minute."

Check your work:
$0.09\times60=5.4$
$=5.4$

Hope this helps.
