If the equation were 6x + 2 = 5x + 17, would there be one unique solution?

1 answer:

8 0

Yes, because if you were to figure out what x= you would get 15. Try any other numbers, and they do not work

6x+2=5x+17
6x=5x+15
X=15

svp [43]

Answer:

$Xs=30cm$ and $As=900 cm^{2}$

Step-by-step explanation:

At=As+Ar; A=b.h and $At=4500 cm^{2}$ , then: At=(x+120)x so

(x+120)x=4500, $x^{2} +120x-4500=0$ Applying cuadratic equation formula: $\frac{120+-\sqrt{120^{2} -4.1.-4500} }{2} =-\frac{120+-\sqrt{14400+18000} }{2}= x1=30 and x2=-150, finally Xs=30cm, and As=900cm^{2}$

There are 11 more goats than sheep in the farm. Together there are 137 animals in the farm. How many goats and how many sheep ar

VashaNatasha [74]

Answer:

The number of goats in the farm is $74$

The number of sheep in the farm is $63$

Step-by-step explanation:

Let

x----> the number of goats in the farm

y----> the number of sheep

we know that

$x+y=137$ ----> equation A

$x=y+11$ -----> equation B

substitute the equation B in equation A and solve for y

$(y+11)+y=137$

$2y=137-11$

$2y=126$

$y=126/2=63$

Find the value of x

$x=63+11=74$

therefore

The number of goats in the farm is $74$

The number of sheep in the farm is $63$

Dafna1 [17]

Answer:

1075/42

Step-by-step explanation:

$\dfrac{250}{12}+\dfrac{100}{21}=\dfrac{250(21)+(12)100}{(12)(21)}=\dfrac{6450}{252}\\\\=\dfrac{(6)(1075)}{(6)(42)}=\boxed{\dfrac{1075}{42}}$
