Solving rational equations<br><br> solve for x: 3/x-4=7/x
KIM [24]

Solving the rational equation \frac{3}{x-4}=\frac{7}{x} the value of x is 7

Step-by-step explanation:

We need to solve rational equation: \frac{3}{x-4}=\frac{7}{x} and find value of x.

Solving:

\frac{3}{x-4}=\frac{7}{x}

Cross multiplying:

3(x)=7(x-4)\\Simplifying:\\3x=7x-28\\3x-7x=-28\\-4x=-28\\x=-28/-4\\x=7

So, value of x = 7.

Solving the rational equation \frac{3}{x-4}=\frac{7}{x} the value of x is 7

The width of a rectangle is 1.9 feet. The perimeter is 7.4 feet. What is the length?
dimaraw [331]

Answer:2.8 feet

Step-by-step explanation:

length(l)=?

breadth(b)= 1.9 feet

perimeter(p)=7.4 feet

we know,

p=2(l+b)

7.4=2(l+1.9)

7.4=2l+3.8

2l=7.4-3.8 (changing side and bringing 3.8 to 7.4 it gets -3.8)

l=3.6/2

l=2.8 feet

Hence,length is 2.8 feet

Someone help pleaseeee
qaws [65]

Answer:

Part A = D

Part B = 5 and 50

Step-by-step explanation:

Part A:

area = 5*4x = 20x

so, 100 \leq 20x \leq  1000

Part B:

to leave it only by x, you divide both sides by 20

100/20 = 5, 1000/20 = 50

which 5\leq x\leq 50
