25/16=1.5625
5/4=1.25
They are not proportionally equivalent.

No, because you can't simplify 25:16.
Another way to figure out why it is not proportional is to divide.
16 / 25 = 0.64
4/5 = 0.6
0.64 and 0.6 are not equal.

Hope this helps!

Answer: (1,-1)

Step-by-step explanation:

- You can multiply the first equation by -1

- Add the equations.

- Solve for x, as following:

$\left \{ {{-5x - 4y = -1} \atop {-3x + 4y = -7}} \right.\\------\\-8x=-8\\x=1$

- Substitute the value of x into any of the original equations and then you must solve for y:

$5(1)+4(y)=1\\4y=-4\\y=-1$

Therefore, the solution is: (1,-1)

Simplify each expression.

Elina [12.6K]

Step-by-step explanation:

remember that x^-n means 1/(x^n).

x^a × x^b = x^(a+b)

x^a / x^b = x^(a-b)

(x^a)^b = x^(a×b)

(x×y)^n = x^n × y^n

so,

a^2 / a^-2 = a^(2 - -2) = a^4

and

b^-3 / b^2 = b^(-3 - 2) = b^-5 = 1/(b^5)

that means we have then :

(a^4 × b^-5)^2 = (a^4)^2 × (b^-5)^2 = a^8 × b^-10 =

= a^8 / b^10 = a⁸/b¹⁰

Answer:

The real-life distance to the nearest mile between Tampa and Orlando is 88 miles

Step-by-step explanation:

String distance between Fort Myers and Miami = 7 inches

A real life distance between Fort Myers and Miami = 154 miles

So, 7 inches = 154 miles

$1 inch = \frac{154}{7}=22 miles$

Scale : 1 inch = 22 miles

String distance between Tampa and Orlando = 4 inches

Using scale

The real-life distance to the nearest mile between Tampa and Orlando = $4 \times 22 = 88 miles$

Hence The real-life distance to the nearest mile between Tampa and Orlando is 88 miles
