What is the sum of two numbers is 45 and theire difference is 5

adelina 88 [10]

Answer:

let the two numbers be x and y

x+y=45(equation 1)

x-y=5(equation 2)

from equation (1) y=45-x(equation 3)

substitute 45-x for y in equation 2

x-(45-x)=5

x-45+x=5

x+x-45=5

2x-45=5

2x=45+5

2x=50

x=50/2

x=25

Answer:

p = 4$

Step-by-step explanation:

p + 25%p = $5

p + 25p/100 = 5

⁴⁾p + p/4 = ⁴⁾5

4p + p = 20

5p = 20

p = 20 : 5

p = 4$

Evaluate M^2 /p^2 for M = 10, N =-5p and P = -2

kondaur [170]

Answer:

The solution of $\bold{\frac{M^{2}}{P^{2}}}$ for M = 10, N = -5P and P = -2 is 25

Solution:

From question, given that the value of M is 10 and N is -5p and P is -2

We have to evaluate the value of $\frac{M^{2}}{P^{2}}$ ,

By substituting the values of M and N, we get

$\frac{M^{2}}{P^{2}} = \frac{10^{2}}{(-2)^{2}}$

Expanding $\bold{10^{2}}$ :

Here 10 is the base value and 2 is the exponent value. So the base term 10 is multiplied by itself two times.

$10^{2} = 10 \times 10 = 100$

Similarly expanding $\bold{(-2)^{2}}$ :

Here -2 is the base term and 2 is the exponent value. So the base term -2 is multiplied by itself two times.

$(-2)^{2} = -2 \times -2 = 4$

So the equation $\frac{M^{2}}{P^{2}} = \frac{10^{2}}{(-2)^{2}}$ becomes,

$\frac{M^{2}}{P^{2}} = \frac{100}{4}$

By dividing 100 by 4 , we get the result as 25

Hence the solution of $\bold{\frac{M^{2}}{P^{2}}}$ when M = 10 and P = -2 is 25

Find the percent of increase for 4 to 7. round to the nearest tenth if necessary. also someone please explain how to do this.

dem82 [27]

Answer:

75%

Step-by-step explanation:

The percent increase is calculated as

percent increase = $\frac{increase}{original number}$ × 100%

increase = 7 - 4 = 3, thus

% increase = $\frac{3}{4}$ × 100% = $\frac{3(100)}{4}$ = 75%
