Mathematics

Aneli [31]2 years ago
5 0

Answer: x=15

Step-by-step explanation: Let's solve your equation step-by-step.

x+ 1 /2

(x−5)=20

Step 1: Simplify both sides of the equation.

x+ 1 /2

(x−5)=20

x+( 1 /2 )(x)+( 1 /2 )(−5)=20(Distribute)

x+ 1 /2

x+  −5 /2 =20

(x+ 1 /2 x)+( −5 /2 )=20(Combine Like Terms)

3 /2 x +  −5 /2 =20

3 /2 x +  −5 /2 =20

Step 2: Add 5/2 to both sides.

3 /2 x +  −5 /2  +  5 /2 =20+ 5 /2

3 /2 x=  45 /2

Step 3: Multiply both sides by 2/3.

( 2 /3 )*( 3 /2 x)=( 2 /3 )*( 45 /2 )

x=15

Solve the equation to find the value of m and n.<br> 2m + 3n = -5<br> 5m + 3n = 1
Leokris [45]

Answer:

m = 2, n = - 3

Step-by-step explanation:

Given the 2 equations

2m + 3n = - 5 → (1)

5m + 3n = 1 → (2)

Subtract (2) from (1) term by term to eliminate n

2m - 5m = - 5 - 1

- 3m = - 6 ( divide both sides by - 3 )

m = 2

Substitute m = 2 into either of the 2 equations and solve for n

Substituting into (1)

2(2) + 3n = - 5

4 + 3n = - 5 ( subtract 4 from both sides )

3n = - 9 ( divide both sides by 3 )

n = - 3

The table compares x, the number of minutes of television Sam watched each day, to y, the number of minutes she spent exercising
Ahat [919]

For this case we have the following variables:

x: the number of minutes of television Sam watched each day

y: the number of minutes she spent exercising

Then, we have the following function that models the problem:

y = -0.78x + 95

if she spends 30 minutes watching television we have x = 30.

Substituting in the given equation we have:

y = -0.78 (30) + 95\\y = 71.6

Answer:

the best prediction for the number of minutes of exercising Sam will do if she spends 30 minutes watching television that day is:

72 minutes
