Answer:

(-8)

Step-by-step explanation:

Question :

5x - x + 8

First you can solve the equation simply like this.

5x - x + 8

4x + 8

Now they've given that,

x = (-4)

Now, you have to put -4 instead of x and solve the equation.

Let us solve now.

4 x + 8

4 × (-4) + 8

-16 + 8

(-8)

Hope this helps you :-)

Let me know if you have any other questions :-)

An angle measures 88° more than the measure of a complementary angle. what is the measure of each angle?

aleksandrvk [35]

Let one angle be x
Let second angle be 88+x
Sum of two complementary angles = 90°
x+ 88+ x = 90°
2x + 88 = 90
2x = 90 - 88 = 2
x = 2/2 = 1

First angle = x = 1°
Second angle = 88 + x = 88+1 = 89°
I hope it is helpful:D

Which point would be a solution to the system of linear inequalities ?

brilliants [131]

Answer:

(12,-6)

Step-by-step explanation:

we have

$y\leq \frac{4}{3}x+5$ ----> inequality A

$y\geq -\frac{5}{2}x+5$ ---> inequality B

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities (makes true both inequalities)

<u><em>Verify each point</em></u>

Substitute the value of x and the value of y of each ordered pair in the inequality A and in the inequality B

case 1) (0,-1)

Inequality A

$-1\leq \frac{4}{3}(0)+5$

$-1\leq5$ ----> is true

Inequality B

$-1\geq -\frac{5}{2}(0)+5$

$-1\geq 5$ ----> is not true

therefore

The ordered pair is not a solution of the system

case 2) (0,3)

Inequality A

$3\leq \frac{4}{3}(0)+5$

$3\leq5$ ----> is true

Inequality B

$3\geq -\frac{5}{2}(0)+5$

$3\geq 5$ ----> is not true

therefore

The ordered pair is not a solution of the system

case 3) (-6,-6)

Inequality A

$-6\leq \frac{4}{3}(-6)+5$

$-6\leq-3$ ----> is true

Inequality B

$-6\geq -\frac{5}{2}(-6)+5$

$-6\geq 20$ ----> is not true

therefore

The ordered pair is not a solution of the system

case 4) (12,-6)

Inequality A

$-6\leq \frac{4}{3}(12)+5$

$-6\leq21$ ----> is true

Inequality B

$-6\geq -\frac{5}{2}(12)+5$

$-6\geq -25$ ----> is true

therefore

The ordered pair is a solution of the system (makes true both inequalities)

Together, teamates Pedro and Ricky got 2685 base hits last season. Pedro had 281 more hits than Ricky. How many hits did each pl

Alenkasestr [34]

All we need to do it subtract 281 from 2685 and divide that number by 2 to find out how many base hits Ricky made.
2685 - 281 = 2404
2404/2 = 1202
So Ricky made 1202 base hits
To find out how many Pedro made, just add 281 to Ricky's number and you have your answer
1202 + 281 = 1483
Hope that helps! :)
