6 + x (x is the number of pens needed to EQUAL to 10)

6 + x = 10

x = 4

Sanity check:

Equality Properties

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of Equality

Algebra I

Terms/CoefficientsSolving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

5x + y = 9

10x - 7y = -8

Step 2: Rewrite Systems

Manipulating: Equation 5x + y = 9

Subtract 5x on both sides:                    y = 9 - 5x

Step 3: Redefine Systems

y = 9 - 5x

10x - 7y = -8

Step 4: Solve for x

Substitution

Substitute in x:                    10x - 7(9 - 5x) = -8Distribute -7:                        10x - 63 + 35x = -8Combine like terms:           45x - 63 = -8Add 63 on both sides:        45x = 55Divide 45 on both sides:    x = 11/9

Step 5: Solve for y

Define equation:                    5x + y = 9Substitute in x:                       5(11/9) + y = 9Multiply:                                  55/9 + y = 9Isolate y:                                 y = 26/9

if if 30 per increase in the salary of usman results in rs.4500 what was the actual salary of usman​

Answers

Answer:

The actual salary of usman was Rs. 3461.53

Step-by-step explanation:

Given that:

Percent increase in salary = 30%

Total salary percent would be = (100+30)% = 130%

Salary after increment = Rs. 4500

Let,

x be the actual salary before increase.

According to given statement,

130% of x = 4500

[tex]\frac{130}{100}x=4500\\1.3x=4500[/tex]

Dividing both sides by 1.3

[tex]\frac{1.3x}{1.3}=\frac{4500}{1.3}\\x=Rs 3461.53[/tex]

Hence,

The actual salary of usman was Rs. 3461.53

what is the value of x in the equation -2/3 x + 9 = 4/3 x - 3​

Answers

Answer:

x=6

Step-by-step explanation:

This equation requires simplifying. We start with moving like terms to each other:

3 + 9 = 4/3x + 2/3x

After this, add the like terms together:

12 = 6/3x

6/3 will simplify into 2:

12=2x

Finally, divide both sides by 2:

Richie and bethany play basketball and practice shooting free throws after school. During one practice session, Richie attempted 15 free throws and made 12 of them.

a. bethany made eight free throws for every 3 that she missed. Did bethany do better than richie? how do you know.

Answers

Answer:

Bethany did not do better than Richie because her average score was less than his.

Step-by-step explanation:

Average Value

The average or mean value of m successes out of n tries is given by:

[tex]\displaystyle \bar x=\frac{m}{n}[/tex]

During a practice session playing basketball, Richie made m=12 free throws from n=15 attempts. His average score was:

[tex]\displaystyle \bar x=\frac{12}{15}=0.8[/tex]

Bethany made 8 free throws for every 3 that she missed, this means she made 8 out of 11 attempts. Her average score was:

[tex]\displaystyle \bar x=\frac{8}{11}=0.72[/tex]

Bethany did not do better than Richie because her average score was less than his.

The person that did better is Richie. This is because the percentage of free throws made by Richie is higher than that of Bethany.

In order to determine who did better, the percentage of free throws made has to be determined.

The percentage of free throws made by Richie =( 12 / 15) x 100 = 80%

The  percentage of free throws made by Bethany = [(8-3) / 8] x 100 = 62.50%

The well-known state of East Dakota spent approximately $80.8 billion in 2016. Its population at that time was about 3.203 million people. How much did East Dakota spend per capita in 2016? Round to the nearest dollar.

Answers

Answer:

$25,226

Step-by-step explanation:

We know that one billion is equal to 1,000 millions

So, we first multiply 80.8 by 1,000 so we can use millions as our unit.

Which gives you $80,800

So, East Dakota spent $80,800 million in 2016 for the 3.203 million people. Right now, we just ignore the "million" part and divide 80,800 by 3.203 which is around 25,226.35029659694

Now we just round it to the nearest dollar and since the tens place is only at 3, we round down.

Hence, our answer is $25,226

Experimental Value - Actual Valuel
Percent Error =
Actual Value
x 100
The percent error of Bob's measurement is
%.

Answers

Answer:

% error = 3.3%

Step-by-step explanation:

Percent Error Formula:

% error = ( (MeasuredValue - AcceptedValue) / AcceptedValue ) * 100

% error = ( (12.7 - 12.3) / 12.3 ) * 100

% error =  (0.4/12.3) * 100

% error = (0.03252033) * 100

% error = 3.25203252

% error = 3.3%

4. x = 17

2. x = 77; y = 103

Step-by-step explanation:

4. The acute angles of a right triangle are complementary.

2x + 3x + 5 = 90

5x = 85

x = 17

2.

Same side interior angles are supplementary.

x + 103 = 180

x = 77

y and 103-deg angle are vertical angles, so they are congruent.

· Lucy buys 3 apples and 6 mangos for a total of $9.15.


· Amir buys 8 apples and 4 mangos for 11.92.


What is the cost of a single apple?

Answers

Answer:

0.97

Step-by-step explanation:

Let x be the cost of apples

Let y be the cost of mangoes

3x + 6y= 9.15......equation 1

8x + 4y= 11.92........equation 2

Multiply equation 1 by 8 and equation 2 by 3

24x + 48y = 73.2

-

24x + 12y = 35.76

36y = 37.44

y = 37.44/36

y= 1.04

Substitute 1.04 for y in equation 1

3x + 6y = 9.15

3x +6(1.04)= 9.15

3x + 6.24= 9.15

3x = 9.15-6.24

3x = 2.91

x = 2.91/3

x = 0.97

Hence the price of a single apple is 0.97
