Answer:

a = 15

b = -10

Step-by-step explanation:

Here, we want to solve the system of linear equations

Firstly, let us multiply the first equation through by 10

2a - 5b = 100 ••••(i)

from the second equation;

a = 29 + b

Substitute this into i

2(29 + b) - 5b = 100

58 + 2b -5b = 100

-3b = 100-58

3b = 42

-b = 42/3

-b = 14

recall;

a - b = 29

a - (-14) = 29

a + 14 = 29

a = 29-14 = 15

Answer:

a = 15

b = - 14

Step-by-step explanation:

Solve the equation for a

a = 29 + b

Substitute the given value of a into the equation  [tex]\frac{a}{5}-\frac{b}{2}=10[/tex]

[tex]\frac{29+b}{5}- \frac{b}{2} =10[/tex]

Solve the equation for b

b = - 14

Substitute the given value of b into the equation a = 29 + b

a = 29 + (- 14)

Solve the equation for a

a = 15

The possible solution of the system is the ordered pair (a, b)

(a, b) = (15, -14)

Check if the given ordered pair is the solution of the system of equations

[tex]\frac{15}{5} - \frac{-14}{2} = 10[/tex]

[tex]15-(-14) = 29[/tex]

Simplify the equalities

10 = 10

29 = 29

Since all of the equalities are true, the ordered pair is the solution of the system

(a, b) = (15, -14)

This is a translation.

A translation moves things up and down.

The figure stays in the same direction so reflection and rotation, glide reflection are wrong.

Answer:

So, /(100÷2) = 117/50 when reduced to the simplest form. As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 234/100 is also equal to 2 17/50 when expressed as a mixed number.

Step-by-step explanation:

Answer:

2 17/50

Step-by-step explanation:

234%

= 234/100

= 2 34/100

= 2 17/50

Answer:

[tex]Total\ water\ drank = 1\frac{7}{20}\ liters[/tex]

Step-by-step explanation:

Amount of water drank before jogging = 3/4 liter

Amount of water drunk after jogging = 3/5

Total amount of water drunk = amount drank before jogging + amount drank after jogging

[tex]Total\ water\ drunk\ = \frac{3}{4} + \frac{3}{5} = \frac{15+ 12}{20} = \frac{27}{20}\\converting\ to\ a\ mixed\ number\\ \frac{27}{20}= 1\frac{7}{20}\\\therefore Total\ water\ drank = 1\frac{7}{20}\ liters[/tex]

Answer:

Step-by-step explanation:

Expand -(1/5)-x+2+3

-(1/5)-x+2+3

Remove the parenthesis;

=1/5-x+2+3

Add the numbers; 2+3=5

=-x+5-1/5

Convert element to fraction;

=5*5-1/5

Since the denominators are equal combine the fractions;

5*5/5-1/5

5*5-1=24

Multiply the numbers;5*5=25

=25-1

Subtract the numbers:25-1=24

=24

=-x+24/5

-12x+26=-x+24/5

Subtract 26 from both sides;

-12x+26-26=-x+24/5-26

Simplify;

-12x+26-26

Add similar elements; 26-26=0

=-12x

Simplify;-x+24/5-26

Convert element to fraction;

- 26/*5/5+24/5

Since the denominators are equal , combine the fractions;

-26*5+24

Multiply the numbers; 25*5=130

=-130+24

Add/subtract the number;-130+24=-106

=-106

=-106/5

Apply the fraction rule;

=-x-106/5

-12x=-x-106/5

Add x to both sides;

-12x+x=-x-106/5+x

Simplify;

-11x+=-106/5

Divide both sides by -11

-11x/-11=-106/5/-11

Simplify ;-11x/-11

Divide ;11/11

=1

=x

simplify;-106/5/-11

Apply fraction rule; 106/5/11

106/5*11

Multiply the numbers;5*11=55

=106/55

x=106/55

Answer:

85

Step-by-step explanation:

as the lines are parallel, the 95 angle is the same as the angle below x.

So to find x you take 95 from 180 because angles on a straight line add up to 180.

therefore x = 85

Answer:

16 had the cheaper ticket

Step-by-step explanation:

Let the number of 75cents tickets be x

Let the number of $1.25 tickets be y

Since the total tickets is 40, hence;

x+y =40 .... 1

Also if some are sold at 75 cents and the rest at $1.25 with total of $42 earned, then;

0.75x+1.25y = 42... 2

From 1

x = 40-y

Substitute into 2;

0.75(40-y)+1.25y = 42

30-0.75y+1.25y = 42

30+0.5y = 42

0.5y =42-30

0.5y = 12

y = 12/0.5

y = 24

Since x = 40-y

x = 40-24

x = 16

The number of cheaper ticket are 16
