5, 11 and 2 are all prime numbers which add together to create 18.
5+11=16+2=18

For these types of questions you have to think it out. List the prime source lower than 18. 2,3,5,7,11,13,17. Then take a look and test some pairs.

Eventually you'll find that 11, 5, 2 is a solution.

Answer: b) two sides and the included angle are congruent

<u>Step-by-step explanation:</u>

RS = QS SIDES are congruent

∠PSR ≡ ∠PSQ ANGLES are congruent

PS = PS SIDES are congruent

ΔPSR ≡ ΔPSQ by the Side-Angle-Side (SAS) Congruency Theorem

Since we know the triangles are congruent, we can state that their parts are congruent:

Find the solution of the system of equations.<br> −5x+5y=-10<br> 6x+5y=1

pickupchik [31]

Answer:

Step-by-step explanation:

Since you have

in one equation and

−

in the other equation, you can add both equations to cancel out the y terms and solve for x.

−

therefore

−

multiplying both sides by -1:

−

plugging this back into the first equation:

−

(

−

)

subtracting 66 from both sides:

−

divide both sides by 5:

−

putting the x-values and y-values into one point gives:

(

−

)

as the solution

One adult ticket costs £11 and one child ticket costs £8.5

Step-by-step explanation:

Let,

Adult ticket = a

Child ticket = c

According to given statement;

3a+4c=67 Eqn 1

5a+6c=106 Eqn 2

Multiplying Eqn 1 by 5;

$5(3a+4c=67)\\15a+20c=335\ \ \ Eqn\ 3$

Multiplying Eqn 2 by 3;

$3(5a+6c=106)\\15a+18c=318\ \ \ Eqn\ 4$

Subtracting Eqn 4 from Eqn 3

$(15a+20c)-(15a+18c)=335-318\\15a+20c-15a-18c=17\\2c=17\\$

Dividing both sides by 2

$\frac{2c}{2}=\frac{17}{2}\\c=8.5$

Putting c=8.5 in Eqn 1

$3a+4(8.5)=67\\3a+34=67\\3a=67-34\\3a=33$

Dividing both sides by 3;

$\frac{3a}{3}=\frac{33}{3}\\a=11$

One adult ticket costs £11 and one child ticket costs £8.5
