Answer:

Mark answer C and D as correct

Step-by-step explanation:

Recall that a bisector cuts the side in two equal segments, then KH has to be half of 136 that is KH = 68

Also KHZ and HLZ are right angle triangles that share the same hypotenuse, so they are congruent triangles, which means that HL must equal KH and therefore the full side HJ must be 68 times 2 = 136

Solve the system of equations and choose the correct order pair.

Aneli [31]

$(2x + 4y = 14) \div 2 = x + 2y = 7$
making x the subject
$x = 7 - 2y$
substitute into second equation
$3(7 - 2y) + 12y = 51$
by solving, y=5

substitute into first equation
$2x + 4(5) = 14$
by solving, x=-3

Therefore the ordered pair is (-3,5)

1/3 cup of flour is used to make 5 dinner rolls. how many cups of flour are needed to make 3 dozen dinner rolls

MAVERICK [17]

F = Cup of flour

D = Dinner roll(s)

12 = A dozen

36 = Three dozen

---------

1/3 * F = 5 * D

n * F = 36 * D

------

$\frac { 1 }{ 3 } F=5D\\ \\ 3\cdot \frac { 1 }{ 3 } F=3\cdot 5D\\ \\ F=15D$

$nF=36D\\ \\ n=\frac { 36D }{ F }$

This means that...

$n=\frac { 36D }{ 15D } \\ \\ n=\frac { 36 }{ 15 } \\ \\ n=\frac { 3\cdot 12 }{ 3\cdot 5 } \\ \\ n=\frac { 12 }{ 5 } \\ \\ n=\frac { 10 }{ 5 } +\frac { 2 }{ 5 } \\ \\ n=2+\frac { 2 }{ 5 }$

And this means that two cups of flour and 2/5 of a cup of flour are required to make 3 dozen dinner rolls.
