Answer:

20 degrees.

Step-by-step explanation:

The 3 angles of a triangle add up to 180 degrees.

Therefore the third angle in this triangle

= 180 - (120 + 40)

= 180 - 160

= 20 degrees.

How do I solve: 6x^2 -x-12=0 ^2 means squared by the way!

Alchen [17]

$6x^2 -x-12=0\\
6x^2+8x-9x-12=0\\
2x(3x+4)-3(3x+4)=0\\
(2x-3)(3x+4)=0\\
x=\frac{3}{2} \vee x=-\frac{4}{3}

Annie wants to make several plates of apples apricots, so that each plate has the same number of apples and the same number of a

Vilka [71]

Answer:

Annie can make 4 plates with $8:4=2$ apples and $20:4=5$ apricots on each plate.

Step-by-step explanation:

Annie has 8 apples and 20 apricots.

Factor these numbers:

$8=2\cdot 4=2\cdot 2\cdot 2\\ \\20=2\cdot 10=2\cdot 2\cdot 5$

Find GCF(8,20):

$GCF(8,20)=2\cdot 2=4$

Hence, Annie can make 4 plates with $8:4=2$ apples and $20:4=5$ apricots on each plate.

Which equation represents a proportional relationship that has a constant of proportionality equal to –10?

aksik [14]

Answer:

y = - 10x

Step-by-step explanation:

The equation representing a proportional relationship is

y = kx ← k is the constant of proportionality

y = - 10x ← is the only equation in this form

Thus the equation is y = - 10x with k = - 10
