Answer:

A. Adjacent Angles

If you look at the image given, there is a line which have the points, K and J. Angles A and B share that line and share the same vertex point which is J. Just by looking at it, you should be able to understand that they add up to 180 degrees since they are both right angles or 90 degree angles (90+90=180). When two angles have all these, they are Adjacent angles.

Naily [24]

Answer:

n=2

Step-by-step explanation:

7+14 = 7+7*2

7*2=14

1,617 -7 =1,610

1,610: 14 = 115

Al numero 7 se le suma 115 veces el numero 14(que es lo mismo que 7*2)

115*14 = 1,610

7+1,610 = 1,617

How would you substitute 2x+3y=12 and 4x=10+y

Helen [10]

Answer:

Step-by-step explanation:

$\left\{\begin{array}{ccc}2x+3y=12\\4x=10+y&\text{subtract 10 from both sides}\end{array}\right\\\\\left\{\begin{array}{ccc}2x+3y=12&(1)\\4x-10=y&(2)\end{array}\right\\\\\text{Substitute (2) to (1):}\\\\2x+3(4x-10)=12\qquad\text{use the distributive property}\\2x+(3)(4x)+(3)(-10)=12\\2x+12x-30=12\qquad\text{add 30 to both sides}\\14x-30+30=12+30\\14x=42\qquad\text{divide both sides by 14}\\\\\dfrac{14x}{14}=\dfrac{42}{14}\\\\x=3$

$\text{Put it ot (2):}\\\\y=4(3)-10\\y=12-10\\y=2$
