Answer:
Step-by-step explanation:
All the sides are complete, hence we can use the information given to find just 1 triangle
Triangles
From the given information, we have that:
m<B = pi/6 = 30 degres
c = 10
b = 5
This shows that we can use the cosine rule to find the third side b of the triangle. Since all the sides are complete, hence we can use the information given to find just 1 triangle
Answer: -4
Step-by-step explanation:
No options were provided, but i'll simplify this expression.
*the number being NEXT to the parenthesis indicates that you have to multiply.
This expression involves the distributive property. This is when you have a number followed by an equation in parenthesis, like 2(3+1). To solve it, you multiply the number outside of the parenthesis by <u>each number</u> inside them.
-2(5-3)
-2(5) - -2(3)
-10 + 6
-4
So -2(5-3) simplifies to -4. I hope this could help!!
Area should equal 40 yards
Answer:
Erica has 6 more text then Tim and 2 more calls then Tim.
Step-by-step explanation:
What i did was 18-12 because those are both text and that was 6 so Erica has 6 more
Then i did 6-4 =2 and those where both of the calls so Erica has 2 more calls then Tim.
-6x + y = - 4 / + 6x ;
y = 6x - 4 ;
We substitute y in first equation : -5x + 3( 6x - 4 ) = 12;
-5x + 18x - 12 = 12 ;
13x - 12 = 12 ;
13x = 24 ;
x = 24 / 13 ;
y = 6*(24 / 13 ) - 4 ;
y = 144 / 13 - 4 ;
y = 144 / 13 - 52 / 13;
y = 92 / 13 ;
The solution is x = 24 / 13 and y = 92 / 13 ;
