Answer:
x=13°
Step-by-step explanation:
It is given that triangles ABC and EDC are similar, therefore angles ABC and EDC have the same measurement. Using this information, we can set up an equation.
We can remove the parentheses, as they are unnecessary.
We can now solve the equation for x. The first step is subtracting 16 from both sides.
We can now divide both sides by 8, to isolate x. 104/8=13.
Lets not forget to add the degree symbol, as the problems is dealing with degrees.
x=13°
Answer:
Step-by-step explanation:
Yes, she can use this inequality and it does matter since the number of cars that the inequality provides will need to be equal to or more than that number in order for all the students to be able to go. Therefore, if we apply the inequality it would give us the minimum number of cars needed (n) like so
12 + 3n > 28 ... subtract 12 on both sides
3n > 16 ... divide both sides by 3
n > 5 1/3
Since there can't be 1/3 of a car and the number of cars needed must be higher than 5 1/3 then we would need a total of 6 cars to take all of the children.
Answer:
4
Step-by-step explanation:
4 us the rifht answer just put 4
-5(x+3)=-4x-15
-5x-15=-4x-15
-5x+4x=-15+15
-1x=0 /-1
x = 0
