The estimate of the sum of 202 and 57 is 260. You add the numbers together and than round up.
6; because they are an equal distance apart
You need to get rid of -6 by adding 6, you also need to add 6 to 18.
4x = 24
Now you need to get rid of the 4 attached to the variable, you do this by dividing 4 since it is multiplying, also dividing 4 and 24
x = 6
So the value of x is 6
Hope this helps! :)
Triangle ABC and triangle DCE are congruent, so line DE = line AB
Use the cosine rule to find angle ACB
Angle ACB = 48.1°
The slope of the line passing through (1,-5) and (4,1) is 2
