3)180-105=75
4) -8+83=75
Answer:
8.54
Step-by-step explanation:
distance formula is d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}
plug in the coordinates the answer is 8.54
Answer:
2 × 5 = 10
Step-by-step explanation:
Answer:
x=3+3/4
Step-by-step explanation:
1+4x/6=3.5
We move all terms to the left:
1+4x/6-(3.5)=0
We add all the numbers together, and all the variables
4x/6-2.5=0
We multiply all the terms by the denominator
4x-(2.5)*6=0
We add all the numbers together, and all the variables
4x-15=0
We move all terms containing x to the left, all other terms to the right
4x=15
x=15/4
x=3+3/4
