Answer:
u transpose all the constans to one side of the '=' sign and solve
Step-by-step explanation:
for example,
in the first question
the sides of the triangles are proportional then,
25/30 = x/ 10
=> (25x10)/30 = x
=> 250/30 = x
=> 8.33
im pretty sure like this u can do the rest, ;)
The formula is y2-y1 divided by x2-x1 So now-5+7divided by -2+1 =2/-1= -2
The answer would be 20% divide 9 by 45 and you get the answer of 0.2. When we use percents, we multiply the value by 100 so 0.2 x 100 you move the decimal over 2 places to the right. This means it would be 20% of the whole.
