Let's say Ronnie is thinking of X.
If 2(x) = x+5, we would first distribute the 2.
2x = x+5
We would then need to isolate the variable. We would do so by getting all variables to one side. The easier choice would be to subtract x from both sides.
2x=x+5
-1x -1x
This becomes
x=5
Ronnie is thinking of the number five.
5•2=10 and 5+5=10.
Answer: ABC EASY AS 123
Step-by-step explanation:
Answer:
9 inches
Step-by-step explanation:
Here, we want to know the greatest length of the third side
We apply the triangle inequality theorem here
To get the third side, then the sum of the lengths of the two must be greater than the measure of the third side
let us call the third side x
Then;
5 + 5 > x
10 > x
The highest whole number before 10 is 9: so it is the greatest possible whole number the base of the isosceles triangle can have
Answer:
3/10
Step-by-step explanation:
fouth grade students at Estrabook make up 0.3 percents of the students at school
The fraction is therefore equivalent to
= 3/10
Answer:
-2/7
Step-by-step explanation:
solve for x so -12+ 8 = 30x - 16x so -4 = 14x so x = -4/14, so x = -2/7
