Get 9 to the other side by subtracting 9 on both sides which leaves you with x= -2 because 7-9= -2
Answer:
In total, it sells 90 loaves.
Step-by-step explanation:
The number of loaves of bread sold is:
20 on Wednesday
25 on Thursday
On Friday, it does the same as Wednesday and Thursday combined. So 20 + 25 = 45.
How many total loaves does it sell?
20 + 25 + 45 = 90
In total, it sells 90 loaves.
Answer:
400
Step-by-step explanation:
So you need to isolate the variable in order to get your answer. This is how you do it.
3x + 5 = 2x - 7
Subtract 2x from both sides.
1x + 5 = -7
Subtract 5 from both sides to have the variable by itself.
1x = -12
Divide 1 to both sides to find the value of x.
x = -12
Now we need to check.
3(-12) + 5 = 2(-12) - 7
-36 + 5 = -24 - 7
-31 = -31
Since both sides or the same you now know that -12 is the solution.

Answer:
3/13
Step-by-step explanation:
There are 28 students. 1 studies biology but not art. 1 studies neither subject. Therefore, there are 26 students who study art.
Of the 26 students who study art, 6 also study biology. So the probability is 6/26, which reduces to 3/13.
