Answer:1.7 its positive
Step-by-step explanation: 0,15 . 16,-12
y1-y2/x1-x2
15-(-12)= 27
0-16= 16
27/16 = 1.7
You will need 6/4 or 1 1/2 cups of blueberries to make 48 muffins (2 dozen),
3(x-7) = 138 + 3x First multiply
3x-21 = 138 + 3x subtract 3x from both sides
-21 = 138
This is a false statement because -21 does not equal to 138 so the answer is no solution.

To find the answer, you need to solve for b.
2(2b + 3) = 12 divide both sides by 3
2b + 3 = 6 divide both sides by 2
2b = 3 subtract 3 from both sides
b = 1.5 divide both sides by 2
b = 1.5 satisfies the equation. if you plug 1.5 in, you get that the equation is true.
Answer:
Sure.
Step-by-step explanation:
So X is a variable meaning its a letter that represents a number. When there are a number and a variable (or a letter) like this 2x or 9y it means you are going to multiply the number by the variable. In this case it is 7 times x is equal to 21 so all we have to do is find what times 7 is equal to 21 and that number is 3. So if 7*x=21 is 7*3=21 then x=3. If you have any questions ill be more than open to answering them, hopefully this helped. Have a good day/night.
