Step-by-step explanation:
5x-15=2x+21(AIA)
3x-15=21
3x=36
x=12
2.5875
Step-by-step explanation:
look first the mixture is 4 Apple: 5 cranberry okay and the will make 1:5 littre so you will mince 4:5 from 1:5 and you will get 3:5. 3 for appple.and 5 for the other so you will make the next equations 3×0.45= . and 5×0.8= . and you will get the apple price and the second price so you will make new apple price: new cranberry price=
Answer: XY = 8
Step-by-step explanation:
The diagram of the triangle XYZ is shown in the attached photo.
XY=XZ. This means that two sides of the triangle are equal. Two angles are also equal. It means that the triangle XYZ is an isosceles triangle.
Since XY=XZ, then
2a = 5a - 12
Subtracting 2a from both sides of the equation,
2a - 5a = 5a - 12 - 5a
-3a = -12
a = -12/-3
a = 4
Therefore, the length of XY is 2a = 2×4 = 8
Answer:
Isolate.
Step-by-step explanation:
To solve a one-step equation, you must isolate the variable.
For example,
3x = 9.
You must isolate x, which just means you have to get x by itself.
Divide by 3 on both sides to get x by itself.
x = 3.
The answer to this question is isolate.
