Step-by-step explanation:
4x - 9 = 23
4x = 32
x = 8
the number is 8.
Remember that sides AC and EG will correspond. By finding the ratio of the lengths of these sides, we can find the length of EF.
The ratio of 4 to 16 simplifies to 1:4. This means that every side in ABDC is 1/4th of its corresponding side in EFHG. 16 times 4 is 64, so EF has a length of 64 units.
Basically you have to solve for the value of Y when x= 4
So you have -5y= 11 - 2x
y = -11/5 + 2/5x
therefore when x = 4 , y = -3/5
Answer: 2 sticks.
Step-by-step explanation:
Given statement: You need 3 sticks of butter for every 24 cookies you bake.
Using unitary method , the number of sticks of butter used to bake 1 cookie=
Then the number of sticks of butter used to bake 1 cookie=
Hence, the number of sticks of butter used to bake 16 cookies= 2
