Answer:
y=3
Step-by-step explanation:
y = 3x2 + 3x-1
y = 6 + -3
y = 3
Answer:
x= 0
Step-by-step explanation:
6x-4=2(3x-2)
or,6x-4=6x-4
or,x=o
Add all the sides together
7.2+14.8+16.1+18 = 56.1
There 7 blocks of hundreds which means each such block is equivalent to 100.
There are 5 blocks of tens, which means each such block is equivalent to 10.
There are 8 blocks of ones, which means each such block is equivalent to 1.
The total of these blocks will be = 7(100) + 5(10) + 8(10) = 758
We can make several two 3-digit numbers from these blocks. An example is listed below:
Example:
Using 3 hundred block, 2 tens blocks and 4 ones block to make one number and remaining blocks to make the other number. The remaining blocks will be 4 hundred blocks, 3 tens blocks and 4 ones blocks
The two numbers we will make in this case are:
1st number = 3(100) + 2(10) + 4(1) = 324
2nd number = 4(100) + 3(10) + 4(1) = 434
The sum of these two numbers is = 324 + 434 = 758
i.e. equal to the original sum of all blocks.
This way changing the number of blocks in each place value, different 3 digit numbers can be generated.
Answer:
The missing reason is Subtraction Property of Equality.
Step-by-step explanation:
⇒ (Given)
On Solving we get;
Multiplying 2 on both side we get;
⇒ (Multiplication Property of Equality)
Now Subtracting Both side by 10 we get;
⇒ (Subtraction Property of Equality)
Now Dividing both side by 3 we get;
⇒ (Division Property of Equality)
Hence the missing reason is Subtraction Property of Equality.
