Answer:
D=1/2
Step-by-step explanation:
Multiply the numbers
Subtract the numbers
Combine like terms
put 1/2 to the two parts of the equation
last but not least, simplify
There are two numbers whose sum is 64. The larger number subtracted from 4 times the smaller number gives 31. Then the numbers are 45 and 19
<h3><u>
Solution:</u></h3>
Given that, There are two numbers whose sum is 64.
Let the number be a and b in which a is bigger.
Then, a + b = 64 ------ eqn (1)
The larger number subtracted from 4 times the smaller number gives 31.
4 x b – a = 31
4b – a = 31 ----- eqn (2)
We have to find the numbers.
So, from eqn (2)
a = 4b – 31
Subatitute a in (1)
4b – 31 + b = 64
On solving we get
5b = 64 + 31
5b = 95
b = 19
So, b = 19, then eqn 1
a + 19 = 64
On simplification,
a = 64 – 19
a = 45
Hence, the two numbers are 45 and 19
Answer:
the answer to what?
Step-by-step explanation:
Answer:
40
Step-by-step explanation:
6x7-8/4 =42 - 2 = 40
There are many ways to work this out. One way could be:
Add up:
1/4 + 1/4 + 1/4 = 3/4
Find 3/4 of 8 so;
8 / 4 = 2
2 x 3 = 6
Find what's remaining:
8 - 6 = 2
So Mr.Greg has sandwiches left.
Hope it helped :)
