The sum of my digits is an even number. My first digit is 6 less than my second digit. 12 is the number you get when you add my

Arte-miy333 [17]

Answer:

Step-by-step explanation:

Let a and b represent the first and second digits, respectively.

... a = b -6 . . . . . . the first digit is 6 less than the second

... a + b = 12 . . . . .the sum of digits is 12 (an even number)

Using the expression in the first equation, we can substitute for a in the second equation:

... (b -6) +b = 12

... 2b = 18 . . . . . . add 6, simplify

... b = 9 . . . . . . . . .divide by 2

... a = 9 -6 = 3 . . . . from the first equation

The number is 39.

The concept of determining which reactant is limiting and which is in excess is akin to determining the number of sandwiches tha

Alona [7]

Answer: There are 22 whole cheese sandwiches that can be prepared.

Step-by-step explanation:

Since we have given that

Number of slices of bread = 44

Number of slices of cheese = 75

According to question, a cheese sandwich consists of 2 slices of bread and 3 slices of cheese.

So, we need to find the number of whole cheese sandwiches that can be prepared.

Number of sandwich containing only slice of bread is given by

$\dfrac{44}{2}=22$

Number of sandwich containing only slice of cheese is given by

$\dfrac{75}{3}=25$

As we know that each sandwich should contain both slice of bread and slice of cheese.

So, Least of (22, 25) = 22

Hence, there are 22 whole cheese sandwiches that can be prepared.

The given expression $8(4)^2+2^4$ is equal to 144 or $12^2$

<em><u>Solution:</u></em>

Given expression is:

$8(4)^2+2^4$

We have to evaluate the above given expression

We know that,

$(4)^2 = 4 \times 4 = 16$

$2^4 = 2 \times 2 \times 2 \times 2=16$

Substituting these in above given expression, we get

$8(4)^2+2^4=8 \times 16+16\\\\8(4)^2+2^4= 128+16\\\\8(4)^2+2^4=144$

Also we know that,

$12 \times 12 = 144$

Therefore,

$8(4)^2+2^4=144 = 12 \times 12 = 12^2$

Thus the given expression $8(4)^2+2^4$ is equal to 144 or $12^2$
