Answers
It is recommended that the expressions
d = 400 - 256 and
d = 256 - 400 be considered when attempting to determine how much farther Adam can see to the horizon.
The calculation for the expression is as follows:Since, the eye-level height of Pam is 256 feet above sea level, whereas the eye-level height of Adam is 400 feet above sea level.
Therefore, the formula that indicates how much farther Adam can see to the horizon should be taken to be
d = 400 - 256 and
d = 256 - 400.
This expression may be found by subtracting 400 from 256.

Answers
Let’s do x
To isolate x in equation 2, we subtract y from both sides to get
X=-12-y
Now we know what x is in terms of y and an integer.
Plug back in
2(-12-y)-3y=6
-24-2y-3y=6
-24-5y=6
-5y=30
y=-6
We have the value of y now.

which are the partial products of 3,706×4?
Answers
The partial products of 3706 × 4 is ( 3000 × 4 ) + ( 706 × 4 ).
Calculating the product of two or more numbers is the procedure known as multiplication in mathematics. When two integers are multiplied together in mathematics, the result is a product or an expression that describes the factors to be multiplied.
The decimal numeral system is widely used to express both integer and non-integer numbers. The way of representing numbers in the decimal system is known as decimal notation.
The given product is 3706 × 4 and can be written as:-
3706 × 4 = [ 3000 + 706 ] × 4
3706 × 4 = ( 3000 × 4 ) + ( 706 × 4 )
Therefore, the partial products of the given expression is ( 3000 x 4 ) + ( 706 x 4 ).

Mariana owns a food truck and sells tacos and burritos. Each taco costs $2.50 and each burrito costs $4.00. Th
system of equations represents the results of Mariana's sales yesterday for t tacos and b burritos.
t + b = 60
2.50t + 4.00b = 175.50
How many tacos did Mariana sell yesterday?
Answers
Let the cost of one tacos = t
Let the cost of one burritos = b
So, we have this system
t + b = 60 (eq-1)
2.50t + 4.00b = 175.50 (eq-2)
We take equation-1,
We can write,
t + b = 60
t= 60-b (eq-3)
Substitute equation-3 into equation-2,
We can write,
2.50t + 4.00b = 175.50
2.50(60-b) + 4.00b = 175.50
Multiply the values,
2.5(60)-2.5b+4b = 175.5
150-2.5b+4b = 175.50
Subtract the values,
1.5b = 175.5-150
1.5b = 25.5
b = 25.5/1.5
Divide the values,
b = 17
Replace the value 'b' in equation-3,
We can write,
t= 60-b
t= 60-17
t=43
Therefore,
Mariana sell 43 tacos yesterday.

Marty placed $4000 into an account earning 4% simple interest. At the end of the year he moved the total amount to a new account earning 5% interest. Determine the amount of money Marty would have at the end of the second year.
Answers
Simple interest , 4368 is the amount of money Marty would have at the end of the second year.
What does the term "simple interest" mean?
Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.P = $4000 R = 4% T = 1
then substitute the value into the formula = [tex]\frac{P * R * T }{100}[/tex]
= [tex]\frac{4000 * 4 * 1}{100}[/tex] = 160
So, the total amount is ( 4000 + 160) = 4160
Second year
P = 4160 , R = 5% T = 1
then substitute the value into the formula = [tex]\frac{P * R * T }{100}[/tex]
= [tex]\frac{4160 * 5 * 1}{100}[/tex] = 208
So, the total amount is ( 4160 + 208 ) = 4368

if f (x) =x2-4x-6 find f(o) F(3) f(-2) show that f (1/2) f(7/2) and f(2-h) f (2+h)
Answers
If f(x) = x² ₋ 4x ₋ 6 then we get the following answers for f(0),f(3) and f(-2) respectively. And the expression f(1/2) = f(7/2) and f(2₋h) = f(2₊h) is therefore proved.
f(0) = -6
f(3) = -9
f(-2) = 6
Given the function is f(x) = x² ₋ 4x ₋ 6
we need to find for f(0):
f(0) = 0² ₋ 4(0) ₋ 6
f(0) = ₋6
f(3) = 3² ₋ 4(3) ₋ 6
f(3) = 9 ₋ 12 ₋ 6
f(3) = ₋9
f(₋2) = (₋2)² ₋ 4(₋2) ₋ 6
f(₋2) = 4 ₊ 8 ₋ 6
f(₋2) = 6
we need to prove f(1/2)f(7/2)
now, f(1/2) = (1/2)² ₋ 4(1/2) ₋ 6
f(1/2) = 1/4 ₋ 2 ₋ 6
f(1/2) = 1 ₋ 8 ₋ 24 / 4
f(1/2) = ₋31/4
f(7/2) = (7/2)² ₋ 4(7/2) ₋ 6
f(7/2) = 49/4 ₋ 14 ₋ 6
f(7/2) = 49 ₋ 56 ₋ 24 / 4
f(7/2) = ₋31/4
therefore, f(1/2) = f(7/2)
f(2₋h) = (2₋h)² ₋ 4(2₋h) ₋ 6
f(2₋h) = (4 ₊ h² ₋ 4h) ₋ 8 ₊ 4h ₋ 6
f(2₋h) = h² ₊ 4 ₋ 4h ₋ 8 ₊ 4h ₋ 6
f(2₋h) = h² ₋ 10
f(2₊h) = (2₊h)² ₋ 4(2₊h) ₋ 6
f(2₊h) = 4 ₊ h² ₊ 4h ₋ 8 ₋ 4h ₋ 6
f(2₊h) = h² ₋ 10
therefore, f(2₋h) = f(2₊h)

Ken is playing with building blocks. He wants to put all 64 blocks into the same number of stacks. How many blocks could he put in each stack
Answers
Answer: He could put 8 blocks in 8 stacks
Step-by-step explanation:
Ken could put the blocks in stacks of 1, 2, 4, 8, 16, 32, or 64.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To find out how many blocks Ken could put in each stack, we need to divide the total number of blocks by the number of stacks.
So we have:
Number of blocks = 64
Number of stacks = x
To find out how many blocks can be put in each stack, we can set up the following equation:
64 / x = y
where y is the number of blocks in each stack.
Solving for y, we get:
y = 64 / x
So if Ken wants to put all 64 blocks into the same number of stacks, he can put:
64 blocks in 1 stack
32 blocks in 2 stacks
16 blocks in 4 stacks
8 blocks in 8 stacks
4 blocks in 16 stacks
2 blocks in 32 stacks
1 block in 64 stacks
Therefore,
Ken could put the blocks in stacks of 1, 2, 4, 8, 16, 32, or 64.

Therefore,15x + 9 = 21x - 27
Subtract 9 from both sides:
15x = 21x - 27 - 9
15x = 21x - 36
Subtract 21x from both sides
15x - 21x = - 36
