Answer:

291

Step-by-step explanation:

subtract 247 from 538

In general, subtract a from b is written as b-a. 'a' is get subtracted from b

subtract 247 from 538

we need to subtract 247 from the number 538

So it can be written as

$538-247=291$

When we subtract 247 from 538 we got 291

subtract 247 from 538 gives us 291

You just subtract as normal:

247 - 538 =

But since 247 is smaller than 538, your answer will be negative

247 - 538 = -291

Answer:

Step-by-step explanation:

5/8 +1/n = 7/8

1/n= -5/8 +7/8

1/n = 2/8

1/n= 1/2

then you would try to get n by itself

by dividing n/1 to 1/n and 1/2

Tickets to the zoo cost $12 for adults and $8 for children. The school has a budget of $240 for the field trip. An equation repr

Oxana [17]

Answer:

18 children

Step-by-step explanation:

Given

$240 = 12x +8y$

Required (missing part of the question):

Number of children that will be able to go to the zoo if 8 adult tickets are purchased

The graph is missing. However, the question can be solved without the graph.

From the question and equation, we can deduce the following:

x represents adults
y represents children

So, when 8 adult tickets were sold.

This means

$x = 8$

Substitute 8 for x in $240 = 12x +8y$

$240= 12 * 8 + 8y$

$240= 96+ 8y$

Subtract 96 from both sides

$240 - 96 = 96 - 96 + 8y$

$144 = 8y$

$8y = 144$

Solve for y

$y= \frac{144}{8}$

$y= 18$

This means that 18 children will be able to go

The substraction of a matrix B may be considered as the addition of the matrix (-1)B. Dose the commutative law of addition permi

GuDViN [60]

Answer: The corrected statement is A - B = -B + A.

Step-by-step explanation: Given that the subtraction of a matrix B may be considered as the addition of the matrix (-1)B.

We are given to check whether the commutative law of addition permit us to state that A - B = B - A.

If not, We are to correct the statement.

If the subtraction A - B is considered a the addition A + (-B), then the commutative law should be stated as follows :

A + (-B) = (-B) + A.

That is, A - B = -B + A.

Thus, the corrected statement is A - B = -B + A, not B - A.

Answer:

234

Step-by-step explanation:

We want to find the summation from n = 2 to n = 10 of the equation -4 + 5n.

We can use the summation formula:

$S=\frac{(a_1+a_n)*n}{2}$ , where a1 is the first term, $a_n$ is the last term, and n is the number of terms

Here, we can say the first term occurs when n = 2:

-4 + 5n

-4 + 5 * 2 = -4 + 10 = 6

The last term will be when n = 10:

-4 + 5n

-4 + 5 * 10 = -4 + 50 = 46

The number of terms is just 10 - 2 + 1 = 9 terms.

Substitute these in:

$S=\frac{(a_1+a_n)*n}{2}$

$S=\frac{(6+46)*9}{2}=\frac{468}{2} =234$

Thus, the answer is 234.
