Answer 1

Answer: The correct answer is B, 8(9 + 3/4). The question asked for an expression that represents 8 times the sum of 9 and 3/4. The sum of 9 and 3/4 can be written as 9 + 3/4, and to multiply it by 8, we have to put it in parentheses. In PEMDAS (parentheses, exponents, multiplication and division, addition and subtraction) multiplication comes first, so if we left out the parentheses, we would be adding 72 to 3/4, since we multiply 8 and 9 first.

Hope this helps!

You roll a number cube. You roll a number that is greater than 2 but less than 5.

Answers

The possible number you rolled is 3 and 4
The number you rolled must the larger than 2 which is 3, 4, 5, 6, on a cube, but it must be less than five so the possible number is 3 and 4.

The cost of a ticket to the circus is $19.00 forchildren and $42.00 for adults. On a certain day,
attendance at the circus was 1,700 and the total
gate revenue was $55,300. How many children and
how many adults bought tickets?

Answers

Answer:

The number of tickets bought is 1000 adults tickets and 700 children were present

Explanation:

Let the number of children and adults present in the circus be x and y respectively

According to question,

Then, x + y = 1700 ……………..equation (1)

And, cost of ticket to circus for children and adult be 19, 42 respectively

Totalcost of ticket;

for adults = 42y; for children = 19x

19x + 42y = 55300 …………………equation (2)

Multiplying equation (1) by 19

19x + 19y = 32300 ……………… eqn (3)

Subtracting equation 1 and 3, we get

23y = 23000

y = 1000

putting this value in eq (1), we get x = 700

Therefore, 1000 adults and 700 children were present.

rita is hiking along a trail that is 13.7 miles long. so far she has hiked along 1/10 of this trail. how far has Rita hiked?

Answers

Answer

Find out the how far has Rita hiked .

To prove

Let us assume that the rita hiked distance be x.

As given

rita is hiking along a trail that is 13.7 miles long.

she has hiked along $(1)/(10)$ of this trail.

Than the equation becomes

$x = (1* 13.7)/(10)$

x = 1.37 miles

Therefore Rita hiked 1.37 miles of the a trail that is 13.7 miles long.

Answer:

Rita hiked 1.37 miles of the trail

Laura wrote and solved the following expression to find the total number of beads Lina has if there are 6 beads in each packet. Find and correct Laura’s mistake7+4b = 11b
= 11(6)
=66

Answers

The number of beads lina has is 31

Laura made a mistake by adding the constant 7 and variable 4b

Solution:

Given that,

Laura wrote and solved the following expression to find the total number of beads Lina has

There are 6 beads in each packet

7+4b = 11b

= 11(6)

=66

From given,

Lina has a total of 7 + 4b beads

Given that, There are 6 beads in each packet

Substitute b = 6

7 + 4(6)

Simplify

7 + 24

Add

Thus, she has a total of 31 beads and not 66 beads

Laura made a mistake by adding the constant 7 and variable 4b
