Trina spent $30 for general admission at an amusement park. Each ride cost $2.50. She spent a total of $67.50. What arithmetic steps can you use to find how many rides Trina rode?
A. Divide 67.5 by 2.5, add 30 to the quotient.
B. Add 67.5 and 30, divide the sum by 2.5.
C. Subtract 30 from 67.5, divide the difference by 2.5.
D. Multiply 30 by 2.5, subtract 67.5.

The mathematical expression is 6 + 8x

The sum of 6 and the product of 8 and x  can be written  mathematically by first  getting the product of  8 and x  which equals 8x

Sum means addition( +)

Answer:

b.

Sacramento School has 1650 students

Ronald E School has 1800 students

c.

Apple Pies cost $4 each

Black Berry Pies cost $19 each

Step-by-step explanation:

b.

Let "x" students attend Sacramento School, and

"y" students attend Ronald E. School

It is given that Sacramento School has 150 fewer students than Ronald E School, so we can write:

x + 150 = y

And,

Total number of students in 2 schools is 3450, we can write:

x + y = 3450

We put Equation 1 in Equation 2 and solve for x first:

Now, we know y = x + 150, y = 1650 + 150 = 1800

So, Sacramento School has 1650 students

Ronald E School has 1800 students

c.

Let apple pies cost "x" and blackberry pies cost "y" each

Gabriella sold 10 apples pies and 12 blackberry pies for total 268, so we can write:

10x + 12y = 268

Also,

Mary sold 14 apple pies and 4 blackberry pies for 132, so we can write:

14x + 4y = 132

Let's multiply Equation 2 with -3, to get:

-3 [14x + 4y = 132]

= -42x - 12y = 396

Lets add this equation to equation 1:

10x + 12y = 268

-42x - 12y = -396

------------------------

-32x = -128

x = -128/-32

x = 4

Now, plugging in x = 4 into 1sst equation, we can solve for y:

10x + 12y = 268

10(4) + 12y = 268

40 + 12y = 268

12 y = 228

y = 228/12

y = 19

So,

Apple Pies cost $4 each

Black Berry Pies cost $19 each

Answer:

To bring the submarine back to the sea level, it have to move 578 feet upwards

Step-by-step explanation:

Given:

Initially the depth the submarine dives  =  657 feet below sea

The height the submarine moves up =  79 feet

To Find :

Change in its depth required to bring the submarine back to the sea level  = ?

Solution :

In initially the Submarine will be at the depth of  657 feet below sea

when it goes up, the the depth reduces

657 - 79  = 578 feet

Now the submarine will be the depth of  578 feet

Now the submarine have to move  578 feet upwards to reach the sea level

Answer:

19.73.

Step-by-step explanation:

Given : 19 - 1.67 + (2.4).

To find : simplify.

Solution : We have given  19 - 1.67 + (2.4).

By the BODMAS rule  :

First we open the parenthesis

19 - 1.67 + 2.4

Now we solve the addition operation

19+2.4 -1.67

21.4 -1.67.

Now we will solve the subtraction operation :

19.73.

Therefore, 19.73.
