on Saturday Leo and his brother drove into town to visit their mom Leo is trying to remember how much he spent on gas and tolls tolls were a dollar $1.75 each and he also spent $28 at the gas station to fill up what are the terms and their factors and coefficients of the algebraic expression that represents the total cost of gas and tolls

Answers

Answer 1
Answer:

Let t be the number of tolls they crossed.

Amount they spent at each toll = $1.75.

Amount they spent at gas station = $28.

Let C be the total amount they spent on gas and tolls.

If they crossed 1 toll, then

C = 28 + 1.75(1).

If they crossed 3 tolls, then,

C = 28 + 1.75(3)

If they crossed t tolls, then,

C = 28 + 1.75t

Here, the terms are 28 and 1.75t and the factors are 1.75 and t.

How do you find the value of x for this figure?

Answers

The 2 lines intersect, and by definition it will create equal opposite angles.  Since we know that the angle created is 125 degrees, then the angle on the opposite side also must equal 125 degrees.  But wait, they broke up the angle into 2 angles made up of a 64 degree angle and an X degree angle.  These 2 angles must add up to 125 degrees.

x + 64 = 125
x = 125 - 64
x = 61 degrees

Which expression represents '' 6 more than x''

Answers

x + 6

It is 6 units larger than x so it is equal to x plus 6 (x + 6)
It is 6 units greater than x so its equivalent to x + 6

The only tricky thing about this problem is that you have to know
the formula for the area of a triangle.  The formula is

         Area of a triangle = (1/2) times (length of the base) times (the height) .

In this picture, 'x' is the base, and 'h' is the height.  That's all you need
in order to find the area.  You don't need to know 'y' or 'z' at all.

       Area = (1/2) x (base) x (height)

               = (1/2) x (13) x (6)

               = (1/2) x ( 78 )   =   39 inches²
multiply 13*6=78 then multiply with .5 (78*.5=39)

2+2=5 does anyone know how that is and don't say it isn't I want to see what you say

Answers

Actually I have no clue maybe because they arent smart or wasn't thinking straight at the time. 
2 + 2 = 4

2 + 2 = 5 is simply impossible and illogical!!

Perhaps maybe if it were part of a bigger & more complex equation and somehow 2 = 3, THEN it would make sense.

5r + 15 = 0 ........?

Answers

Answer:

r = -3

Step-by-step explanation:

Simplifying

5r + 15 = 0

Reorder the terms:

15 + 5r = 0

Solving

15 + 5r = 0

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '-15' to each side of the equation.

15 + -15 + 5r = 0 + -15

Combine like terms: 15 + -15 = 0

0 + 5r = 0 + -15

5r = 0 + -15

Combine like terms: 0 + -15 = -15

5r = -15

Divide each side by '5'.

r = -3

Simplifying

r = -3

Answer: R would equal -3

Step-by-step explanation:

5 x -3 = -15

-15 + 15 = 0
