I need help badly plz

Answer:

So let’s say I have 5 as well

triple of 5 is 5,10,15

15+5=20

my friend has 20 comic books

and I have 5

Step-by-step explanation:

brainlyest please

The expression represents the number of comic books a friend has is F = 3c + 5.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given,

A friend has 5 more than triple c

Suppose a friend has an "F" number of comic books then,

F = 3c + 5

Hence "F = 3c + 5 is an expression that indicates how many comic books a friend owns".

Answer:

31.17

Step-by-step explanation:

P = 4s (the sum of the four sides, which are equal)

A = s²

22 1/3 = 4s

67/3 = 4s

s = 67/12

A = (67/12²

A = 4489 / 144 = 31 25/144 or 31.173611111 ≈ 31.17

Answer:

y = 1x + 2

Step-by-step explanation:

To fill in slope intercept form(y = mx + b) identify the initial value(b) and slope(m).

The initial value is the y coordinate when the x coordinate is 0. It is also known as the point where the line crosses the y axis. This point on the graph is (0, 2). So, the initial value is 2.

Slope is identified by finding a point on the graph that the line passes through and creating a right triangle to a point that is even with both point. Then, divide the y coordinate of that point by its x coordinate. One coordinate you could use is point (-2, 2). 2 divided by -2 is -1. But, since the line has a positive association, the slope is going to be a positive number. So, the slope is 1.

Now fill in the the slope intercept form.

y = mx + b ---> y = 1x + 2

Answer:

y= X + 2

Step-by-step explanation:

Polynomials are closed under an operation if it produces a polynomial.

5x⁴, x² + 2x + 1 and x³ - 10x³ + 28x - 15

are all polynomials of x.

x - 3 + (-3)/(x - 2) is not a polynomial because x can be found in the denominator of a fractional term.

The answer is Option A.

Answer:

Step-by-step explanation:

the mat will be b. 4ft

The new length of the mat will be 4 ( 7 / 12). The correct option is A.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the length of the mat is 5 ( 1 / 4 ) and the length cut by 2 / 3  feet. The new length will be calculated as below:-

New length = 5 ( 1 / 4 ) - ( 2 / 3 )

New length = ( 21 / 4 )  - ( 2 / 3 )

New length = ( 63 - 8 ) / 12

New length = ( 55 ) / 12

New length = 4 ( 7 / 12 )

Therefore, the new length of the mat will be 4 ( 7 / 12). The correct option is A.

Answer:

40 km/hr

Step-by-step explanation:

Given that:

Total distance covered in 3 hours = 60km

Speed during first 40 km = 16km/hr

Hence, time spent during the first 40 km ;

Recall:

Time = distance / speed

Time = 40 / 16

Time = 2.5 hours

Hence, speed required to cover the remaining (60 - 40) = 20km in (3 - 2.5) hours =0.5 hours

Speed = distance / time

Speed = 20 / 0. 5

Speed = 40 km / hr
