Solve For X In The Figure Below 3x-121 167

Answers

Answer 1

Answer:

49

Step-by-step explanation:

167 = 21 + (3x - 1)

167 = 20 + 3x

3x = 147

x = 49

Answer 2

Answer is 49

Step-by-step explanation:

167=(3x-1)+21(Exterior angle is equal to two opposite interior angle)

or,167=3x-1+21

or,167=3x+20

or,167-20=3x

or,147=3x

or,x=147/3

or,x=49

A car covers a distance of 60 km in 3 hours. However, for the first 40 km it travels 16 km/hr. At what speed must it travel for the rest of the distance in order to complete the journey on time?

Answers

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

LOTS OF POINTS
answer the question down below correctly
thanks

Answers

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

y= X + 2

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

What is an expression?

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".

What is an expression?

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.
