If 4x - 3 = 5, then x=

Answers

Answer 1

Answer:

Answer:

x=2

Step-by-step explanation:

4x-3=5

4x-3 plus 3 and 5 plus 3

4x=8

Divide both sides by 4

x=2

Answer 2

Answer:

Answer:

X = 2

Step-by-step explanation:

This is how I got the answer:

Move constant to the right-hand + change signs

4x = 5 + 3

add

4x =5 + 3

4x = 8

Divide by both sides to get the answer of;

X = 2

An albatross is a large bird that can fly 600 kilometers in 15 hours at a constant speed. Using LaTeX: dd for distance in kilometers and LaTeX: tt for number of hours, an equation that represents this situation is LaTeX: d=40td = 40 t . What are two constants of proportionality for the relationship between distance in kilometers and number of hours?

Answers

Answer:

The constant is 40

Step-by-step explanation:

According to the question we are given an equation that represents the given situation as d = 40t where;

d is the distance in km

t is the time in seconds.

The given function is a direct proportionality. For example if p is directly proportional to q, this is expressed as p ∝ q where ∝ is the proportionality sign. In order to remove the sign we will introduce a constant say "k". The equation will become;

p = kq (p and q are the variables)

A direct proportionality means that as a variable is increasing, the other is increasing and vice versa. Comparing p = kq with d = 40t, we can see that k is equal to 40 and d is directly proportional to t

Hence the constants of proportionality for the relationship between distance in kilometers and number of hours is 40 on comparing.

What is the distance between point A and point B? A number line ranging from negative 8 to 8 with point A at coordinate negative 6 and point B at coordinate 7 Enter your answer in the box. The distance between points A and B on the number line is units. help please unit # 1 question 10 PLZZZZZ !!!!

Answers

The distance between point A and B is 13 units

what is number line?

A number line can be defined as a straight line with numbers placed at equal intervals or segments along its length.

As, per the number line given we have A at (-6) and B at (+7).

So, not considering the negative sign we have 6 at left of 0 and 7 at right side of zero in a number line.

So, the distance will be

= 6 +7

=13 units

HeLpPLZZZ (Edge). Which line on the graph represents the information in the table? Cost of Pencils Number of Pencils Total Cost (in $) 2 0.50 4 1.00 6 1.50 8 2.00 On a coordinate plane, the x-axis is labeled Number of pencils and the y-axis is labeled total cost in dollars. Line a goes through points (1, 4) and (2, 8). Line b goes through points (1, 2) and (2, 4). Line c goes through (2, 1) and (4, 2). Line d goes through (4, 1) and (8, 2). line a line b line c line d

Answers

Answer:

Line D- (4, 1) and (8, 2).

Step-by-step explanation:

The table representing the information is given below:

$\left|\begin{array}{c|c}$Number of Pencils(x)&$Total Cost(in $)(y)\n----&----\n2&0.50\n4&1.00\n6&1.50\n8&2.00\end{array}\right|$

On the coordinate plane, the x-axis is labeled Number of pencils and the y-axis is labeled total cost in dollars.

Therefore, any point that matches with the (x,y) pair on the table represents the information in the table.

Only Line D matches with the pair (4,1) and (8,2)

By the Definition of congruent property, we have proved that:

VW ≅ VX

Congruent Property:

The three properties of congruence are the reflexive property of congruence, the symmetric property of congruence and the transitive property of congruence. These properties can be applied to line segments, angles, triangles, or any other shape.

Given: VZ ≅ VY and WY ≅ XZ

Prove: VW ≅ VX

Proof:

(Given): VZ ≅ VY and WY ≅ XZ

By the Definition of Congruent Substitute:

VZ = VY and WY = XZ

⇒ VZ = VX + XZ , and,

VY = VW + WY

By Substituting

VX + XZ = VW + WY

Again,

VX + WY = VW + WY
