Can someone please help me solve this question 17a + 1b - 7a + 3b + 17

tangare [24]

Answer:

10a + 4b + 17

Step-by-step explanation:

Combine like terms (terms with the same amount of variables & same variables). Reorder the terms:

17a - 7a + 1b + 3b + 17

(17a - 7a) + (b + 3b) + 17

10a + 4b + 17

10a + 4b + 17 is your answer.

Answer:

The solution of $\frac{1}{4}x \leq 2$ is $\mathbf{x\leq 8}$

Graph of the solution is attached in the figure below.

Step-by-step explanation:

We need to the graph the solution of $\frac{1}{4}x \leq 2$

First we will solve to find value of x

$\frac{1}{4}x \leq 2$

Multiply both sides by 4

$\frac{1}{4}x\times 4 \leq 2\times 4 \\x\leq 8$

So, the solution of $\frac{1}{4}x \leq 2$ is $\mathbf{x\leq 8}$

Graph of the solution is attached in the figure below.

The graph contains both number line and on graph paper also.

The equation y = kx represents a proportional relationship between x and y, where k is the constant of proportionality. For a mo

valentinak56 [21]

Answer:

Step-by-step explanation:

y = kx represents a proportional relationship between x and y

where,

k is the constant of proportionality

Given:

d = st

Where,

d = distance

s = speed

t = time

The constant of proportionality of the quantities d, s and t is speed(s)

Speed(s) remains constant at a given time and distance

The equation can be written in different forms below:

d = st

S = d/t

t = d/s

Real world example of proportional relationships

• F=ma

Where,

F=Force

m=mass

a=acceleration

F=ma is used to calculate force

Three red rods are 2cm longer than two blue rods. Three blue rods are 2cm longer than four red rods. How long is each rod?

nydimaria [60]

Answer:

The length of each red rod is 10 cm and the length of each blue rod is 14 cm

Step-by-step explanation:

Let

x ----> the length of each red rod in centimeters

y ----> the length of each blue rod in centimeters

we know that

$3x=2y+2$ ----> equation A

$3y=4x+2$ ----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is the point (10,14)

see the attached figure

therefore

The length of each red rod is 10 cm and the length of each blue rod is 14 cm
