nlexa [21]

Answer:

The price of one pound of coffee is 32 pesos

The price of one pound of sugar is 7 pesos

Step-by-step explanation:

The question in English is

6 pounds of coffee and 5 pounds of sugar cost 227 pesos and 5 pounds of coffee and 4 pounds of sugar (at the same prices) cost 188 pesos Find the price of one pound of coffee and one pound of sugar.

Let

x-----> the price of one pound of coffee

y-----> the price of one pound of sugar

we know that

6x+5y=227 -----> equation A

5x+4y=188 ----> equation B

Solve the system of equations by graphing

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

The solution is the point (32,7)

see the attached figure

therefore

The price of one pound of coffee is 32 pesos

The price of one pound of sugar is 7 pesos

musickatia [10]

Complete question :

The Daily Info charges a fee $650 of plus $80 per week to run an ad. The People's Paper charges $145 per week. Write an inequality to represent the number of weeks an ad must run for the total cost at the Daily Info to be less expensive than the cost at the People's Paper. Let w be the number of weeks the ad runs in the paper

Answer:

650 + 80w < 145w

Step-by-step explanation:

Given that :

Number of weeks ad will run = w

Daily Info total cost :

650 + 80w

The People's Paper total cost:

145w

Number of weeks ad should run For cost at daily info to be less expensive than peoples choice';

Daily Info total cost < people's choice

650 + 80w < 145w

650 < 145w - 80w

650 < 65w

650/65 < 65w / 65

10 < w

w > 10

Examine this system of equations. Which numbers can be multiplied by each equation so that when the two equations are added toge

In the elimination method one variable is eliminated from the system of equation to find the value of other.

The first equation must be multiplied by 18 and second equation must be multiplied by 8.

<h3>What is elimination method?</h3>

To solve the system of equation and find the value of the variables, the elimination method is used.

In this method one variable is eliminated from the system of equation to find the value of other.

Given information-

The system of equation given in the problem is,

$\dfrac{1}{4}x -\dfrac{1}{6}y =5\\$ ......1

Let the above equation as equation 1.

The second equation given in the problem is,

$\dfrac{4}{5}x +\dfrac{3}{8}y =10$ ......2

Let the above equation as equation 2.

To eliminate the y term, make the coefficient of <em>y</em> of both the equation equal.

As the coefficient of <em>y</em> of the equation 2 is 3/8. Thus multiply second equation with 8 to eliminate coefficient. Thus,

$8\times \dfrac{4}{5}x +8\times\dfrac{3}{8}y =8\times10\\$

$\dfrac{32}{5}x +3y =80$ .....3

Multiply equation 1 with 18 to make the coefficient of y equal. Thus,

$18 \times\dfrac{1}{4}x -18\times\dfrac{1}{6} \times y =18 \times5$

$\dfrac{18}{4}x -3 =90$ ......4

Add equation 3 and equation 4 as,

$\dfrac{32}{5}x +3y+ \dfrac{18}{4}x -3y =80+90$

$\dfrac{32}{5}x + \dfrac{18}{4}x =170$

Hence the first equation must be multiplied by 18 and second equation must be multiplied by 8.

Rus_ich [418]

Answer:

Rabies illustrates a negative consequence to otherwise healthy retrograde flow within axons. Which of the following components will not be involved in retrograde flow?

(i) Kinesin

(ii) Axon hillock

(iii) Neuronal cell body

(iv) Axoplasm

(i) Kinesin

Step-by-step explanation:

Description of the functions of the other options

Axon hillock

axon hillock or initial segment is the region where the nerve impulses are generated by the plasma membrane

Neuronal cell body

survival signals are carried by retrograde transport from the synapse back to the cell body, such as the TRK (tyrosine kinases), the nerve growth factor receptor.

Axoplasm

Axonal transport, or axoplasmic flow, or axoplasmic transport is a cellular process that is responsible for the movement of synaptic vesicles, lipids, mitochondria and proteins both towards and away from the cell body of a neuron, via the cytoplasm

Kinesin

A kinesin is a protein that belongs to a family of motor proteins present in eukaryotic cells.
