The equation that can be used to determine the price of each gallon of gas is 8.4x = 23.94.

Given

Evelyn bought 8.4 gallons of gas for $23.94.

<h3>What is a system of equations?</h3>

A system of linear equations is a collection of two or more linear equations.

Let, the price of the gas be x.

Then,

The equation that can be used to determine the price of each gallon of gas is;

\rm \text{The amount of gas bought  = Price of each gallon gas}\times  amount \ of \ gas\\\\8.4\times x= 23.94 \\\\8.4x=23.94

Hence, the equation that can be used to determine the price of each gallon of gas is 8.4x = 23.94.

A mathematics Teacher brought 40 expensive calculator at 16400 each and a number of cheaper calculator costing tshs 5900 each. S
Novay_Z [31]

Answer:

20

Step-by-step explanation:

First, let's find how much she spent on the expensive calculators

40 times $16400= $656,000

Now, lets find how much money she had for the cheap calculators.

$774,000- $656,000=$118000

Now that we have her budget (money remaining) for the cheaper calculators, lets divide that by the price for each individual calculator.

$118000/$5900=20

Put these points into an equation IN STANDARD FORM!!!!!!<br><br>(0,2) and (8,0)
zubka84 [21]

The equation of the line in standard form is x + 4y = 8

<h3>How to determine the line equation?</h3>

From the question, the points are given as

(0, 2) and (8, 0)

To start with, we must calculate the slope of the line

This is calculated using

Slope = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) = (0, 2) and (8, 0)

Substitute the known parameters in Slope = (y₂ - y₁)/(x₂ - x₁)

So, we have

Slope = (0 - 2)/(8 - 0)

Evaluate

Slope = -1/4

The equation of the line can be calculated using as

y - y₁ = m(x + x₁)

Where

(x₁, y₁) = (0, 2)

and

m = slope = -1/4

Substitute the known values in the above equation

So, we have the following equation

y - 2 = -1/4(x - 0)

This gives

y - 2 = -1/4x

Rewrite as

1/4x + y = 2

Multiply by 4

x + 4y = 8

Hence, the line has an equation of x + 4y = 8

WILL GIVE 10 POINTS Leona was using an eyedropper to place droplets in a small container.
il63 [147K]

Answer:

A. milliliters     B. 8 fluid ounces

Step-by-step explanation:

An eyedropper is very small and can only hold a small amount.  You can eliminate 2 from the start: millimeter and meter.  These two are use for measuring distance not volume.  ex.) I walked 2 meters.  A liter is too big for an eyedropper.  ex.) 1 liter of soda.

A glass full of juice would be 8 fuild ounces because a glass is basically a cup.  A 8 gallons is too big, and a 8 tablespoons is too small.  ex.) gallon of milk and tablespoon of sugar.  8 cups is too big because a glass is about 1 cup.  8 fluid ounces = 1 cup

Small squares with sides 4 cm were cut from each of the corners of a square piece of cardboard. then it was folded into an open-
DENIUS [597]
Suppose the length of the card board was x cm by x cm
After squares of 4cm was cut from the corner, the dimension for the box will be:
length=(x-8) cm
width=(x-8) cm
height=4 cm
thus the volume will be:
V=length*width*height
V=4×(x-8)×(x-8)=144
x²-16x+64=36
this can be simplified to form a quadratic equation given by:
x²-16x+28=0
solving the quadratic equation we get:
x=2 or x=14
Thus we conclude that the original dimensions was:
length=14 cm ; width=14 cm
