Step-by-step explanation:

Given that,

Mya has 3 times as much floor as Eric. Mya has 15.81 lb of floor. The relation is given by :

Let Eric has F floor.

3F = 15.81 ...(1)

F = 15.81/3

F = 5.27 lb

Hence, Eric has 5.27 lb of flour.

Martin is not correct.

Calculating Temperature

From the question, we are to determine the afternoon temperature in Westfield City

From the given information,

"In the morning, the temperature in Westfield City was -2°F"

and

"By afternoon, a north wind caused the temperature to drop another 8°F"

James works in a sporting goods store and earns $324 a week and 5% of his sales. One week James earned $432. What were his sales that week?

Answers

Answer:

His sales that week were $2,160.

Step-by-step explanation:

First, you have to subtract $324 from the amount he earned that week, to find the 5% he got from sales:

$432-$324=$108

Now, you know that he received $108 that represent 5% of his sales and you can use a rule of three to find the amount that represents 100% which would be his sales that week:

5% → 108

100% → x

x=(100*108)/5=2160

According to this, the answer is that his sales that week were $2,160.

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 6, 4, 8/3... Find the 7th term.

Answers

Answer:

0.527

Step-by-step explanation:

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 6, 4, 8/3... Find the 7th term

The sequence given in the above Question is a geometric sequence.

The formula for the nth term of a geometric sequence is given as:

an = a × r ^n - 1

Where

a = First term

r = Common ratio

n = nth term

From the above question, we are asked to find the 7th term

Hence:

a = 6

Common ratio = Second term/first term

= 4/6 = 2/3

n = 7

The 7th term = 6 × (2/3 )^7 - 1

= 6 × (2/3)^6

= 6 × (2/3)⁶

= 0.5267489712

Approximately to the nearest thousandths the 7th term = 0.527

The equation of a straight line is y = 20 – X.
If the x value of a point on the line is 14, what is the y value of this point?

Answers

Given:

The equation of a straight line is

[tex]y=20-x[/tex]

The x value of a point on the line is 14.

To find:

The y value of this point.

Solution:

If a point (x,y) lines on line, then the equation of line must be stratified by that point.

We have, the equation of a straight line.

[tex]y=20-x[/tex]

Putting x=14, we get

[tex]y=20-14[/tex]

[tex]y=6[/tex]

Therefore, the y-value is 6 when the x-value is 14.

A drummer and a guitarist each wrote songs for their band. The guitarist wrote 5 fewer than three times the number of songs that the drummer wrote. They wrote a total of 35 songs. Which system of equations models this situation if the drummer wrote d songs and the guitarist wrote g songs? *

Answers

Answer:

Guitarist wtote 25 songs

Drummer wrote 10 songs

Step-by-step explanation:

G: number of guitarist songs

D: number of Drummer songs

We have:

G=3D - 5 (The guitarist wrote 5 fewer than three times the number of songs that the drummer wrote)

G+D=35 (They wrote a total of 35 songs)

That is the meaning of each equation.

Now we have to solve these system of equations:

G=3D-5

G+D=35

Using the substitution method:

(3D-5)+D=35

4D=35+5

4D+40

D=10

Thus: G=35-10

G=25
