Abby bought 3 sweaters that each cost the same amount and 1 skirt that cost $15. The items she bought cost a total of $90 before tax was added. Determine which equation could be used to find, x, the cost of each sweater.
A 3x - 15 = 90
B 3x + 15 = 90
C 15 - 3x = 90
D 15x + 3 = 90
Answer:
B
x is the price of the sweater so 3x and add $15 for the skirt which would add up to $90
Answer:
3x + 15 = 90

There are 20 blue dye 6 red dye and 14 green dye what is the probability of me selecting the green dye
90 points!
Answer:
35%
Step-by-step explanation:
14 green / 40 total
Answer:
[tex]\boxed {\boxed {\sf \frac{7}{20} \ or \ 35 \% }}[/tex]
Step-by-step explanation:
Probability tells us how likely something is to occur. It is found by dividing the favorable outcomes by the total outcomes.
[tex]P=\frac{favorable \ outcomes}{total \ outcomes}[/tex]
In this question, a favorable outcome is selecting a green dye. The total outcomes are all the dyes.
Favorable outcomes (green dye): 14 Total outcomes (all dyes): 20 blue+ 6 red+14 green=40[tex]P(green \ dye)=\frac{14}{40}[/tex]
Reduce the fraction. Both the numerator and denominator can be divided by 2.
[tex]P(green \ dye) =\frac{14/2}{40/2}[/tex]
[tex]P (green \ dye)=\frac {7}{20}[/tex]
This is the probabilty as a fraction. It can also be written as a percent. Divide the fraction, then multiply by 100.
[tex]P(green \ dye)=\frac{7}{20}*100[/tex]
[tex]P(green \ dye)=0.35 *100[/tex]
[tex]P(green \ dye)=35 =35 \%[/tex]
The probablity of selecting a green dye is 7/20 or 35%

Find the amount of savings in each instance
Answer:
See belowStep-by-step explanation:
Use formula:
P*(1 + r/n)^(nt)P- invested amount, r- interest rate, n- number of compounds a year, t- number of yearsQ1. r = 5% = 0.05, n = 2, t = 1
$1000*(1 +0.05/2)^2 = $1050.63Q2. r = 5% = 0.05, n = 4, t = 1
$1000*(1 + 0.05/4)^4 = $1050.95Q3. r = 5% = 0.05, n = 4, t = 2
$1000*(1 + 0.05/4)^8 = $1104.49Q4. r = 8% = 0.08, n = 1, t = 3
$1000*(1 + 0.08)^3 = $1259.71Q5. r = 8% = 0.08, n = 4, t = 3
$1000*(1 + 0.08/4)^12 = $1268.24Note: All results rounded to the nearest cent

Solve the inequality
what is the solution?
Answer:
The solution to the inequality is:
[tex]2\ge \frac{g}{-4}\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:g\ge \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:[-8,\:\infty \:)\end{bmatrix}[/tex]
Please also check the graph of the solution to the inequality.
Step-by-step explanation:
Given the inequality
[tex]2\ge \frac{g}{-4}[/tex]
switch sides
[tex]\frac{g}{-4}\le \:2[/tex]
Multiply both sides by -1 (reverse the inequality)
[tex]\frac{g\left(-1\right)}{-4}\ge \:2\left(-1\right)[/tex]
Simplify
[tex]\frac{g}{4}\ge \:-2[/tex]
Multiply both sides by 4
[tex]\frac{4g}{4}\ge \:4\left(-2\right)[/tex]
Simplify
[tex]g\ge \:-8[/tex]
Therefore, the solution to the inequality is:
[tex]2\ge \frac{g}{-4}\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:g\ge \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:[-8,\:\infty \:)\end{bmatrix}[/tex]
Please also check the graph of the solution to the inequality.

Answer:
ABC
Step-by-step explanation:
Sum numerelor m si n este 350.Numarul n este de 6 ori mai mare decat m.Afla valoarea fiecarui numar.
Răspuns:
m = 50; n = 300
Explicație pas cu pas:
Dat fiind:
Suma numerelor m și n = 350; acesta este ;
m + n = 350 - - - (1)
n este de 6 ori mai mare decât m; acesta este ;
n = 6m - - - (2)
Înlocuind n = 6m în (1)
Astfel ecuația (1) devine
m + 6m = 350
7m = 350
m = 350/7
m = 50
n = 6m
n = 6 * 50
n = 300

Two snakes race the speed of the first is 24 1/2 inches per minute and the speed of the other is 26 inches per minute how far apart with they be in 3 min? 10 min?
Answer:
637, 245
Step-by-step explanation:
Speed is the rate of change in the position of an object. The distance between the two snakes after 10 mins is 15 inches.
What is the relation between speed, distance, and Time?We know that sped, distance, and time all are in a relationship to each other. this relationship can be given as,
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
Given to us
Two snakes race The speed of the first is 24 1/2 inches per minute The speed of the other is 26 inches per minute What is the distance between them after 3 mins?The relative speed between them, as they are moving in the same direction, therefore,
Relative speed = (26-24.5) = 1.5 inches per minute
[tex]\text{Distance between them after 3 mins}= \rm speed \times \rm time[/tex]
[tex]= 1.5 \times 3\ mins\\= 4.5\ inches[/tex]
Thus, the distance between the two snakes after 3 mins is 4.5 inches.
What is the distance between them after 10 mins?The relative speed between them, as they are moving in the same direction, therefore,
Relative speed = (26-24.5) = 1.5 inches per minute
[tex]\text{Distance between them after 10 mins}= \rm speed \times \rm time[/tex]
[tex]= 1.5 \times 10\ mins\\= 15\ inches[/tex]
Thus, the distance between the two snakes after 10 mins is 15 inches.
