Answer:
t = -19.8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex]-8.2 + \frac{t}{-2} = 1.7[/tex] [tex]-8.2 - \frac{1}{2}t = 1.7[/tex] [tex]-\frac{1}{2}t - 8.2 = 1.7[/tex]Step 2: Add 8.2 to both sides.
[tex]-\frac{1}{2}t - 8.2 + 8.2 = 1.7 + 8.2[/tex] [tex]-\frac{1}{2}t = 9.9[/tex]Step 3: Multiply both sides by -2.
[tex]-\frac{1}{2}t * (-2)= 9.9 * (-2)[/tex] [tex]t = -19.8[/tex]HELPPPP
Jen ran directly toward school at a constant velocity for 36 seconds. In one-third of that time, she ran 120 meters. What was her velocity?
Answer is 10 m/s
Step-by-step explanation:-First, we need to calculate one-third of 36 seconds :
[tex] \frac{1}{3} \times 36[/tex]
[tex] \frac{36}{3} [/tex]
[tex]12[/tex]
Now, to find velocity, let's divide the distance by time :
[tex]velocity = \frac{distance}{time} [/tex]
[tex]velocity = \frac{120}{12} [/tex]
[tex]velocity = 10 \: m/s[/tex]
Therefore, Jen's velocity is 10 m/s .

Al simplificar la expresión -3(a – b) + 5b – {2a + b + [a – 3b – (2b – a) + 5b] – a}, se obtiene:
Al simplificar la expresión-3 (a - b) + 5b - {2a + b + [a - 3b - (2b - a) + 5b] - a}, se obtiene: - (6a + 7b)
La simplificación de expresiones algebraicas requiere la eliminación de los corchetes por sus factores de multiplicación seguido de la combinación y agrupación de los términos semejantes en suma y resta.
De la información proporcionada:
= -3 (a - b) + 5b - {2a + b + [a - 3b - (2b -a) + 5b] - a}El primer paso es abrir los soportes de adentro hacia afuera.
i.e.
= -3a + 3b + 5b - {2a + b + [ a - 3b - 2b + a + 5b] - a}= - 3a + 3b + 5b - {2a + b + a - 3b - 2b + a + 5b - a}= - 3a + 3b + 5b -2a - b - a + 3b + 2b - a -5b + aAhora, el siguiente paso es la reorganización;
= - 3a - 2a - a - a + a + 3b + 5b - b + 3b + 2b - 5b= - 6a - 7b
Por factorización;
= - (6a + 7b)
Por tanto, podemos concluir que la simplificación de la expresión anterior es - (6a + 7b).

{2x + 3y = 10 -6x + y = 20 si se resuelve por el metodo de igualación ¿ cual es la igualdad que resulta si se despeja la variable y de ambas ecuaciones?
Answer:
Step-by-step explanation:
So im gonna be using the substitution method because its easier
We divide the equations into two and solve for y
-6x+y=20
We add 6x to both sides
-6x+y+6x=20+6x
y=6x+20
Now we plug in 6x+20 for y into the other equation
2x+3y=10
2x+3(6x+20)=10 We can simplify now
20x+60=10
20x=-50
take 20 from both sides so its gonna be a fraction
-5/2
We plug in -5/2 for x
y=6(-5/2)+20
y=5
]so therefore x is -5/2 and y is 5

The equality of the expression after removing y by substituting y is 2x + 21 = 10 - 6x + 7 = 20.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
In another word, the equation must be constrained with some constraints.
Given the expression,
2x + 3y = 10 -6x + y = 20
So,
2x + 3y = 20 and 10 - 6x + y = 20
To remove y we need to find y and substitute.
So by substituting,
10 - 6(20 - 3y)/2 + y = 20
y = 7
So,
2x + 21 = 10 - 6x + 7 = 20
Hence "The equality of the expression after removing y by substituting y is 2x + 21 = 10 - 6x + 7 = 20".

Which of the following describes the image of a triangle after a dilation that has a scale factor of 2/3?
A.-Each angle has 2/3 of the measure of its corresponding angle in the pre-image
B.-Each side has the same measure as its corresponding angle in the pre-image.
C.-Each angle has the same measure as its corresponding angle in the pre-image.
D.-Each side has 3/2 the length of its corresponding length in the pre-image.
We want to see which statement describes the image of a triangle after a dilation of scale factor of 2/3.
We will see that the correct option is C:
"Each angle has the same measure as its corresponding angle in the pre-image."
First, if we have a given figure and we apply a dilation of scale factor K, then all the measures of the given figures are affected by that dilation.
So if the 3 sides of the original triangle measured A, B, and C.
The new measures will be:
C' = k*CB' = k*BA' = k*ANotice that because all the sides changed proportionally, then the internal angles produced did not change after the dilation.
From this, we can conclude that the only correct option is C:
"Each angle has the same measure as its corresponding angle in the pre-image."
This says that the angles of the dilated triangle are the same ones as the angles of the initial triangle, which is true.

Answer:
m=11, x=6, h=5 2/3
Step-by-step explanation:
8(m-5) = 48
m-5 = 48/8 = 6
m = 6+5 = 11
m = 11
x + 7 = 13
x = 13-7 = 6
x = 6
3h - 5 = 12
3h = 12 + 5 = 17
h = 17/3 = 5 2/3 or 5.67
The manager of the commercial mortgage department of a large bank has collected data during the past two years concerning the number of commercial mortgages approved per week. The results from these two years (104 weeks) are shown to the right.
The expected number of mortgages approved per week and the standard deviation of the distribution are 2.019 and 0.024 respectively.
The expected number of mortgages approved per week :
Mean = (Σfx ÷ Σf)Expected Number approved = 210 ÷ 104 = 2.019
Hence, it is expected that 2.019 mortageahes would be approved per week.
The standard deviation :
Variance = [Σ(Xi - x)² ÷ Σf] Standard deviation = √VarianceVariance = (59.5414 ÷ 104) = 0.0005698
Standard deviation = √0.0005698
Standard deviation = 0.024
Therefore, the expected value and standard deviation are 2.019 and 0.024 respectively.

a teacher is making bags of different colors of modeling clay. the table shows the amount of each color she has avalible. each color will be divided into 3/16 pound bags. how many more bags of purple can she make then yellow?
Using the subtraction operation, the number of purple bags is 3 more than the number of yellow bags.
Amount of each color available :
Amount of purple color = 64 Amount of Yellow bags = 48Amount of color in pound required per bag = [tex]\frac{3}{16} [/tex]Number of Purple bags :
Amount of color required per bag × Amount of purple color
Number of purple bags = [tex]\frac{3}{16} \times 64 = 12[/tex]
Number of Yellow bags :
Amount of color required per bag × Amount of Yellow color
Number of yellow bags = [tex]\frac{3}{16} \times 48 = 9[/tex]
Now we find the difference between the number of Purple and Yellow bags :
Number of purple bags - Number of yellow bags
Difference = 12 - 9 = 3 bags
Therefore, there are 3 more purple bags than Yellow bags.
