Answer:
x=1/15 y = -4 1/3
Step-by-step explanation:
First combine like terms.
-3y = 13
y= -13/3
y= -4 1/3
Substitute for y in next equation
-4 1/3 = 5x - 4
5x = 4 1/3 - 4
5x = 4 1/3 - 4
5x = 1/3
x = 1/3 divided by 5
Since fractions can't be divided, multiply by the inverse
x = 1/3 times 1/5 = 1/15

g/h-x=Q
solve for g
Answer:
g=(q+x)/(h)
Step-by-step explanation:
you would 1st add x to the q
g/h=q+x
then you would divide the h from both sides
g=(q+x)/(h)

ana buys a sweater for $25.60, and it is on sale for 35% off. what is the amount of the discount?
Answer:
16.64
Step-by-step explanation:
First times 25.60 by 35
Which is 896 then divide by 100
You should get 8.96
And then subtract it from 25.60
You get 16.64
therefore 25.60, 35% off is 16.64

Freddy tiene $250 en billetes de diez dólares. ¿Cuántos billetes de diez dólares tiene Freddy? Le dio 6 billetes de diez dólares a su hermano. ¿Cuántos billetes de diez dólares le quedan?
Answer:
-Freddy tiene 25 billetes de diez dólares.
-A Freddy le quedan 19 billetes de diez dólares.
Step-by-step explanation:
Para encontrar la cantidad de billetes de diez dólares que tiene Freddy, tienes que dividir la cantidad total que tiene entre diez:
250/10=25
Esto significa que Freddy tiene 25 billetes de diez dólares.
Para saber cuantos billetes le quedan a Freddy, tienes que restar los 6 billetes que le dio a su hermano del total de billetes que tenía:
25-6=19
De acuerdo a esto, a Freddy le quedan 19 billetes de diez dólares.

Answer:
x = 4[tex]\frac{1}{2}[/tex] teaspoons of baking powder
Step-by-step explanation:
I will use ratio, so for every 10 muffins we need 1[tex]\frac{1}{4}[/tex] or [tex]\frac{5}{4}[/tex] teaspoons of baking powder. How much would we need for 3 dozens or 36 muffins?
Set up the ratio in fractions
[tex]\frac{10}{\frac{5}{4}}[/tex] = [tex]\frac{36}{x}[/tex]; where x is the teaspoons of baking powder
solve for x
x =(36*[tex]\frac{5}{4}[/tex]) / 10
x = (45)/10 = 4[tex]\frac{5}{10}[/tex] = 4[tex]\frac{1}{2}[/tex] teaspoons of baking powder
Select all the zeros of the function f(x) = (x + 10)(x - 5)(x + 1).

What is the equation of the line that passes through the point (2,0) and has a slope of 5/2 ?
Answer:
y = [tex]\frac{5}{2}[/tex] x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{5}{2}[/tex] , thus
y = [tex]\frac{5}{2}[/tex] x + c ← is the partial equation
To find c substitute (2, 0) into the partial equation
0 = 5 + c ⇒ c = 0 - 5
y = [tex]\frac{5}{2}[/tex] x - 5 ← equation of line
The equation of the line is the way of represent the line by the given point in the coordinate plane and the its slope.. Thus the equation of the line with point (2,0) and slope 5/2 is,
[tex]y=\dfrac{5}{2} x-2[/tex]
Given information;
The point of the line through which the line passes are (2,0).
The slope of the line is 5/2.
Equation of the lineThe equation of the line is the way of represent the line by the given point in the coordinate plane and the its slope.
The standard form of the equation of the line for point and slope can be given as,
[tex](y-y_1)=m(x-x_1)[/tex]
Put the values,
[tex](y-0)=\dfrac{5}{2} (x-2)[/tex]
Solve it further;
[tex]y=\dfrac{5}{2} x-2[/tex]
Thus the equation of the line with point (2,0) and slope 5/2 is,
[tex]y=\dfrac{5}{2} x-2[/tex]

Hello everyone I need help with this worksheet it's ten problems answer the ones you know for me please it's homework.
I need help with finding the of two points.
1. (1,10) and (11,2)
2. (4,6,) and (-11, -4)
3. (-8, -6) and (-5, -6)
4. (-2, -7) and (10, -16)

8. (-5, 14) and (-3,11)
9. (-18, 16) and (2, -9)
10. ( 4, 6) and (1,2)
Answer:
1. Slope = -4/5
2. Slope = 2/3
3. Slope = 0
4. Slope = 3/-4
5. Slope = 7/-12
6. Slope = 1/2
7. Slope = -2/0 --> Undefined
8. Slope = 3/-2
9. Slope = 5/-4
10. Slope = 4/3
Step-by-step explanation:
Ok so I'm assuming that you want the slope for all the two points. Basically, the formula for slope is rise/run, or y2-y1/x2-x1. Solve using that. For example, for number 1, it would be:
10-2/1-11 = 8/-10 = -4/5

Answer:
3
Step-by-step explanation:
Answer:
g=4.33
Step-by-step explanation:
8.95 - 5.4g = 3.81 - 9.58 - 8.69
-5.4g = 3.81 -9.58 -8.69 - 8.95
-5.4g = 5.77 - 8.69 - 8.95
-5.4g = -14.46 - 8.95
-5.4g = 23.41
-5.4/-5.4 =23.41/-5.4

Mr. Diaz bought a board that was 7 feet long. He cut the entire board into pieces that were LaTeX: \frac{1}{3}1 3 foot long. How many pieces did Mr. Diaz have ?
Answer: Mr. Diaz will have 21 pieces.
Step-by-step explanation:
Given, Length of the complete piece bought by Mr. Diaz= 7 feet
Length of each piece cut = [tex]\dfrac13[/tex] foot
By division operation,
Number of pieces = ( Length of complete piece ) ÷ (Length of each piece cut)
[tex]=7\div\dfrac13=7\times3=21\ \ [\because a\div \dfrac{b}{c}=a\times\dfrac{c}{b}][/tex]
Hence, Mr. Diaz will have 21 pieces.
