Step-by-step explanation:
an electronics warehouse ships televisions and DVD players in certain combinations to retailers throughout the country. The weight of 4 Televisions and 6 DVD players is 70 pounds, and the weight of 2 televisions and 5 DVD players is 37 pounds. Let represent the amount of pounds per TV and represent the amount of pounds per DVD. How much did each television and DVD player weigh?
Answer:
d = 1
t = 16
Step-by-step explanation:
Television = t
DVD = d
4t + 6d = 70
2t + 5d = 37
2t + 5d = 37
2t = 37 - 5d
2t/2 = 37/2 - 5d/2
t = 18.5 - 5/2d
4t + 6d = 70
4(18.5 - 5/2d) + 6d = 70
74 - 10d + 6d = 70
-4d = -74 + 70
-4d = -4
-4d/-4 = -4/-4
d = 1
2t + 5d = 37
2t + 5(1) = 37
2t + 5 = 37
2t = 37 - 5
2t = 32
2t/2 = 32/2
t = 16
Check: d = 1; t = 16
4t + 6d = 70
4(16) + 6(1) = 70
64 + 6 = 70
70 = 70
2t + 5d = 37
2(16) + 5(1) = 37
32 + 5 = 37
37 = 37

Answer/Step-by-step explanation:
✔️m<1 + 52° = 180° (consecutive angles angle)
m<1 = 180 - 52
m<1 = 128°
✔️m<2 = 52° (alternate interior angles are congruent)
✔️m<3 = 47° (alternate interior angles are always equal)
✔️m<4 + 47° = 180° (consecutive angles)
m<7 = 180 - 47
m<7 = 133°
✔️m<5 = 180 - (52 + 47)
m<5 = 180 - 99
m<5 = 81°

Teal Street is the line 2x - 3y = 9 Write out this equation as y = mx + b
Answer:
[tex]y = \frac{2}{3} x - 3[/tex]
Step-by-step explanation:
For the equation to be written in the form of y=mx+b, ensure that the y term is on one side of the equation and bring the rest to the other side. Then divide the whole equation by the coefficient of y, so that the resulting coefficient of y is 1.
2x -3y= 9
-3y= -2x +9 (-2x on both sides)
Dividing both sides by -3:
[tex]y = \frac{2}{3} x - 3[/tex]

A right triangle has vertices at (0,9), (4,9) and (4, 4). What is the equation of the line that includes the hypotenuse? y =
Answer:
y = - 1.25x + 9
Step-by-step explanation:
A(0,9) B(4,9) C(4,4)
AB² = (4-0)² + (9-9)² = 16
AC² = (4-0)² + (4-9)² = 41
BC² = (4-4)² + (4-9)² = 25
AC is hypotenuse with y interception of 9
slope = 5/4 = -1.25
equation: y = - 1.25x + 9
If a circle has a radius of 8 cm, what is its diameter?
a.
8 cm
c.
4 cm
b.
16 cm
d.
½ cm
Answer:
A = 16cm
B = 32cm
C = 8cm
D = Sorry the time I learned this I didn't learn it for fractions.
There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pie you can calculate the circumference.
The diameter is the distance from one side of the circle to the other at its widest points. The diameter will always pass through the center of the circle. The radius is half of this distance.
The formula for working out the circumference of a circle is:
Circumference of circle = π x Diameter of circle
This is typically written as C = πd.

All the angles make a full circle which needs to equal 360 degrees.
Add all the angles together to equal 360:
X + (x-10) + (4x-20) +(2x-10) + (x +10) = 360
Combine like terms:
9x -30 = 360
Add 30 to both sides:
9x = 390
Divide both sides by 9:
X = 390/9
X = 43.3333. ( 43 and 1/3)
Answer:
x = 43 1/3 degrees.
Step-by-step explanation:
All these angles add up to 360 degrees , so we have:
x - 10 + 4x - 20 + 2x - 10 + x + 10 + x = 360
9x - 30 = 360
9x = 390
x = 390/9
= 43 1/3 degrees
DE is a Mid-segment of triangle ABC. How long is DE?
Answer:
DE = 14
Step-by-step explanation:
Since, DE is a Mid-segment of triangle ABC.
Therefore,
DE = 1/2 * AC
2 DE = AC
2(5x - 1) = 3x + 19
10x - 2 = 3x + 19
10x - 3x = 19 +2
7x = 21
x = 21/7
x = 3
DE = 5x - 1
DE = 5*3 - 1
DE = 15 - 1
DE = 14
In a standard deck of cards, what is the probability of drawing a face card?
Answer (round) to the hundredth place value.
Reasoning:
There are 12 face cards since there are 3 face cards in any suit, and 4 suits. So 3*4 = 12.
There are 52 cards total.
Dividing the values leads to 12/52 = 0.230769 which rounds to 0.23
An 8-ounce cup of gourmet coffee costs $4.50.If the price remains the same how much would 3 quarts cost
Answer:
$54
Step-by-step explanation:
1 quart = 32 fl oz
3 quarts would contain 32 x 3 = 96 quarts
1 ounce would cost : $4.50 / 8 = $0.5625
96 quarts would cost = 96 x $0.5625 = $54

What is a quadratic equation? And how do you solve them?
Answer:
A quadratic equation is some thing like
(x+2)^2
or
(x+2)(x+5)
In order to solve them, the most basic method is the FOIL method
F-First
O-Outside
I-Inner
L-Last
So for example
(x+2)^2
Which is basically
(x+2)(x+2)
So the first is the 2 Xs
(x+2)(x+2)
x*x=x^2
The outer is the x and the 2,
(x+2)(x+2)
2*x=2x
Now the Inner which is the 2 and the x
(x+2)(x+2)
2*x=2x
And finally the last which is the 2 and the second 2
(x+2)(x+2)
2*2=4
Now add them all up
X^2+2x+2x+4
Combine like terms
x^2+4x+4
There you have it

Which graph represents the proportional relationship given by the rule "y is 3 times the value of x"?
Please answer fast less than 5 min
Answer:
The fourth graph i.e. RIGHT BOTTOM GRAPH is correct which represents the proportional relationship given by the rule y = 3x.
Also, the correct graph is attached below.
Step-by-step explanation:
Given the rule
''y is 3 times the value of x".
It means
y = 3x
comparing with the slope-intercept form of the line equation
y = mx+b
where y is the slope and b is the intercept
so,
The slope of y = 3x will be: m = 3
The y-intercept of y = 3x will be: b = 0
CHECKING THE 4TH GRAPH (THE RIGHT BOTTOM SIDE)
Taking two points
(0, 0)
(2, 6)
Finding the slope between (0, 0) and (2, 6)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [6 - 0] / [2 - 0]
= 6 / 2
= 3
Thus, the slope of the line = m = 3
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 0
Thus, the y-intercept b = 0
Now, substituting m = 3 and b = 0 in the slope-intercept form of linear function
y = mx+b
y = 3x+0
y = 3x
Therefore, the fourth graph i.e. RIGHT BOTTOM GRAPH is correct which represents the proportional relationship given by the rule y = 3x.
Also, the correct graph is attached below.
Answer:
It's the bottom right graph.
Step-by-step explanation:
