Answer:
Here's how to solve it.
Step-by-step explanation:
Okay,
from what I understand she has 20 train cars total.
She uses 5 for each train.
So to solve you use simple division.
20 / 5 = 4
To check your answer substitute 4 in the equation so 4 × 5 does equal 20.
So it would be 4.

Answer:
<ABD = 44
<DBC = 44
<ABC = 88
Step-by-step explanation:
If an angle bisects another, then the two resulting angles are equal
In this case <ABC is bisected by BD
which means that
<ABD = <DBC
so
6x + 14 = 3x + 29
simplify and solve using inverse operations
6x + 14 = 3x + 29
-3x -14 -3x -14
3x = 15
/3 /3
x = 5
now substitute into the given values
< ABD = 6x + 14
= 5 * 6 + 14
= 30 + 14
= 44
<DBC = 3x + 29
= 5 * 3 + 29
= 15 + 29
= 44
< ABC = <ABD + <DBC
<ABC = 44 + 44
= 88

Two supplementary angles are in the ratio 2:7. Find the measure of the Acute angle.
Answer:
y=42.3333333333 (repeating)
Step-by-step explanation:
You need to find the corresponding side. You can see D H is corresponding to E C. So here is what you have to do, find x to (8x - 43) and (2x + 13).
2x + 13 + 8x - 43= 90
10x -30 = 90
+30 +30
10x = 120
/10 /10 = 12
to check if this is right take x which is 12 and plug it in.
8 x 12= 96 then 96 - 43= 53
2 x 21= 24 then 24 + 13= 37
Next you take 53 and 37 and add it together
53 + 37= 90
about that corresponding side, now you know D H and E C both equal 53
Now you can solve your equation.
53 + 2y + y= 180
53 + 3y = 180
-53 -53
3y = 127
/3 /3
y = 42.333333 (repeating)
to check if this is right take y which is 42.3333333 (repeating) and plug it in.
2y means to multiply y two times so...
42.3333333 (repeating)+ 42.33333333 (repeating)= 84.6666666 (repeating)
y = 42.333333333 (repeating)
E C = 53
add all the numbers together
42.333333 (repeating) + 84.66666666 (repating)+ 53= 180
Therefore y equals 42.33333333 (repeating)

In order to evaluate energy demand for heating services, the number of heating degree days are calculated. The number of heating degree days can be calculated by the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day. If the high temperature for a day was 51°F and the low temperature for the same day was 45°F, what is the number of heating degree days? A. 17 B. 48 C. 113 D. 14
Given that,
The number of heating degree days can be calculated by the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day.
Solution,
The high temperature was 51°F and the low temperature was 45°F.
Average of high and low temperatures for the day is given by :
[tex]T=\dfrac{51+45}{2}\\\\T=48^{\circ} F[/tex]
Now using formula :
H = 65 - T
H = 65 - 48
H = 17
Hence, there are 17 heating degree days.
Simplify.
Rewrite the expression in the form.

Find the slopes of the linear functions.
y = -2x + 7
The slope of the line given by the linear equation is
-2v.
The slope of the line shown in the graph is V-14
Answer:
Find the slopes of the linear functions.
On a coordinate plane, a line goes through points (0, 6) and (6, 0). Y = negative 2 x + 7.
The slope of the line given by the linear equation is
✔ -2
.
The slope of the line shown in the graph is
✔ -1
.
Step-by-step explanation:
on edge 2020
The slope of linear Equation is -2.
what is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
y= -2x+ 7
Now, we know the standard form of slope- intercept form
y= mx+ b
where m is slope and b is the y- intercept
Now, Comparing it with given equation we get
slope, m= -2

Solve the equation x^2 = 10.
Answer: [tex]\sqrt{10\\[/tex]
Step-by-step explanation:
To solve for x you would have to take the square root of both side.
Answer:

what is an equation that passes through -1,2 and is parallel to the point 3x+y=3 ?
Answer:
y=3x+5
Step-by-step explanation:
For this you can use the point-slope formula: y-y1=m(x-x1). Since the line we're looking for is parallel, both slopes are equivalent.
First, you have to rewrite the primary equation into standard form, which would rewrite to y=3-3x or y=-3x+3. Then, you can use the information we have in the point-slope formula:
y-(2)=3(x+1)
y-2=3x+3
y=3x+5
Check:
(2)=3(-1)+5
2=-3+5
2=2

For which value of x is the function 2x^2 + 3x + 1/x - 1 g(x) undefined?

We have
