Answer:
Step-by-step explanation:
The two angles would equal 180°.
(7x - 5) + (5x + 19) = 180
Combine like terms.
12x + 14 = 180
Simplify by isolating the variable
12x + 14 = 180
------ -14 ----------
12x = 166
Divide both sides by 12
x = 13.833

An airplane is flying from New York City to Los Angeles. The distance it travels in miles, d, is related to the time in seconds, t, by the equation d=0.15. How fast is it flying? Do not include units
Answers
Answer:
0.15
Step-by-step explanation:
Given the expression that relates the distance and the time with the expression:
d = 0.15t
d is the distance
t is the time
To determine how fast it is flying (Speed), we will need to use the formula
Speed = distance/time
s = d/t
From the given equation we can se that 0.15 = d/t
Comparing this to the general equation, we will see that s = 0.15
Hence the airplane is flying at 0.15

Howie works at a petting zoo. He fed a piglet 1/5 of a bottle of milk then gave 3/4 of what was left to the calf. How much of the bottle of milk did the calf drink
Answers
Answer:
[tex]\frac{3}{5}[/tex]th part of the bottle will be drunk by the calf.
Step-by-step explanation:
Part of the bottle fed by the piglet = [tex]\frac{1}{5}[/tex]
Milk left in the bottle = 1 - [tex]\frac{1}{5}[/tex]
= [tex]\frac{5-1}{5}[/tex]
= [tex]\frac{4}{5}[/tex]
Milk drunk by the calf = [tex]\frac{3}{4}[/tex]th of the left part
= [tex]\frac{3}{4}\times \frac{4}{5}[/tex]
= [tex]\frac{3}{5}[/tex]th part of the bottle
Therefore, [tex]\frac{3}{5}[/tex]th part of the bottle will be drunk by the calf.

Answer:
35° (Verified Answer) ✅Step-by-step explanation:
Well, we know that all three angles of a triangle add up to 180°, we set the three equations added together equal to 180°.
180 = x + 10 + 3x - 5 + x
We can simplify this to:
180 = 5x + 5
Now, all we need to do is solve.
Subtract 5.
175 = 5x
Divide by 5
x = 35°
Now, we must check this solution by substituting our solution for x in for x, to see if the values equal.
180 = 35 + 10 + 3 (35) - 5 + 35
180 = 45 + 3 (35) - 5 + 35
180 = 105 + 45 - 5 + 35
180 = 150 - 5 + 35
180 = 150 + 30
180 = 180 ✅

Together, Ashley and Gabby watched a total of 14 hours of television over the weekend. Ashley watched 6 times as many hours as Gabby. How many hours of television did they each watch over the weekend? Write and solve a system of equations by using the substitution method. Be sure to define your variables.
Answers
Answer:
The number of times over the Weekend that:
Ashley watched TV = x = 12 hours
Gabby watched TV = y = 6 hours
Step-by-step explanation:
Let us represent:
The number of times
Ashley watched TV = x
Gabby watched TV = y
Together, Ashley and Gabby watched a total of 14 hours of television over the weekend.
= x + y = 14..... Equation 1
x = 14 - y
Ashley watched 6 times as many hours as Gabby.
x = 6y
Using substitution method
We substitute 14 - y for x
14 - y = 6y
14 = 6y + y
14 = 7y
y = 14/7
y = 2 hours
Solving for x
x = 14 - y
x = 14 - 2
x = 12 hours
Therefore:
The number of times over the Weekend that:
Ashley watched TV = x = 12 hours
Gabby watched TV = y = 6 hours

Step-by-step explanation:
We have the equation: x+y=6
We want to get this in the form: y=mx+b (or in this case y=x+b)
To do this we need y to be positive and by itself
So we subtract y from both sides and divide by -1 (we divide by -1 because otherwise y would be negative and that does not fit our template of y=x+b)
Doing this we have
-x+6=y
From here we just plug in numbers -2 to 3 which I will assume you know how to do

Write the equation of the line that passes through the points (-8,3) and
(3,2). Put your answer in fully reduced point-slope form, unless it is a
vertical or horizontal line.
Answers
Answer:
Slope of a line can be found by
y~2 - y~1 / x~2 - x~1
The coordinates given are (-8,3) and (3,2)
2 - 3 / 3 - (-8) = - 1/11 this is your Slope, m
Use the Slope and either point to find b by substituting x and y and m values we know into
y=mx+b
2 = -1/11(3) + b simplify
2 = - 3/11 + b isolate b by adding 3/11 to both sides
22/11 + 3/11 = b = 25/11
Use m and b to write your equation.
y= - 1/11x + 25/11
A sporting goods store brought in some new mountain bikes that cost $1,200 each and kayaks that cost $800 each. A total of 32 of these items were acquired , for $30,400 . How many new mountain bikes did the store bring in ? ASAP HELP!

Han earns $33.00 for babysitting 4 hours. At this rate, how much will he earn if he
babysits for 7 hours. You may solve with any method but you must show your work.
Answers
Step-by-step explanation:
First, you want to find the unit rate, or how much Han earns per hour
You can do this by setting up an equation
x= amount earned per hour
4x= 33 Initial equation
4x/4 = 33/4 Isolating the variable
x = 33/4 = 8 1/4 = 8.25 The unit rate
Now you want to set up a new equation to find out how much he makes for 7 hours
x= amount earned per hour
y = total amount earned
y = 7x Initial equation
y = 7 ( 8.25) Substitution
y = 57.75 The answer
Han earns $57.75 for every 7 hours
Checking the answer....
y = 7x
57.75 = 7x Substitute y instead
57.75/7 = 7x/7
8.25 = x
Your answer should be correct

What is the length of DE in the image provided? (Please explain so I can understand in the future)
A. DE=4
B. DE=5
C. DE=6
D. DE=7
Answers
==========================================================
Explanation:
We have these three facts:
The arc markings on angles C and D indicate those angles are congruent. We can say that angle ACB = angle EDB.Another pair of congruent angles are angle ABC and angle EBD. These are vertical angles. Lastly, we have a pair of congruent sides AB and BE because of the tickmarks.Those three facts allow us to use the AAS (angle angle side) congruence theorem to prove that triangle ABC is congruent to triangle EBD.
Then by CPCTC (corresponding parts of congruent triangles are congruent), we know that AC = DE. Note how 'A' and 'C' are the first and last letters of ABC; similarly, 'E' and 'D' are the first and last letters of EBD. Segment ED is the same as segment DE.
So to find the length of DE, we need to find the length of AC. To do that, we need the value of x.
----------------
Recall earlier that AB = BE. Use this to find x
AB = BE
1.5x = 3x-6
1.5x-3x = -6
-1.5x = -6
x = -6/(-1.5)
x = 4
Now we can find the length of AC
AC = x+3
AC = 4+3
AC = 7
This must mean DE = 7 as well.
Answer:
DE=7

Mr. Harris has batteries for his calculators. If b represents the number of batteries and c represents his calculators, how many
batteries does Mr. Harris have?
b= 4c
3c = -2b + 44
A 4 batteries
B 7 batteries
13 batteries
16 batteries
Answers
b = 4c
3c = -2b + 44
3c = -2(4c) + 44
3c = (-2 x 4c) + 44
3c = -8c + 44
11c = 44
c = 44/11
c = 4
b = 4c
b = 4(4)
b = 4 x 4
b = 16
Therefore, Mr. Harris has 16 batteries.
