Answer:
x = −2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(4x+6)=x−4
(3)(4x)+(3)(6)=x+−4(Distribute)
12x+18=x+−4
12x+18=x−4
Step 2: Subtract x from both sides.
12x+18−x=x−4−x
11x+18=−4
Step 3: Subtract 18 from both sides.
11x+18−18=−4−18
11x=−22
Step 4: Divide both sides by 11.
[tex]\frac{11x}{11}[/tex] = [tex]\frac{-22}{11}[/tex]
x = −2

Rachel is a stunt driver, and she's escaping from a building that is about to explode!
The variable d models Rachel's distance from her exit (In meters) t seconds after the cameras began recording the stunt
What is Rachel's speed?
Answer:
The variable d models Rachel's distance from her exit (in meters) t seconds after the cameras began recording the stunt. d = - 38t
Step-by-step explanation:
From given, we have, The expression that represents the Rachel's distance is given by, d = - 38t + 220
where, d represents the distance in meters
t represents the time in seconds
We know that, speed = distance by time. Therefore, we need to differentiate the given equation w.r.t to time to find the speed.
we have, d/dt (d) = d/dt [- 38t + 220]
| d/dt (d) | = | - 38 + 0 |
s = d/dt (d) = 38 m/s
Therefore, the speed of Rachel is 38 m/s.
Answer:
38 meters per second

Kenny wants to learn how to serve overhand in volleyball. When he practiced yesterday, he made 7 serves over the net for every 2 serves that did not go over the net.If Kenny attempted 36 serves yesterday, how many serves did he make over the net?
Answer: 28
Step-by-step explanation:
Given
Kenny made 7 serves over the net for every 2 serves that did not go over the net i.e. success rate of Kenny is
[tex]\Rightarrow \text{success rate}=\dfrac{7}{2+7}\times 100=\dfrac{700}{9}\%[/tex]
for 36 serves, applying the same success rate, it is
[tex]\Rightarrow \text{success rate}=\dfrac{700}{9}\times\dfrac{1}{100}\times 36=28[/tex]
Serves that did not make over the net is [tex]36-28=8[/tex]
Thus, Kenny will make 28 serves that make over the net
There are 54 students on a school bus. The number of high school
students is 3 more than twice the number of middle school students.
How many of high schoolers are on the bus? State your answer in a
sentence.
Answer: there are 37 high school students on the bus
Step-by-step explanation:
h+m=54 total number of students
h= 2m+3 total number of HS students
2m+3+m=54 Substitute 2m+3 in for h
3m+3=54
3m=51
m=17
h+17=54
h= 37

Step-by-step explanation:
7(4y + 9)
7 x 4y (28y)
7 x 9 (63)
you would multiply 7 and 4y to get 28y and then multiply 7 and 9 to get 63 and you would add the plus sign to get the full answer which is 28y+63

In parallelogram ABCD, if ED = 7x - 13 and BD = 16x - 38, find BD.
Answer:
58
Step-by-step explanation:
The length of BD is 58 units.
What are properties of parallelogram?The two diagonals cut across one another. The parallelogram is divided into two congruent triangles by each diagonal. A parallelogram's total square sum and total square sum of its diagonals are equivalent. Additionally known as the parallelogram law.
Given:
ED = 7x - 13 and BD = 16x - 38
So, the Diagonals of parallelogram bisect each other
BD = ED+ EB
16x - 38 = 2 ED { ED= EB}
16x - 38 = 2 (7x- 13)
16x - 38 = 14x - 26
2x = 12
x= 6
So, length of BD = 16(6) - 38 = 96- 38 = 58 units

m=?
HELPPP
Answer:
12
Step-by-step explanation:
This is correct. Trust me.
I'm glad I could help:)
6m+27=8.25m
You have to subtract 6m on both sides first.
6m+27=8.25m
-6m -6m
27=2.25m
Now we divide 2.25 from both sides.
27=2.25m
/2.25 /2.25
12=m

A ladder is leaning against
a brick building as shown in the figure. What
is the length of the ladder?
x ft
20 ft
15 ft
Answer:
25 ft
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
15^2 + 20 ^2 = x^2
225+400= x^2
625 = x^2
Take the square root of each side
sqrt(625) = sqrt(x^2)
25 = x
