(4x - 20) I really need help on this
Answer:
-80
Step-by-step explanation:
To find x, set the equation equal to zero
4x-20=0
the next step is to isolate the variable, you can do this by adding 20 to both sides, remember when you change one side of the equal sign you must do the same to both
4x=20
now you can divide by 4 to get x by itself, again divide both sides of the equation
4x/4=20/4
x=5
After doing the division we see that x is equal to 5, and you can always check to see if your answer is correct by plugging it back into the equation:
4(5)-20=0
20-20=0
Hope this helps :)

How many teams of at least 5 students and at most 7 students can be chosen from 15 students?
5 Students = 3 Teams
7 Students = 2 Teams
To find out the answer we can use the following equation
[tex]\frac{Total}{Students} \\\\\frac{15}{5} = 3 \\\frac{15}{7} = 2.14... \\[/tex]
If you run into a decimal number, like we did when we had a team of 7, you can just round down!
Answer:
3
Step-by-step explanation:
least students= 5
maximum students = 7
total number of students = 15
no: of grps if 5 students per grp = 15/5 = 3
no: of grps if 7 students per grp = 15/7 = 2.14 ~ 2
However, if they ask us how many teams in final we can say 3 as it is the maximum number of groups that can be formed b a grp of 15 students ... if we make 7 students per grp... one would be left out .
Plsssss help me with this angle circle problem what is x
Answer:
x = 3
Step-by-step explanation:
Once again we want to use the relationship stated earlier
Where A * B = C * D
Once again imagine that the segments in the given problem have letters
A = x
B = 12
C = x + 1
D = 9
Now we create an equation using the relationship
12 * x = 9(x+1)
now we solve using basic algebra
step 1 distribute the 9 to the x and the 1
9 * x = 9x
9 * 1 = 9
now we have 12x = 9x + 9
step 2 subtract 9x from each side
12x - 9x = 3x
9x - 9x cancels out
now we have 3x = 9
step 3 divide each side by 3
3x/3=x
9/3=3
we're left with x = 3
Answer:
x = 3 / C. 3

What is the length of PQ to the nearest hundreth place.(use 3.14 for *)
P
135° Q
A
12 in.
a
169.6 in.
56.5 in.
Ob
Ос
84.8 in.
Od
28.3 in.
Given:
The radius of the circle = 12 in.
The central angle of the intercepted arc PQ = 135 degrees.
To find:
The measure of arc PQ.
Solution:
The length of arc is:
[tex]s=2\pi r\times \dfrac{\theta}{360^\circ}[/tex]
Where, r is the radius and [tex]\theta [/tex] is the central angle.
Substituting [tex]r=12,\pi=3.14,\theta=135^\circ[/tex] in the above formula, we get
[tex]s=2(3.14)(12)\times \dfrac{135^\circ}{360^\circ}[/tex]
[tex]s=75.36\times 0.375[/tex]
[tex]s=28.26[/tex]
[tex]s\approx 28.3[/tex]
The measure of arc PQ is 28.3 in. Therefore, the correct option is (d).
It costs $90 720 to stay in a
hotel for 7 days. How much does it
cost to stay for 3 days?
Answer:
$38 880
Step-by-step explanation:
So for 7 days it costs $90 720
First we need to find what 1 day cost
So you will divide $90 720 by 7
90 720÷7= $12 960
To find the cost for 3 days your gonna multiply $12 960 by 3
12 960×3= $38 880

Sylvia made 32 of her 50 free throws at basketball practice.
What percent of her free throws did she miss?
Answer: 36%
Step-by-step explanation: A simple way to figure out is to do 32/50 times 2. This makes it 64/100. 100 minus 64 is 36 which is the percent on how much free throws she mised
Find XS, VY, and YZ. I am very confused on what to do.
Answer:
Do you see the lines and how they are named? I am going to try and explain this in less words than I can. Where it says XS you have to match it up with the lines. But if it says that you have to find XSU (which it does not) you would have to go up all the way but you stop where it says the S so you wont go all the way up to the U. I hope this helps!
your backyard is shaped like a rectangle and measure's 45 1/2 feet by 50 feet. you want to put a fence around your backyard. how much fence will you need?
Answer:
191 ft
Step-by-step explanation:
If it's 45.5ft x 50ft, we'll need to put fence around two 45.5ft sides and two 50ft sides.
2*45.5ft + 2*50ft = 91ft + 100ft = 191ft

n+37=180
n=180-37=143°
Answer:
B) 143°
Step-by-step explanation:
Since n° is supplementary to 180°, then n°=180°-37°=143°.
Find the measure of minor arc QN.
M
0
K
IN
38
Р
Answer:
142°
Step-by-step explanation:
Minor arc QN = m(MN) + m(QM)
n(MN) = m<MKN = 90° (central angle = measure of intercepted arc)
m(NO) = m<NKO = 38° (measure of intercepted arcs)
m(QM) = 180° - (m(MN) + m(NO)) (half circle)
Substitute
m(QM) = 180° - (90° + 38°)
m(QM) = 52°
✔️Minor arc QN = m(MN) + m(QM)
Substitute
Minor arc QN = 90° + 52° = 142°
This recipe makes 6 portions of chocolate mousse.
Cali has 600 g chocolate, 36 eggs, 100 mL of lemon juice and 200 g of sugar.
Cali makes 12 portions of mousse by following this recipe.
How much of each ingredient will she have left?
Recipe: Serves 6
180 g chocolate
9 eggs
15 mL lemon juice
60 g sugar
Answer:
240 g chocolate
18 eggs
70 mL lemon juice
80 g sugar
Step-by-step explanation:
600 g choc - (2 x 180) = 240 g left
36 eggs - (2 x 9) = 18 left
100 mL lemon - (2 x 15) = 70 mL left
200 g sugar - (2 x 60) = 80 g left
Answer:
Ingredients will have left
Chocolate
600 - 2*180 = 240 gEggs
36 - 2*9 = 18Lemon juice
100 - 2*15 = 70 mlSugar
