Find the value of x : x/15 = 8/20
Answer:
x=6
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
x/15=8/20
Multiply both sides by 10:
x/15*10=8/20*10
Simplify:8/20*10
2x/3=4
Multiply both sides by 3:
3*2x/3=4*3
simplify:
2x=12
Divide both sides by 2:
2x/2=12/2
Simplify:
x=6

what is the solution set of this inequality x < -10 i need help
Answer:
x= 1 (any number greater than -10)
Step-by-step explanation:
">" this sign shows that any number greater than -10 can be x. There is no specific answer.
Answer:
The solution set of an inequality is < (less than) or > (greater than) to compare two or more numbers. Example 12 > - 10.
Step-by-step explanation:
When comparing two numbers, like 5 and 8, you probably recognize that the number 5 is less than the number 8. You probably also realize that the number 8 is greater than the number 5. In math, we use the inequality symbols < and > to compare two or more numbers.
can someone help me with this please, i am not sure what to do
Answer:
I attached the graph below
Step-by-step explanation:
I started at the y-intercept, because it is where the line crosses the y-axis. Then, I used rise/run for the slope (-5/3) and went down 5 units and right 3 units. I connected the points to make the graph.

The sum of two numbers is 46 and their
difference is 20. What is the smaller
number?
1
A) 40
B) 13
C) 26
D) 12
Answer:
B. 13
Step-by-step explanation:
We have two unknown numbers, let's have two variables for these two unknown numbers, X and Y.
"The sum of two numbers is 46 and their difference is 20."
Meaning we have two equations :
X + Y = 46
X - Y = 20
Looking at the last part of "their difference is 20." We can assume X = Y + 20
So substitute the assumed equation into X + Y = 46
(Y + 20) + Y = 46
2y + 20 = 46
Subtract 20 from both sides :
2y = 26
Divide 2 by both sides :
y = 13
There you go.
Andre is making paper cranes to decorate for a party. He plans to make one large paper
crane for a centerpiece and several smaller paper cranes to put around the table. It takes
Andre 10 minutes to make the centerpiece and 3 minutes to make each small crane. He will
only have 30 minutes to make the paper cranes once he gets home.
1. Andre wrote the inequality 3x + 10 < 30 to plan his time. Describe what x, 3x, 10,
and 30 represent in this inequality.
Answer:
x is the number of small cranes he can make
3x is the amount of time it takes to make all of those small cranes
10 is the amount of time it takes to make just the centerpiece
30 is how much time in total he has to make all of the paper cranes
Step-by-step explanation:

s=2πcx+3πc^2 solve for x
Answer:
x = (s - 3πc^2) / 2πc.
Step-by-step explanation:
s = 2πcx + 3πc^2
2πcx = s - 3πc^2
x = (s - 3πc^2) / 2πc.
Maya has 54 cubic feet in her garden she already has 4.5 cublc feet of soil .Soil bags have 1.5 how many bags should maya purchace.
Answer: 33
Step-by-step explanation:
The cubic feet needed is 54 and she already has 4.5 cubic feet of soil. This mean that she will need 49.5 more.
= 54 - 4.5
= 49.5
Since each soil bag has 1.5, the number of soil bags needed will be:
= 49.5 / 1.5.
= 33
Therefore, she'll need 33 bags

On three days, Ben throws darts at a target.
Here are his results.
Number of throws
Number of hits
Number of misses
40

30
18
Monday
Tuesday
Wednesday
Total
12
50
36
14
120
84
36
b) Use the total of the results to estimate the
probability of Ben of hitting the target.
Answer:
[tex]P(Hits) = 0.70[/tex]
Step-by-step explanation:
Given
[tex]Throws = 120[/tex]
[tex]Hits = 84[/tex]
[tex]Miss = 36[/tex]
See attachment for result
Required
Determine the probability of hitting the target
This calculated using:
[tex]P(Hits) = \frac{n(Hits)}{n(Throws)}\\[/tex]
[tex]P(Hits) = \frac{84}{120}[/tex]
[tex]P(Hits) = 0.70[/tex]
Hence, the probability of hitting the target is 0.70
At a dance, 25% dresses up in a superhero costume, 32% as a scary character, 10% as an entertainer, 15% as a children's movie character, and 16% did not dress up at all. If a total of 250 students attended the dance and 15% of the scary character students were girls, how many boys dressed up as a scary character?
Answer:
68 boys
Step-by-step explanation:
32% of 250 = 80
of 80 scary characters, 15% were girls
80 x .15 = 12 (girls)
80 - 12 = 68 (boys)
