Answer:
I think the number is 10.
Step-by-step explanation:
Seven less than a number is x - 7 (If x is the number). Then x - 7 = 3 so, x = 3+7 = 10.

5. Mr. Quick bought a new computer system. The regular price was $1580, but he got a 15% discount. How much did he pay?
Answer:
He paid $1343
Step-by-step explanation:
[tex]\frac{x}{1580} =\frac{15}{100}[/tex]
Cross multiply
[tex]x100=23700[/tex]
Divide 100 from both sides
[tex]x=237[/tex]
1580 - 237 = 1343

9 ) Jason bought 9 new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are now only 31 cards left. How many cards did Jason start with ?
Answer:
He started with 53 cards
Step-by-step explanation:
He has 31 now
If 31 is half of what he had, then we need to double it
31 x 2 = 62
If he had bought 9, then we need to do the opposite
62 - 9 = 53

17 = -13 - 8x
can i get it step by step
Answer:
x = 30/-8 = -15/4 = -3.75 = -3 3/4
Step-by-step explanation:
17 = -13 - 8x
add 13 to each side
30 = -8x
divide each side by -8
30/-8 = x
30/-8 = -15/4 = -3.75 = -3 3/4
To amend the U.S. Constitution, 3/4 of the 50 states must approve the amendment. If 35 states approve the amendment will the constitution be amended
bearing in mind that fraction wise we can represent any WHOLE as 1, 5/5 = 1, or 333/333 = 1, so we can say that the whole of the states or namely 50/50 = 1, so we can say that
[tex]\begin{array}{ccll}amount&fraction\\\cline{1-2}50&1\\35&x\end{array}\implies \cfrac{50}{35}=\cfrac{1}{x}\implies 50x=30\implies x=\cfrac{30}{50}\\\\\\\boxed{x = \cfrac{3}{5}\implies 0.7}\\\\[-0.35em]~\dotfill\\\\\cfrac{3}{4}\implies 0.75~\hspace{10em}\stackrel{\textit{since 0.7 is less than 0.75, \underline{nope}}}{0.7 < 0.75}[/tex]
Every day Sasha spends 45 minutes practicing the oboe. She has already practiced the oboe for 22 minutes today. How much longer must she practice today?
How do I solve this?
Answer:
X = 10
Step-by-step explanation:
<1 = 2x + 10
<2 = x + 20
<3 = 180 - 6x (linear angles = 180 degrees)
<1 + <2 + <3 = 180 degrees
2x + 10 + x + 20 + 180 - 6x = 180
-3x + 210 = 180
-3x = 180 - 210
x = -30/-3
x = 10

Calculate the simple interest rate. (Round your answer to one decimal place.)
P = $3600, I = $330, t = 1 year
Answer:R = 9.1667%/year
Step-by-step explanation:
Solving our equation
r = 330 / (3600 × 1) = 0.09166667
r = 0.09166667
converting r decimal to a percentage
R = 0.09166667 × 100 = 9.1667%/year
The interest rate required to
accumulate simple interest of $330.00
from a principal of $3,600.00
over 1 years is 9.1667% per year.

Which equation represents this sentence?
3 times the difference of 6 and a number is equal to 15
3x−6=15
3(6−x)=15
6−3x=15
3(x−6)=15
Answer:
B. 3(6-x)=15
Step-by-step explanation:
3 times means to multiply 3
difference means to subtract, so the difference between 6 and a number would be 6-x (x representing the unknown number)

What is the volume
Answer:
201.06 cu in
Step-by-step explanation:
Answer:
64π
Step-by-step explanation:
πr^2*h/3 is the formula for volume of a cone.
So 16pi * 12/3
Then 16pi *4
so 64 pi is the volume

Bentley was playing with 3 old dog toys and 6 new dog toys. If Bentley has 18 old dog toys how many new dog toys does he have?
Answer: 36 new dog toys
Step-by-step explanation: With the given information, we can see that Bentley has a total of 18 old dog toys. IF Bentley is playing with a proportional relationship of toys, then all we have to do is multiply 6 by 6. Since 3 times 6 is 18, we have to do 6 times 6 which is 36.

x = -7
Step-by-step explanation:
Write out the equation: 3x - 2 = -x - 30
Isolate the x

Step-by-step explanation:
= (8n² - 3n + 10) + (-3n² - 6n - 7)
= (8 - 3)n² + (-3 - 6)n + (10 - 7)
= 5n² - 9n + 3

IN A CLASS OF 60 STUDENTS, 25 PLAYS BASKETBALL, 2O PLAY VOLLEYBALL, AND 10 STUDENTS PLAY BOTH OF THEM. HOW MANY STUDENTS PLAY NEITHER BASKETBALL NOR VOLLEYBALL ?
Answer:
5
Step-by-step explanation:
60-25=35
35-20=15
15-10=5
5 people dont play either of them
Answer:
25
Step-by-step explanation:
To solve this, we can add the number of basketball players and the number of volleyball players:
25 + 20 = 45
But we know that there are ten players who are counted twice because they play both. So we subtract 10:
45 - 10 = 35
And that is the total number of students who play either basketball or volleyball. Now to figure out those that play neither sport we subtract the number of students by the number of players:
60 - 35 = 25
That’s the number of students who don’t play one of those sports.
Solve for the variable shown
Y=
Answer:
y≈94.31
Step-by-step explanation:
Hi there!
We're given a right triangle (notice the 90 degree angle), the measure of one of the legs (one of the sides that make up the right angle) as 46, the other one as y, and one of the angles as 26°
We want to solve for y
We can use a trigonometric ratio to do that.
First, let's recall the three most-well known ratios:
Sine is [tex]\frac{opposite}{hypotenuse}[/tex]
Cosine is [tex]\frac{adjacent}{hypotenuse}[/tex]
Tangent is [tex]\frac{opposite}{adjacent}[/tex]
Since we are given one of the angles, let's find out which sides are the opposite, adjacent, and hypotenuse, in reference to the given angle (the 26° angle)
In reference to that angle, the side opposite to that angle (also the side known as "opposite) is the side marked as 46, the adjacent side is y, and the hypotenuse is the unmarked side
Since we know the opposite and adjacent, let's use the ratio for tangent
Since we based our labels off of the 26 degree angle, the tangent ratio is the tangent OF 26, or tan(26)
tan(26)=[tex]\frac{46}{y}[/tex]
Now we need to solve the equation
Start by multiplying both sides by y
tan(26)*y=46
Divide both sides by tan(26)
y=[tex]\frac{46}{tan(26)}[/tex]
Plug [tex]\frac{46}{tan(26)}[/tex] into your calculator, and remember to have the calculator on degree mode
[tex]\frac{46}{tan(26)}[/tex]≈94.31
Remember that [tex]\frac{46}{tan(26)}[/tex] is equal to y, which means that y is about 94.31
Hope this helps!
