David sells small, medium, and large bags of mints at his store. A medium bag contains three times as many mints as a small bag. A large bag contains five times as many mints as a medium bag • There are 3,510 mints in a large bag. How many mints are in a small bag?
Answer:
This is lowkey hard
Step-by-step explanation:
Answer:
234 mints
Step-by-step explanation:
if you represent small as s, medium as m, and large as l, you can write the equations as 3s=m 5m=l and 3510=l. We can then substitute 3510 for l and get 5m=3510 divide by 5 and get m=702 put that in the other equation and get 3s=702 divide by 3 and get s=234
A business has $11,080 to spend on new laptops and tablet computers for its salespeople. The laptops cost $515 each. The tablets cost $285 each. The business wants each salesperson to have either a laptop or a tablet. There are 30 salespeople. Create a system of equations that models how many of each type of computer the business should buy.
515x + 285y = 11,080
x + y = 30
515x + 285y = 30
x + y = 11,080
515x + y = 30
x + 285y = 11,080
x + 285y = 30
515x + y = 11,080
Answer:
515x + 285y = 11,080
x + y = 30
Step-by-step explanation:
x= Amount of laptops
y= Amount of tablets
Answer:
Your answer would be A
Step-by-step explanation:
515x + 285y = 11,080
x + y = 30

Solve -6x - 7 = 17.
X=_
Answer:
x=-4
Step-by-step explanation:
-6x=17+7
-6x=24
x=-4
Answer:
x = -4
Step-by-step explanation:
Add 7 to each side of the equation (left and right of the equal sign) which should get you to -6x = 24. Then multipy both sides by -1 to make the -6x positive and turn the 24 negative. That should leave you with 6x = -24, then divide by 6 on each side and your answer should be x = -4
How are ROC (rate of change) and slope related AND different

This is a pretty mathematical question, so I will answer it in pieces as I get the time to work it out. To find the time it takes to fall, you start with Newton's second law, ma=m[d2r/dt2]=-GMm/r2=dv/dt and integrate it once to get v=dr/dt=√[2GM(R-r)/(Rr)] where, for your question, R is the distance from the center of the earth to the point from which it was dropped, r is where it is at the time t(r), G is the universal gravitation constant, and M is the mass of the earth. (The mass m of the ship does not matter.) (You can more easily get v(r) from energy conservation.) Next integrate v(r)=dr/dt to get t(r)=-2.69x105{0.5tan-1((2x-1)/(2√[x(1-x)]-√[x(1-x)]-π/4} where x=r/R; this is not a simple integral to perform, but you can find good integrators on the web, for example Wolfram Alpha. Once you have gotten the indefinite integral you are not finished, you need to find the integration constant which will put the ship at rest at x=r/R=1; that is where the π/4 comes from. Putting in your numbers, I find t=4.22x105 s=117 hr=4.89 days. The figure shows the graph of t(x).

Answer:
3948 members
Step-by-step explanation:
SInce a is the initial amount, a = 2000. b represents growth factor, and the amount increases by 12% every year, so b = 1.12. Since you want to find the value in 6 years, x= 6. Therefore your equation is y = 2000 • 1.12 ^ 6. Plug it into your calculator and you get y = 3947.64, and since they are people you round up to 3948 members.
A football team loses an average of 3 yards per play. How many yards
have they lost after 4 plays? Write a number sentence to show your
answer.
The expression would be:
3x
x=number of plays
Insert 4:
3(4)
=12
They would 12 yards after 4 plays if losing 3 yards every play.
The amount of yards the football team loses after 4 plays is given by the equation A = 12 yards
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the amount of yards the football team loses after 4 plays be A
Now , the equation will be
Let the amount of yards the football team loses per play = 3 yards
So , the amount of yards the football team loses after 4 plays = 3 x amount of yards the football team loses per play
Substituting the values in the equation , we get
The amount of yards the football team loses after 4 plays A = 3 x 4
On simplifying the equation , we get
The amount of yards the football team loses after 4 plays A = 12 yards
Hence , the amount of yards is 12 yards

The measure of angle Q is 75 degrees. Find the measure of angle P
Answer:
m<P = 30°
Step-by-step explanation:
∆PQR has two equal sides. An isosceles ∆ has two equal sides and the angles opposite the two equal sides are congruent to each other.
Thus, we can conclude that ∆PQR is an isosceles ∆ with two equal base angles, <P and <Q.
Since m<Q = 75°, therefore, m<R = 75°.
m<P = 180 - (75 + 75) (sum of ∆)
m<P = 30°
