Answer:
c) (-3s) - 9
Step-by-step explanation:
(-5s) + 2s - 9
-5s + 2s - 9 <== combine like terms
-3s - 9
Therefore, our answer is c.
Hope this helps!
Answer:
the answer is C.
Step-by-step explanation:
Start by combining like terms (-5s) and 2s= (-3s)
You can't subtract 9 from this because they aren't like terms.
(-3s) -9

Solving the Question
We're given:
There were 478 people in total.$1.75 per child$2.25 per adultTotal revenue of $975We must find the number of children and adults who swam.Set variables:Let a represent the number of children who swam.
Let b represent the number of adults who swam.
Create equationsBecause we've set two variables, we need two equations to be able to find the answers.
One of the equations will regard price while the other will regard the number of people, as those are the two things given in the question.
Number of people:
[tex]a+b=478[/tex]
The number of children + the number of adults = 478 in totalPrice:
[tex]1.75a+2.25b=975[/tex]
$1.75 per child + $2.25 per child = $975 in totalSolve equations[tex]a+b=478[/tex][tex]1.75a+2.25b=975[/tex]We can solve this question using substitution, where we plug one equation into the other.
Isolate a in the first equation:
[tex]a+b=478\\a=478-b[/tex]
Plug the first equation into the second equation by replacing a:
[tex]1.75a+2.25b=975\\1.75(478-b)+2.25b=975[/tex]
Solve for b:
[tex]1.75(478-b)+2.25b=975[/tex]
⇒ Open up the parentheses:
[tex]836.5-1.75b+2.25b=975\\836.5-0.5b=975[/tex]
⇒ Subtract 836.5 from both sides to isolate b:
[tex]-0.5b=138.5[/tex]
⇒ Divide both sides by -0.5:
[tex]b=277[/tex]
Therefore, there were 277 adults in total.Solve for a:
[tex]a+b=478[/tex]
⇒ Replace b with 277:
[tex]a+277=478\\a=201[/tex]
Therefore, there were 201 children in total.Answer
There were 201 children and 277 children at the pool that day.

Answer: 235 cm^2
Explanation: you can cut the shape into two smaller ones and then solve for each smaller shapes area. to find out the length of the top piece with 11 as length you can subtract nine from fourteen. from their you calculate the area of the top shape (11x5=55) and then the bottom shape (9x20=180). from their just add the two areas to get 235.
Answer:
246 cm squared
Step-by-step explanation:
u hv to break up the big shape into little shapes so you would do 20x9 and 20-14 which is 6 and do 6x11 and then add them up

Part 1
Your class is selling boxes of flower seeds as a fundraiser. The total profit p depends on the amount x that your class charges for each box of seeds. The equation p= -0.5x²+25x-111 models the profit of the fundraiser. What's the smallest amount, in dollars, that you can charge and make a profit of at least $114?
Answer:
12
Step-by-step explanation:
if we know we want a profit of at least 114, we need to solve for x.
if we put 12 for x we get the answer 117 and when we put 11 for x we get less than 114.
-0.5(12)^2 + 25(12)-111 = 117

alan would take 5 hours to build the wall of a house, and gavin would take 7 hours to build it alone. when they work together, they talk a lot, and their combined output decreases by 26 bricks per hour. working together, they build the wall in 4 hours. how many bricks are in the wall?
Answer:
96 bricks
Step-by-step explanation:
Alan does 1/5 of the job in an hour. Gavin does 1/7 of the job in an hour
Together, 12/35 of the job should be done in an hour. In [tex]2 \frac{11}{12}[/tex] hours, the work should be done.
rate at 4 hours=[tex]2 \frac{11}{12}[/tex]*(normal speed-26)
To clarify, x=the normal rate
4 hours(normal rate-26)=[tex]2 \frac{11}{12}[/tex](normal rate)
4(x-26)=[tex]2 \frac{11}{12}[/tex]x
x=96

The given inequality y < -4 is shown in the attached graph. The correct answer would be an option (B).
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
Inequalities with "< or > "symbols are shown with a dashed line to indicate that the line is not inside the area. Inequalities involving symbols are depicted with a solid line to indicate that the line is included in the region.
We have been the given inequality y < -4
Rearrange the equation such that "y" is on the left and all other variables are on the right.
Plot the "y=" line (a solid line for y or y, and a dashed line for y or y>). The shade above the line for a "greater than" (y> or y), or below the line for a "less than" (y or y).
Hence, the given inequality y < -4 is have shown in the attached graph.

Answer: 909.03
Step-by-step explanation:
We know that the equation is an exponential function, it can be written as y=ab^x
[tex]100 &=a b^{6.5} \dots \mathrm{Equation \ 1} \\11 &= a b^{1} \\[/tex]
[tex]\Rightarrow ab^1=11[/tex]
[tex]\Rightarrow \frac{ab^1}{b}=\frac{11}{b};\quad \:b\ne \:0[/tex]
[tex]\Rightarrow a=\frac{11}{b}[/tex]
a = 11/b, substitute it in equation 1
[tex]100 &=a b^{6.5}[/tex]
[tex]\Rightarrow 100=\left(\frac{11}{b}\right)b^{6.5}[/tex]
[tex]\Rightarrow 100b=11b^\frac{11}{2}[/tex]
[tex]\Rightarrow 11\sqrt{b^{11} } =100b[/tex]
[tex]\Rightarrow \sqrt{b^{11} } =\frac{100}{11}}[/tex]
[tex]\Rightarrow \sqrt{b^{11} } =\frac{100}{11}}[/tex]
[tex]\Rightarrow {b^{11} } =\frac{10000}{121}}[/tex]
[tex]\Rightarrow {b} =\frac{\sqrt[11]{10000 \cdot 11^9} }{11}[/tex]
[tex]\Rightarrow {b} = 1.49379[/tex]
a = 11/b
a = 11/(1.49379)
a = 7.36382
Equation: y = (7.36382)(1.49379)^x
Now plug in 12 for x:
[tex]\Rightarrow { \left(7.36382\right)\left(1.49379\right)^{12}[/tex]
[tex]\Rightarrow 7.36382\cdot \:1.49379^{12}[/tex]
[tex]\Rightarrow 7.36382\cdot \:123.44530\dots[/tex]
[tex]\Rightarrow 909.03[/tex]
Therefore, f(12) = 909.03 for the exponential function

Answer:
The answer is the second figure on the top of the page.
Step-by-step explanation:
That's because the square is 8mm x 8mm
so the figure that has a square and 8mm x 8mm is the second one in the first row.

Please answer the question.
Clarissa is making punch for a party. She mixes 64 fluid ounces of orange juice, 64 fluid ounces of pineapple juice, and 36 fluid ounces of apple juice.
Let p represent the total amount of punch that Clarissa mixes.
Which equations could be used to find the value of p?
Select each correct answer.
A.64 + 64 + 36 = p
B.64 × 2 + 36 = p
C.64 × 64 × 36 = p
D.64×2−36=p
E.64+64−36=p
Answer: A and B.
Step-by-step explanation: The first option works because Clarissa is adding 64 fluid ounces of both orange and pineapple juice and 36 fluid ounces of apple juice which makes it an addition problem. Option B works as well because it is similar to option A, only it shortens the problem by multiplying 64 twice, because 64 pops up twice. Options C, D, and E don't work because it doesn't include taking away any juice or multiplying it in immense amounts, so that's why those are wrong.
Hope this helps! :)
