Answer:
They say that the sum of the two numbers (x and y) is 64, so we can write our first equation by adding them and setting that sum equal to 64:
x + y = 64
The question also tells us that their difference is 14. Similarly to before, we'll just subtract the two numbers and set that difference equal to 14:
x - y = 14
Now from here, you know how to continue with substitution to find the values for x and y. Just remember when you get a word problem to break it down and look for key words like sum, difference, or product, and from there you'll be able to build your system of equations.

5(k + 4) - 2k
Answer:
3k + 20
Step-by-step explanation:
5(k + 4) - 2k
First distribute
5k + 20 - 2k
Then subtract (combine) the like terms
3k + 20
Answer:
The answer is 3k + 20
Step-by-step explanation:
5k + 20 - 2k
Combine like terms: 5k - 2k = 3k
which makes your answer 3k + 20

Answer:
a)[tex]-\frac{1}{12}[/tex]
d)[tex]-\frac{1}{8}[/tex]
Step-by-step explanation:
a) Find a common denominator. 12 (3 × 4 = 12)
Convert the fractions to have a denominator of 12.
[tex]\frac{2}{3}[/tex] → [tex]\frac{8}{12}[/tex]
[tex]\frac{3}{4}[/tex] → [tex]\frac{9}{12}[/tex]
[tex]\frac{8}{12}[/tex]- [tex]\frac{9}{12}[/tex] = [tex]-\frac{1}{12}[/tex]
d) Find a common denominator. 8 (4 × 2 = 8; 8 × 1 = 8)
Convert the fractions to have a denominator of 8.
[tex]\frac{3}{4}[/tex] → [tex]\frac{6}{8}[/tex]
[tex]\frac{5}{8}[/tex] → [tex]\frac{5}{8}[/tex]
- [tex]\frac{6}{8}[/tex] - (-[tex]\frac{5}{8}[/tex])=?
Remember, 2 subtractions signs cancel each other out.
- [tex]\frac{6}{8}[/tex] + [tex]\frac{5}{8}[/tex] = [tex]-\frac{1}{8}[/tex]
You purchase 2 action figures per week. You have 48 action figures, which is 75% of the total number of action figures you need to complete your collection. How many weeks until your collection is complete?
Answer:
Step-by-step explanation:
Let the total number of action figures = x
75% of x = 48
[tex]\dfrac{75}{100}*x=48\\\\Multiply \ by \ 100\\\\75*x =48*100\\\\Divide \ by \ 75\\\\x=\dfrac{48*100}{75}\\\\\\x=16*4\\\\x= 64[/tex]
Remaining action figures need to be collected = total figures - number of action figures I have
= 64 - 48 = 16
Number of weeks = 16 ÷ 2 = 8
It will take 8 weeks to collect 16 action figures.

Analyze the zeros of f(x) =x^4 - 3x^3 - 2x^2 + 3x - 5.
Evaluate the function at the given values.
h(x) = x² – 3x + 2
a. h(2)
b. h(-2)
c. h(0)
a. h(2)=
Answer:
h(2) =0
h(-2) =4
h(0) = 2
h(2) = 0
Step-by-step explanation:
h(2) = 2^2-3(2)+2 =4 - 6 + 2 = 0
h(-2) = 2^-2 -3(-2) +2 = -4+ 6+2=4
h(0) =0^2 - 3(0)+2 = 0-0 +2 = 2
h(2) = 2^2-3(2)+2 =4 - 6 + 2 = 0

What's the answer?????
Answer:
0
Step-by-step explanation:
basically plug a and b back into the equation so (0)÷(48) will equal 0 which is equal to C because 0 out of any number is always equal 0 because you're not taking taking any value out of it
Answer:
Step-by-step explanation:
zero is always a nasty piece of work. You need to be careful how you handle it. What do you get when you divide 0 by 48?
Answer, you don't get anything because no matter if b is 1 or 48, you get 0 as the result.
Answer: B
Middle-school students sold cookies in packages of 12. On the first day, they sold x packages. On the second day, they sold twice as many packages as on the first day. Which expression shows the number of cookies they sold on the second day
Answer:
2x

Let $f(x) = 12x^9 + x$. Find $f(3) + f(-3)$.
Answer:
Ok, here goes: f(3) means take f(x) and plug in 3 wherever we see x. So
f(3) = 12*39 + 3 = 236196 + 3
f(3) = 236199
Likewise, f(-3) means take f(x) and plug in (-3) wherever we see x. So
f(-3) = 12*(-3)9 + (-3) = -236196 - 3
f(-3) = -236199
Putting those two things together, we get
f(3) + f(-3) = 236199 - 236199 = 0

10-5: Practice Buddy answers
Answer:
Step-by-step explanation:
how much money did she have at first
Step-by-step explanation:
x = the total money she had first.
x - x×1/4 - (x - x×1/4)×1/2 = 15
you see, first we needed to deduct 1/4 of x from x. that left us with (x - x×1/4). and from that we need to deduct 1/2.
now, we can simplify :
(x - x×1/4) = (x×4/4 - x×1/4) = x×3/4
x×3/4 - x×3/4 × 1/2 = 15
x×3/4 - x×3/8 = 15
we multiply both sides by 8 (4 is a factor of 8, so this handled both fractions perfectly) :
x×3×2 - x×3 = 120
6x - 3x = 120
3x = 120
x = $40
she had $40 at the beginning.
