Karen got a prepaid debit card with $25 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon was 13 cents per yard. If after that purchase there was $19.28 left on the card, how many yards of ribbon did Karen buy?
44
Step-by-step explanation:
25 - 19.28 = 5.72
5.72 × 100 to change from dollar to cents
572
572 ÷ 13 = 44 yards of ribbon karen bought

The equation R=30A-50 represents the revenue R (in dollars) you make by spending A dollars on advertising. Your revenue totaled $160. How much did you spend on advertising?
Answer: $7
Step-by-step explanation:
R = Revenue = $160
$160 = 30A - 50
(+50) (+50)
210 = 30A

30 points !!!!Math please help show your workkkk i just need help with 5-8
Step-by-step explanation:
I went through all of them and also checked what you did.
1. no, wrong. I don't know how you got to the 2×7 in there.
17 - 5×4/2 = 17 - 5×2 = 17 - 10 = 7
2. we just did in the other question. it is 26.
3. correct for the approach, but mistake in the final calculation : 28 + 64 = 92 !
4. (4-7)² - 6×7 + 20
how did you get to the 26 for -6×7 + 20 ?
no.
-3² - 42 + 20 = 9 - 42 + 20 = -13
5. 2×(18 - (5 + 3²)/7)
2×(18 - (5 + 9)/7) = 2×(18 - 14/7) = 2×(18 - 2) = 36 - 4 = 32
6. ((-5 + 1)/2)³ - |‐7|
that may part means "absolute value" of -7. and you know, that means 7.
(-4/2)³ - 7 = -2³ - 7 = -8 - 7 = -15
7. 1 + (-2 - 5)² + (14-17)×4
1 + -7² + -3×4 = 1 + 49 - 12 = 38
8. (6×(2+4) - 1) / (2×3 + 1)
(6×6 -1) / (6 + 1) = 35 / 7 = 5
9. (2⁵/8 + 3) / (4 + 3)
(32/8 + 3) / (7) = (4 + 3) / 7 = 7/7 = 1
10. (17×5 - 3×5) / (3² + 1)
(14×5) / (9 + 1) (as for same factors we can contract the expressions like 17×5 - 3×5 = 14×5)
70 / 10 = 7
11. (13 + 7²/7) / (9 - 20/4 - 16)
(13 + 49/7) / (9 - 5 - 16) = (13 + 7) / (-12) = 20/-12 = -5/3
12. - |-16| / ((3² - 4) / (5 - 10))
-16 / ((9-4) / (-5)) = -16 / (5/-5) = -16 / -1 = 16

(8.7) and (5.7) slope
Answer:
0
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 7-7)/(5-8)
= 0/-3
= 0
Consider the following.
f(x) = tan(x/2)
Find the x-values at which f is not continuous. Are these discontinuities removable? (Use k as an arbitrary integer. If an answer does not exist, enter DNE.)
Answer:
Anything in the form x = pi+k*pi, for any integer k
These are not removable discontinuities.
============================================================
Explanation:
Recall that tan(x) = sin(x)/cos(x).
The discontinuities occur whenever cos(x) is equal to zero.
Solving cos(x) = 0 will yield the locations when we have discontinuities.
This all applies to tan(x), but we want to work with tan(x/2) instead.
Simply replace x with x/2 and solve for x like so
cos(x/2) = 0
x/2 = arccos(0)
x/2 = (pi/2) + 2pi*k or x/2 = (-pi/2) + 2pi*k
x = pi + 4pi*k or x = -pi + 4pi*k
Where k is any integer.
If we make a table of some example k values, then we'll find that we could get the following outputs:
x = -3pix = -pix = pix = 3pix = 5piand so on. These are the odd multiples of pi.
So we can effectively condense those x equations into the single equation x = pi+k*pi
That equation is the same as x = (k+1)pi
The graph is below. It shows we have jump discontinuities. These are not removable discontinuities (since we're not removing a single point).
Describe and correct any error a student may have made when solving the equation
0.15(y -0.2)=2-0.5(1-y).
Answer:
The student made an error during the distributive property in the second step where they multiplied 0.15 by -0.2 to equal -0.3 when it should have been -0.03.
Step-by-step explanation:
[tex]0.15(y-0.2)=2-0.5(1-y)\\0.15y-0.03=2-0.5+0.5y\\0.15y-0.03=1.5+0.5y\\100(0.15y-0.03)=100(1.5+0.5y)\\15y-3=150+50y\\15y-3-15y-150=150+50y-15y-150\\-153=35y\\-\frac{153}{35}=y[/tex]
What is the volume of the rectangular prism?
5 cm
3 cm
6 cm
Answer:
90 cm^3
Step-by-step explanation:
The equation to solve for the volume of rectangular prisms is l×w×h or length×width×height
5×3×6 is 90cm^3
Volume of a rectangular prism is :
[tex] \boxed{ \boxed{ length \times width \times height}}[/tex]

When 'x' and 'y' are in direct proportion , then the relation between 'x' and 'y' is __________
Step-by-step explanation:
If two quantities x and y vary (change) together in such a manner that the ratio of their corresponding values remains constant, then x and y are said to be in direct proportion.
6(x - 6) + x = 7(x - 7) + 13
Answer:
X = All Real Numbers
Step-by-step explanation:
Distribute: (6)(x) + (6)(−6) + x = (7)(x) + (7)(−7) +13
Multiply: 6x + −36 + x = 7x + −49 + 13
Combine like terms: (6x + x ) + (−36) = (7x) + (−49 + 13)
Simplify: 7x + −36 = 7x + −36
7x − 36 = 7x −36
Subtract 7 from both sides: -36 = -36
Add 36 to both sides: 0 = 0

3(5x + 2) + 4x = 44
Step-by-step explanation:
3(5x+2)+4x=44
1st: You would do Distributive Property
15x+6x+4x=44
Then: Combining Like Terms
15x+6x =21x+4x=25
25x=44
Divide: 44 by 25which is (1.76) but there cannot be decimals so it would be44/25Answer = 44/25 or 1.75

What is the solution to this equation?
2x + 3 (x - 10) = 45
A. x = 15
B. x = 3
C. x = 7
D. x = 11
ANSWER: A (x = 15)
Answer:
The value of x is 15
Step-by-step explanation:
2x + 3(x - 10) = 45
2x + 3x - 30 = 45
5x - 30 = 45
Now, Add 30 both sides we get,
5x - 30 + 30 = 45 + 30
5x = 75
Now, Divide 5 from both sides we get,
5x/5 = 75/5
x = 15
Thus, The value of x is 15
Hence, Option A is correct

Answer:
d=14
Step-by-step explanation:
1d/6+2/3=1(d-2)/4
Find the L.C.M.
d+4/6=d-2/4
Cross multiply
4d+16=6d-12
Collect like terms
16+12=6d-4d
28=2d
Divide through by the coefficient of d
2d/2=28/2
d=14
Answer:
d = 20
Step-by-step explanation:
1/6*d + 2/3 = 1/4*(d - 2) do the multiplying
d/6 + 2/3 = (d-2)/4 now add fraction
d/6 + 2/3 to add these up we need to multiply 2/3 with 1/2 and it will be 4/6
d/6 + 4/6 = (d+4)/6
(d+4)/6 = (d-2)/4 cross multiply
4d + 16 = 6d - 24 add like terms
16 + 24 = 6d - 4d
40 = 2d divide both sides by 2
20 = d
