Vicki has 210 baseball cards and buys an additional 15 cards every week. Jeb has 275 baseball cards and buys an additional 10 cards every week. After how many weeks will Vicki and Jeb have the same number of baseball cards?
Answer:
After 13 weeks, Vicki and Jeb will have the same number of baseball cards.
Step-by-step explanation:
Let n be the required number of weeks after which Vicki and Jeb have the same number of baseball cards.
The number of cards Vicki will buy after n weeks = 210 + 15n
The number of cards Jeb will buy after n weeks = 275 + 10n
Since, these are equal,
210 + 15n = 275 + 10n
15n - 10n = 275 - 210
5n = 65
Divide both sides by 5.
n = 13.
Hence, after 13 weeks, Vicki and Jeb will have the same number of baseball cards.

I need help with this question.
Michael needs to wrap a gift that is shaped like a triangular pyramid. Each face has an area of 25 in². What is the surface area? (Hint: Figure out how many faces a triangular pyramid has)
If the answer is 75 ft², color is black if the answer is 100 in², color is red
A triangular pyramid is a pyramid having a triangular base. It has 4 faces, 6 edges and 4 vertices.
Since the area of one face is 25 [tex] in^{2} [/tex]
Therefore, surface area of triangular pyramid = 4 [tex] \times [/tex] area of one face
= [tex] 25 \times 4 [/tex]
= 100 [tex] in^{2} [/tex].
So, the surface area of triangular pyramid is 100[tex] in^{2} [/tex].
Therefore, color is red.
What is the gcf of 18 and 14
what is the value of x in circle c
Answer:
If two secant segments intersect outside a circle, then the product of one secant segment with its external portion equals the product of the other secant segment with its external portion. So we have:
10(10) = 5(3x + 5)
100 = 15x + 25
15x = 75
x = 5

Answer:
1/9, 1/8 and 1/4
Step-by-step explanation:
multiply the both given numerators (top numbers) and both given denominators (bottom numbers) given bellow
1/3 x 1/3 = 1/9 because 1 x 1 = 1 and 3 x 3 = 9
1/4 x 1/2 = 1/8 because 1 x 1 = 1 and 4 x 2 = 8
3/4 x 1/3 = 3/12 or 1/4 simplified because 3 x 1 = 3 and 4 x 3 = 12. when you simplify you divide the denominator by the numerator and 12 divided by 3 is 4 and you the 4 stays as the denominator and make the numerator of 1
