A math student goes to an office supply store and purchases a total of 16 spirals and pencils. Each spiral costs $3. 50, and each pencil costs $1. 25. If the student spent a total of $29, how many pencils did the student purchase?.
Answers
The student purchase 12 pencils
Let the total number of pencils purchased be xLet the total number of spirals purchased be yIf a math student goes to an office supply store and purchases a total of 16 spirals and pencils, then;
x + y = 16 .................. 1
If each spiral costs $3. 50, and each pencil costs $1. 25 and the student spent a total of $29, hence;
1.25x + 3.5y = 29 ................. 2
Solve both equations simultaneously
x + y = 16 .................. 1 * 1.25
1.25x + 3.5y = 29 ................. 2 * 1
__________________________________
1.25x + 1.25y = 20.
1.25x + 3.5y = 29
Subtract both equations
1.25y - 3.5y = 20 - 29
-2.25y = -9
y = 9/2.25
y = 4
Substitute y = 4 into equation 1:
x + y = 16
x = 16 - 4
x = 12
This means that the student purchase 12 pencils

Need help with this math problem
Answers
Answer:
A)
Step-by-step explanation:
Given expression:
[tex] \boxed{\mathsf{c = 15 + am}}[/tex]
subtracting 15 from both sides, and combining like terms on the RHS
[tex] \implies\mathsf{c - 15 = (15 - 15)+ am}[/tex]
Dividing both sides by a
[tex] \implies\mathsf{ \frac{c - 15}{a} = am \times \frac{1}{a} }[/tex]
a On the RHS gets canceled for being present in both Numerator as well as denominator, and were left with the following equation:

Answer:
Option D
Step-by-step explanation:
Since they are in proportion. So,
27 : 36 :: 9 : x
27 × x = 36 × 9
x = 36 × 9/27
x = 12 × 1
x = 12

The half life of a radioactive substance is 10 years. If 64 grams are placed in a
container, how much will remain after 50 years?
Answers
Answer:
2 grams
Step-by-step explanation:
50 years is 5 half lives as 1 half life is 10 years.
64 divide 2 = 32-1 half life
32 divide 2 =16-2nd half life
16 divide 2 = 8-3rd half life
8 divide 2 = 4-4th half life
4 divide 2 = 2-5th half life
This means we will have 2 grams left of the radioactive substance after 50 years.

Grocery Store A is selling bananas for $0. 75 for 12 pound. Grocery Store B is selling 5 pounds of bananas for $3. 75. Which store is offering the best unit rate? Show your work.
Answers
The store is offering the best unit rate is Grocery Store A.
The store with the lower unit rate offers the best rate. The unit rate is the total cost divided by the pound of bananas sold.
unit rate = cost / pounds
Unit rate of Grocery Store A: $0.75 / 12 = $0.0625
Unit rate of Grocery Store B: $3.75 / 5 = $0.75
Comparing the unit rates of both stores, Grocery Store A offers a lower unit rate.
