TIMED TEST WILL GIVE BRAINLIEST PLEASE
Sunny has $4.80 in quarters and dimes. The number of dimes she has is 4 more than 3 times the number of quarters. Which system of equations represents this scenario?
A: 0.01x + 0.25y = 4.80
y = 3x + 4
B: 0.01x + 0.25y = 4.80
x = 3y + 4
C: 0.1 + 025y = 4.80
y = 3x + 4
D: 0.1 + 0.25y = 4.80
x = 3y + 4
Answer:
Step-by-step explanation:
c
The system of equations representing the scenario given are x = 3y + 4 and 0.25y + 0.1x = 4.8.
What does a System of Linear Equations define?Linear equations involve one or more expressions including variables and constants and the highest exponent of the variable is 1.
System of linear equations involve two or more linear equations.
Let y be the number of quarters and x be the number of dimes.
Given, number of dimes she has is 4 more than 3 times the number of quarters.
x = 3y + 4
Also, we have that, Sunny has $4.80 in quarters and dimes.
We know,
1 dollar = 4 quarters
⇒ 1 quarter = 1/4 = 0.25 dollar
1 dollar = 10 dimes
⇒ 1 dime = 1/10 = 0.1 dollar
So, we get another equation,
0.25y + 0.1x = 4.8
Hence the system of equations are x = 3y + 4 and 0.25y + 0.1x = 4.8.

Step-by-step explanation:
If you bought 24 light bulbs, how much money would you save by buying the less expensive light bulbs?
with the more expensive light bulbs, the cost would be $155.52
with the less expensive light bulb, the cost would be $119.04
This means you would save $36.48
Answer:
$3.84 is the amount you save by purchasing the cheaper lightbulbs when buying 24.
Step-by-step explanation:
Alrighty, so!
With this one, I broke down the price per lightbulb (divided the money by the amount of bulbs in the package).
$4.96/4= $1.24/bulb
$6.48/6= $1.08/bulb
I then multiplied that amount per bulb by 24.....
$1.24 x 24 = $29.76
$1.08 x 24 = $25.92
.... And subtracted the lower number from the higher number to get the answer.
$29.76-$25.92= $3.84
Hope this helps :D

Answer:
3 slices each
Step-by-step explanation:
One whole pizza is most commonly 8 slices.
1/8 is one slice
1/4 is two slices
1/2 is four slices
Knowing these values we can use subtraction and division to find the answer.
Since 1/4 is 2, we subtract 2 from 8
8 - 2 = 6
Now since there 2 people splitting it, you divide it by 2 or multiply it by 1/2
Doing so will get you 3 which is the answer

Part of the population of 6,750 elk at a wildlife preserve is infected with a parasite. A random sample of 50 elk shows that 11 of them are infected. How many elk are likely to be infected?
Based on the sample, there will likely be
infected elk in the wildlife preserve.
Answer:
1485 are likely to be infected.
Based on the sample, the probability of an elk being infected is 11/50. Multiply this by the number of elk:
11/50(6750) = 1485.
32 divided by 4 x (16 x 1/2) - 2
easy answer pls i need to show my work
Answer:
b
Step-by-step explanation:
The value of the expression 32 divided by 4 x (16 x 1/2) - 2 is 30.
What is Equation?Equation is collection of two or more expressions with an Equal sign.
By using PEMDAS rule we solve the expression by following certain operations.
The first step is to solve the expression with in parenthesis.
16 x 1/2 = 8
Now the expression becomes as follow.
32/4 x (8) - 2
Now let us multiply four and eight.
4 x 8 = 32
Therefore, the expression becomes:
32 - 2
Now we use Subtraction
32 - 2 = 30
Therefore, the value of the expression is 30.
