A science teacher ordered S2278 worth of microscopes and dissection kits for the new science lab. A total of
26 microscopes and 56 dissection kits were ordered. A microscope costs three times as much as a dissection
kit. Write a system of linear equations that represents this situation. What is the cost of each item?
Answer:
[tex]26M + 56D = 2278[/tex] ---- equation 1
[tex]M = 3D[/tex] ---- equation 2
A microscope costs S51 and a dissection kit costs S17
Step-by-step explanation:
Given
Represent microscope with M and Dissection kits with D
Cost:
[tex]M = 3D[/tex]
[tex]Total = 2278[/tex]
Required
Represent as an equation:
To do this, we represent the equation in terms of cost and quantity
In terms of cost, we have:
[tex]26M + 56D = 2278[/tex] ---- equation 1
and
[tex]M = 3D[/tex] ---- equation 2
Substitute 3D for M in equation 1
[tex]26*3D + 56D = 2278[/tex]
[tex]78D + 56D = 2278[/tex]
[tex]134D = 2278[/tex]
Divide both sides by 134
[tex]D = \frac{2278}{134}[/tex]
[tex]D = 17[/tex]
Substitute 17 for D in [tex]M = 3D[/tex]
[tex]M = 3 * 17[/tex]
[tex]M = 51[/tex]
Hence:
A microscope costs S51 and a dissection kit costs S17

what is 5/6 rounded to the nearest hundredth?
Answer:
0.83
First, we convert the fraction to a decimal number by dividing the numerator by the denominator:
5 / 6 = 0.833
There are two parts to the decimal number above:
Integer Part: 0
Fractional Part: 833
Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*
In this case, Rule I applies, so 5/6 (or 0.833) rounded to the nearest hundredth in decimal format is:
0.83

Step-by-step explanation:
after giving 8 apples to her friend, John finds notices that two third of the remainder is 12.how many appledid she have all tigether
Answer:
26
Step-by-step explanation:
It started with x apples.
8 were given away.
Now there are x - 8 apples.
Two thirds of the remainder is (2/3)(x - 8).
That is equal to 12.
(2/3)(x - 8) = 12
x - 8 = 18
x = 26
There were originally 26 apples.
Answer:
26, if I understood the question correctly.
John has an amount of apples, gave 8 to her friend, and noticed that two thirds of the remainder is a dozen.
Step-by-step explanation:
If 2/3 of the remainder is 12, then we can set this up as an algebraic equation to see what the remainder started with.
x*2/3=12
Now we can see that we need to divide the 2/3 to get the answer for what x is equal to.
[tex]x=12/(\frac{2}{3} )[/tex]
To divide fractions, you multiply by the reciprocal, (or the fraction upside down)
[tex]x=12*(\frac{3}{2})[/tex]
When we multiply 12 by 3/2, we get 36/2, and when we reduce, we get 18.
If the entire remainder is 18, then the original total would be 18 plus the 8 that John gave to her friend.
18+8=26
Kind of a strangely worded question, I hope I understood correctly
You and your mom enter a drawing with 3 different prizes. The prizes are
awarded at random.
If a total of 10 people entered the drawing, in how many ways can you win
first prize and your mom win second prize?
a. 8
b. 2
c. 10
d. 1
Answer:
The correct answer is 8.
Step-by-step explanation:
There are 2 ways that you can win first prize and your mom can win the second prize.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
There are 10 people who entered the drawing.
Since the prizes are awarded at random, the probability of you winning the first prize is 1/3, and the probability of your mom winning the second prize is 1/2.
We can use the multiplication principle of counting to find the number of ways that you can win first prize and your mom can win the second prize.
The number of ways that you can win first prize is 1 since there is only one first prize and you are one of the 10 people who entered.
Once the first prize winner is chosen, there are 9 people left, and the number of ways that your mom can win the second prize is 1 out of 9.
The total number of ways that you can win first prize and your mom can win the second prize is:
1 × 1/3 × 1/2 × 9 = 3/2
However, the answer cannot be a fraction or decimal, since we are counting the number of ways in which events can occur.
Therefore, we round up to the nearest integer and get:
3/2 ≈ 2
Therefore,
There are 2 ways that you can win first prize and your mom can win the second prize.

Answer:

Answer:
Perform the indicated multiplication: 2 - 3x - 12 = 9 - 3x
Gather all the x terms on one side and all the constants on the other:
-3x + 3x = 9 + 12 - 2, or 0 = 19
since this is never true, 2 - 3x - 12 = 9 - 3x has no solution.
