Is my answer correct?
Answer:
yes $56 is correct
Step-by-step explanation:
The 3 part of the ratio relates to $42 , then
$42 ÷ 3 = $14 ← value of 1 part of the ratio , then
4 parts = 4 × $14 = $56
Write a word problem for this equation: $14 - x = $3
Answer:
$14 - x = $3
Step-by-step explanation:
$14 - x = $3

Shelly and Terrence earned points in a game by come playing various tasks. Shelly completed x tasks and scored 90 points on each one. The expression below shows Terrence’s total points in the game:
90x - 20
What does the constant term of expression represent?
Answer:
The correct answer to the question is:
The difference between Shelly's and Terrence's total points.
Answer:
B
Step-by-step explanation:
The answer or the only choice you could pick, is D.
But it is not correct - not really.
The question says that 90x - 20 represents Terrence's points. Only if D is correct does 20 show his tasks. The question must have 2 answers.
So which one do you pick? You should never have to deal with this kind of question. The answer I think you need to give is B, but I wouldn't bet the farm on it.
The question should say 90*x - 20 has Terrence's tasks in it. Then the answer is B.
At a school camp there is enough food for 150 students for 5 days.
a How long would the food last if there were only 100
students?
Answer: 7.5 days or 7 days (round down)
Step-by-step explanation:
STEP ONE: Find the total number of food in 5 days
150 students
5 days
150 × 5 = 750 unit of foods
In another word, there is enough food for 750 students in one day.
STEP TWO: Find the days this amount of food would last for 100 students
750 unit of food
100 students
750 ÷ 100 = 7.5 days
7.5 (round down) = 7 days
**Disclaimer** Rounding down to 7 days means that these food are enough for all 100 students for a whole day. If keeping 7.5 days, this would mean either the students would not be full, or there would only be half of the student body could get food. From my knowledge, I would round down. HOWEVER, this all depends on the rules that you would apply in mathematics.
Hope this helps!! :)

Solve for x

Step-by-step explanation:
There are several methods to solve equations of the type AX = XB. These type of equations occur in domains like robotics, for which solutions have been proposed like the Tsai and Lenz method [IEEE 1987], for example. 1) I feel solving the equation XA = XB is not the same as solving the known form AX = XB. Am I right? 2) Neither can it be solved like the Sylvester equation, because even that requires AX+XB=CAX+XB=C form. What i have is XA=XBXA=XB, a redundant set of equations. That is,
A1.XA2.XAn.X=X.B1=X.B2⋮=X.BnA1.X=X.B1A2.X=X.B2⋮An.X=X.Bn
If i am correct, these could be rewritten into another form like AX=BXAX=BX. Should i rewrite the equation and try to solve this problem using any other existing methods?

At a day care center for toddles there is one
teacher for every 7 toddlers. Determine
whether there is a direct variation between
the number of toddlers, y, and the number of
teachers, x. If so, find the equation of direct
variation.
Answer: x = 7y.
Step-by-step explanation: There is direct variation between the number of toddlers and the number of teachers. We know this because when one increases, the other would as well. We can write the equation of direct variation as x = 7y.

What is the value of the expression 5¼(-10.2)? Record your answer and be sure to use the correct place value.
The value of the given expression is - 53.55
[tex]5 \frac{1}{4}( - 10.2) \\ [/tex]
The bracket implies multiplication :
Hence,
[tex]5 \frac{1}{4}( - 10.2) \\ [/tex] = [tex]5 \frac{1}{4}\times - 10.2
Converting the fraction to improper :
[tex] \frac{21}{4} \times - 10.2[/tex]
Then, to decimal :
[tex]5.25 \times - 10.2 = - 53.55[/tex]
Hence, the value of the expression is - 53.55

The diagram shows 3 identical circles inside a rectangle.
Each circle touches the other two circles and the sides of a rectangle, as shown in the diagram.
The radius of each circle is 2 mm.
Work out the exact area of the rectangle. Give your answer in the form
[tex]a \sqrt{3} + b[/tex]
where a and b are integers.
Answer:
as the diagram is not provided by you
Step-by-step explanation:
proper an answer cannot be written if the three circles touch Each Other as well as the the sides of the rectangle it means that rectangles length and breadth are made by attaching to circles together which means that length and breadth of the rectangle are equal therefore length is equal to diameter of one circle into two that is 8 therefore length and breadth of the rectangle are 8 each other for exact area of rectangle is 8 x 8 = 64
