Answers
Answer:
x = 3
y = 2
Step-by-step explanation:
5x - 3 = 6y
5x + 3 = 9y
y = 5/6 x - 1/2
5x + 3 = 15/2 x - 9/2
-5/2 x + 15/2 = 0
-5/2 (x - 3) = 0
x = 3
Answer:
x = 3
y = 2
Step-by-step explanation:
because it's a rectangle, opposite sides are equal
AD = BC
AB = DC
so we can use their measures to create a system of equations:
5x + 3 = 9y
5x - 3 = 6y
if we multiply the first equation by -1 we can eliminate the x-values:
-(5x + 3 = 9y)
-5x - 3 = -9y
+ 5x - 3 = 6y
-6 = -3y
y = 2
If y = 2 then BC = 12 and we can set up this equation:
12 = 5x - 3
15 = 5x
3 = x

Brandon took a 50-question exam worth a total of 160 points. There were x two-point questions and y five-point questions. How many of each type of question were on the exam?
Answers
Answer:
35 2-point questions, and 15 5-point questions
Assume x 2-points question, so 50-x 5-points question
Total no of points: 2*x+5*(50-x)=145 points
2x+250-5x=145
-3x=-105
x=-105/-3=35 2-points questions
Remaining 50-35=15 5-points questions

There are 30 two-point questions and 20 five-point questions.
What is equation?
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
According to questions, Brandon took a 50-question exam worth a total of 160 points.
There were x two-point questions and y five-point questions.
So,[tex]y=50-x[/tex]
Now, according to question, we will get the following equations
[tex]2x+5(50-x)=160[/tex]
⇒[tex]2x+250-5x=160[/tex]
⇒[tex]-3x=-90[/tex]
⇒[tex]x=30[/tex]
[tex]y=50-30\\[/tex]
⇒[tex]y=20[/tex]
Hence, we can conclude that there are are [tex]30[/tex] two-point questions and [tex]20[/tex] five-point questions.

An airplane company is determining the difference in selling price if rows of first-class seats are added to a new design. Using the average selling price of $1,000 per first-class seat, the total selling price for one new row is
f(r) = 4,000r. Each row in first class eliminates two rows of economy seats. Using the average selling price of $150 per economy seat, the total price for each pair of removed rows is e(r) = 1,800r.
Which is d(r), the profit or loss for adding r rows of first class seats?
A. d(r) = 2,200r
B. d(r) = 5,800r
C. d(r) = –2,200r
D. d(r) = –5,800r
Answers
Step-by-step explanation:
From the original question, we can rewrite this as:
An airplane company is determining the difference in selling price if rows of first-class seats are added to a new design. The total selling price for one new row is f(r) = 4,000r. Each row in first class eliminates a pair of rows of economy seats. The total price for each pair of removed rows is e(r) = 1,800r. Which is d(r), the profit or loss for adding r rows of first class seats?
f(r) = 4000r
e(r) = 1800r
d(r) = ? (profit or loss)
Assuming we had added a row of first class seats,
+ f(r) = 4000r
But we had to remove a pair or rows from the economy seats,
- e(r) = 1800r
Translating these into one equation:
d(r) = f(r) - e(r) = 4000r - 1800r = 2200r
Therefore, OPTION A.) d(r) = 2200r
The value of d(r) will be 2200r. The correct option is A.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Magdala is modeling 2.12÷4 how to cheeks change the place value blocks so she can make 4 equal shares
Answers
Answer and explanation:
If Magdala is trying to divide 2.12 by 4 then she would definitely need to change the place value of the dividend(2.12) and the divisor(4). In other words, both numbers need to be whole numbers.
To make 2.12 a whole number, we shift the decimal point two places to the right of the decimal point to get 212. We do same for 4 to get 400, since both numbers have to have their place values adjusted equally.
We divide 212 by 400 to get 0.53
Therefore 2.12 divided by 4= 0.53

Answers

Answer:
UV is not the midline. (The midline length is 4.5.)
Step-by-step explanation:
The trapezoid midline is the average of the lengths of the bases. Here, the midline length would be ...
(7 ft +2 ft)/2 = (9 ft)/2 = 4.5 ft
The line length shown is 3.5 ft, so the segment shown is not the midline.
