Answer:
The first and third.
Step-by-step explanation:
For the first one, you just subtract 52.37 and 46.37 and the answer is 6, so that makes the equation 6=y, which is right. The second one equals 6.75, so that's not what we need. For the third one, you divide by 8 on both sides to isolate y, and that results in y=6, which is right. For the fourth one you subtract by 3.2 on both sides to isolate y and that results in 5.8, which isn't what we need. I think for the last one you meant to type y=4+24, in which case that would be y=28, which isn't what we need.
The library at school is organized by fiction and non-fiction books. There are 3 non-fiction books for every 7 fiction books. How many total books are there if the library has 240 non-fiction books?
Answer:
Total = 800 books
Step-by-step explanation:
It is given that,
In a library, there are 3 non-fiction books for every 7 fiction books. It means that the ratio of non-fiction books to the fiction books is 3:7.
There if the library has 240 non-fiction books.
Let non fiction books are 3x and fiction books are 7x.
ATQ,
3x=240
x=80
Fiction books = 7x = 7(80) = 560
Total no of books = fiction books + non-fiction books
= 240 + 560
=800
Hence, the total no of books are 800.

A train travels at a speed of 58.6 km/h. Express this speed in
a. m/s
b. cm/min
Answer:
16.27778 m/s
97666.6667 cm/min
Step-by-step explanation:
a. To convert km/hr into m/sec, multiply the number by 5 and then divide it by 18.
m/s = (58.6 * 5) /18 = 16.27778 m/s
b. 1 Kilometer/Hour = 1666.66666666667 Centimeter/Minute
so 58.6 * 1666.666 =97666.6667 cm/min
The length of a rectangle is (3x-2) and its width is (2x+1). Find algebraic expressions to represent both the perimeter and area of this rectangle
Answer:
Perimeter = 10x-2
Area = 6x²-x-2
Step-by-step explanation:
Perimeter=2L+2W
2(3x-2)+2(2x+1)
6x-4+4x+2
10x-2
Area=LW
(3x-2)(2x+1)

Thomas wanted to measure the width of the pond so he set up triangles as shown in the diagram. He claims the two triangles are similar. How wide is the pond?
Answer:
156 ftStep-by-step explanation:
As per similarity, the ratios of corresponding sides are same:
x/120 = 65/50x = 120*65/50x = 156 ftAnswer:
Solution :-:Here we have to write ratio of corresponding ratio.
Let the side be x
[tex] \tt \dfrac{x}{120} = \dfrac{65}{50} [/tex]
[tex] \tt \: x = \dfrac{120 \times 65}{50} [/tex]
X = 156 ftThe measures of the angles of a triangle are shown in the figure below. Solve
for x.
Answer:
[tex]x = 46[/tex]
Step-by-step explanation:
Given
The three angles in the triangle are: x, 34 and 100
Required
Determine the value of x
Angles in a triangle add up to 180.
So, we have:
[tex]x + 34 + 100 = 180[/tex]
[tex]x + 134 = 180[/tex]
Subtract 134 from both sides
[tex]x + 134 - 134 = 180 - 134[/tex]
[tex]x = 180 - 134[/tex]
[tex]x = 46[/tex]
Hence, the measure of x is 46
sum of all angles in isosceles triangle is?
Answer:Every triangle has 180 degrees. An isosceles triangle has one vertex angle and two congruent base angles. Thus the vertex angle is 38 and the base angle is 71 and their sum is 109. :)

Can someone write the process and solution please?
Answer:
A
Step-by-step explanation:
We can get this by simplifying the inequalities
3(x-4) ≤ 18
3x - 12 ≤ 18
3x ≤ 18 + 12
3x ≤ 30
x ≤ 30/3
x ≤ 10
Secondly;
2(x-1) ≥ 6
2x - 2 ≥ 6
2x ≥ 6 + 2
2x ≥ 8
x ≥ 4
So the possible answer that fits both cases is 9
12 won’t work as it is not less than 10; we need an answer that is less than 10 to satisfy the first inequality
How do you make x the subject of the formula?
Step-by-step explanation:
Open the brackets
px - pq = x
Add pq to both sides.
px = x + pq
Subtract x from both sides.
px - x = pq
x (p - 1) = pq
Divide both sides by (p - 1)
x = pq/(p-1)

charles buys a pair of sneakers for 6.30. he wants to re-sell the pair of sneakers. he marks up the price by 40%. how much will he sell the pair of sneakers?
Answer:
Step-by-step explanation:
if Charles bought the sneakers for 6.30 and wants to re-sell them with 40% more,
first lets see how much is 40% of 6.30
(6.30*40)/100=2.52
he will resell the shoes with
6.30+2.52=8.82
Answer:
$[tex]8.82[/tex]
Step-by-step explanation:
[tex]6.30 + 0.4\times6.30 = 8.82[/tex]

If 9(1-x) = 27Y and x-y=-11/2, find the value of x + y.
Answer:
-2.25
Step-by-step explanation:
9(1-x) = 27Y
9-9x =27y
-9x -27y = -9 multiply all terms by -1
9x +27y =9 equation (1)
x-y= -11/2 equation (2)
by solving 2 equations
x= -3.875
y= 1.625
∴ x+ y = 1.625 +(-3.875) = -2.25

Use the scatter plot to fill in the missing coordinate of the ordered pair.
Answer:
(16, 6)
Step-by-step explanation:
The coordinate of an ordered pair is often represented as (x, y). That is, when x is equal to a particular value, the value of y would be the corresponding value to x on the coordinate plane.
So, given an incomplete ordered pair, (16, ), to find the missing coordinate, trace the value of y that corresponds to the value of x = 16.
That is, what is the value of y when x = 16.
From the plot, when x = 16, y = 6. The missing coordinate is 6.
Thus, we would have:
(16, 6).

Sovle for x help !!!!!!!!!
Answer:
C) 115 degrees
Step-by-step explanation:
A line is 180 degrees.
This means that the other side of the line with an angle of 115 degrees will be 180-115=65 degrees.
The angle above that will be 115 and the other will be 65.
Line v is similar to line u. This means that it is 115 degrees because the question mark is at the spot that is 115 degrees in the above angles.
Jada has 12 library books checked out and Han has 1/3 less than that. How many books does Han have checked out?
The total book checked out by Han will be equal to 8 which is 4 less than Jada.
What is an arithmetic operation?The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers. Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.
As per the given information in the question,
Total books checked out Jada = 12
Han has 1/3 less than Jada so,
12 × 1/3
= 4 books less than Jada.
So,
12 - 4 = 8 books checked out Han.

Step-by-step explanation:
7^-2 = 1/7^2
The negative means you flip it
1/7^2 times 7^6 is 7^6/7^2 (just multiply).
using rules of exponents, 7^6/7^2 is 7^4 (just subtract 2 from 6)
D is the only one that equals 7^4, as 2 times 2 is 4.

Step 2: Solve for x
Combine like terms: 6x + 3 = 6x + 3Subtract 3 on both sides: 6x = 6xDivide 6 on both sides: x = xHere we see that x does indeed equal to x.
∴ x = infinite amount of solutions.
2x + 3 + 4x = 6x + 3
Combine the like terms on the left side
2x + 4x = 6x
6x + 3= 6x + 3
Subtract 3 from each side
6x = 6x
Divide each side by 6
x = x
