the sum of two numbers is 55 and the difference is 9. what are the numbers?
Answers
x - y= 9
y = 23
x = 32
the numbers are 23 and 32
From the second equation x=9+y (substitute that into the first equation to solve for y).
9+y+y=55
2y=46
y=23. (Substitute that back into the second equation to find x.)
x=9+y = 23+9 = 32.
23+32 = 55 (Check).

Which expression shows the distance on the number line between −7 and 16?
a) |−16−(−7)|
b) |−7+16|
c) |7−16|
d) |−7−16|
Answers
Final answer:
The correct expression to find the distance on the number line between -7 and 16 is |16 - (-7)|, which equals 23 units. The distance is always a positive number.
Explanation:
The expression that shows the distance on the number line between −7 and 16 is |16 - (-7)|.
To find the distance between two points on a number line, subtract one point from another and take the absolute value of the result. This ensures the distance is positive, as distance cannot be negative. Hence, the correct expression is:
|16 - (-7)| = |16 + 7| = |23| = 23
So, the distance between the points is 23 units.

You want to isolate h by itself, so subtract both sides by 9.
h/4 = -3
Then, get rid of the denominator, 4, by multiplying both sides by 4 (nit a fraction but as awhole number)
h = -12
2) Apply the same concept to this problem.
m/-3 + (-2) = 11
Distribute the sign over the parenthesis.
m/-3 - 2 = 11
Add 2 to both sides.
m/-3 = 13
To get rid of the denominator, multiply both sides by -3
m = -39
3) r/-5 - (-6) = 10
r/-5 + 6 = 10

z/-4 = -7
z = 28

a group of hikers climbed from salt flats (elevation-55.03 ft) to talon bluff (elevation 620.75 ft). what is the difference between talon bluff and salt flats?
Answers
To calculate the elevation difference between Talon Bluff and Salt Flats, you subtract the elevation of Salt Flats from the elevation of Talon Bluff, resulting in a total ascent of 675.78 feet
The question asks about the elevation difference between two points, Salt Flats and Talon Bluff. To find the difference in elevation, you simply subtract the elevation of Salt Flats from the elevation of Talon Bluff. Therefore, the difference is
Elevation of Talon Bluff - Elevation of Salt Flats = 620.75 ft - (-55.03 ft) = 675.78 ft.
This means that the hikers ascended a total of 675.78 feet in elevation from the Salt Flats to Talon Bluff

Here,
A regular quadrilateral is a square.
the perimeter of the rectangle = 4 × side
12 = 4 × side
side = 12 / 4
Side = 3 inch
Area of the square = side²
Area of the square = 3²
Area of the square = 9 square inches

Andrei has a glass tank. First, he wants to put in some marbles, each of which has a volume of 0.4 liters. Then, he wants to fill the tank with water until it's completely full. If he uses 50 marbles, he will have to add 33 liters of water.
What is the volume of the tank?
Andrei has exactly 20 liters of water. How many marbles does he need so the tank is full?
Answers
35 litters because
0.04*50 is 2
2+33 is 35
The volume of Andrei's tank is 53 liters. To fill the tank with 20 liters of water, Andrei needs 82 marbles, as marbles and water together must reach the tank's total volume.
Explanation:To find the volume of the glass tank that Andrei has, we need to calculate the total volume of marbles and water that fills the tank. Since each marble has a volume of 0.4 liters and he uses 50 marbles, the total volume of the marbles is:
0.4 liters/marble × 50 marbles = 20 litersWith 33 liters of water needed to fill the tank after the marbles are added, the total volume of the tank is:
20 liters (marbles) + 33 liters (water) = 53 litersTo determine how many marbles Andrei can add if he has exactly 20 liters of water, we set up the equation with the unknown number of marbles (represented by 'x'):
0.4 liters/marble × x marbles + 20 liters (water) = 53 liters (total volume)From the equation, we solve for x:
0.4x + 20 = 530.4x = 33x = 33 / 0.4x = 82.5 marblesSince Andrei cannot use a fraction of a marble, he'll need to use 82 marbles to fill the tank with 20 liters of water.

Answers
hope this helps if so please mark me brianliest
Answer:
[tex]\frac{9}{8}[/tex] feet per hour fast is Kelly's knitting speed
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity 1 such as 4 meter per seconds or 4 miles per hour.
As per the statement:
Kelly is knitting a scarf for her brother. it took her 1/3 hour to knit 3/8 foot of the scarf.
She took /3 hour to knit 3/8 foot of the scarf.
Then by definition of unit rate we have;
[tex]\text{Unit rate per hour} = \frac{\frac{3}{8} }{\frac{1}{3} } =\frac{3}{8} \cdot 3 = \frac{9}{8}[/tex] feet
Therefore, [tex]\frac{9}{8}[/tex] feet per hour fast is Kelly's knitting speed.

Answers
total . 96
Sandra and Teo will have a total of 96 items for the bake sale. We find this by first multiplying the number of trays Sandra baked by the number of cookies per tray, then multiplying the number of Teo's brownie pans by the pieces per pan, and finally adding our two results together.
Explanation:The subject of the question is Mathematics, specifically it is an arithmetic problem involving multiplication and addition. It is a middle school grade level question.
To solve it, we need to multiply the number of trays Sandra baked by the number of cookies on each tray. So, 4 (trays) * 12 (cookies) = 48 cookies.
Next, multiply the number of brownie pans Teo baked by the number of pieces each pan was divided into. That is, 6 (pans) * 8 (pieces) = 48 brownies.
Finally, to find the total number of items for the bake sale, we simply add our two results: 48 (cookies) + 48 (brownies) = 96 items.
