Answer:
Step-by-step explanation:
im guessing this is a system of equations so:
-7-y=13
8x+y=-14
so you can cancel them, out by adding
after you do the math you should get x=-1
substitute for y and you get y=-6

For a suitcase to be checked on a flight (instead of carried by hand), it can weigh at most 50 pounds. Andre’s suitcase weighs 23 kilograms. Can Andre check his suitcase? Explain or show your reasoning. (Note: 10 kilograms ≈≈ 22 pounds)
Answer:
No, I don't think so.
Step-by-step explanation:
If his suitcase weighs 23 kg and 10 kg is 22 pounds. You could seperate it. 10, 10, and 3 meaning 22+22= 44. This would mean that 1 kg would equal about 2.2 a pound. So 44 + ( 2.2 x 3 ) = 50.6 kg.
It would be 0.6 k.g over. I think this is right unless I calculated this wrong.
Andrew can not check his suitcase and it needs to remove some items or repack it in order to reduce the weight.
What are Units ?To measure and compare various things we use one term which is known as a unit.
For example, for length measurement we use units like:- metre, centimetre, inch, miles.
To determine if Andre can check his suitcase, we need to convert the weight of his suitcase from kilograms to pounds since the weight limit for checked luggage is given in pounds.
Given that 10 kilograms ≈ 22 pounds, we can convert Andre's suitcase weight of 23 kilograms to pounds by multiplying it by the conversion factor:
23 kilograms x 22 pounds/kilogram ≈ 506 pounds
Therefore, Andre's suitcase weighs approximately 50.6 pounds, which exceeds the weight limit of 50 pounds.
Therefore, Andre cannot check his suitcase and needs to remove some items or repack it to reduce the weight below the weight limit.

Which is the solution to the system of equations?2x+y=7 and 3x−4y=5
Answer:
X = 3, Y = 1.
Step-by-step explanation:
X = 3 and Y = 1, because 2 times 3 equals 6, and 6 plus 1 equals 7. So that's for the first one, but now we need to make sure that it's the same value for the other equation. 3 times 3 equals 9, 4 times 1 equals 4, and 9 minus 4 equals 5. So X = 3, and Y = 1. Hope this helped :D

Write a polynomial that represents the perimeter of the figure
Answer:
4x² + 4x + 8
Step-by-step explanation:
P = 2( 2x² - 3x + 1 ) + 2( 5x + 3 ) = 4x² - 6x + 2 + 10x + 6 = 4x² + 4x + 8
4x² + 4x + 8
Answer:
4x^2 + 4x + 8.
Step-by-step explanation:
Perimeter = 2(width + length)
= 2(5x + 3 + 2x^2 - 3x + 1)
= 2(2x^2 + 2x + 4
= 4x^2 + 4x + 8.

Step-by-step explanation:
Because 25+38=63 and 63/7 is equal to 9.
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The value of c in the expression (c + 38) / 7 = 9 is 25.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
(3x + 2)/ 3 is an expression.
2x + x + 4x is an expression.
We have,
(c + 38) / 7 = 9______(1)
We will solve for c.
From (1).
(c + 38) / 7 = 9
Multiply 7 on both sides.
7 x (c + 38) / 7 = 7 x 9
c + 38 = 63
Subtract 38 on both sides.
c + 38 - 38 = 63 - 38
c = 25
Thus,
The value of c in the expression (c + 38) / 7 = 9 is 25.

Step-by-step explanation:
You're looking for the hypotenuse of a right triangle, so you'll use the pythagorean theorem of a^2 + b^2 = c^2. And here, you're looking for c^2
(18)(18) + (36)(36) = c^2
324 + 1296 = c^2

What is the surface area of the cone in terms of π?
A cone. The diameter of the base is 8 meters and the slant height of the cone is 15 meters.
Answer:
The surface area of the cone is;
68 π m^2
Step-by-step explanation:
Here, we want to get the surface area of the cone
Mathematically, we have this as ;
S.A = π(r^2 + rl)
where r is the radius and l is the slant height
We are given the diameter, but the radius is half of this
d = 8
r = d/2 = 8/2 = 4 m
l = 13 m
S.A = π(4^2 + 4(13))
= π(16 + 52) = 68 π m^2
Answer the question to get marked as barinliest!!!!!
Answer:
The answer is option B.
A = pi • 8^2
Step-by-step explanation:
The formula for area of a circle as A = pi • r^2. Radius is half the diameter, and the given diameter is 16 - therefore, the radius is 8. You then have to raise it to the second power and multiply it by pi to get the area of the circle. Hope this helped! Best of luck.

Step-by-step explanation:
To convey the ideology and retort proposed, the imminent is evaluated.
- To commence, the beginning of the interrogate states the figure obtains a diameter configuration of 16 inches.
- In addition, the radius, given which the diameter is equivalent to such, is obligated to equal 8 inches (r = 1/2(d)).
Furthermore, the precedent may be equated as the following:
A=πr^2
A= π * 8^2, whom is expressed to the unit of A = π * 64
Alas, in conclusion, the voracious retort, subject to the interrogate is equivalent to A = π * 8^2, A = π * 64, or "B."

The circumference of a circular garden is 119.32 feet. What is the radius of the garden? Use 3.14 for t and do not round your answer.
Answer:
r = 19 ft
Step-by-step explanation:
Circumference, C is given as 119.32 ft
Circumference of a circle is given by the formula, 2πr
This means that,
C = 2πr, we're told to assume that π = 3.14
So therefore,
119.32 = 2 * 3.14 * r
r = 119.32 / 6.28
r = 19 ft
