Answer:
Step by step explanation: OK so your question is 26.35×21.5 so that is pretty easy but if you do not know that you are in the right place so what you’re gonna do is if you have a calculator then you need to take that out if you don’t then I’m going to need a piece of paper now for me it’s easy because I have a calculator and you can find a calculator on your iPad your phone etc. but yeah so you’re gonna type in 26.35 Times 21.5 now I want u do that on your own once you type in those numbers you’re going to hit the = and it’s that simple and you’ll then get your answer so I hope that helped you to learn how you multiply those the numbers.

Answer:
(7, - 1 )
Step-by-step explanation:
Given the 2 equations
2x + 4y = 10 → (1)
- 2x + y = - 15 → (2)
Adding the 2 equations term by term eliminates the term in x, that is
5y = - 5 ( divide both sides by 5 )
y = - 1
Substitute y = - 1 into either of the 2 equations and solve for x
Substituting into (1)
2x + 4(- 1) = 10
2x - 4 = 10 ( add 4 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7
Solution is (7, - 1 )
The dimension of the parallelogram is length = 25 m and width = 15 m.
What is a parallelogram?
A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side. 360 degrees is the sum of all interior angles.
The perimeter of a parallelogram is 2(length + breath).
Let the breath of the parallelogram be x.
Given that the length of the parallelogram is 10 m longer than width.
The length of the parallelogram is (x + 10)m
The perimeter of the parallelogram is 2(x+10 +x) = 2( 2x + 10)
According to the question,
2(2x + 10) =80
Divide both sides by 2
2x + 10 = 40
Subtract 10 from both sides:
2x = 30
Divide both sides by 2
x = 15
The length of the parallelogram is (10 + 15) m = 25m.
