Answers
Answer:
1/5
Step-by-step explanation:
b and c = [tex]\sqrt{50}[/tex] because 10 x 5 = 50
therefore the fraction is √2/ √50
to simplify you need to simplify the √50 into a number of √2 as the top is √2
√50 = √25 x √2
= 5√2
√2/5√2 = 1/5 if you divide both top and bottom by √2

x=1
Square root of 1 is 1
Answer:
√5x+1 = 6
(√5x+1)2 = (6)2
5x+1 = 36
5x -35 = 0
Add 35 to both sides
5x = 35
Divide both sides by 5

Write an equation to represent 'twice a number (x) is fifty"
Answers
Answer:
2x=50
Step-by-step explanation:
Hi there,
Your question is "twice a number (x) is fifty"
Recall how a number is represented by x.
Twice a number would be represented as 2x.
Therefore, to represent that twice a number is equal to 50, that would result in the expression: [tex]2x=50[/tex]
If you're looking to solve this equation, it's often best to think about the "reverse" of the current equation.
Notice how 2 is multiplying the x.
To isolate x, divide that side by 2.
However, recall that whatever is done to one side of an equation must also be done to the other side of the equation. Therefore, you will need to divide both sides by 2.
[tex]2x=50[/tex]
[tex]\frac{2x}{2} = \frac{50}{2}[/tex]
[tex]x=25[/tex]
Equation: [tex]2x=50[/tex]
Solving for x: 25
Hope that helps!

How many pieces of ribbon can you cut from 10 meters, if each piece is 4
cm long?
Answers
Answer:
answer:250 pieces
1 metre=100cm so
10metres =100*10 =1000cm
each piece is 4 CM long, so.,
no. of pieces=1000/4
by dividing by 2....
=500/4
again by dividing by2...
=250/1=250 pieces
so 250 pieces of ribbon can be cuttted from 10 metre long ribbon.
each of equal sides of an isosceles triangle is 4cm greater than its height .If the base of triangle is 24 cm ,calculate the perimeter and the area of the triangle
Answers
192 cm²
Step by step explanation :-Let us take the height be x , then its side = x + 4. Now half of base will be 12 cm .
According to Pythagoras Theorem :-
=> base² + perpendicular ² = hypontenuse ²
=> 12² + x² = (x+4)²
=> 144 + x² = x² + 16 + 8x
=> 8x = 144-16
=> 8x = 128
=> x = 128/8
=> x = 16 cm .
Hence the height of ∆ is 16 cm .So the area will be half the product of base and altitude.
= 1/2 * 16 cm * 24cm .
= 192 cm²
★ Hence the area of the triangle is 192 cm² .scrap metal buyer pays $3.18 Per square foot of steel. how much can you earn by selling the steel drum below? round your answer to the nearest dollar.

If x is Mary's age now and yis John's age now, which system of equations could not be used to solve the problem?
Answers
Answer:
M=15
J=20
Step-by-step explanation:
Let J and M be the present age of John and Mary respectively:
J=M+5
2(J+10)−(M+10)=35
2(M+5+10)−(M+10)=35
2M+30−M−10=35
M=15
J=20
