So if the ratio is 4:5, we know that this total amount of marbles must first be split into 9 equal parts:
Now we know that each 'part' is going to be equal to 7 marbles.
So then in the ratio, we are simply going to multiply each side by 7:
Therefore, since John had the part of '5' in the ratio, the amount of marbles that John got was 35.
Answer:
<em>x=8</em>
Step-by-step explanation:
<u>Triangles</u>
An isosceles triangle is a triangle with two equal sides. The angles the equal sides form with the third side are also equal.
The triangle shown in the figure is isosceles and the angles marked as '2' and 67° are equal. But we are also given that the angle '2' equals 8x+3, thus:
8x+3=67
Reducing:
8x=67-3=64
Solving:
x=64/8
x=8
Answer:
x = 11
x = 10.7
x = 40
Step-by-step explanation:
Choose any number that is greater than 10.5.
The solutions are what x can equal to.
Keep the solutions in decimal form.
x = 11
x = 10.7
x = 40
All of these numbers are greater than 10.5.
