Answer: 10
Step-by-step explanation:
These types of questions involve ratios. So 2.5: 25 is equal to 25 : 250 and all i did was multiply both sides by 10. Then it says that he only has 1 pound of ground beef so 25* 1/25 is equal to one, and then 250 * 1/25 is equal to 10.
Answer: x = 3
Step-by-step explanation: First, isolate the x term by adding 4 to
both sides of the equation. We get 2/3x = 2.
Next, multiply both sides of the equation by the
reciprocal of 2/3 which is 3/2 to get x by itself.
So we have (3/2) 2/3x = 2 (3/2).
On the left, (3/2) 2/3 cancels and we have x.
On the right, the 2's cancel and we have 3.
So x = 3 is our answer.
The dimensions she would take are length = 24cm and width = 7cm
<h3>What is a rectangle?</h3>
A rectangle is a polygon with 4 sides and 4 right angles.
Analysis:
let the width be = x
Length = 2x + 10
Diagonal = 25
The diagonal, length and width of the rectangle form a right angle triangle and by Pythagoras,
= +
625 = + 4 + 40x + 100
5 + 40x +100 - 625 = 0
5 + 40x - 525 = 0
divide through by 5
+ 8x - 105 = 0
+15x - 7x - 105
x(x + 15) -7(x + 15) = 0
(x-7)(x+15) = 0
since dimension cannot be negative x = 7
so width is 7cm
Length = 2x+ 10 = 2(7) + 10 = 24cm
In conclusion, the dimensions are 24cm and 7cm.

Answer:
y = 6x + 1
Step-by-step explanation:
Use the point slope equation:
y - y1 = m( x - x1 )
y - 1 = 6 ( x - 0)
y - 1 = 6x
y = 6x + 1
