Answer:
1:1
Step-by-step explanation:
w = f, which means the amount of water equals the amount of flour.
Answer:
b = 6 mm
Step-by-step explanation:
Using Pythagoras' identity on the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 8² = 10²
b² + 64 = 100 ( subtract 64 from both sides )
b² = 36 ( take the square root of both sides )
b = 
= 6

By Substitution Method
<h2>
Step-by-step explanation:</h2>
Solve by Substitution :
We have two equations
y = 5x ---------------> Equation 1
y = 2x - 15 ------------> Equation 2
y= 2x - 15 and y= 5x
So Put the value of y in Equ 2
(5x) - 2x = -15
3x = -15
Solve equation [1] for the variable x
3x = - 15
x = - 5
Now
y = 5x
x = -5
Use the x value to solve for y
y = 5(-5) = -25
Solution :
{y,x} = {-25,-5}
So y= -25 and x= -5
Just find the GCF of the numerator and the denominator after multiplying across.
