Answer:
![50\%](https://tex.z-dn.net/?f=50%5C%25)
Step-by-step explanation:
To Calculate the percentage Increase
<u>Step 1</u>: Subtract the old value from the new value
1.8 mg - 1.2 mg = 0.6 mg
<u>Step 2:</u> Divide the difference by the Old Value
![\dfrac{0.6}{1.2}](https://tex.z-dn.net/?f=%5Cdfrac%7B0.6%7D%7B1.2%7D)
<u>Step 3: </u>Multiply by 100
![\dfrac{0.6}{1.2} X 100\\=50\%](https://tex.z-dn.net/?f=%5Cdfrac%7B0.6%7D%7B1.2%7D%20X%20100%5C%5C%3D50%5C%25)
The Percentage Increase in Iron is 50%.
Answer:
4 pizzas - 26 cups
13 cups - 2 pizzas
Step-by-step explanation:
4 pizzas:
39 cups : 6 pizzas
6.5 cups : 1 pizza
6.5×4 cups : 4 pizzas
4 pizzas = 26 cups
6.5 cups : 1 pizza
13/6.5 cups : x pizzas
13 cups = 2 pizzas
Answer:
3x + y = 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
3x + y = - 12 ( subtract 3x from both sides )
y = - 3x - 12 ← in slope- intercept form
with slope m = - 3
• Parallel lines have equal slopes , then
y = - 3x + c ← is the partial equation
to find c substitute (- 1, 5 ) into the partial equation
5 = 3 + c ⇒ c = 5 - 3 = 2
y = - 3x + 2 ← equation in slope- intercept form
add 3x to both sides )
3x + y = 2 ← equation in standard form
