P=80 <---this is the answer
Unsure of what y ou want! y = 4x + 5 is already in slope-intercept form. If you want "standard form," which looks like Ax + By + C = 0, then identify A, B and C from the given equation y=4x+5. Rewrite this as -4x + 1y - 5 = 0, so that A=-4, B=1 and C= -5. This is the eqn in standard form.
Answer:
34
Step-by-step explanation:
All angles of a triangle add up to 180 degrees so you would subtract from 180 with the angles you already have to get your answer. 180 - 115 - 31 = B which is 34.
The answer is $2.7 per gallon
Answer:
A. 12 grams Zn
B. 280 g of copper.
Step-by-step explanation:
100 grams of brass
20 grams of zinc
100 grams of brass has 20 grams of Zn.
20/100 = 0.200 Zn <u>20% Zn and 80% copper</u>.
A. (60 g brass)*(0.2) = 12 grams Zn
B. (350 g brass)*(0.80) = 280 g of copper.
