Given:
Cost of two donuts and three cookies = $3.30
Cost of five donuts and two cookies = $4.95
To find:
The cost of each donut.
Solution:
Let x be the cost of each donut and y be the cost of each cookie.
Cost of two donuts and three cookies = $3.30
...(i)
Cost of five donuts and two cookies = $4.95
...(ii)
Multiply equation (i) by 2.
...(iii)
Multiply equation (ii) by 3.
...(iv)
Subtracting (iii) from (iv), we get
Divide both sides by 11.
Therefore, the cost of each donut is $0.75.
The point-slope form of the equation for a line through point (h, k) with slope m is ...
y - k = m(x - h)
For your given point and slope, this equation is
y + 1 = -1(x + 10)
Since the total weight would be equal to the weight of the firefighter added to the weight of the equipment, the total weight would be x+60. So the answer is B. t=x+60
Hope this helps
Answer:
a slope is a number that describes both the direction and the steepness of the line.
Step-by-step explanation:
Since 7 - p are in the parenthesis and 5 is outside the parenthesis u distribute 5 to 7 and -p. 5 x 7 is 35 and 5 x -p is -5p so ur answer is A, -5p + 35.
