Given:
25.83 - part
52.5% percentage of the part against the whole
To get the whole number, we need to divide the part by its corresponding percentage.
25.83 ÷ 52.50% = 49.20
49.20 is the whole number wherein 25.83 represents 52.50% of it.
C. we multiply the equation by 3
Answer:
No solution.
Step-by-step explanation:
−3> 7x−8 > −0.2
Split this into 2 inequalities:
7x - 8 < -3 Add 8 to both side:
7x < 5
x < 5/7.
and:
7x - 8 > -2 Add 8 to both sides:
7x > 6
x > 6/7.
But x cannot be both less than 5.7 and > 6.7, so No solution.
Let C be the amount of compost
T be the amount of topsoil
Each compost cost = $25
Cost of C compost = 25C
Each topsoil cost = $15
Cost of T topsoil = 15T
Amount of compost + amount of topsoil = 10
C + T = 10 -------> Equation 1
cost of C compost + cost of T topsoil = 180
25C + 15T = 180 --------> equation 2
Solve the first equation for C
C + T = 10
C = 10 - T
Now plug it in second equation
25C + 15T = 180
25 ( 10 - T) +15T = 180
250 - 25T + 15T = 180 (combine like terms)
250 - 10 T = 180 (Subtract 250 on both sides)
-10T = 180 - 250
-10T = -70 ( divide by -10 on both sides)
T = 7
She purchased 7 cubic yards of topsoil .
Neither. When graphing both lines they intersect but are not perpendicular.
