Answer:
The first rate was 120
The second rate was 85
Step-by-step explanation:
r1 = x
r2 = y
10*x + 15*y = 2650
x + y = 205 Multiply this equation by 10
10x + 10y = 2050 Subtract this equation from the top equation.
10x + 15y = 2650
10x + 10y = 2050
5y = 600
y = 600/5
y = 120
x + y = 205
x + 120 = 205
x = 205 - 120
x = 85
Answer:
1/2
Step-by-step explanation:
There are 25 odd numbers between 1 and 50.There are total of 50 numbers. Probability is 25/50.
Its A
7x+7= 112
7x= 112-7
7x=105
x=105/7
x=15
To find y
180-112=68
68/4 =17
x= 15 y=17

Answer:
The answer to your question is Area = 3240 ft² or Area = 360 yd²
Step-by-step explanation:
Data
length = 30 yd
width = 36 ft
Area = ? ft²
Area = ? yd²
Process
1.- Convert the units
1 yd --------------------- 3ft
30 yd ------------------ x
x = (30 x 3)/1
x = 90 ft
1 yd ------------------- 3 ft
x ------------------- 36 ft
x = (36 x 1) / 3
x = 12 yd
2.- Calculate the area of the rectangle in ft²
Area = length x width
-Substitution
Area = 90 x 36
= 3240 ft²
3.- Calculate the area in yd²
Area = 30 x 12
= 360 yd²
