Answer:
87 minutes
Step-by-step explanation:
Let the total number of minutes = m
Our equation is given as:
$20.21 = $14.99 + 0.06m
20.21 = 14.99 + 0.06m
Collect like terms
0.06m= 20.21 - 14.99
0.06m = 5.22
m = 5.22/0.06
m = 87
Therefore, the total number rod minutes used is 87 minutes
Answer:
2x-3 = 29
8x = 128
x+7 = 23
Step-by-step explanation:
The sum of the angles of a triangle is 180
2x-3 + 8x+ x+7 = 180
Combine like terms
11x+4 = 180
Subtract 4 from each side
11x+4-4= 180-4
11x = 176
Divide by 11
11x/11 =176/11
x =16
2x-3 = 2*16-3 =32-3 = 29
8x = 8*16 =128
x+7 = 16+7 = 23
Answer:
4.2 is: 1.) between 4 and 5 closer to 4
7/8 is: 3.) between 0 and 1 closer to 1
-9/5 is: 2.) between -1 and -2, closer to -2
Answer:
25 pounds of nuts and 5 pounds of cereal squares.
Step-by-step explanation:
Let amount of nuts be x and cereals squares be y pounds.
x + y = 30
7x + 4y = 30*6.5
7x + 4y = 195 Multiply the first equation by -4:
-4x - 4y = -120 Adding:
3x = 75
x = 25 pounds.
y = 30 - 25 = 5 pounds.
