Draw a diagram to illustrate the problem.
Let n = number of strips required.
Note that 10 feet = 10*12 = 120 inches.
Because each strip is 20 inches wide, therefore
20n = 120
n = 120/20 = 6
Answer: 6 strips
Answer:
$8.2
Step-by-step explanation:
The final price of the coat = $45 -0.2 * $45 = $36
The final price of the suit = $95 − 0.3 * $95 = $66.5
sarosh's commission = 0.08 * ( $36 + $66 ) = $8.2
All triangles have a measurement of 180 degrees. Therefore, we can use this information to make an equation to find the value of angle B.
Angle B = 180 - (28 + 36)
Angle B = 180 - 64
Angle B = 116
So, angle B is equal to 116 degrees.
Answer:
Step-by-step explanation:
Declaration
Let Brand A number of 2.00 socks= x
Let Brand B number of 3.00 socks = y
Equations
Number of socks : x + y = 5
Cost of socks: 2x + 3y = 13
Solution
Multiply top equation by 2
2(x+ y = 5)
2x + 2y = 10
Write the new equation under the cost of socks equation
2x + 3y = 13
<u>2x + 2y = 10</u> Subtract.
y = 3
She spent 3 dollars on 1 pair of socks.
Now she needs to calculate the number of 2.00 dollar socks
2x + 3y = 13
2x + 3*3 = 13 Combine the left
2x + 9 = 13 Subtract 9 from both sides.
2x +9-9 = 13-9 Combine
2x = 4 Divide by 2
2x/2 = 4/2
x = 2
Answer
#2 dollar socks = 2
#3 dollar socks = 3
