Answer:
2. B
3. B
4. 2(7k+5h)
5. $325
Step-by-step explanation:
2) "X decreased by the sum of 2x + 5" Decreased means to be lowered, so that means this problem has subtraction in it. It also says x is being decreased BY the sum of 2x + 5 so that means 2x + 5 needs to be solved, which calls for parentheses. B best fits the description.
3) It is B because if you distribute the 8 to 2a and 3b, you'll get 16a and 24b, which is the given expression.
4) The given expression is 10h + 14k and in the equivalent expression, you are given 5h. To get from 10 to 5, you must divide by 2. This tells you that 2 is being distributed, so you put 2 before the parentheses. Since you divided 10 by 2, you want to do the same to 14, which is 7. Therefore, it is 2(7k+5h).
5) You are given the hourly charge, which is $25. This means that they charge $25 per hour/for every hour. You want to find the cost for 13 hours, so you multiply the hourly charge by 13 hours. 25 x 13 = 325.
Answer:
83
Step-by-step explanation:
Remember that the perimeter of a rectangle is two times the width plus two times the length. In other words:
2W + 2L = P
We know that the perimeter is 290 and the width is 62. We can plug these into the equation and solve for L.
2(62) + 2L = 290
124 + 2L = 290
Subtract 124 from both sides.
2L = 166
Divide both sides by 2.
L = 83
So now we know that the length is 83 feet.
