Step-by-step explanation:
l = length
w = width
l = 3w
perimeter p = 2l + 2w = 56
using the identity of the first equation
p = 2(3w) + 2w = 56
6w + 2w = 56
8w = 56
w = 7 cm
l = 3w = 3×7 = 21 cm
so, the area is
l×w = 21×7 = 147 cm²
Step-by-step explanation:
(-7)+(-6)+(-1)=-14
(-14)-3=-11
-11÷7=-1.5714285714286 or -2 if you round too the tenths place
Answer/Step-by-step explanation:
1. -14
2. 3
3. -3
4. 10
5. -8
1. 4 x -3 = -12 - 2 = 14
2. -3 x 2 = -6 + 9 = 3
3. 8 divided by 4 = 2 - 5 = -3
4. 3/2 = 1.5 x 2 = 3 + 7 = 10
5. -9/3 = -3 - 5 = -8
Answer:
c.
Step-by-step explanation:
Ralph’s calculation is correct, he will have to pay $9,280 in federal taxes this year.
The answer is the sum of three times a number and six, divided by the difference of seven times a number and nine.
The phrase is(3p+6)/(7p-9)
Let’s describe each factor:
3p is three times a number
7p is seven times a number
3p+6 is the sum of three times a number and six
7p-9 is the difference of seven times the number and nine
The last two factors are divided, so
(3p+6)/(7p-9) is the sum of three times a number and six, divided by the difference of seven times the number and nine.
I hope this helped and have a nice day!
