Answer:
2t blocks
Step-by-step explanation:
We measure these distances from Jim's house.
The school is t blocks from Jim's house. Twice that is 2t blocks. Thus, the library is 2t blocks from Jim's house.
An inverse operation reverses the effect of another operation. Answer is C
72 people. Multiply 8 times one and a half, and then by six.
Answer:
2 ( m + 2 m) = 36 is the required linear equation
Length of the rectangle is 12 ft and width = 6 ft
Step-by-step explanation:
Let the width of the rectangle = m ft.
So, the length of the rectangle = 2m ft.
Perimeter of rectangle = 36 ft
Now, PERIMETER OF THE RECTANGLE = 2(LENGTH + WIDTH)
⇒2 ( m + 2m) = 36
or, 2 x 3m = 36
⇒ 6m = 36 , or m = 36/6
⇒ m =6 ft
So, the Width of the rectangle; = m = 6 ft
and the Length of the rectangle = 2 m = 2 x 6 = 12 ft.
Answer:
While x = -7 and y = 4, x² - 3xy = 133.
Step-by-step explanation:
x² - 3xy
Substitute variables.
(-7)² - 3(-7)(4)
Square -7 remembering that (-x)² = x².
49 - 3(-7)(4)
Multiply -7 and 4.
49 - 3(-28)
Multiply -3 and -28.
49 + 84
Add 49 and 84.
133
