27) 3 (-5) (-7)
When there is no math symbol between numbers it is multiplication.
Multiply from left to right:
3 * -5 = -15
-15 * -7 = 105
28) -2 * 2 (-3) *2 =
-2 *2 = -4
-4 * -3 = 12
12*2 = 24
31) A negative divided by a negative is positive:
-128 / -4 = 32
32 -36 / 2 / 24 /4
Divide the top and bottom first then divide those:
-36 / 2 = -18
24 / 4 = 6
-18 / 6 = -3
Answer:
x = 5
Step-by-step explanation:
(3-6x)/3 = -11
first multiple both sides by 3
3 - 6x = -33
then subtract 3 from both sides
-6x = -30
then divide by 6
x = 5
The answer is c
Because if it takes 50 minutes to run 4 miles you need to divide 50/4 and you will get 12.5 and then multiply that by 30 cause she is trying to run 30 miles and that will get you 375 and then divide that by 60 cause their are 60 minutes in a hour and you will get 6.25
Answer:
d.
Step-by-step explanation:
Since it's an isosceles triangle, WX=WZ= 2n-5
Perimeter = n + (2n-5) + (2n-5)
= 5n - 10
The Perimeter is given to be 20
5n - 10 = 20
5n = 30
n = 6
10.…….……......................
