Answer:
9, 7,-8.3,>
Step-by-step explanation:
5)-3 is marked exactly 3 units to the left of origin 0.
(since negative sign we mark on left of 0)
6) |-9| = absolute value of 9 = 9
7) y-11=-4
Add 11 to both the sides
WE get y =7 is the solution
8) a + b when a = 2.5 and b = -10.8.
= 2.5+(-10.8) = -(10.8-2.5) = -8.3
9) 0.4 is positive hence lies to the right of origin.
Partition the space between 0 and 1 into 10 equal subparts and mark 4th subdivision to get 0.4
10) -1.8>-2.5
Answer:
A) 56 . . . . . . the (negative) sum of -7 and -49
b) 112 . . . . . the product of 7 and 16
c) 16 . . . . . . the square of 8/2
The length would be 10 inches.
to find perimeter, you add length+length+width+width.
since both widths and both lengths have to be the same, u add the width 2 times or 7+7=14.
next u subtract 14 from 34 or 34-14=20.
since u still have 2 lengths that are equal, u divide 20 by 2 or 20/2=10
hope this helps! :)
Answer: No. When 1 is substituted for the variable, the result is a false statement
Step-by-step explanation:
3x - 6(5x + 5) = 9x + 6
3x - 30x - 30 = 9x + 6
-27x -30 = 9x +6
-27x - 9x = 30 +6
-36x = 36
x = -1.
Substitute with x = -1 :
-3 - 6(-5 + 5) = -9 +6
-3 -30 + 30 = -3
-3 = -3
Therefore, the correct option is:
No. When 1 is substituted for the variable, the result is a false statement
Answer:
a. 11
Step-by-step explanation:
triangle lmn is twice triangle abc
2(x+4)=3x-1
2x+8=3x-1
x=7
7+4=11
