Answer:
2.5 cm
Step-by-step explanation:
Rectangle A L x W = 40
Rectangle B L * W = 1/2 (40)
8 * W = 20
W = 2.5 cm
Answer:
The width of B. is 2.5cm
Step-by-step explanation:
Rectangle A has 40cm^2 and a length of 8.
Rectangle B. has an area half of 40cm^2 which would be 20cm^2.
Area of B has an area of 20cm^2
Now we need to find the width of B.
All that we know is that B. has an area of 20cm and it has the same length as A, and that length is 8.
Everyone knows that you multiply the length by the width to find the area of a shape.
8 times something = 20
We can do that backward and divide 8 by 20 which is 2.5
To check this answer we multiply 2.5 by 8 which = 20
The width of rectangle B. is 2.5cm.
I hope that this helps! -Karen

How I divide by negative?? I forgot completely
Answers
Answer:
I hope this helps. If I misunderstood the question let me know
Step-by-step explanation:
1. When dividing a negative by a negative, your answer would be positive.
2. When dividing a negative by a positive, your answer will be negative.
3. When dividing a positive by a negative,your answer will be negative.
Divide like you normally would, the result will be the same as positive-number-quotients, but the quotient will be negative.
Example:
10 ÷ -5
since 5 is the dividend, 5 goes into 10 two times but note that it's negative two because of the negative division logic.

Answer:
I only know the first 1 sorry but here is the answer y=-3/4+2
Step-by-step explanation:
3x+4y=8
-3x -3x subtract -3x to get on the right side
4y=-3x+8
/4 /4 /4 divide by 4 on both sides
y=-3/4x+2 since 4 can't go into 3 you leave as a fraction -3/4x
UPDATE: I found the answer to number 4
The answer is y=-11/7x+8
-11x-7y=-56
+11x +11x Add 11x
-7y=11x-56
/-7 /-7 /-7 Divide by -7 on both sides
y=-11/7x+8 Since -7 can't go into 11 you leave as a fraction -11/7x
ANOTHER UPDATE: I found the answer to number 7
-14x+y=7
+14x +14x Add 14x to both sides
y=14x+7 Since y doesn't have a number your answer is as shown
