Answer:
R = 25
Step-by-step explanation:
Given
- 6 = - 1
Multiply through by 5 to clear the fraction
R - 30 = - 5 ( add 30 to both sides )
R = 25
K + (-4.1) is the exact same as saying k- 4.1, so what you have to do now is put the -4.1 in the opposite side, but with opposite sign too (+)
so k= -9.7 + 4.1
so in order to answer it you have to deduct the number with the lowest value taking in count both as positive and the sign will be the one from the highest value taking both as positive
9.7
-4.1
____
5.6
so 9.7 had a negative sign so the answer to your question is
k = -5.6
i hope i helped you
Answer:
x = -1
Step-by-step explanation:
since the 23 is positive you have to subtract it on both sides . which would give you -4x =4
then divide -4 on each side and you should get x = -1
a positive divided by a negative is always negative.
The figures are similar.
the side that is 16 on A is similar to the side that measures 4 on figure B
24 is similar to 6
32 is similar to 8
24 is 4 times 6
24 / 6 = 4
32 is 4 times 8
32 / 4 = 4
and 16 is 4 times 4
16 /4 =4
Figure A is 4 times bigger than Figure B. That is your scale factor.
