Answer:
answer is -8.9*1.4 = -12.46
(the new amount-the original amount)÷the original amount=the percent of change
(x-25)/25=300%=3
x-25=75
x=100
Answer:
D) -8
Step-by-step explanation:
If you add a positive and a negative, you end up subtracting. If your sum is lower than any of the numbers you are adding together, then there is a negative. In this case, your only negative number is -8, but if there were others, you could find this equation by doing negative six minus two (because the equation was originally addition, it would still be subtraction to check your work or find the answer in this case.)
Hopefully you find this useful :)
Answer:
x=4
Step-by-step explanation:
First of all, the sides of the smaller triangle are multiplied by 5 to make it bigger. So, multiply 4 by 5 which gives you 20. So, 20= 3x+8.
Now that we have our equation, we need to isolate the variable.
Subtract 8 from both sides.
20= 3x+8
- 8 -8
Divide both sides by 3.
<u>12</u>= <u>3x</u>
3 3
x= 4
