Answer:
x = -1
Step-by-step explanation:
-4(3x-7) =40
Divide each side by -4
-4(3x-7)/-4 =40/-4
3x-7 = -10
Add 7 to each side
3x-7+7 = -10+7
3x = -3
Divide each side by 3
3x/3 = -3/3
x = -1
X = 7 for the question in the picture
Answer:
1 no. answer is -21
Step-by-step explanation:
According to BODMAS
12 + 8 / 2 * 3 - (42 + 3)
= 12 + 8 / 2 * 3 - 45
= 12 + 4 * 3 - 45
= 12 + 12 - 45
= 24 - 45
= -21
The unit rate of the dog is 12.5 rolls per minute. So to get your answer multiply this by 6 and you will have a total of 75 rolls.
