<span>9-4(2x-1)=45
Multiply -4 by 2x and -1
9-8x+4=45
Subtract 9 from both sides
-8x+4=36
Subtract 4 from both sides
-8x=32
Divide both sides by -8
Final Answer: x= -4</span>
Answer:TO THE 76N POWER
Step-by-step explanation:
You have to find 80% of 20.
Since 80% is equal to 0.8, you multiply 20 by 0.8 to get 16
Answer:
A
Step-by-step explanation:
perpendicular lines are the negative reciprocals of each other, and a pair of these lines intersects at 90 degrees.
In order to find what one part is in a ratio, you have to add the ratio up ( 5+ 3) and divide it by the number you're looking for (56). In this case, you get 56/8, which gives you 7. Therefore, each part is worth 7. You then have to multiply both sides of the ratio (5 and 3) by 7. 5x7= 35. 3x7= 21.
Therefore, 56 divided into the ratio of 5:3 is 35:21
