Answer:
23x + 49
Step-by-step explanation:
4 (5x+15-2)+3x-3
subtract the numbers
4 (5x+13)+3x-3
distribute 4
20x+52+3x-3
23x+52-3
subtract
23x+49
Answer: 1. x= -12 2. x= 12
Step-by-step explanation:
1. 5(+3)=−45
5x+15−15=−45−15
5x= -60
5x/5 = -60/5
x = -60/5
x= -12
2. 1x/2−4=2
x/2 -4=22−4+4=2+4
/2=6
2⋅2=2⋅6
x=2⋅6
x= 12
All you have to do is divide 40 by five and you've got your answer. I don't have the required diagram, but that would basically mean that the average lifespan of a guinea pig is about eight years, which is being generous in reality (they usually live for about 4-8 years in real life).
1: (-3)2= -6
2: (-6)4= -24
3: (-1)8= -8
Answer: x=7
Step-by-step explanation:
Since AB is a bisector, it cuts the angle in half, and since we know that the angle is a right angle, we know it’s 90 degrees, so knowing that you use the equation 7x-4= 45 (since 45 is half of 90), add 4 to both sides so you have 7x=49, the divide 49 by 7 and you get 7, so x= 7
