Answer:
A
Step-by-step explanation:
The root 5's cancel each other out.
4x-2x = 2x
Therefore
2x/3 is the final answer
Answer:
A.
Step-by-step explanation:
The y-intercept starts at -2
The slope is because it goes up 2 and 5 to the right.
The equation would be
Answer: 55.7 m2
Step-by-step explanation:Step 1
3x2=6
3x9.9=29.7
10x2=20
Step 2
6+29.7+20=55.7
The answer is indeed 40 K.
Answer: In first question answer is -28x+4
In second question required inequality is 3x+100 < 2x-250
Step-by-step explanation:
1. Since, here the given expression is 4(x+5)-8(2+4x)
= 4x+20-16-32x ( By distributive property)
=-28x +4 ( By operating like terms)
2. Here, let the number is x.
Then according to the given question, three times the number of candy is increased by 100
That is, 3x+100
And, 250 less than the two times of the candy
That is, 2x-250
And, 3x+100>2x-250
Which is the required expression.
Hence she should subtract 250 from 2x not 2x from 250.
