2 answers:
Answer:
B. The error is in step 2, combine to make
not
.
Step-by-step explanation:
We have been an image that represents Grant's solution of an equation. We are asked to find Grant's error.
Let us see our given equation by using distributive property .
Now we will gather like terms.
Upon looking at Grant's work, we can see that he combined incorrectly. Instead of subtracting x, he added x to 3x, therefore, Grant made an error in step 2 and option B is the correct choice.

Answer:
49.7%
Step-by-step explanation:
A cdircle is located within a square.
<u>Area of the circle</u>
Area = , where r = 4 units.
Area Circle = 50.3 units^2
<u>Area of the square</u>
Area = l*w or l^2 for a square, since l = w
Area = (10 units)^2
Area = 100 units^2
<u>Area in the square but outside the circle</u>
This is the difference [Square minus Circle Areas]
Square minus Circle Areas = 100 - 50.3 or <u>49.7 units^2</u>
<u>Probability</u>
The probability of picking a point in the square that is not in the circle is the ration of the two areas: <u>[Outside Circle/Square]x100%</u>
<u></u>
<u>(</u>49.7 units^2)/(100 units^2)x100% = 49.7%

Answer:
48 cats
Step-by-step explanation:
Am interesting factoid about ratios:
The ratio can be separated into fractional parts of
and
. We need to know the cat part.
, so that is the fraction part. Then, we multiply this fraction by 168 to get the total number of cats. This number is 48.
