So,
Jamie has made a 2 x 4 rectangle, composed of squares.
Visualizing this setup, we can first see that the 4 squares lengthwise touch each other in pairs. So that's 4 already.
In addition, notice that there are three columns in the widths. Also notice that each column has 2 pairs of touching sides. So 2 * 3 = 6 more pairs.
6 + 4 = 10
There are 10 pairs of sides that touch each other.
Answer: The space given up by the students is 1/4 of the total space.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
<em> Students must give up half of the exhibit space to the other school.</em> So, we have to divide 5/10 by 2.
5/10 ÷ 2/1 = (5x1 ) / (10 x2 ) = 5 /20
Simplified (by 5) = 1 /4
The space given up by the students is 1/4 of the total space.
Feel free to ask for more if needed or if you did not understand something.
Answer:
C: y+7=2/5(x+4)
Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
You are given m=2/5 and (h, k) = (-4, -7). Put these numbers into the form and simplify the signs:
y -(-7) = 2/5(x -(-4)) . . . . . numbers put into the form
y +7 = 2/5(x +4) . . . . . . . signs simplified . . . . matches choice C
I believe the answer is A because you cannot find x nor y
