Answer:
6.
Step-by-step explanation:
Proportional triangles once again:
24/8=18/x
18*8=144
144/24=6
:)
The rotation of the triangle is 270 degrees clockwise, or 90 degrees counterclockwise. Most commonly, clockwise measurements are used when it comes to rotations.
I hope this helped. Let me know if I was correct please.
Answer:
The total number of boxes of canned food brought in by the three grades is 17.63 boxes
Step-by-step explanation:
To find the total number of canned foods brought in by the three grades, we will have to add the number of canned foods brought by each of the grades to each other. Careful attention has to be paid to the decimal points.
Canned foods brought by 6th graders: 5.75 boxes
Canned foods brought by 7th graders: 6.5 boxes
Canned foods brought by 6th graders: 7/1.3 boxes
We may have a slight challenge adding in 7/1.3 boxes to the other figures. What we can do now is to evaluate it to a decimal value by dividing it up.
7/ 1.3 will be the same thing as 7 divided by 1.3 = 5.38 boxes.
hence, we have 5.75 +6.5+ 5.38= 17.63 boxes
The total number of boxes of canned food brought in by the three grades is 17.63 boxes
The equations are:
x + y = 200
x = y - 40; substituting x from this equation to the first:
y - 40 + y = 200
2y = 240
y = 120
Corresponding value of x:
x = 120 - 40
x = 80
The solution to this system is (80, 120)
X-y=7
y=3x+12
y-3x=12
+
-y+x=7
=
-2x=19
x=-9.5
y=-16.6. Hope it help!
