(100 + 70) ÷ 10
170 ÷ 10
17
therefore the answer is 17 trains
As I cannot help you do your assignment since you didn't upload the questions, I can just give you the instructions.
I believe you are supposed to open the Student Guide that your cursor is hovering over (the boxed line in the picture) and then solve the problems (or do) the stuff inside. Then, you take a picture of your work/answers and upload that to the File Upload below.
Answer:
137°
Step-by-step explanation:
All angles in a triangle add up to 180° always.
Now imagine the two smaller shapes as a bigger triangle, CED. The measure of angle CED is 89°, and CDE is 48°. Do the math, and angle DCE is 43°.
But notice how the corresponding sides of the two smaller shapes are congruent. (CX=XE, and DY=YE) Meaning, the measure of angle C is equal to the measure of angle YXE.
We're almost there. CXY (what we're looking for) and YXE are supplementary angles, meaning the angle measures add up to 180. 180-43 = 137°.
Answer:
NO SOLUTION
Step-by-step explanation:
3/2x-2/3x=2
find the common denominater which is 6 and whatever you do to the bottom you have to do to the top, in turn you'll get
6/6x-6/6x=2
In this case since their both the same you subtract x from x and when you do that you get,
NO SOLUTION = 2
