Answer:
4a.)
so the equation for this can be:
3/4 divided by 1/8
also, how many times can 1/8 go into 3/4
3/4=6/8
1/8 goes into 6/8 6 times, so 6 cupcakes out of the 8 cupcakes(or however many cupcakes there are - the problem doesn't specify that)
4b.)
3/4 ÷ 1/8
10.)
each square is 2 units wide(or long-whatever you wanna call it)
i don't really know how to explain this one, but i can just give you my answer (you can jut count up the squares along the outside of the polygon-the meaning of perimeter)
76 units
the bottom left one (i cant read the question number sorry)
1/10 of 237=
1/10*237=
237/10=
23.7
19.)
reflection pretty much means mirroring, so if you add the distance from E to the y axis and M to the y axis, you will get 10 (|-5|+|5|)
point m is in the 1st quadrant (sorry i don't really know how to explain this one either)
hope this helped!!
For the first one, if you add 2 equations together, you will get:
4 = 4, which is trivial, irrelevant to x. So it means it has infinite solutions
For the second one, if you add them up, you will get 0 = 12, which is incorrect, and irrelevant to x as well. So it means it has no solutions
Complementary angles ⇒ the angles add up to 90°
∠A and ∠B are complementary ⇒ ∠A + ∠B = 90°
∠A + ∠B = 90°
Plug in the values for ∠A and ∠B:
(3x - 8) + (5x + 10) = 90
Open the brackets:
3x - 8 + 5x + 10 = 90
Combine like terms:
8x + 2 = 90
Subtract 2 from both sides:
8x = 88
Divide both sides by 8:
x = 11
Answer: x = 11
The answer is 29
29 is the answer because:
Following PEMDAS
5*6=30
3+30=33
33-4=29
Y= -4x+8.... all u had to do is subtract 4x to the other side and get that answer
