Answer: -1

Step-by-step explanation: So -3/5 - 2/5, is also -3/5 + -2/5 which when you add those together 2 + 3 is 5 so -3/5 + -2/5 = -5/5 which simplifies to -1

Of the 216 students on the playground three-eighths are wearing white shoes how many children on the playground are not wearing
natka813 [3]
If 3/8 ARE wearing white schoes
Then 5/8 AREN'T wearing white shoes 
because

8/8 - 3/8 = 5/8
8/8 is the same as 1

Therefore, 
5/8 x 216/1 = y
If this is mental maths then,

You can cancel the 216 by 8 because the denominator of 5/8 is 8 to make 27

Therefore, the answer is 135

Using the breaking apart method,what is the best way to multiply 8 by 7?
Veseljchak [2.6K]
If we multiply 8 and 7 we get the answer:
8 x 7 = 56
Now we are going to break apart the number in such a way that we still get the answer 56.
we can split 8 into 2 equal parts 4 and 4, so
8 = 4+4
but 7 cannot break apart in equal part so,
(4+4) x 7 = 56
we can also add 7,  8 times or add 8 7 times and still get the answer 56,
7+7+7+7+7+7+7+7=56
8+8+8+8+8+8+8 = 56

Please help asap need it done. What is the measure of ∠CED and ∠ACD?
worty [1.4K]

Answer:

m\angle CED= 64\°  

m\angle ACD=124\°  

Step-by-step explanation:

In the figure given:

∠ABC = 93°

∠BAC = 31°

∠CDE = 60°

To find ∠CED and ∠ACD.

Solution:

In triangle ABC, we are given two vertex angles. We can find the third angle as angle sum of triangle = 180°.

∠ABC = 93° , ∠BAC = 31°

∠BCA=  180\°-(93\°+31\°)

∠BCA = 56°

m\angle BCA+m\angle ACD=180\°    [Supplementary angles forming a linear pair]

m\angle ACD=180\°-56\°

m\angle ACD=124\°   (Answer)

In triangle CDE:

m\angle CDE+m\angle CED = m\angle ACD   [Exterior angle theorem :Exterior angle of a triangle is equal to sum of opposite interior angles ]

60\°+m\angle CED = 124\°

m\angle CED= 124\°-60\°

m\angle CED= 64\°      (Answer)
