Answer:
-51
Step-by-step explanation:
Let's do order of operations.
10+8-70-(-1) <- We did negative 7 times 10.
18-70-(-1) <- We did 10 plus 18.
-52-(-1) <- We did 18 minus 70
When you open the () we get:
-52--1
Negative minus a negative equals a positive.
-52+1=
-51
First you would divide 48 by 4 which equals 12.
after this you are left with 15-?=12.
?=3
Answer:
c = 0
Step-by-step explanation:
There can only be one possibility to make this equation make sense. If we were to do any number greater than 0, the equation wouldn't work.
If c = 0
9(0) + 27 = 27
0 + 27 = 27
27 = 27 :)
If c = 1
9(1) + 27 = 27
9 + 27 = 27
36 ≠ 27 :(
U cant simply 7/15 and also 3/28
Answer:
22, 68
Step-by-step explanation:
(Complementary means that the angles together equal 90 degrees)
x + x + 46 = 90
2x + 46 = 90
2x = 44
x = 22
22 + 46 = 68
