Answer:
43,51, 86
Step-by-step explanation:
The sum of the angles of a triangle are 180
x+ x+8+2x = 180
Combine like terms
4x+8 = 180
Subtract 8 from each side
4x+8-8= 180-8
4x= 172
Divide each side by 4
4x/4 = 172/4
x=43
x+8 = 43+8 = 51
2x = 43*2 = 86
Answer:
51 red
34 blue
#5 21
Step-by-step explanation:
3+2=5
85/5=17
2/3*17=51/34
top is red bottom blue
You can make 32 sandwiches because 4x1/8=32.
Answer:
16
Step-by-step explanation:
Use the method of PEMDAS (Parenthesis, Exponent, multiplication, division, addition and then subtraction.)
When using this order you would do 10-9 first
23 + 5 * (10-9) - 12
23+ 5 * 1 - 12
then 5 times 1
23 + 5 * 1 - 12
23 + 5 - 12
then 23 + 5 and subract 12 from the solution
23 + 5 - 12
28 - 12 =
16
