Answer:
Step-by-step explanation:
We know a triangle adds up to 180 so:
75+36+ ? = 180
111+ ? =180
? = 69
To find out x, we know that a straight line adds up to 180 so again:
x +69 = 180
x = 111
Answer:
multiply 4 and 8 to get 32
Step-by-step explanation:
After substituting, the expression is ...
4·8 +9/7
The order of operations tells you to do multiplication and division before addition and subtraction. You do them left-to-right. The multiplication on the left is 4·8, so you do that first. The result is ...
32 + 9/7
Now, you can do the division:
32 + (1 2/7)
And, finally, the addition:
33 2/7
___
Or, you could skip the division and go straight to adding a whole number and a fraction:
(32·7 +9)/7 = (224+9)/7 = 233/7
