Answer:
10xy-5
Step-by-step explanation:
15xy-4+2xy-7xy-1 is the given expression.
I assume the directions say to simplify.
Group the xy terms together and group the constants together.
15xy+2xy-7xy-4-1
This is a demonstration of the commutative property.
Now I will use the distributive property to rewrite the first 3 terms as a multiplication:
(15+2-7)xy-5
10xy-5
Answer: X= 25 degrees
Step-by-step explanation:
A triangle is 180 degrees.
115+40=165
180-165=25 degrees
The answer is B) 20
Because you have 5 brands and you combine each with the 4 others, so 5*4=20
1.086 rounded to the nearest whole number is 1
To use division to find the decimal equivalent of a rational number, divide the top number by the bottom number. You will get a decimal number.
