Answer:
10 and 5
Step-by-step explanation:
10+5=15
10-5=5
Opening up the bracket
-5x-4x+24= -3
-9x= -3 - 24
-9x = -27
divide both sides by -9
x= 3

answer is a
Step-by-step explanation:
18.5+24.25+24.675+17.75=85.175
The factored expression is: 3(5n-6)
The GCF between 15 and 18 is 3. So you would divide both numbers by 3. That would leave you with 5 taking the place of 15 and 6 taking the place of 18. Then you would fill in the blanks. Three multiplied by the expression 5n-6 would give you your original expression of 15n-18.
First of all, triangles angles add up to 180 degrees.
BCD=120. To find BCA subtract 180-120 to get 60 degrees.
We know what ABC is, it equals 85, so far we have 2 angles.
Lets add them up, 85+60=145
Since the angles must add up to equal 180 we're going to subtract 180-145
Which equals 35, BAC=35 degrees.
