Answer:blank 1=12 blank 2=16 blank 3= 48
Step-by-step explanation:
Answer:
J=40º, K=60º, H=80º
Step-by-step explanation:
since all angles of a triangle add up to 180º, we can make an eqaution.
3x+2x+4x=180
9x=180
x=20
J=2x=20x2=40º
K=3x=20x3=60º
H=4x=20x4=80º
Answer:
x+2x+6=87
Step-by-step explanation:
let x represent the first number. 2x+6 would represent the second number since it's 6 more than (which would be addition) twice the first number (so you'd multiply the first number (which is represented by x) by 2. then, you'd set up the equation to be equal to 87.
so, the equation would be:
x+2x+6=87
The answer is the 2nd one because on the left side you combine like terms and when you do your sum is bigger than 5 so b is your answer
