Answer:
y = 40
Step-by-step explanation:
Lets make an equation to represent the sum of the angles:
We know that the sum of angles of triangles equals 180 degrees. So based on this knowledge, the equation is :
2y + y + 10 + 50 = 180
Now we simplify:
2y + y = 3y
10 + 50 = 60
So our new equation is 3y + 60 = 180
Now all we have to do is simplify:
3y + 60 = 180
3y + 60 -60 = 180 - 60
3y = 120
3y / 3 = 120 / 3
y = 40
So the answer is 40 hope this helped
Answer:
S = E - 3
Sue is 53 inches tall.
Step-by-step explanation:
Let Sue's age be represented by S and Ed's by E
Equation:
S = E - 3
E = 56 inches
S = 56 - 3 = 53 inches
Answer:
58 number of dimes.
A. $5.8
B. 131.602 grams.
Step-by-step explanation:
A U.S. dime has a thickness of 
mm.
Now, Gary has a stack of dimes that is 
mm in height.
Therefore, Gary has 
dimes in total.
A. Now, each dime is equivalent to $0.1.
Therefore, the total value of the dimes that Gary has is $(0.1 × 58) = $5.8.
B. If each dime weighs 2.269 grams, then the mass of the entire stack of dimes will be (2.269 × 58) = 131.602 grams. (Answer)
28.96
or rounded it would be 29
