First you have to give the number a name. Call it Bob.
6 more than 7 times Bob is 41.
(7 Bob) + 6 = 41
A quadrilaterals angles = 360°
three angles are given, with the fourth as x: 90, 80, 74, x
Add all the angles together and set it equal to 360
90 + 80 + 74 + x = 360
Simplify. Combine like terms
x + 244 = 360
Isolate the x, subtract 244 from both sides
x + 244 (-244) = 360 (-244)
x = 360 - 244
x = 116
116° is your answer
hope this helps
Answer:
using elimination, the best first step is multiply the first equation by -3. multiply the second equation by 3 doesn't do anything to eliminate one of the unknowns. solving for x in the first equation or solving for y in the second equation are the substitution method, not the elimination method.

Answer:
B) 13
Step-by-step explanation:
The computation shows that the year that Helike disappeared is 2248 years in between.
<h3>How to calculate the value?</h3>
From the information, Helike disappearance was denoted as -1/5w. The year that civil year ended was represented as c + 1/4c.
This implies that year Helike disappeared will be:
= c + 1/4c - +-1/5w)
= 2248 years.
Here is the complete question:
The year the Greek city of Helike disappeared is -⅕ times the year the US Civil War ended. Let w represent the year the Civil War ended. Write an expression in terms of w to represent the year of Helike’s disappearance.
Part G
Use the results from Part E and Part F to determine the year Helike disappeared. Express your answer in terms of BC or AD.
Part H
Using the results from parts D through G, write an expression that represents the number of years elapsed between the disappearance of the Greek city of Helike and the end of the US Civil War. Write the expression in terms of c and w. Then solve the expression to find out how many years separate these two events.
