Answer:
x = 72
Step-by-step explanation:
The sum of interior angles of a pentagon is (5-2)(180°) = 3·180°. The sum of the two right angles is 180°, so we can write the equation ...
180° +2x° +x° +2x° = 3·180°
5x = 2·180 = 360 . . . . divide by °, subtract 180
x = 360/5 = 72 . . . . . . divide by 5
The value of x is 72.

Find the value of b if the graph of the equation y=−5x+b goes through the G(4, 3) point.
Answers
Answer:
b = 23
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Define
y = -5x + b
G(4, 3)
Step 2: Find y-intercept b
Substitute point: 3 = -5(4) + bMultiply: 3 = -20 + bAdd 20 to both sides: 23 = bStep 3: Write linear equation
y = -5x + 23
Answer:
The answer is y=-5x+21.5 --- B=21.5

A map shows a section of Interstate 94 that forms a straight line. A family plans to drive 72 miles on Interstate 94 from St Paul, MN to Elk Mound, WI. They drive for 20 miles, and then decide they will stop halfway through their trip to eat. How much farther do they need to drive before they stop for dinner?
Answers
Answer:
16 miles
Step-by-step explanation:
Given that:
Total distance of the trip = 72 miles
They have decided to stop half way their trip i.e. they will stop at a distance [tex]\frac{72}{2} =36[/tex] miles from the starting point.
Also, given that they have already traveled for 20 miles.
To find:
How much farther do they need to drive before they stop for dinner?
Solution:
Distance already covered = 20 miles
Distance to be covered before stopping for dinner = 36 miles
Distance to be covered more = Total distance to be covered before stopping - Distance already covered
[tex]\Rightarrow 36-20 =\bold{16\ miles}[/tex]

Im not 100% sure this is correct but what I did was
Y=2(x-1)^2+6
2(x-1) = 2x -2
Y=2x -2^2 +6
Y=2x -4 + 6

A group of seven golfers paid $345 to play a round of golf. Of the golfers, one is a member of the club and six are nonmembers. Another group of golfers consists of two members and two
nonmembers. They paid a total of $140. What is the cost for a member to play a round of golf, and what is the cost for a nonmember?
Answers
Answer:
member = 15
nonmember = 55
Step-by-step explanation:
m = member, n= nonmember
1m+6n=345
2m + 2n =140 (divide all by 2 )
m + n = 70
m= 70 - n
70-n + 6n =345
70 + 5n = 345
5n = 345-70
5n = 275
n = 275÷5
n = 55
m = 70 - 55 = 15
m=15
