Step-by-step explanation:
Step 1: Define
2z - 3 = 1
Step 2: Solve for z
Add 3 on both sides: 2z = 4Divide 2 on both sides: z = 2The table below would represent a proportional relationship except for one y-value. Identify which y-value prevents the table from representing a proportional relationship. Then, select the value that would make the table proportional.
X 1.5, 2, 4, 4.5, 7
Y 6, 8, 16, 16.5, 28
Alternative values 17, 18, 18.5, 19.5, 20
9514 1404 393
Answer:
non-proportional y-value: 16.5
corresponding proportional y-value: 18
Step-by-step explanation:
Each y-value is 4 times the corresponding x-value except for (x, y) = (4.5, 16.5).
The correct proportional values would be (4.5, 18).

2(x+7) + 3(x+1)
pls help
Answer: 5x +17
Step-by-step explanation:
2(x +7 ) + 3(x +1) Apply the distributive property to break it down
2(x) + 2(7) + 3(x) + 3(1)
2x + 14 + 3x + 3 Now combine like terms
5x + 17
Answer:
2x+14+3x+3
5x+17

Answer:
The measure of angle two is 47 degrees (first triangle), and the measure of angle four is 42 degrees (second angle)
Step-by-step explanation:
Remember that all triangles have a full measurement of 180 degees.
Since measure one is is 65 degrees, we need to add 65 and 68, which is 133 degrees.
Now we subtract 180 - 133 = 47.
The measure of angle two is 47 degrees.
Since the angle of measure three is 89 degrees, we need to add 89 + 49, which is 138 degrees.
180 - 138 = 42.

What is a correct name for ange 5?
Answer: KVL
Step-by-step explanation:
This would be the correct name for the angle since the V needs to be in the middle of the answer. In the angle you can see L V and K all pass 5 making it the correct name for the angle
Margaret goes to the county fair with $35. Rides cost $3
Helppp ASAP!!
each.
Which is the function that gives the amount of money m that Margaret has as a function of the number of rides that she takes?
Om = 3r +35
Om = 35r - 3
Om = 35r +3
Om = -3r + 35
Answer:
Om= -3r+35
Step-by-step explanation:
If she pays 3 dollars for a ride then that means she is subtracting 3 dollars from the amount she had which is 35. So it would be -3 times the amount of rides she rode plus 35. Hope this helped you!! Give brainliest.

Without a calculator, choose the statement that best describes the value of√74.
Choose 1 answer:
A: the value of √74 is between 8 and 8.5
B: the value of √74 is between 8.5 and 9
C: the value of √74 is between 9 and 9.5
D the value of √74 is between 9.5 and 10
Answer:
B
Step-by-step explanation:
Well you can get rid of c and d since 9^2 = 81. so 74 is less than 81 so it's definitely less than 9. Now, we know it's between 8 and 9. try multiplying 8.5 x 8.5 = 72.25. So our ranges are
A) 64 - 72.25
B) 72.25 - 81.
74 falls between 72.25 - 81. So it'll be B

The shaded region of the design shown is to be painted red. What is the area, in square units, of the shaded region? (Use = 3.14)
A 43.0
B 62.8
C 121.5
D 137.2
Answer:
A.43.0
Step-by-step explanation:
area of rectangle= l*w=10 units *20 units= 200 units^2
area of the 2 circles:
diameter= 20/2=10 units
r=d/2= 10/2=5 units
area of a circle= 3.14*r^2
=3.14*5*5
=78.5> the 2 circles are identical then they have the same area
area of the shaded region= area of the rectangle- 2*area of one circle
= 200- (2*78.5)
=200-157
=43.0
therefore the area of the shaded region is 43.0 units^2
Together, siblings Brandon, Brooke, Trent, and Trisha owe their parents $100. Write a number sentence to show how much each sibling owes if they share the debt equally. (Be sure to use negative numbers where appropriate.)
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that four siblings Brandon, Brooke, Trent, and Trisha owe their parents $100.
The number sentence that will show how much each sibling owes if they share the debt equally will be:
= $100 ÷ 4
= $25
This mean that each child owes $25
Can someone help me find x and y?
CAN ANYBODY HELP ME WITH THIS JUST WITH 7 TO 12 PLEASE IT IS FOR AN GRADE!!
Answer: I think there is a mistake for the first one because I did the math and I got 200 added but then there are more answers to this one, I added all the others by 200 and got the next number but then when I got to 6,300 I can't get the 6,700. I get something else, I add 6,000 with 200, and then I get 6,200 instead of getting 6,300. Then I added that 6,200 and 200 and got 6,400. I am confused with the second one, can you please help me understand that one. The third one is also confusing, The one is 12 nuggets eaten per minute. The fifth I am not sure if that is a solvable question, The sixth one I am not sure but I think that it is 0.066667. The seventh one doesn't even make any sense to me.
Explanation: I am sorry this was so long, I was trying to make sense of these questions. Also if this is ALL wrong sorry for even trying.

Answer:
A) 6
Step-by-step explanation:
The angle 12x is the same angle as the one below 108 degrees. They are supplementary angles so they add up to 180 degrees. 180-108 = 72, 12x = 72 divide each side by 12, x = 6 :)

at the 30-60-90 triangle has rules
30=>k
60=>k(square root of) 3
90=>2k
so in this triangle 60=> see 9
k(square root of) 3=9
k=9/(square root of) 3
2k=18/(square root of) 3
at the 45-45-90 triangle rules are
45=>2k
45=>2k
90=>[2k/(square root of 3)] (square root of) 2
x=[18/(square root of 3)].(square root of 2)
x=18(square root of 2)/square root of 3
