9. D X=16, Y=10
10. D X=7
Answer:
8.) c
9.) d
10.) d
Step-by-step explanation:
8.) These are same side interior angles so they have a different measures that equal up to 180.
75 + 4x - 9 = 180 (collect like terms)
4x + 66 = 180 (subtract 66 on both sides)
4x = 114 (divide by 4 on both sides)
x = 28.5
9.) 8x -14 and 5x + 34 are alternate exterior angles so the equal the same measure.
8x - 14 = 5x + 34 (add 14 on both sides)
8x = 5x + 48 (subtract 5x on both sides)
3x = 48 (divide by 3 on both sides)
x = 16 NOW PLUG IN TO 8x - 14 to find y
8(16) - 14 + 5y + 16 = 180 (distribute and collect like terms)
130 + 5y = 180 (subtract 130 on both sides)
5y = 50 (divide by 5 on both sides)
y = 10
10.) They have the same measure they are alternate exterior angles
16x + 22 = 134 (subtract 22 on both sides)
16x = 112 (divide by 16 on both sides)
x = 7

A free cable sparkling juice calls for 1 1/2 quarters of sparkling water and 3/4 course with grape juice how many sparkling how much sparkling water would you need to mix with 9 quarts of grape juice
Answers
Answer: 18 quarts
Step-by-step explanation:
As per given,
Quantity of sparkling juice is proportional to quantity of course with grape juice.
Given: A free cable sparkling juice calls for [tex]1\dfrac12[/tex] quarters of sparkling water and [tex]\dfrac34[/tex] course with grape juice .
Let x be the quantity of sparkling water need to mix with 9 quarts of grape juice.
then, by equation of direct proportion , we have
[tex]\dfrac{1\dfrac12}{\dfrac34}=\dfrac{x}{9}\\\\\Rightarrow\dfrac{\dfrac{3}{2}}{\dfrac{3}{4}}=\dfrac{x}{9}\\\\\Rightarrow\ \dfrac21=\dfrac{x}{9}\\\\\Rightarrow\ x=9\times2\\\\\Rightarrow\ x=18[/tex]
Hence, the quantity of sparkling water need to mix with 9 quarts of grape juice = 18 quarts

Please help meeeeee!!!!
Answers
Answer:
x = 30
Step-by-step explanation:
As we know, the angles inside of a triangle added together all equal 180°, so you would combine 3x + 2x + x = 180°. And then from there you can solve.
3x + 2x + x = 180°
[Combine like terms] 6x = 180°
[Divide 6 from both sides of the equal sign] x = 30°

Which equation is true of x is 3.5
Answers
Answer:
B
Step-by-step explanation:
Because 4 times 3.5 equals 14 and minus 3 equals -11 so its B.
Answer:
Your answer is B.
Step-by-step explanation:
The reason is because:
3-4x=-11
turns to
-4x=-14
when you subtract 3 from both sides then divide both sides by negative 4
and you get:
x=-14/-4
if you simplify -14/-4 your final answer will be
7/2 which equals 3.5: x=3.5

What is the midpoint of the segment shown below ? A. (1,5) B. (2,5), C ( 1 1/2,5), D. (2 1/2, 5)
Answers
The midpoint of the line segment is (2,5) (option B)
How do you find the midpoint of a line segment in a coordinate?When given the end points of a line segment, you can find out its midpoint by using the midpoint formula. As the name might have already suggested, midpoint is basically the halfway between two end points. All you need to do is dividing the sum of x-values and the sum of y-values by 2.
The sum of x coordinate is -1+5 = 4
half of sum of x coordinate = 4/2 = 2
The sum of y coordinate = 5+5= 10
half of sum of y coordinate = 10/2 = 5
therefore the midpoint of the line is ( 2,5)

The midpoint of AB is M(4.-2). One endpoint is A(-2,6). What is the length of AB ?
5 units
10 units
20 units
28 units
None of these
Answers
Answer:
AB = 20 units
Step-by-step explanation:
Given the coordinate midpoint M(4.-2) and A(-2,6), we are to find the length AB. To get that, we need to get the coordinate of B first as shown
M(X, Y) = [(x1+x2/2, y1+y2/2]
X = x1+x2/2
4 = -2+x2/2
8 = -2+x2
x2 = 8+2
x2 = 10
Y = y1+y2/2
-2 = 6+y2/2
-4 = 6+y2
y2 = -4-6
y2 = -10
Hence the coordinate of B is (10, -10)
Recall that A =(-2, 6)
Get AB;
AB = √(x2-x1)²+(y2-y1)²
AB = √(-2-10)²+(6+10)²
AB = √(-12)²+(16)²
AB = √144+256
AB = √400
AB = 20 units

triangle
Answers
Answer:
48 meters
Step-by-step explanation:
3*4 = 12
5*4 = 20
4*4 = 16
These are the sizes when the triangle enlarges with a scale factor of 4.
To find perimeter, you add the sides together
12+20+16 = 48
The perimeter is 48 meters
The perimeter of larger triangle is 48m.
Given that,

LIGHTING Kyle is buying strands of outdoor lights for his luau. The total cost of the strands can be modeled by the function f(c) = 8.97c. He received an email with a coupon code to receive $5 off his online purchase. A. Write a function g(c) that represents the cost of purchasing strands of lights with the $5 discount. B. Find the cost of purchasing 6 strands of lights before and after the discount. How about this one anyone
Answers
Answer:
Step-by-step explanation:
A. Function before discount:
f(c)= 8.97c
This means that cost per strand of outdoor light is $8.97 and c is number of strands of outdoor light bought. Therefore to model the function g(c) after he has received a $5 discount on his purchase(total purchase)
g(c)=8.97c-5
B. cost of 6 strands of light before discount
f(c)= 8.97×6= $53.82
cost of 6 strands of light after discount
f(c)=8.97×6-5= $48.82
