Answer:
x = 6
Step-by-step explanation:
To get rid of the fraction at the left side of the equation, multiply both sides by 4
20x + 60 = 180 now subtract 60 from both sides
20x = 120 divide both sides by 20
x = 6

How is a trapezoid different from a rectangle?
A. It’s is not a closed polygon
B. It has five legs and a diagonal
C. It has one pair of parallel sides
D. It has all pairs of parallel sides
Answer:
C.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
A can't be right because rectangles and trapezoids are both closed polygons.
B can't be right because both shapes can't even have 5 legs.
C is right because triangles only have one pair of parallel sides and rectangles have two pairs.
D trapezoids don't have two pairs of parallel sides because two sides intersect eventually.

y varies jointly as x and z. If y = 5 when x = 3 and z= 4, find y when x = 6 and z = 8.
Answer:
y = 20
Step-by-step explanation:
Given y varies jointly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 5 when x = 3 and z = 4
5 = k × 3 × 4 = 12k ( divide both sides by 12 )
[tex]\frac{5}{12}[/tex] = k
y = [tex]\frac{5}{12}[/tex] xz ← equation of variation
When x = 6 and z = 8 , then
y = [tex]\frac{5}{12}[/tex] × 6 × 8 = [tex]\frac{5}{12}[/tex] × 48 = 5 × 4 = 20

Cody’s favorite snacks are pecans and almonds. At the Nut Haus, pecans sell for $2.00 a pound and almonds sell for $4.50 a pound. Cody wants to buy a mixture of nuts that weighs 6 pounds. He has $15.25 to spend on pecans and almonds.
Part A
Identify the two variables in the problem situation.
Part B
Write a system of two linear equations in two variables that could be used to determine the number of pounds of pecans and almonds Cody could purchase at the Nut Haus.
Answer:
Part A
The two variables are the amount of pounds that we dont know yet for the nuts and the almonds so we would have to put x for the amount of pounds for pecans and y for the amount of pound for nuts
Part B
2x + 4.50y = 15.25
Step-by-step explanation:
Step-by-step explanation:
x = pounds of pecans bought
y = pounds of almonds bought
x + y = 6
x×2 + y×4.5 = 15.25
x = -y + 6
(-y+6)×2 + y×4.5 = 15.25
-2y + 12 + 4.5y = 15.25
2.5y = 3.25
y = 3.25 / 2.5 = 3 1/4 / 2 1/2 = 13/4 / 5/2 = 13×2 / 4×5 =
= 26/20 = 13/10 = 1.3 pounds
x = -y + 6 = -1.3 + 6 = 4.7 pounds
Cody could buy 4.7 pounds of pecans and 1.3 pounds of almonds.

find two numbers whose sum is 114 and the difference is 58.
(written as an equation please)
[tex]⇒[/tex]
x + y = 114
x - y = 58
Add the equations downward:
2x + 0y = 172
2x = 172
x = 86
x + y = 114
86 + y = 114
y = 114 - 86
y = 28
Answer: The two numbers are 28 and 86.

which of the following theorems proves that abc~def?
Answer:
D but read below.
Step-by-step explanation:
I take it that the symbol ~ stands for similar. If that is so, then the answer you want is AA, because if 2 angles in a triangle are equal, then all 3 are. So if any 2 equal angles in one triangle are equal to 2 angles in another, then the two triangles are similar.

Plzzz help
Answer:
4. Positive (+)
5. Negative (-)
Step-by-step explanation:
When the exponent is even, the value will be positive (+). If the exponent it's odd, the value will be negative (-). This only applies when the number in the parenthesis is a negative number.
4) Solution:
→ (-6)⁴
→ -6 × -6 × -6 × -6
→ +1296
Ans: Positive
5) Solution:

Find the coordinates of the other endpoint when you are given the midpoint (point M) and one of the endpoints (point P).
P = (10, 6) and M = (-4, 8)
Answer:
(-18, 10)
Step-by-step explanation:
If the other end point is Q, the midpoint is ...
M = (P +Q)/2
2M = P +Q
Q = 2M -P = 2(-4, 8) -(10, 6) = (-8-10, 16-6)
Q = (-18, 10)
The other end point is (-18, 10).

Can someone please solve this problem? I’ll mark you at brainlest! (I mostly need help with 10 and down but you can do whatever!)
Answer:
10. 45/6
Step-by-step explanation:
Whatever you do to the top you have to do to the bottom. To get 2 from 6 in the denominator you would have had to divide by 3 so I multiplied 15 by 3 to give make the two fractions equal to each other. If you are not sure if your answers are correct just divide the numerator by the denominator on the calculator and if they are equal values then it's correct.
The area of a trapezoid is 70. 55 square feet. The length of the bases are 11. 4 feet and 5. 6 feet. What is the height of the trapezoid? 4. 15 ft 4. 15 ft2 8. 3 ft 8. 3 ft2.
The height of the trapezoid is 8.3 feet.
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides,4 vertices and edges.
Area of a trapezoid = 0.5 x (sum of the lengths of the parallel sides) x height
70.55 = 0.5 x (11.4 + 5.6) x h
70.55 = 0.5 x (17) x h
70.55 = 8.5h
h = 70.55 / 8.5
h = 8.3 feet
