what is the value of U?
It's given that WXYZ is a parallelogram. In a parallelogram, the adjacent angles sum up to 180°. Here, 2u - 2 & 3u + 12 together make 180° because they are adjacent angles.
2u - 2 + 3u + 12 = 180
2u + 3u - 2 + 12 = 180
5u + 10 = 180
5u = 170
u = 170/5
u = 34

Convert 220 feet into yards. Round your answer to the nearest tenth.
Answer:
73.33333 Yards = 74 Yards
Step-by-step explanation:
1 yard = 3 feet
220 ft * 1 yard / 3 ft
73.33333 = 74 yd
Step-by-step explanation:
the other answer is essentially correct but wrong for rounding.
again, 1 yd = 3 ft
220/3 = 73.3333... yd
rounded to the nearest tenth this is
73.3 yd

Solve for x and y
Hi
Answer:
x = 10, y = 20
Step-by-step explanation:
Because two sides of the rightmost triangle are congruent, the base angles would follow suit. This means 5x - 10 = 3x + 10. Simplifying this we get:
2x = 20
x = 10
Next, in the other triangle, we can say the same thing, the base angles would be congruent. From this we can say that the other base angle is 4y. Using the exterior angle theorem, we can say that the two angles with x terms add to 4y. This means 3x + 10 + 5x - 10 is 4y. We already know x is 10, so substituting that in we get:
80 = 4y
y = 20

Select all the equations that have {7} as its solution set.
65−2x=6x+9
x2+1=8x−5
3+4x=5x−4
9−x=14x
Step-by-step explanation:
x = 7
3 + 4x = 5x - 4
3 + 4(7) = 5(7) - 4
3 + 28 = 35 - 4
31 = 31
Option C
The equations having the solutions 7 are 65−2x=6x+9 and 3+4x=5x−4. the correct options are A and C.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that we have to check all the equations having solution 7.
Checking option A,
65−2x=6x+9
65 - ( 2 x 7 ) = ( 6 x 7 ) + 9
51 = 51
Checking option B,
x²+1=8x−5
(7²) + 1 = ( 8 x 7 ) - 5
50≠ 51
Checking option C,
3 + 4x = 5x - 4
3 + 4(7) = 5(7) - 4
3 + 28 = 35 - 4
31 = 31
Checking option D,
9 - x = 14x
9 - 7 = 14 x 7
2≠ 98
Therefore, the equations having the solutions 7 are 65−2x=6x+9 and 3+4x=5x−4. the correct options are A and C.

Solve for a
7a - 2b = 5a + b
A. a = 2b
B. a = 3b
C. a = 3/2b
D. a = 2/3b
Answer:
C. a = 3/2b
Step-by-step explanation:
7a - 2b = 5a + b
7a = 5a + 3b
7a - 5a = 3b
2a = 3b
a = 3/2b
Answer:
C. a = 3/2b
Step-by-step explanation:
7a - 2b = 5a + b
7a = 5a + 3b
7a - 5a = 3b
2a = 3b
a = 3/2b

write the equation of a line that passes through the point (-1,-2) and has a slope of -4
Answer:
Y=2x+2
Step-by-step explanation:
The slope-intercept equation of a line :
y = m x + c
Here
m = slope c = y
-intercept
Therefore, the required equation is:
y = 2 xc
Putting the point
( 1 , 4 )
in it as it lies on line, we get:
4 = 2 + c
Therefore
c = 2
So
y = 2 x + 2
is the required equation.
