Answer: (with explanation) (ANSWER AT THE BOTTOM)
et P = number of hours that the plumber worked.
let H = number of hours that the helper worked.
since the plumber worked 3 more hours than the helper, the equation for hours worked is
P = H + 3
-----
since the plumber earned 28 dollars per hour and the helper earned 15 dollars per hour, the equation for amount of money each made is the number of hours each worked times the dollars per hour each earned.
this equation is
(28*P) + (15*H) = 213 dollars
-----
both get the same answer.
-----
-----
substitute for P in the money equation since P is the same as H + 3.
equation becomes
(28*(H+3)) + (15*H) = 213
solve for H.
28*H + 28*3 + 15*H = 213
43*H + 84 = 213
43*H = 129
H = 3
-----
if H = 3, then P = 6 because P = H + 3.
-----
6*28 + 3*15 = 213 so your answer is
Plumber works 6 hoursHelper works 3 hours.now to find the amount each earn by themselves, we just have to multiply by 6 or 3 by their hourly earning.
let's do the Plumber first
28x6=168
now the helper
15x3=45
---------
now to check if that was the right answer, let's add them up...
168+45=213
so, our answer is right.
-----------------
The plumber worked for 6 hours and earned $168 and the helper worked for 3 hours and earned $45 dollars. In total, they earned $213.Answer:

Answer 11 :-We have,
[tex]\sf{HM = 5 cm }[/tex]
In square all sides of squares are equalThe perimeter of square
[tex]\sf{ = 4 × side }[/tex]
[tex]\sf{ = 4 × 5 }[/tex]
[tex]\sf{ = 20 cm }[/tex]
Thus, The perimeter of square is 20 cm
Hence, Option C is correct .
Answer 12 :-We have,
[tex]\sf{MX = 3.5 cm }[/tex]
In square, diagonals are equal and bisect each other at 90°Here,
[tex]\sf{MX = MT/2}[/tex]
[tex]\sf{MT = 2 * 3.5 }[/tex]
[tex]\sf{MT = 7 cm}[/tex]
Thus, The MT is 7cm long
Hence, Option C is correct .
Answer 13 :-We have to find the measure of Angle MAT
All angles of square are 90° eachFrom above
[tex]\sf{\angle{MAT = 90° }}[/tex]
Thus, Angle MAT is 90°
Hence, Option B is correct .
Answer 14 :-We know that,
All the angles of square are equal and 90° eachTherefore,
[tex]\sf{\angle{MHA = }}{\sf{\angle{ MHT/2}}}[/tex]
[tex]\sf{\angle{MHA = 90°/2}}[/tex]
[tex]\sf{\angle {MHA = 45°}}[/tex]
Thus, Angle MHA is 45°
Hence, Option A is correct
Answer 15 :-Refer the above attachment for solution
Hence, Option A is correct
Answer 16 :-Both a and b
The median of isosceles trapezoid is parallel to the baseThe diagonals are congruentHence, Option C is correct
Answer 17 :-In rhombus PALM,
All sides and opposite angles are equalLet O be the midpoint of Rhombus PALM
In ΔOLM, By using Angle sum property :-
[tex]\sf{35° + 90° + }{\sf{\angle{ OLM = 180°}}}[/tex]
[tex]\sf{\angle{OLM = 180° - 125°}}[/tex]
[tex]\sf{\angle{ OLM = 55° }}[/tex]
Now,
[tex]\sf{\angle{OLM = }}{\sf{\angle{OLA}}}[/tex]
OL is the bisector of diagonal AMTherefore,
[tex]\sf{\angle{ PLA = 55° }}[/tex]
Thus, Angle PLA is 55° .
Hence, Option C is correct

Find the missing variable. 3k+4(-k+2)=14k-22
Answer:
k=2
Step-by-step explanation:
Expanding gives
[tex]3k-4k+8=14k-22[/tex].
Further simplification yields
[tex]-k+8=14k-22[/tex]
[tex]15k=30[/tex]
[tex]k=2[/tex].
Step-by-step explanation:
Use the Distributive Property:
[tex]3k - 4k + 8 = 14k - 22[/tex]
[tex] - k + 8 = 14k - 22[/tex]
Add k to both sides:
[tex]8 = 15k - 22[/tex]
Add 22 to both sides:
[tex]30 = 15k[/tex]
Divide each side by 15:
[tex]2 = k[/tex]

Answer:
D. y, because ΔJHK ~ ΔLMK.
The triangle is tilted and has the same angle and sides.
ΔJHK matches with ΔLMK fully.
Answer:
the last one : y
Step-by-step explanation:
the angle KML means the angle at M.
JHK and LMK are similar triangles. that means that all angles in one triangle are the same in the other triangle.
one angle is 90°. the second angle is 65°.
that leaves the third angle to be y (or actually 25°).

If Krista wants the pen to be four times the area it is now
(5 feet long by 4 1/2 feet wide), what are two ways she could change
the length and/or width to give her that new area?
What would the new area be?
The two ways she could change the length and/or width are;
Multiply the length by a factor of 4 while leaving the width constantMultiply the width by a factor of 4 while leaving the length constantThe new area of the pen would be; 90ft²
Area of a penThe dimension of the pen given is;
5 feet long by 4 1/2 feet wideHence, the initial area of the pen is;
5 × 4.5 = 22.5 ft².Hence, to make the pen four times it's present area; Krista may multiply either of the length or width by a factor of 4.
And hence, the new area is; 22.5 × 4 = 90ft²

CAN SOMEONE PLEASE HELP ME PLEASE PLEASE!!!
Step-by-step explanation:
this is really simple : we only need to put the given x and y coordinate values into both equations and see, if both equations remain true.
(-2, -1) means x = -2, y = -1
first equation :
-1 = 3×-2 + 5 = -6 + 5 = -1
so, -1 = -1
true.
second equation :
-2 + -1 = -3
-3 = -3
true.
therefore, (-2, -1) is a solution to the linear system.

Carla’s team won 3 of its 5 games played. Elena’s team won games at the same rate. How many games were played if Elena’s team won 12 games?
3/5=12/x
reciprical of both sides
5/3=x/12
times twelve on both sides
x=20
Answer:
7.2 games, 2.4 times rate.
Step-by-step explanation:
Carla's team won 3 of 5 games which is 3/5 aka 60%.
Elena's team won games at the same rate which means Elena's team won about 7 games since it's 7.2/12 (60%). They won at the rate of 2.4 times while Carla wins at 3/5 rate.
