If ∠C and ∠D are complementary angles, m∠C = (4x + 3)°, and m∠D = (15x – 8)°, find m∠D
Answers
Answer:
52
Step-by-step explanation:
complementary angles meaning sum of both angles is 90
so equations is
(4x + 3) + (15x – 8) = 90
x=5
insert x into angle d equation
d=15(5)-8
d=60-8
d=52
Answer:
<D = 67 degrees

find the ordered pair (x,y) that is a solution to the equation
x-4y=8
Answers
Answer:
(4,-1)
Step-by-step explanation:
x-4y=8
-4y=-x+8
y=1/4x-2
The solution to the equation x - 4y = 8 is an ordered pair (4,-1).
What is the solution to the equation?A solution to an equation is a number that can be substituted for the variable to provide a true number statement.
The equation is given in the question, as follows:
x - 4y = 8
To determine the ordered pair (x,y) of the solution, substitute the value of x = 4 in the equation, and solve for y:
4 - 4y = 8
- 4y = 8 - 4
- 4y = 4
y = - 4/4
Divided by -4 into both sides of the equation, we get
y = - 1
Thus, the solution to the equation is an ordered pair (4,-1).

A pair of parallel lines is cut by a transversal. One of the angles formed measures 58°. Which statements about the other seven angles formed are true?
There are three more angles with the same measure.
All the other angles have the same measure.
The rest of the angles measure 122°.
Only three of the angles measure 122°.
Four of the angles measure 122°.
Answers
Answer:
There are three more angles with the same measure. A pair of corresponding angles and a pair of vertical angles.
Step-by-step explanation:
==========================================================
Explanation:
I recommend drawing out a diagram as shown below. Angle 1 is 58 degrees.
Angle 3 is also 58 since the two angles are congruent vertical angles.
Angle 5 is equal to angle 1 due to them being corresponding angles (this only works if the lines are parallel)
Angle 8 is congruent to angle 5, for similar reasonings with angle 3 above.
So that means we have three additional angles that are 58 degrees: angle 3, angle 5, angle 8
-------------------
The rest of the angles are 122 as the diagram shows. We have four angles that make up the rest of the angles. Angle 2 and angle 1 add to 180, so
x+y = 180
58+y = 180
y = 180-58
y = 122
And you'll find the other unknown angles fit this pattern as well. Or you could use corresponding angles and vertical angles to fill out the rest of the diagram.

Emilio 4(h−2)

Answers
Answer:
Four siblings have a dog walking business. The table shows the hours worked by each sibling. Each sibling earns $25.50 per hour and the total number of hours worked is represented by 10h+15 , where h represents the number of hours Michael worked.
Martin 2.5h+3
Emilio 4(h−2)
Michael h
Mario 31
The algebraic expression is the combination of variable and constants with some mathematical operation between them. The Earning of the four siblings are $357, $244.8, $112.2 and $790.5 respectively.
What is an Algebraic expression?An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
Given that,
The earning of the siblings per hour is $25.50.
Total number of hours worked is 10h + 15.
As per the problem the value of h can be found by equating the total number of hours to the sum of hours worked by each sibling as given in the table as follows,
2.5h + 3 + 4(h - 2) + h + 31 = 10h + 15
⇒ 2.5h + 3 + 4h - 8 + h + 31 = 10h + 15
⇒ 7.5h + 26 = 10h + 15
⇒ 2.5h = 11
⇒ h = 11 / 2.5
⇒ h = 4.4
Thus, the earning of each sibling can be calculated by substituting h = 4.4 in their working hour and multiplying it by $25.50 as follows,
Earning of Martin is given as,
(2.5 × 4.4 + 3) × $25.50 = $357
Earning of Emilio is given as,
4(4.4 − 2) × $25.50 = $244.8
Earning of Michael is given as,
4.4 × $25.5 = $112.2
Earning of Mario is given as,
31 × $25.50 = $790.5
Hence, the earnings of the four siblings are as Martin : $357, Emilio : $244.8, Michael : $112.2 and Mario : $790.5.

To make 16 hamburger patties that each weigh 1/3 pound, you need 16/3 pounds of beef. Write 16/3 as a mixed number.

I hope this helps you learn how to change improper fractions to mixed numbers!
solution:
if you were to divide 16 and 3, you wouldn’t have an exact whole number to divide it by. The closet would be 5. 5x3= 15 with a remainder of 1. You take the denominator and make it 1/3. Now, you have your whole number 5 and fraction 1/3. That would mean the answer is 5 1/3
zach is 4 years older than twice his sister maya's age. zach is 28 years old.
which expression would you use to represent zach's age?
Answers
Answer:
Lets take:
Z - Zach
M - Maya
Now forming the equation:
Z = 2M+4
Z = 28
Solving:
2M+4 = 28
2M = 24
M = 12
Zach's age is 28; whereas Maya's age is 12.
Answer:
2m + 4 = 28
Step-by-step explanation:
Let m be Maya's age
4 years older than twice his sister Maya's age = 2m + 4 If "4 years older than twice his sister Maya's age" and "Zach is 28 years old" are equal, then this is how you'd write it: 2m + 4 = 28I hope this helps!
