Answer:
7x=42°
8x=48°
Step-by-step explanation:
Sum of all interior angles in a triangle=180°
90+8x+7x=180
90+15x=180
15x=180-90
15x=90
x=90/15
x=6
The measure of each acute angle is 42° and 48°.
what is an Acute angle?If an angle is less than 90 degrees, then it is called an Acute angle. Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.
Given there is a right triangle. since it's a right triangle angle one angle will always be 90 degrees.
Since the sum of all angles of any triangle is 180 degrees thus,
7x + 8x + 90 = 180
15x = 90
x = 6
since each acute angles were 7x and 8x
hence those angles would be 42 and 48 degrees.
therefore, Each acute angle is 42° and 48° in size.

Solve the following expression 8 + (-20)
Answers
Answer:
-12
Step-by-step explanation:
integer rule = when a + and - comes it is indicated as - so ..
8-20 = -12
we put a minus sighnbecause 20 is the bigger number
Answer:
-12
Step-by-step explanation:
Note the rules of the signs:
If there are two positive signs next to each other, the resulting sign will be positive. Example + (+ ).
If there is one negative sign and one positive sign directly next to each other, the resulting sign will be negative Example - (+ ) or + (- ).
If there are two negative signs directly next to each other, the resulting sign will be positive. Example - (- ).
In this case, there is one negative, and one positive sign. Subtract 8 with 20:
8 + (-20) = 8 - 20 = -12
-12 is your answer.

Find x and y so that the quadrilateral is a parallelogram.
Answers
Answer:
Result:
The value of x = 12The value of y = 21Step-by-step explanation:
Given
The parallelogram DEFG
DE = 6x-12
FG = 2x+36
EF = 4y
DG = 6y-42
We know that the opposite sides of a parallelogram are equal.
As DE and FG are opposite sides, so
DE = FG
substituting DE = 6x-12 and FG = 2x+36 in the equation
6x-12 = 2x+36
6x-2x = 36+12
simplifying
4x = 48
dividing both sides by 4
4x/4 = 48/4
x = 12
Therefore,
The value of x = 12
Also, EF and DG are opposite sides, so
EF = DG
substituting EF = 4y and DG = 6y-42 in the equation
4y = 6y-42
switching sides
6y-42 = 4y
6y-4y = 42
2y = 42
dividing both sides by 2
2y/2 = 42/2
y = 21
Therefore,
The value of y = 21
Result:
The value of x = 12The value of y = 21Sam worked on his science fair project for 1/4 hour on Friday in 1/2 hour on Saturday what are the four common denominators which are less than 20 for the fractions complete exclamation

Solve the following system using the Elimination Method; 6x+y=10 and 2x+y=12.
Answers
Hey there!
The solution to the system is [tex](\frac{1}{2}, 13)[/tex]
To solve the system, we can multiply the second equation by -1:
[tex]-2x - y = -12[/tex]
Then, we add the two equations together, and solve for x:
[tex]4x = -2[/tex]
[tex]x = \frac{-1}{2}[/tex]
Now, we plug the x value into one of the equations, and solve for y:
[tex]2(\frac{1}{2} ) + y = 12[/tex]
[tex]-2 + y = 12[/tex]
[tex]y = 13[/tex]
Now we know that the solution to the system is [tex](\frac{1}{2}, 13)[/tex]
Hope it helps and have an amazing day!
Answer:
(-1/2, 13)
Step-by-step explanation:
Multiply the 2nd equation by -1, obtaining the following system:
6x + y = 10
-2x - y = -12
------------------
Combine like terms, obtaining:
6x + y = 10
-2x - y = -12
------------------
4x = -2
Dividing both sides by 4 yields x = -2/4, or x = -1/2
Substituting -1/2 for x in the second equation yields:
2(-1/2) + y = 12, or
-1 + y = 12. Then y = 13, and the solution is
(-1/2, 13)

(2 points) Part C: Solve the system from (b) by using either substitution or elimination *show all solving steps*. (4 points) Part D: Write a solution statement answering the question
Answers
Answer:
Jackie collected 61 coins and 20 stamps
Step-by-step explanation:
Solving (a): Variable representation
Let the coins be represented with c
Let the stamps be represented with s
Solving (b): Setup equation
Total is 81. This implies that:
[tex]s + c = 81[/tex]
Also:
[tex]c = 1 + 3s[/tex]
Solving (c): Solve the system
Substitute 1 + 3s for c in [tex]s + c = 81[/tex]
[tex]s + 1 + 3s = 81[/tex]
Collect Like Terms
[tex]s + 3s = 81-1[/tex]
[tex]4s= 80[/tex]
Divide both sides by 4
[tex]s = \frac{80}{4}[/tex]
[tex]s= 20[/tex]
Substitute 20 for s in [tex]c = 1 + 3s[/tex]
[tex]c = 1 + 3 * 20[/tex]
[tex]c = 1 + 60[/tex]
[tex]c = 61[/tex]
Solving (d): Solution statement

Here is an inequality 4y > 1.2 Which value of y from the { -0.5, -0.3, 0.3, .05 } makes the inequality true?
Answers
Answer:
[tex]y = 0.5[/tex]
Step-by-step explanation:
Given
[tex]4y > 1.2[/tex]
Required
Which value of y from [tex]\{ -0.5, -0.3, 0.3, 0.5 \}[/tex] makes the inequality true
First, we need to solve the inequality:
[tex]4y > 1.2[/tex]
Divide through by 4
[tex]\frac{4y}{4} > \frac{1.2}{4}[/tex]
[tex]y > \frac{1.2}{4}[/tex]
[tex]y > 0.3[/tex]
This means that the value of y that makes the inequality true is greater than 0.3.
From the list: [tex]\{ -0.5, -0.3, 0.3, 0.5 \}[/tex]
Only 0.5 is greater than 0.3.
Hence:
[tex]y = 0.5[/tex]
A company is designing a square prism. It's height is 3 yards longer than a side of its base. The volume of the prism must be 20 cubic yards. (V=l*w*h) Write a representative function for the volume of the solid
Answers
Answer:
l³+3l - 20 = 0Step-by-step explanation:
Given the volume of a prism expressed as;
V = lwh
l is the length of the prism
w is the width
h is the height of the prism
Since the prism is square based, l = w
The formula becomes
V = l²h
If its height is 3 yards longer than a side of its base, then h = l+3
V = l²(l+3)
V= l³+3l
Given V = 20yd³
The expression becomes
20 = l³+3l
l³+3l - 20 = 0
Hence the representative function for the volume of the solid is l³+3l - 20 = 0
