Answer:
x = 45
y = 20
Step-by-step explanation:
Set the x-variables and y-variables with its corresponding ones, like so:
4x - 35 = 3x + 10
Subtract 3x from both sides:
x - 35 = 10
Add 35 to both sides:
x = 45
Solving for y:
2y - 5 = y + 15
Subtract y from both sides:
y - 5 = 15
Add 5 to both sides:
y = 20
Answer:
By vertically opposite angle
2y-5=y+15
y=20°
4x-35=3x+10
x=45°

Answers
Answer:∠M in the pre-image corresponds to ∠B in the image.
Step-by-step explanation:
When we look at the figures , we can see that the three vertices B , C , D are one side as vertices to M , N ,O .
Clearly , vertex C corresponds to vertex N ( presents in the middle )
Also, point B is at the right from point C .In Figure L M N O P , vertex M is at the right from vertex N .Thus , vertex M corresponds the vertex B.
It means ∠M in the pre-image corresponds to ∠B in the image.

Find the solutions to the Quadratic equation.
Answers
Answer:
x=-3
Step-by-step explanation:
(4)(2) + 4x = -4
multiply the 4 and 2
8 + 4x = -4
subtract 8 from both sides
4x = -12
divide both sides by 4
x = -3
Answer:
x = 1/2
Step-by-step explanation:
Step 1: Isolate x's
4x² - 4x + 1 = 0
Step 2: GCF
4(x² - x + 1/4) = 0
x² - x + 1/4 = 0
Step 3: Factor
(x - 1/2)² = 0
Step 4: Solve
√(x - 1/2)² = √0
x - 1/2 = 0
x = 1/2
And we have our final answer!

Which is a solution to 2x + 1 = 21?
Answers
Answer:
x = 10 is your answer
- Explain -
Step 1: subtract 1 from both sides (subtraction of equality)
which will give us:
2x = 21 - 1
which equals to
2x = 20
Step 2: Divide both sides by 2
which is
2x/2 = 20/2
2/2 = 1 and 20/2 = 10
Therefore the answer is x = 10

What is the solution of the inequality shown
below?
c+2 < -1
Answers
Answer: c < -3
Step-by-step explanation: To solve for c in this inequality, your goal is the same as it would be you were solving an equation, to get c by itself on one side of the inequality.
Since 2 is being added to c, subtract
2 from both sides of the inequality.
On the left, the +2 and -2 cancel out
and on the right, -1 - 2 is -3.
So we end up with c < -3.

(3x+20)=(5x-16) Find the value of X
Answers
Answer:
x = 18
Step-by-step explanation:
3x + 20 = 5x - 16
Subtract 20 from both sides
3x + 20 - 20 = 5x - 16 -20
3x = 5x -36 {Now subtract 5x from both sides}
3x - 5x = 5x - 36 +5x
-2x = -36 {Divide both sides by (-2)}
-2x/-2 = -36/-2
x = 18
Step-by-step explanation:
(3x+20)=(5x-16)
combination of like terms
3x-5x= -16-20
-2x= -36
x= -36/-2
x=18

What is the surface area of the rectangular prism?
Answers
Answer:
A = 348
Step-by-step explanation:
The formula for finding the surface area of a rectangular prism is:
A = 2(wl + hl + hw)
Plug in the numbers accordingly:
A = 2(6 · 9 + 8 · 9 + 8 · 6)
A = 2(54 + 72 + 48)
A = 2(174)

Answer:

Step-by-step explanation:
To find the length of each side of the square ABCD, find the length of AB.
Refer to the picture attached.
AB= AX +XB
Let's find the length AX first.
(see triangle AXY)
Applying Pythagoras' Theorem,
(AX)² + (XY)² = (AY)²
(AX)² +12²= 13² (subst. known values)
(AX)²= 169 -144 (move constant to 1 side)
(AX)²= 25 (simplify)
AX= √25 (square root both sides)
AX= 5 units
Now, let's find the length of XB.
(see triangle BXY)
Applying Pythagoras' Theorem,
(XB)² + (XY)²= (BY)²
(XB)² +12²= 15²
(XB)²= 225 -144 (bring constant to 1 side)
(XB)²= 81 (simplify)
XB= √81 (square root both sides)
XB= 9 units
AB
= 5+9
= 14 units
Therefore, length of each side of square ABCD= 14 units
To find the diagonal of the square, focus on the red shaded triangle (refer to picture 1).
Since squares have equal sides, AD= DC= 14 units
Applying Pythagoras' Theorem,
(AC)²= (AD)² +(DC)²
(AC)²= 14² +14² (subst. known values)
AC= √392 (simplify)
AC= 19.8 units (to 3 s.f.)

-10x-6y=0
-4x-6y=54
Should be an answer like 0,0
Answers
Answer:
(9, -15)
Step-by-step explanation:
First, label the 2 equations:
-10x -6y= 0 -----(1)
-4x -6y= 54 -----(2)
(2) -(1):
(-4x -6y) -(-10x-6y)= 54 -0
-4x -6y -(-10x) -(-6y)= 54 (expand, simplify)
-4x -6y +10x +6y= 54 (expand)
10x -4x= 54 (simplify)
6x= 54
x=54 ÷6
x= 9
susbt. x=9 into (1):
-10(9) -6y=0 (subst. x=9 into -10x-6y=0)
-90= 6y (bring y term to the other side)
6y= -90
y= -90 ÷6
y= -15
Thus, the solution is (9, -15).
The value of X is 9.
The value of y is -15.
