What is the x in this equation
14x−8=4
Answer:
x = 6 / 7
Step-by-step explanation:
Let's solve your equation step-by-step.
14 x − 8 = 4
Step 1: Add 8 to both sides.
14x − 8 + 8 = 4 + 8
14x = 12
Step 2: Divide both sides by 14.
14 x / 14 = 12 / 14
x = 6 / 7

What is the slope of the line shown on the graph?
Answer:
Step-by-step explanation:
The slope, m, can be determined using any two points, and slope is defined as
m=(y2-y1)/(x2-x1), I’ll use (0,0) and (5,-1)
m=(-1-0)/(5-0)
m=-1/5
you will explain how to go about solving for the unknown letters A B C D using your angle vocabulary /concepts. Organize your sentences in a way that clearly emphasis your understanding of this unit.
Angle vocabulary/ concepts :
Supplementary Angle
Transverse Angles
Complimentary Angle
Triangle Sum Theorem
Right Angle
Straight Angle
Vertical Angel
Congruent
Parallel Lines
Answer:
To find c° go with Triangle Sum Theorem .
To find d° go with Supplementary Angle with 58°.
To find a° go with Transverse Angles.
To find b° go with Transverse Angles .
Step-by-step explanation:
c° = 180- 58 - 48 = 74°
b° = 48°
d° = 180 - 58 = 122°
a° = 58°

12. Triangle XYZ is a right triangle. Angle Y is the right angle. If tan Z = 3/4 , then Predict the tan X. A) 4/5 B) 3/4 C) 3/5 D) 4/3
Answer:
D) 4/3
Step-by-step explanation:
12. Triangle XYZ is a right triangle. Angle Y is the right angle. If tan Z = 3/4 , then Predict the tan X. A) 4/5 B) 3/4 C) 3/5 D) 4/3
IF tan Z = 3/4
Since m<Y = 90 degrees
Let the opposite side be XY
YZ be the adjacent side
and XZ is the hypotenuse
Given
tan theta = opp/adj
opp = 3 = XY
adj = 4 = YZ
Get the hypotenuse
hyp^2 = 3^2 + 4^2
hyp^2 = 9 + 16
hyp^2 = 25
hyp = √25
hyp = 5
for tanX;
Side opposite to angle X is YZ
Adjacent side = XY = 3
opposite = YZ = 4
Tan X = YZ/XY
Tan X = 4/3
Hence the prediction of Tan X is 4/3

Use triangles to find the sum of the interior angle measures of the polygon.
Answer:
1440°
Step-by-step explanation:
From the 8 sided diagram, 8 triangles can be obtained. 1 triangle adds up to 180° thus for the diagram ,sum of interior will be 180°×8=1440°

95
2.
190
3
285
4
380
Write an equation to represent the relationship between the time, and d, the total distance traveled by the train.
Answer:
d=95t
d= 95 times the time
e.g d=95t
95=95*1
Quarters have a coating of copper mixed with nickel on the outside. If the diameter of a quarter is 24.3 mm, then what is the surface area of one side of the quarter that will get coated?
Answer: 463.96 mm² or 46.4 cm²
Step-by-step explanation:
Quarters are circular in shape so the surface area of one side will be the area of a circle.
Area of a circle = π * r²
Radius = Diameter / 2
= 24.3 / 2
= 12.15 mm
Area = 22/7 * 12.15²
= 463.96 mm²

What is the slope of the similar triangles?
Ms. Peters has 36 red, blue, and green markers. She has an equal number of
each color of marker. She arranges the red markers in 2 equal groups. How
many red markers are in each group?
18
9
6
12
Answer:
6 markers
Step-by-step explanation:
1) Find the number of red markers
Firstly, we know that Ms. Peters has a total of 36 markers. There are 3 colours within these 36 markers. Because she has an equal number of each colour, divide 36 by 3 to find the number of red markers.
36÷3=12
Therefore, Ms. Peters has 12 red markers.
2) Find the number of red markers in each group
Ms. Peters then divides the red markers into 2 equal groups. Because we now know that there are 12 red markers, divide 12 by 2 to find this number.
12÷2=6
Therefore, there are 6 red markers in each group.

−9x−6y=15
9x−10y=145
y=
x=
Answer:
Step-by-step explanation:
Adding the two equations together gives you
9x-10y-9x-6y=145+15
-16y=160
y=-10, using this value in 9x-10y=145 gives you
9x-10(-10)=145
9x+100=145
9x=45
x=5
So y=-10 and x=5

here is a formula:
a=2b-c
what is the value of a if b=12 and c=-4
Answer:
a=28
Step-by-step explanation:
a = 2b - c
a = 2(12) - (-4)
a = 24 + 4
a = 28
by the formula
a=2b-c
if b =12
so, a= 2*12-(-4)
a= 24+4
a=28
