Answer:
x=9
Step-by-step explanation:
Since ABCD is a square, we know that AC bisects ∠BCD(=90), and therefore ∠ACB=45.
8x-27=45
8x=72
x=9
Answer:
x = 9°
Step-by-step explanation:
∠ACB = 45° because line AC bisects ∠BCD which is 90° (because square).
8x - 27° = 45°
add 27° to each side:
8x = 72°
divide both sides by 8:
x = 9°

−9x−6y=15
9x−10y=145
y=
x=
Answers
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

14x−8=4
Answers
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

Sara picked 18 to 24 roses she divided flowers into groups so that the same number of tulips and roses were in each bouquet. What is the greatest number of bouquets she could have
Answers
Answer:
6 bouquet
Step-by-step explanation:
To obtain the greatest number of bouquet she could have ;
Obtain the greatest common factor of 18 and 24
Factors of 18 : 1 , 2, 3, 6, 9, 18
Factors of 24 : 1, 2, 3, 4, 6, 8, 12, 24
The greatest factor commo to both 18 and 24 is 6.
Hence, the greatest number of bouquet she could have is 6.
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
Answers
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.
I hope this helps!
here is a formula:
a=2b-c
what is the value of a if b=12 and c=-4
Answers
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

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?
Answers
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

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
