Answer:
x=28
m<ACD=68°
Step-by-step explanation:
2x+(180-124)+(180-4x)=180
-2x+236=180
-2x=180-236
-2x=-56
x=28
m<ACD=180-4x=180-4(28)=180-112=68
Answer:
The answer is <ACD = 68°
Step-by-step explanation:
Using the property that the sum of interior angles in a triangle is equal 180°,we have:
<DAC + <ACD + <ADC = 180°
[tex]2x + (180 - 4x) + 56 = 180 \\ - 2x + 56 = 0 \\ 2x = 56 \\ x = \frac{56}{2 } \\ x = 28[/tex]
Finally, calculating the angle <ACD, we have:
<ACD = 180 - 4x
<ACD = 180 - 4 . 28
<ACD = 180 - 112
ACD = 68°

C.
Step-by-step explanation:
The difference of two numbers is 3. Their sum is 13. Write a pair of simultaneous equations in x and y to represent this information.
Answer:
x-y=3
x+y=13
2x=16
x=16/2
x=8
x+y=13
8+y=13
y=13-8
y=5
Answer:
x + y = 13
x - 3 = y
or
x + y = 13
y - 3 = x

Answer:
1402 tiles
Step-by-step explanation:
so in order to find the amount of glass tiles we will first need to find the surface area of the box
so the surface area formula for a rectangular prism is
2 (wl * hw* hl)
w- width
h- height
l- length
so the width would be 18centimeters
the height would be 7 cm
and the length would be 23 cm
therefore if we plug in the measurements into the equation it will give us a total surface area of
1402cm^2
therefore if Dimitri wants to cover the box with 1cm glass tiles then we take the 1402cm and divide it by 1cm leaving us with the same answer of
1402 tiles
6 - 2y + (-8y) + 5.1 = 0
(Simplify your answer. Use integers
Answer:
Simplified answer = 11.1 - 10y = 0
y = 1.11
Step-by-step explanation:
6 - 2y + (-8y) + 5.1 = 0
6 + 5.1 -2y -8y = 0
Add like terms
11.1 - 10y = 0
(This is simplified, but if you want to solve for y, continue)
11.1 - 10y = 0
÷10 ÷10
1.11 - y = 0
y = 1.11 because 1.11 - 1.11 is 0
