Answer:
78°
Step-by-step explanation:
(I'm assuming that segment AB is a straight line {180 degrees})
1. since angles DCA and DCB equals 180°, we can set up the equation 4x+2+3x+3=180.
2. if you solve that, you'll get x=25.
3. plug 25 (x) into 3x+3 -> 3(25)+3
4. 3(25)+3=78
5. answer: 78°

Answer:
the equation of the line is y = -1/-30 - 3⅙ and the y intercept is -3⅙.
Step-by-step explanation:
Using, the formula y1+y2/x1-x2,
Choosing any two points, make the expression:
1-2/125-155
simplify:
-1/-30
the slope of the equation is -1/-30.
to find y intercept, using the function y=mx+b, plug in the slope and one of the two points that you used:
y would be 2
x would be 155
b is the y intercept
2= -1/-30•155 + b
2=5⅙+b
b = - 3⅙
the equation of the line is y = -1/-30 - 3⅙ and the y intercept is -3⅙.

Unit conversion can be defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
To convert centimeters to inches, we have to use the conversion factor 1 inch = 2.54 cm.
To determine how many inches are in 2540 cm, first we divide 2540 by 2.54:
2540 cm ÷ 2.54 = 1000 inches
Therefore, we can conclude that 2540 centimeters are equal to 1000 inches.

What is 37 divided by 4
Answers
Answer:
9.25
Step-by-step explanation:
The quotient of 37 divided by 4 is 9 with a remainder of 2, or written as a mixed number, it is 9 2/4 or 9 1/2.
To solve 37 divided by 4 step by step:
Step 1: Divide the first digit of the dividend (37) by the divisor (4):
37 ÷ 4 = 9
Step 2: Multiply the quotient (9) by the divisor (4) to get the product:
9 × 4 = 36
Step 3: Subtract the product (36) from the dividend (37) to find the remainder:
37 - 36 = 1
Step 4: Bring down the next digit (0) from the dividend to the remainder:
Remainder: 10
Step 5: Divide the new number (10) by the divisor (4):
10 ÷ 4 = 2
Step 6: Multiply the new quotient (2) by the divisor (4) to get the product:
2 × 4 = 8
Step 7: Subtract the product (8) from the remainder (10) to find the new remainder:
10 - 8 = 2
Step 8: Since the remainder (2) is less than the divisor (4), we can stop here.
Therefore, the quotient of 37 divided by 4 is 9 with a remainder of 2, or written as a mixed number, it is 9 2/4 or 9 1/2.
