Answer:
<em>t = 540</em>
Step-by-step explanation:
18 - t/20 = -9
Subtract 18 from both sides.
-t/20 = -27
Multiply both sides by -20.
t = 540
The LCD is 6 on the left and 9 on the right.
Answer:
measurement of the indicated angle is 59°
Step-by-step explanation:
20x - 19 + 8x + 3 = 180
28x - 16 = 180
+16 +16
----------------------------------
28x = 196

x = 7
8 (7) + 3 = 59
20 (7) - 19 = 121
Answer:
Part A is 5/6 of the whole
Part B is 1/6 of the whole
Solution:
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 15 + 3 = 18
Part A = 15 and Part B = 3 are numerators for each fraction.
The fractions are then:
15/18 and 3/18
Meaning:
Part A is 15/18 of the whole
Part B is 3/18 of the whole
Reducing the fractions, it is also true that:
Part A = 5/6 of the whole
Part B = 1/6 of the whole
Width of the rectangle is 10 m
<u>Step-by-step explanation:</u>
Step 1:
Let the width of the rectangle be x. Then length of the rectangle will be 8 + 6x. Perimeter = 156m
Perimeter of a rectangle = 2 (length + width)
⇒ 156 = 2 (8 + 6x + x)
⇒ 156 = 16 + 14x
⇒ 140 = 14x
∴ x = 140/14 = 10 m
⇒ Width of the rectangle is 10 m
