Answer:
8 4/15
Step-by-step explanation:
Rewriting our equation with parts separated
= 5 + 2/3 + 2 + 3/5
Solving the whole number parts
5 + 2 = 7
Solving the fraction parts
2/3 + 3/5 = ?
Find the LCD of 2/3 and 3/5 and rewrite to solve with the equivalent fractions.
LCD = 15
10/15 + 9/15 = 19/15
Simplifying the fraction part, 19/15,
19/15 = 1 4/15
Combining the whole and fraction parts
7 + 1 + 4/15 = 8 4/15
5x^7 , Y^11 is your answer
Answer:

Step-by-step explanation:
<h2>Given that :</h2>
- The radius of a circle is 2.9 in.
<h2>to find :</h2>
- Find the circumference to the nearest tenth.
<h2>formulas used :</h2>
- circumference = 2 × π × r
where,
<h2>explanation :</h2>
⟼ c = 2πr
⟼ c = 2 × 22/7 × 2•9 inches
⟼ c = 2 × 3•14 × 2•9 inches
⟼ c = 6•28 × 2•9 inches
⟼ c = 18•21 inches.
<h2>Round to the nearest tenth :</h2>
⟼ c = 18•21 inches
⟼ c = 20 inches
∴ circle circumference is 20 inches .
Step-by-step explanation:
-7(1+3x) = 4 + 5x
-7 - 21x = 4 + 5x
(get all the variables on one side. Don't forget to change the signs)
-7-4 = 5x + 21x
-11 = 26x
(divide both sides by the coefficient [26])
26x/26= -11/26
x = -11/26
