Solve for the indicated variable in the literal equation ​
ANTONII [103]

Answer:

x = \frac{y}{3} - \frac{5}{3}

Step-by-step explanation:

Given

y = 5 + 3x

Required

Solve for x

Subtract 5 from both sides

y-5 = 5 -5+ 3x

y-5 = 3x

Divide through by 3

\frac{y}{3} - \frac{5}{3} = x

x = \frac{y}{3} - \frac{5}{3}

Please solve, thank you (and show steps):<br><br>Solve for x:<br><br>5x + 22 = 27​
IrinaVladis [17]
Given the equation, 5x + 22 = 27:

The goal is to isolate the variable. Hence, a few mathematical operations are necessary to solve for the value of x.

Start by subtracting 22 both sides:
5x + 22 - 22 = 27 - 22
5x + 0 = 5
5x = 5


Next, divide both sides by 5 to isolate and solve for the value of x:

5x/5 = 5/5

x = 1

In order to verify whether x = 1 satisfies the give equation, we must substitute its value into the given equation:

5x + 22 = 27

5(1) + 22 = 27
5 + 22 = 27
27 = 27 (True statement. This implies that x = 1 is the correct value that satisfies the equation).

Therefore, the correct answer is x = 1.

Given the following sequence, find the 23rd term: 10.5, 11, 11.5, 12, 12.5, . . .
4vir4ik [10]
10.5, 11, 11.5, 12, 12.5...this is an arithmetic sequence with a common difference of 0.5

an = a1 + (n - 1) * d
n = term to find = 23
a1 = first term = 10.5
d = common difference = 0.5

sub and solve

a(23) = 10.5 + (23 - 1) * 0.5
a(23) = 10.5 + 22 * 0.5
a(23) = 10.5 + 11
a(23) = 21.5 <===
