Answer:

x = 23

Step-by-step explanation:

The 38 degree angle and the (6x +4) angle are supplementary which means both have to add up to 180 degrees. 180 - 38 leaves us with 142. When you plug in 23 to x you get (6(23) + 4) 6 times 23 is 138 and 138 plus 4 is 142. Which gives us our answer of x = 23.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Last year, Andrea's annual salary was A dollar and she was paid biweekly. This year she received a raise of R dollars per year. She is now paid semimonthly.

Biweekly salary last year algebraically will be:-

S = (27)A.

Semimonthly salary this year algebraically will be:-

S = ( A + R )6.

Therefore, the biweekly salary last year algebraically will be S = (27)A. Semimonthly salary this year algebraically will be S = ( A + R )6.

Rashid [163]

Marcus needs to bike at least 11 miles each day.

Step-by-step explanation:

Given,

Distance to cover = 80 miles at least

Distance already biked = 25 miles

Number of days left = 5

Let,

x be the distance to cover in 5 days.

According to given statement;

Number of days left * Distance to cover + distance already bike ≥ Total distance to travel

$5x+25\geq 80\\5x+25-25\geq 80-25\\5x\geq 55$

Dividing both sides by 5

$\frac{5x}{5}\geq \frac{55}{5}\\x\geq 11$

Marcus needs to bike at least 11 miles each day.
