Answer:

-x-3

Step-by-step explanation:

First, you need to distribute the 1/5 to both the term 5x and the term -15, which requires multiplication. This gives you 1x-3. The -2x can then be added on to this equation, which gives you 1x-3-2x. Combining the like terms of 1x and -2x gives you -x. The entire expression is then -x-3.

3. Find the measure of x.<br> a 18°<br> b. 54°<br> C 126<br> d. 45

Nataliya [291]

Answer:

18 degrees

Step-by-step explanation:

The triangle is an iscoceles right triangle.

The angles in a triangle add up to 180.

90+2y (iscoceles) =180

2y=90

y=45

So the angles of the right triangle are 45. However, you have to take away 27 because you are solving for only a part of 45. 45-27=18

Solve for x in the given equation: ax - b = c

lord [1]

An equation is formed of two equal expressions. The value of x is the equation ax-b=c is (c+b)/(a).

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

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution of x in the given equation can be written as,

$ax - b = c\\\\ax = c+b\\\\x = \dfrac{c+b}{a}$

Hence, the value of x is the equation ax-b=c is (c+b)/(a).
