<h2>Answer:</h2>

$\boxed{x=-\frac{151}{23}}$

<h2>Step-by-step explanation:</h2>

This is an equation whose target variable is $x$ . Recall that in mathematics, an equation is a statement that involves the equality of two expression. In this case, we have the following equation:

$23(x+7)=10$

Applying distributive property:

$23x+161=10$

Subtracting 161 from both sides:

$23x+161-161=10-161 \\ \\ 23x=-151$

Dividing both sides by 23:

$\boxed{x=-\frac{151}{23}}$

The governor of state A earns 50, 440 more than the governor of state B. If the total of their salaries is $283,910, can you fin

WITCHER [35]

Use what we know to make equations in order to solve for each governor's salary.
A=governor of state A
B=governor of state B
A+b=283,910. (Their salaries combined)
A=B+50,440 (A earns 50,440 more than B)
Sub A into the original formula to solve for B
B+50,440+b=283,910
2B=283,910-50,440
2B=233,470
B=116,730
Sub B into the formula that's equal to A
A=B+50,440
A=116,735+50,440
A=167,175

A n =−1+3(n−1) an=−1+3(n−1) what is the 55 term in the sequence

Sindrei [870]

ANSWER

$a_{55}=161$

EXPLANATION

The general term for the sequence is

$a_n=-1+3(n-1)$

To find the 55th term, we have to substitute
$n = 55$
in to the general term and simplify.

This implies that,

$a_{55}=-1+3(55-1)$

$a_{55}=-1+3(54)$

$a_{55}=-1+162$

$a_{55}=161$

Therefore the 55th term is 161.

A line passes through the point (2, 10) and has a y-intercept of 4. What is the equation of the line? Help me please

joja [24]

Step-by-step explanation:

If it's a straight line the use formula

$y = mx + c$

m= gradient of line

c = y-intercept

we know that y-intercept is 4 so coordinate is

(0,4)

Equation also passes (2,10)

Use both coordinate to find gradient

m= vertical distance / horizontal distance

= (10-4) / (2-0)

= 3

y = 3x + 4
