X = -3

Pull out the like terms: -7x - 21 = -7 × ( x + 3)

Solve: -7 = 0

Solve: x + 3 = 0

Subtract 3 from both sides of the equation

So, x = -3

Step-by-step explanation:

Lets set up a proportion:

x/1096 = 5/8

Many mechanics advised people not to drive their cars more than 5,000 miles between oil changes kaci has driven her car 3450 mil

Verizon [17]

Answer:

See explanation!

Step-by-step explanation:

We know that the maximum miles allowed before oil change is 5,000miles (<u>thus Kaci can drive less or up to 5,000 miles but not more</u>).

Kaci has already driven 3,450miles since last oil change.

Inequalities are typically employed to show a relating or comparative relationship between expressions and can be identified by the sybolism of less, more or/and equal to (i.e. , $>$ , $\leq$ , $\geq$ ).

Let us denote the miles Kaci can drive before oil changing again by $x$ , then we can write the following inequality:

$3450+x\leq 5000$

solving for the remaining miles $x$ allowed

$3450+x\leq 5000\\x\leq 5000-3450\\x\leq 1550$

Thus Kaci can drive up to and including 1550 miles before chaging car oil again.

From the sum of 4a + b + c and 9a - c subtract the sum of 18a - b - c and 14a - 2b - c

sergiy2304 [10]

1:-

$\\ \rm\Rrightarrow 4a+b+c+9a-c$

$\\ \rm\Rrightarrow 4a+9a+b+c-c$

$\\ \rm\Rrightarrow 13a+b$

2:-

$\\ \rm\Rrightarrow 18a-b-c-(14a-2b-c)$

$\\ \rm\Rrightarrow 18a-b-c-14a+2b+c$

$\\ \rm\Rrightarrow 18a-14a-b+2b-c+c$

$\\ \rm\Rrightarrow 4a+b$
