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.

False, because any number multiplied by a number lower than 1 will always be less than the original number

Length 21cm area 315cm2 find the breath ​
Ronch [10]

Answer:

Breadth = 15 cm

Step-by-step explanation:

Area = length x breadth

315 = 21 x breadth

\frac{315}{21} = \frac{21}{21} \times breadth                 [ dividing both sides by 21 ]

15 = 1 \times breadth\\\\breadth = 15 \ cm
