Intersecting lines are lines that meet at some point while perpendicular lines are intersecting lines that makes a right angle at the point of intersection.
Two line can either be intersecting or perpendicular. It is not possible to have two line that is neither intersecting or parallel.
Answer:
3
Step-by-step explanation: You divide 45 and 60 then you mutiple the number by 4 then find your answer after you done solved this is how you solve it 45 divided by 60=0.75 mutiply by 4=3
I think the answer is 25 miles.
6+4+.7x= 27.50
10+.70x= 27.50
.70x= 17.50
Divide both sides by .7 and the answer is 25.
ANSWER

EXPLANATION
From the table,


There is a constant difference of


The sequence is therefore an arithmetic progression.
The general formula for the arithmetic progression is

We substitute the values into the formula to obtain,

We expand the bracket to obtain,

This simplifies to
Answer: the price of each apple is $2.25 and the price of each mango is $1.25
Step-by-step explanation:
Let x represent the price of one apple.
Let y represent the price of one mango.
Cameron went into a grocery store and bought 4 apples and 7 mangos, costing a total of $17.75. This means that
4x + 7y = 17.75 - - - - - - - - - - - - 1
Gavin went into the same grocery store and bought 2 apples and 5 mangos, costing a total of $10.75. This means that
2x + 5y = 10.75 - - - - - - - - - - - - -2
Multiplying equation 1 by 1 and equation 2 by 2, it becomes
4x + 7y = 17.75
4x + 10y = 21.5
Subtracting, it becomes
- 3y = - 3.75
y = - 3.75/ - 3
y = 1.25
Substituting y = 1.25 into equation 2, it becomes
2x + 5 × 1.25 = 10.75
2x + 6.25 = 10.75
2x = 10.75 - 6.25 = 4.5
x = 4.5/2 = 2.25
