The quadrilateral have equal opposite sides, for example:
Then, (4x + 6) must be equal to (7x - 3), and (4y - 3) is equal to (3y + 1), therefore

We can solve that equation for x

Hence, x = 3. Now let's solve the other equation

Then the value of y is 4.
Final answers:
x = 3
y = 4
Answer:
The distance in one sweep is 100 cm approximately
Step-by-step explanation:
Here, we want to calculate the distance the wiper covers in one sweep
Mathematically;
we have a structure like an arc of a circle. It is the length of this arc we want to calculate.
The formula for the length of an arc is;
theta/360 * 2 * pi * r
r is the radius which in this case is 50 cm
We have ;
115/360 * 2 * 3.1412 * 50 = 100 cm approximately
Answer:
answer : B
Step-by-step explanation:
( x + 7) (3x -2) = 3x² - 2x +21x -14
( x + 7) (3x -2) = 3x²+19x -14
Answer:
70 -20x = 60 -15x
Step-by-step explanation:
The amount of money left on Josh's card is ...
70 -20x
The amount of money left on Jessica's card is ...
60 -15x
These amounts are the same when ...
70 -20x = 60 -15x
_____
<em>Additional comment</em>
The solution to this equation is ...
10 = 5x ⇒ x = 2 . . same amount after purchase of 2 pizzas
