Answer:
That is an improper fraction
Step-by-step explanation:
When the numerator (the top) is greater than the denominator (The bottom) then the fraction is improper

Let P = 10x + y
Let Q = 10y + x
Solve
P - Q = 54 Substitute in for x and y
10x + y - 10y - x = 54
9x - 9y = 54 Divide the entire equation by 9
x - y = 6
Start by letting x = 9
9 - y = 6 Subtract 9 from both sides.
-y = 6 - 9
-y = - 3
y = 3
Therefore P is 93 <<<< Answer
Check
93 - 39 = 54 which checks.
Answer: 4
Step-by-step explanation:
so first 18+6 = 24
3 x 2= 6
24 divided by 6
is 4
The problem asks:
what is 2y+7 when y=-3?
Since y=-3 then 2y+7=2(-3)+7=-6+7=1.
Similarly, when y=-3, -4y − 10=<span>-4(-3) − 10=12-10=2.
Answer:
</span><span>2y + 7=1
-4y − 10=2</span>
Answer:
In ΔPQR, x = 25 , ∠P = 45° and ∠R = 90°
Step-by-step explanation:
Here, In ΔPQR,
∠P = x°, ∠Q = 45° and ∠R = (x + 45)°
by ANGLE SUM PROPERTY of a triangle:
Sum of all interior angles in any given triangle is always 180°.
⇒ In ΔPQR,
∠P + ∠Q + ∠R = 180°
or, x+ 45° + (x + 45)° = 180°
⇒ 2x + 90° = 180°
or, 2x = 180° - 90° = 90°
⇒ x = 90/ 2 = 45
or, x = 45
Hence, ∠P = x = 45°
and ∠R = (x + 45)° = (45 + 45)° = 90°
