Answer:
The equation: 2<em>n</em> - 3 ≤ -21
The answer to the equation: <em>n</em> ≤ 9
Step-by-step explanation:
How to get the equation:
<u>The difference of</u> symbolizes subtraction. Because we are subtracting twice a number and 3, the first part of the equation can be written as 2<em>n</em> - 3. The <em>n</em> symbolizes the number.
<u>is at most</u> symbolizes a less than or equal to sign. That sign is ≤. And what is it less than or equal to? -21.
Now are equation is 2<em>n</em> - 3 ≤ -21
How to solve it:
2<em>n</em> - 3 ≤ -21
Add 3 to both sides of the equation
2<em>n</em> ≤ 18
Divide both sides of the equation by 2
<em>n</em> ≤ 9
Answer : 2604 can be divided into 1736 and 868 in the ratio of 2:1.
Step-by-step explanation:
2x + x = 2604
or, 3x = 2604
or, x = 2604/3 = 868
so
2x = 2*868 = 1736
now
x = 868

Answer:
i think probably 80°
Step-by-step explanation:
PQ = RS
2x+3 = 4x-3
x = 3
PTQ = RTS
9y-3x-1 = 5x+7y-5
2y-8x = -4
y-4x = -2
y-4(3) = -2
y-12 = -2
y = -2+12
y = 10
so PTQ = 9y-3x-1
9(10)-3(3)-1
90-9-1
80°
