3-(s+4)
less than- subtract
sum- addition
since it said 3 less than the sum of a number and 4 that means you would have to add s and 4
Answer:
A 2:3
Step-by-step explanation:
6y:9y
We can divide the ratio by 3y on both sides, since 3y goes into both numbers
6y/3y: 9y/3y
2: 3
Answer:
A
Step-by-step explanation:
Subtract 1 from both sides and divide by 2. This will leave you with x=-2 which is the simplified form of the equation.
The correct answer is: Option (D) x = 72°
Explanation:
When two lines are crossed by another line, the angles in matching corners are called <em>corresponding angles</em>. When the two lines are <em>parallel</em>, the corresponding angles are <em>equal</em>.
Here in this case, the two lines are "AB" and "CD", and both are parallel and are crossed by the line; therefore, <em>the corresponding angles will be the same</em>.
Since the first corresponding angle is 72°, the second angle <em>x </em>will be 72° as well. The correct answer is: x = 72° Option (D).
This is one half of a simultaneous equation. Without the other half, the values are theoretically unsolvable.
With that said, with trial and error you can work this out. I came out with an answer of x=1, y=12.
This is not a good practice. It's time consuming to solve simultaneous questions like this. Make sure you use the other half of the equation in the future.
I hope this helps!
