False.
The most important job is to promote the material. For example, Ads don't always promise what they tell you, but they make the product seem very desirable.
Let us take the second equation first
2a + 2b = 6
Dividing both sides by 2 we get
a + b = 3
a = 3 - b
Putting the value of a in the first equation we get
3a + 4b = 9
3(3 - b) + 4b = 9
9 - 3b + 4b = 9
b = 9 - 9
= 0
Now putting the value of b in the second equation we get
a + b = 3
a + 0 = 3
a = 3
So the value of the unknown variable a is 3 and the value of the unknown variable b is 0.

The distance covered by bicycle is 1.885 km.
What is distnace?
Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in ordinary language.
Given: A bicycle wheel with radius 30cm made 1000 revolutions.
We have to find the total distance covered by bicycle.
First to find the circumference of the bicycle wheel.
Circumference = 2πr
where, r is the radius.
Here r = 30.
So,
Circumference = 2 x π x 30 = 60π
Now to find the total distance,
D = circumference x number of revolutions.
D = 60π x 1000
D = 188,495.5592 cm
D = 188,495.5592 /1000 km
D = 1.88 km
Therefore, the distance covered by bicycle is, 1.885 km.

Answer:
the length of the opposite side (x), is 27.2
Step-by-step explanation:
For the given right triangle problem;
the opposite side of the given angle, opp. = 22
the hypothenuse side, hypo. = x
given angle of the triangle, θ = 54⁰
The length of the opposite side (x), is calculated as follows;
Therefore, the length of the opposite side (x), is 27.2
