Answer:
The proposed equation is solved as follows:
2X + 7 = 21
2X = 21 - 7
2X = 14
X = 14 / 2
X = 7
The value of X is 7.
A first degree equation is an algebraic equation in which each term is either a constant or a product of a fixed term on a single variable. Therefore, this equation is a first degree one, since it only has a single variable, which is X.
Answer:32.1428571429 feet
Step-by-step explanation:
The flag is 15 feet.
It's shadow is 10.5 feet.
15/10.5=1.4285714286.
So the flag is above mentioned times of the shadow.
And the tree's hight will be,
22.5*1.4285714286
=32.1428571429 feet.
[4.6+2×(5_2)]÷2=7
4.6+2=4.8
4.8×5=240
240_2=238
238÷2=116
It would be 64 because x equals 2. Y=3
