What's 7 to 5 = 14 to x

What's 7 to 5 = 14 to x

The answer is x equals 10

14. How to solve the unknown if x plus 36 equals 148?
How to solve the problem that 70 minus 2 and x equals 30 and 16 minus 670 and x equals 994

14x+36=148
14x=148-36
14x=112
x=112÷14
x=8
70-2x=30
2x=70-30
2x=40
x=40÷2
x=20
16x-670=994
16x=994+670
16x=1664
x=1664÷16
x=104

X is an unknown number! For example, if x is equal to 15, how much is x

For example, X is equal to 15: you mean x is the second root;
Then x equals the square of 15, that is 15 * 15 = 225;
If the third root is equal to 15;
So this number is 15 * 15 * 15;

10×（2-X)-9×(2-X)-7×(2-X)=56

(10-9-7)(2-x)=56
-6(2-x)=56
2-x =-28/3
x =2+28/3
x =34/3

If (x + Y-7) ^ 2 + | x ^ 2-y ^ 2-56 | = 0, then the value of X-Y is________

28

7 / 8X1 / 14 = 5 / 12 divided by 5 = 9 divided by 3 / 4 = 10 divided by 2 = 56 divided by 2 / 3=

7 / 8X1 / 14 = 1 / 16, 5 / 12 divided by 5 = 1 / 12, 9 divided by 3 / 4 = 2, 10 divided by 2 = 5, 56 divided by 2 / 3 = 84

What are the stems and leaves of plants (20:59:56)
 

The embryo consists of four parts: embryo, hypocotyl, radicle and cotyledon. (1) the embryo is located at the top of the embryo, which is the primordial body of the stem leaf system of the future plant, and will develop into the aboveground part of the plant in the future. (2) the hypocotyl is located between the embryo and the radicle, and is connected with the cotyledon, and later forms the part connected with the rhizome, The growth of the hypocotyl is very helpful for the cotyledons of some seeds to be unearthed. (3) the radicle is located under the hypocotyl and provides nutrition for the embryo. It is the rudiment of the main root in the seed, which can develop into the main root of the plant and form the root system of the plant in the future. (4) the cotyledons are the leaves of the embryo, or temporary leaves, generally one or two, which are located on the side of the hypocotyl, The embryo of gymnosperms has many cotyledons. For example, Pinus has 3-18 cotyledons, which provide nutrition for the seeds without endosperm or transport nutrition for the seeds with endosperm

If you put a few barrels of water in the vegetable cellar in winter in the north, you can make use of the fact that the water needs to be hot at () to keep the temperature of the air in the vegetable cellar from () and keep the vegetables from freezing

Too low solidification heat release
It can be thought according to the principle of specific heat capacity
Because water has a large specific heat capacity
According to q = cm (t0-t)
When water of the same mass is placed in it with other liquids
More heat is released
So use water

(1) According to the speed formula v = s / T, from the topic meaning, v = s / T = 5.6 km / (15.5-15.3 hours) = 28 km / h, 28 km / h = 7.8 M / s. The average speed of a taxi during this period is 7.8 M / S (2). It also receives gravity, friction and the supporting force of the ground on the taxi
