Which choice describes an equation

Mathematics
1 answer:
Sladkaya [172]2 years ago
6 0

Answer:

Step-by-step explanation:

Remark

Choose any number at all and see what happens.

Suppose x = 8

3*(8 + 1) = 3*8 + 3

3(9) = 27

3*8 + 3 = 24 + 3 = 27

What you have shown is that the second choice is incorrect. There is at least one value that makes the equation correct (that is, both sides come to the same result.)

If choice two is false then choice one must be true since these results may give the only 2 possible results.

Answer:

278.2 \: ft

Step-by-step explanation:

Descended feet:

94 \: s \times 3.3 \:  \frac{ft}{s} \:  = 310.2 \: ft

Ascended feet:

32 \: s \times 1 \:  \frac{ft}{s}  = 32 \: ft

Total elevation:

(310.2 - 32) \: ft = 278.2 \: ft

When all sides of a quadrilateral are equal (indicated by tick marks on the four sides) in length and connect the opposing vertices with a line, it will form four 90° angles. Therefore, each equation will equal 90.

10x= 90

x+y= 90

3z= 90

The measure of angles 1 and 3 can be solved as they are so:

10x= 90 ➡️ x=9

3z= 90 ➡️ z= 30

The value of x is needed to solve for the measure of angle 2 so plug in the value of x and solve:

x+y= 90

9+y= 90

y= 81

Therefore the answer is a.
