7. We know that they must all add up together to get 90 degrees because of the symbol show the right angle. 
We can use this to form and solve an equation:
2x +1x + 30 = 90
3x+30 = 90  (add the x's together)
3x = 60    (subtract both sides by 30 to get the x's alone)
x =20  (divide by 3 to get what 1x is equal to)

(The next question is very similar)
8. To solve this, we need to know what all the x's together are equal to.
Since angles on a straight line add up to 180 degrees -we can make an equation:
4x+x+30 = 180 
5x + 30 +180  (add all the x's together)
5x = 150  (subtract both sides by 30 to get what 5x is equal to)
x = 30 (divide by 5 to get what just 1x is)

Hoped this helped - please ask if anything doesn't make sense!

Write that as 7x.  Writing it as x7 could lead to confusion.  7*x would be OK.

saveliy_v [14]

19770609664 is simple power of 52⁶ .

What is exponent and power?

  • A base number raised to an exponent is referred to as a power in mathematics, where base number is the factor that is multiplied by itself and exponent is the number of times the same base number is multiplied.
  • Exponents and powers are two techniques for simplification of extremely big or extremely small numbers.
  • As an illustration, we can write 3 x 3 x 3 x 3 as 34, where 4 is the exponent and 3 is the base, if we need to represent it simply.
  • It is claimed that the entire statement 34 has power.

= 52⁶

= 52 × 52 × 52 × 52  × 52 × 52

=  19770609664
