Answer:

18 and 20, 4

Step-by-step explanation:

Math reasoning 1:

Set the first number as x and the other one as x+2 because it is a consecutive even number.

x+x+2=38

2x=36

x=18

18+2=20

The 2 consecutive numbers are 18 and 20

Problem solving 1:

Write out equation first, set the unknown number as x

5+x=9

x=4

Simplify

Scorpion4ik [409]

Answer:

Step-by-step explanation:

using the rule of exponents

$(\frac{a}{b}) ^{-1}$ = $\frac{b}{a}$ , then

$\frac{123}{321}$ × $\frac{456}{654}$ × $\frac{789}{987}$ × $\frac{321}{123}$ × $\frac{654}{456}$ × $\frac{987}{789}$

[ $\frac{123}{321}$ × $\frac{321}{123}$ = 1 , $\frac{456}{654}$ × $\frac{654}{456}$ = 1 , $\frac{789}{987}$ × $\frac{987}{789}$ = 1 ]

= 1 × 1 × 1

= 1

Adelaide paid $35 for a manicure and gave the manicurist a 20% tip How much money did Adelaide give her manicurist

seropon [69]

The correct answer is:
$42.

Explanation:
The best way to find a total bill including tip (or tax if that is what you are looking for - it is found the same way), is to multiply the original total by 1 + the percentage of the tip.

Since the percentage is 20%, we add 0.20 to 1 to get 1.20.
Now we multiply that by the original cost to get the final answer.
1.20*35 = 42
