1. x = 31
2. y = 5 + 23
3.
4. y = -7
5. x = -2 + 13
Answer:
x = 10.5
Step-by-step explanation:
(r)=x .
y =18.8 / 2 = 9.4 .
z= 4.7
pythaoroas
r² = y²+z²
r²= (9.4)²+(4.7)²
r²= 88.36 + 22.09
√r² = √110.45
r = 10.5

Answer:
Step-by-step explanation:
If we let x represent "a number", then "three times a number" is 3x. The usm of that and 1 is ...
1 +3x . . . . . . the sum of 1 and 3 times a number
That is said to be -89, so we have the equation ...
1 +3x = -89
__
To solve this equation, we can subtract 1 from both sides:
3x = -90
Then we can divide by 3 to find x.
(3x)/3 = -90/3
x = -30
The answer is 3.45 meters and the second ones gonna be .01
Answer:
7/44
Step-by-step explanation:
you can't simply subtract 1/11 from 1/4 because the denominators are not the same . Meaning you have to convert the denominators into a similar number. Transformers in even number and a consecutive number while 11 is an odd number and a prime number they don't really agree on anything 11 can only be divided by itself and 1 wall for can be divided by a multitude of things. Because of them not exactly agreeing on any specific category , you have to multiply them by each other . So your new fractions should look like 11 / 44 and 4 / 44 . from there you can easily subtract 4 from 11 and get 7 / 44 now normally you can reduce these types of fractions but because seven can only be divided by itself and 44 is not a factor of 7 you cannot reduce this fraction .
