Answer:
y=4
x= 3/7
Step-by-step explanation:
2y=8
Divide both sides by 2
2y÷2=8÷2
A.) y=4
Substitute 4 for y
7x−2y=−5
7x+(−2)(4)=−5
Simplify both sides of the equation.
7x−8=−5
Add 8 to both sides
7x−8+8=−5+8
7x=3
Divide both sides by 7
7x÷7= 3÷7
x= <u>3</u>
7
Answer:
a
Step-by-satep explanation:
1. 1 and -1 are two such rational numbers whose multiplicative inverse is same as they are.
2. absolute value is resembled using the formula : |x|
Here,


final answer: 3/11
3.



4.
Associative property can only be used with addition and multiplication
Answer:
First angle is 45 and the second angle is 60
Step-by-step explanation:
150 + 105 = 255
360 - 255 = 105
the ratio is 3:4 I add the ratio so 7
105 / 7 = 15
The first angle with the ratio of 3 is 15 x 3 = 45
The second angle with the ratio of 4 is 4 x 15 = 60
It would be zero because x can’t be less or more in this particular situation.
