Answer:
y = -7
Step-by-step explanation:
-3x – 2y = -25
Let x = 13
-3 * 13 -2y = -25
-39 -2y = -25
Add 39 to each side
-39+39 -2y = -25+39
-2y =14
Divide by -2
-2y/-2 = 14/-2
y = -7
Answer:
2. 3-(-2)-(+5)
⇒3-(-2)-(+5)= 3+2-(+5) = 5-(+5) = 5-5 = <u>0</u>
3. -(-3-6)-(-4+8)
⇒ -(-9)-(-4+8) = 9-(-4+8) = 9-4 =5
4. -8-(-3-2)
⇒ -8-5=-13
5. -(-(-5))+7
⇒ -5+7 = 2
6. -(-(-8)+3)
⇒ -(11) = -11
7. -(-6-(-3+1))
⇒6-(-3+1) = 8
8. 1-(14-(11-7))
⇒ 1-(14-4) = 1-10 = -9
Answer:
x = 14

The diagram is shown in the picture. The real numbers are divided into rational numbers and irrational numbers. Example of a rational number is any fraction like 1/2, while an irrational number is one that cannot be expressed as a fraction like π. Then, integers are also part of the rational numbers which include positive and negative whole number like -5, and +4. Whole numbers are positive numbers from 0 to whatever number. Lastly, the natural numbers are whole numbers with the exception of zero. So, these are numbers from 1 to infinity.
