Answer:
The statement is false.
Step-by-step explanation:
To begin an indirect proof, you assume the converse of what you intend to prove is true. This is false.
Rather the correct answer is that to begin an indirect proof, you assume the inverse of what you intend to prove is true.
The converse can be either true or false, depending on what the original statement is, so assuming the converse is pointless.
Answer:
-4 or 5
Step-by-step explanation:
let number be x
x²-x=20
Rearrange
x²-x-20=0
(x+4)(x-5)=0
Separate
x+4=0, x-5=0
x=-4 or 5
For the answer to be 130, change this....:
310 – 20 ÷ 2 × 5 + 13
....into this:
310 – 20 ÷ 2 × (5 + 13)
310 – 20 ÷ 2 × (5 + 13)
310 – 20 ÷ 2 × 18
310 - 10 x 18
310 - 180
= 130
Three hundred ten million, seven hundred sixty-three thousand, one hundred thirty-six
