2x+4=7 subtract 4 from both sides
2x=3 divide both sides by 2
x=3/2
x=1.5

Answer:
12
Step-by-step explanation:
The length of the hypotenuse, PQ, can be found from the Pythagorean theorem:
PQ² = QR² +PR²
PQ² = 3² + 4² = 25
PQ = √25 = 5
The perimeter is the sum of side lengths:
P = 3 + 4 + 5 = 12
The perimeter of this triangle is 12 units.
470 miles in 2 hrs......470/2 = 235 per hr
in 12 hrs...
235 * 12 = 2820 miles <==
Answer:
3/
8 is greater than 3/
12 because if you cross multiply 12 times 3 is 36 and 3 times 8 is 24

Answer: 7.58 years
Step-by-step explanation:
When it comes to finding out how long it will take for an investment to double, one can use the Rule of 72.
The Rule of 72 estimates the amount of time it will take to double an investment when you divide 72 by the interest rate:
= 72 / r
= 72 / 9.5
= 7.58 years
