If four times the sum of a number and 5 is divided by 3, the result is 16. Step 1. Let x be the number.
Step 2. Four times the number and 5 is divided by 3
Step 3. The result is 16
Step 4. Multiply by 3 to both sides of equation to get rid of denominator
Step 5. Subtract 20 from both sides of equation
Step 6. Divide by 4 to both sides of equation
Step 7 ANSWER is x=7.
I hope the above steps were helpful.
Answer:
True
Step-by-step explanation:
64x³ + 125
64x³ = (4x)³ ← a perfect cube
125 = 5³ ← a perfect cube
Thus 64x³ + 125 ← is a sum of cubes
1. 12a+6=12a+6
2. 12a+6=12a+2
3. 12a+6=4a+6
4. 12a+6=7a+5
Just do the whole process backwards
700*0.01=7
7-2.84=4.16
4.16/0.8=5.2
5.2+1.05=6.25
