Change the percents to decimals (by moving the decimal 2places to the left)
(.24, .38)
Multiply each by 112,483.
(.24x112483, .38x112483)
(26,996, 42,744). You can’t have decimals because people are whole numbers. So round to the nearest whole number
Richardson’s ice cream would be .49 $ for one ounce. you would divide both 7.99 and 16 by 16. Friendlys ice cream would be .54$ and ounce. to do that you would divide both 6 and 3.29 by 6. Richardson’s ice cream is a better buy.
Answer:
70/9
Step-by-step explanation:
Let's solve your equation step-by-step.
4−138=6(1−3x)
Step 1: Simplify both sides of the equation.
4−138=6(1−3x)
4+−138=(6)(1)+(6)(−3x)(Distribute)
4+−138=6+−18x
(4+−138)=−18x+6(Combine Like Terms)
−134=−18x+6
−134=−18x+6
Step 2: Flip the equation.
−18x+6=−134
Step 3: Subtract 6 from both sides.
−18x+6−6=−134−6
−18x=−140
Step 4: Divide both sides by -18.
−18x/-18=−140/-18
x=70/9
1x + 3y = 5
<u>2x - 3y = 1</u>
<u>3x</u> = <u>6</u>
3 3
x = 2
2(2) - 3y = 1
4 - 3y = 1
<u> -4 -4</u>
-<u>3y</u> = <u>-3</u>
-3 -3
y = 1
(x, y) = (2, 1)
Answer:
2006 years old.
Step-by-step explanation:
If it had 50% of its carbon-14 it would be 5730 years old.
Since it has 65% left it is younger than 5730 years.
So it is (1 - 0.65) * 5730
= 2005.5 years old.
