Answer: False
Step-by-step explanation: First, you are going to multiply the numbers in the first set of parenthesis, getting 72. Now, have 72 take the place of 12x6 in the equation. Your new equation looks like this: 0.3 x <u><em>72</em></u> = 0.4(12-3).
Going off of step one, you will be doing the same thing with the second set, but you will be subtracting instead. You will get 9, and plug it place of the parenthesis. Your equation now looks like o.3 x 72 = 0.4 x <em><u>9.</u></em>
<em><u /></em>
Next, you will multiply the set of numbers on the left side of the equal sign, getting 21.6. You now have an equation of <em><u>21.6</u></em> = 0.4 x 9.
Going off of step 3, you are going to do the exact same thing we did in step 3. Multiply 0.4 and 9, and you will get 3.6. The equation now looks like 21.6 = <u><em>3.6</em></u>.
Now, the inequality is false because the left-hand side and right-hand side are two completely different numbers. A bigger number cannot be equal to a smaller number.
Hope this helps!
Answer:
Hmm, I think the answer is 57.5.
Step-by-step explanation:
Since 46 = 3/4, we divide 46 by 4 to get one fourth. That is 11.5 . Then, multiply it by 4 to get by one minute. 11.5 x 4 = 57.5
Yes the have the same 78° angle . The smaller one should be able to fit inside the larger one.

Explanation: Distributive Property
Answer: Total weight will be 7.055 ounces.
Step-by-step explanation:
Since we have given that
Ideal weight of a nickel = 0.176 ounce
Number of nickels in a roll = 40
Total weight becomes

Error that was allowed in total weight = 0.015 ounce
So, Total weight will be

Hence, Total weight will be 7.055 ounces.
