I feel it should be 30 because x represents the number of lessons, and 30 is multiplied by that.
A = Anthony's weight
B = Anthony's brother's weight
A = 2B + 9 Plug in Anthony's weight
59 = 2B + 9 Subtract 9 from both sides
50 = 2B DIvide both sides by B
25 = B Switch the sides to make it easier to read
B = 25
Anthony's brother weighs 25 pounds.
Complete question :
Hayley is buying herbs. She wants to buy 5/6 ounce of basil. The scale she is using to weigh the basil displays the weight as a decimal. How will she know when the display on the scale is correct to the tenths place? Explain your reasoning.
Answer:
0.8
Step-by-step explanation:
To obtain the fractional expression of weight in decimal form:
5/ 6 ounce of bassil is converted into decimal :
5 / 6 = 0.8333
Hence, for a fraction of 5 /6, we obtain;
5/6 = 0.8333

I think it's -35. The steps to get that number is subtracting the 3 to the right side. Then you have -2 - 3 which equals to -5. Then you still have x/7= -5. Get rid of 7 from the x and do the same thing to the other side but you multiply 7 and -5. Last you your would be x= -35.
When it says to estimate, I always think of doing it by hand to show work. So set it up like this:
96
<u>x 34</u>
So follow it out multiplying across 4*6 and 4*9 carrying over as needed to get it to look like this:
96
<u>x 34</u>
384
Do the same for the 3 to get this:
96
<u>x 34</u>
384
2880
Add 384+2880=3264
Your final answer is 3,264
