The correct answer is A. (1, 2)
Answer:
10a and 5a+2a+3a
Step-by-step explanation:
6a + 4a = 10a
10a = 10a
9a is not equal to 10a
10+a is not equal to 10a
5a+2a+3a = 10a
6a - 4a is not equal to 10a
a^10 is not equal to 10a
Hope this helps! :)
I think when you have a fraction like that, you multiply the denominator on both sides obviously by the first step
1 - 3x/5 = -7
Multiply on both sides
1 - 3x/5 * 5 = -7 * 5
and Solve
1 - 3x = -35
Subtract 1 from both sides of the equation
-3x = -36
Divide both sides by -3
-3x / -3 = -36 / -3 (← answer)
x = 12

7x - 3(-2) = 23
7x - - 6 = 23 (two minuses make a plus)
so it’s gonna be 7x + 6 = 23
Now you have isolate you x, so move everything else to the other side, but remember to change your sign when transferring to the other side
7x = 23 - 6
7x = 17
To isolate x in this multiple, you divide by 7 (because the inverse of multiplication is division)
x = 17/7
First let's find how many total ounces it would be by multiplying 16 ounces by the number of mugs (26).
16 × 26 = 416
So she needs 416 ounces of coffee. Now we have to convert ounces to quarts. We need to know that there are 32 ounces per quart. So to find quarts we divide 416 ounces by 32...
416 ÷ 32 = 13 quarts
*FYI- since the mugs hold 16 ounces we can see that 16 is half of 32 so we could have just taken 1/2 of 26 mugs which is 13.
