Answer- b+t=90 (or bb + tt = 90 ignore if this was a mistake)
If we know that 90 is an absolute total, that will go behind the equal sign
?=90;
We know that we can make any mixture of burritos or tacos, but they have to equal up to ninety. As you stated bb= burritos and tt= tacos. (If that is a mistake, instead of putting bb or tt, just put the single letter b or t)
This means our equation would have to have a certain number times burritos and a certain number times tacos that equal 90.
Our equation should look a little like this
(number of burritos ) + (number of tacos) = 90
b + t =90 or with your values bb+tt=90
HOPE THIS HELPS & GOOD LUCK
Step-by-step explanation:
the scanned description is very hard to understand.
so I think what happened :
16x² - 9 = 16
then the first error :
sqrt(16x²) - sqrt(9) = sqrt(16)
that is wrong, as you cannot split a + or - operation inside a sqrt function into + or - separate sqrt results of the parts.
so, correctly, the only possible transformation involving sqrt for both sides :
sqrt(16x² - 9) = sqrt(16)
but it would be even easier to clean up the various constant numbers with each other.
so,
16x² - 9 = 16
16x² = 25
and now we trashes the square root
sqrt(16x²) = sqrt(25)
4x = 5
x = 5/4 or x = -5/4
and I cannot see or understand for my life what the second equation was, as Daniel did something wrong, so I cannot deduct the original equation out of a supposedly wrong
y³ - 1 = 7
Y = 7x + 12
-7y = x + 56
-7y = x + 56
-7 -7
y = ⁻¹/₇ - 8

Answer: There are 990 croissants
Step-by-step explanation:
If 45% of them are pretzels then 55% of the pastries hs to be croissants.
Multiply 55% by the total number of pastries to find the number of croissants.
55% * 1,800 = 990
