PLZ HELP!!!!!! What is 1-34 divided by (3x8-7) - 2x3

1 answer:

8 0

You do the brackets first so 3x8 = 24 - 7 = 17

You then do divide so 34/17 = 2

You then do the multiplication so 2x3= 6

Then you have 1-2-6 = - 7

The order you do it in is BIDMAS
B = brackets
I = indices
D = division
M = multiplication
A = addition
S = subtraction

So the answer is - 7

An ice cream machine produced 52 ice creams per minute. After reconditioning, its speed increased to 65 ice creams per minute. B

Anastasy [175]

Answer:25 %

Step-by-step explanation:

Given

Earlier machine was producing 52 ice cream per minute and

Now it is Producing 65 ice creams per minute

So percentage increase of the machine $=\frac{\text{final-Initial}}{\text{Initial}}\times 100$

$=\frac{65-52}{52}\times 100$

$=\frac{13}{52}\times 100$

$=\frac{1}{4}\times 100=25\ \%$

So there is increase of 25 % in speed

Solve: log4(7t + 2) = 2

IRISSAK [1]

Answer:

The required value of t is equal to 2

Step-by-step explanation:

We need to solve the following expression :

$\log_4(7t+2)=2$

Now, using the base rule :

$2=\log_4(4^2)\\\\\implies 2= \log_4(16)$

Now, using this value of 2

$\log_4(7t+2)=2\\\\\implies\log_4(7t+2)=\log_4(16)\\\\\implies 7t+2=16\\\\\implies 7t=16-2\\\\\implies 7t=14\\\\\implies t = 2$

Hence, The required value of t is equal to 2

Elena-2011 [213]

You need a common denominator while subtracting because really a fraction is a division problem and you cannot do 4/5-8/9 it does not make sense as for multiplication you really just multiplying everything that is why it makes sense.
