Answer:
11/4
Step-by-step explanation:
The question in math symbols 3/4 - 1/2(4*-1)
By Pemdas (order of operations) we start with the parenthesis
3/4 - 1/2(4*-1) = 3/4 - 1/2(-4)
Because there are parenthesis next to a number, this is a multiplication
3/4 - 1/2(-4) = 3/4 - (-2)
The double negative can be converted into a positive
3/4 - (-2) = 3/4 + 2
Then we can convert the 2 into a fraction of fourths
3/4 + 2 = 3/4 + 8/4
Now we just add the numerators and keep the denominator
3/4 + 8/4 = 11/4
99_97=2+95=97-93=4+7=11-5=6+3=9-1=8
Answer:
x= 8
Step-by-step explanation:
60/48=1.25
15/1.25= 12
12-4=8
Answer:
34, 50
Step-by-step explanation:
An amount divide by 17: 34÷17=2
25 less than x: 50-25=25
Answer:
x = 5.5
Step-by-step explanation:
Using a trig ratio, you can use sin, which is opposite over hypotenuse. 
Now, multiply both sides by 11
this simplifies to x = 
or 5.5.
Since sin30 is 
radians, it can be written as 
.
