Answer:
x = 23
Step-by-step explanation:
Hello There!
We are given that AC and BD are diagonals of a rectangle
If you didn't know diagonals are congruent
So given that BC = 56 and AC = 2x + 10 we can use this equation to solve for x
56 = 2x + 10
now we solve for x
step 1 subtract 10 from each side
56 - 10 = 46
10 - 10 cancels out
now we have 46 = 2x
step 2 divide each side by 2
46/2=23
2x/2=x
we're left with x = 23
Answer: 1) 28 cups; 2)1.6 
Step-by-step explanation:
1) - As you know, there are 7 days in a week.
- Then, if Fred eats 4 cups of brain flavored tofu each day, you can calculate the amount he eats every week (which you can call
) by multiplying 4 cups by 7:

- Convert the result from cups to gallons:

2) - There are 60 minutes in an hour.
- Karen eats 3 pints of ice cream in an hour, therefore, she eats 3 pints in 60 minutes.
- You need to divide 3 pints by 60 minutes to calculate the amount she eats in an hour (which you can call
) by dividing 3 pints by 60 minutes:

- Convert the result to tablespoons:

- The answer is: 
Answer:
$1.20
Step-by-step explanation:
9.20 x 4 = 36.8

38 - 36.8 = 1.20
We know that
<span>A number x, rounded to 1 decimal place is 12.3
</span><span>so
x>=12.25
and
x < 12.35
</span><span>the error interval for x is the interval [12.25,12.35)
</span>
the answer is
[12.25,12.35)
