Answer: I believe... -17.

Follow the order of operation. PEMDAS....

1+1 x 2 - (2+3) / 2 x 8.

First add up the 2 and the 3 because they're in parenthesis.

1+1 x 2 - (5) / 2 x 8

The multiply the numbers...

1+2 - 5/2 x 8

Multiply the 5/2 and 8 together.

1+2 -20

Add up the 1 and the 2

3-20

Subtract,

-17

So the answer is -17

Answer is -17

Step by step

I follow PEMDAS rules of math

1 + 1 x 2 - (2+3) / 2 x 8

Distribute to eliminate parentheses first

1 + 1x2 -2-3 /2 x8

Answers

Let's express these all in decimal form.

-π = -3.14
-3.2 = -3.2
-3 1/4 = -3.25
-√9 (not to be confused with √-9) = -3

So, rank these.

-3 > -3.14 > -3.2 > -3.25
If we revert these to their unsimplified forms:
-√9 > -π > -3.2 > -3 1/4

What is the equation of the line in slope-intercept form?

Answers

y = 5/2x + 5

5/2 is the slope (rise over run) and we know it is positive because it is going up from left to right. You could also say 2.5, but I don’t know if your teacher wants you to leave it in fraction form. + 5 is the y-intercept.

Y=5/2x+5 is ur answer hope this helps

Answer: 9

Explanation:

The angles marked are corresponding angles, since they correspond in the same direction. Both are pointing to the southwest direction.

Since line DE is parallel to line FG, this means the corresponding angles mentioned are congruent.

Set them equal to each other and solve for x.

7x+18 = 81

7x = 81-18

Hall swam 34 laps in 1 2/3 hours. Find his swimming rate in laps per hour

Answers

1 2/3 = 5/3

5/3 ÷ 5/3 = 1

34 ÷ 5/3 = 34 x 3/5

102/5 = 20.4

20.4 laps per hour

First convert your fraction into a decimal
1 2/3 =1.66
They swam 34 laps so take 34 and divide it by 1.66
34/1.66= 20.48
So his swimming rate is 20.48 laps per hour

2 4/5 ounces of candy when they came over to play video games. How many ounces of candy does Joseph have left?

Please try to give me a step by step explanation! ^_^

Answers

Answer:

4 9/20

Step-by-step explanation:

We are subtracting since he gave them candy

Let's get the whole numbers out of the way

7 - 2 = 5

Now we subtract the fractions

1 / 4 - 4 / 5. We need to find the LCD (Lowest common denominator) of the fractions which is 20 because 4 x 5 = 20 and 5 x 4 = 20

Rewriting the denominators and numerators:

Since we multiply 4 by 5 to get 20 we'll have to do the same to the numerator (1)

1 x 5 = 5

Now we do the same to 4/5. 5 x 4 = 20 and 4 x 4 = 16.

New fractions

5/20 - 16/20 switch it 16 / 20 - 5 / 20 = 11/20 and we get the answer from subtracting the whole numbers by 11/20 (the answer we got from subtracting fractions) 5 - 11/20 = 4 9/20

Answers

Answer:

9641 + 9641 = 19282

Step-by-step explanation:

You want to assign a different digit to each of the letters H, A, L, T, E, R such that ...

HALT + HALT = THERE

Solution

The T in the most significant digit of the sum must be T = 1, because a carry from the sum of two digits cannot exceed 1. That means E = 2. In order for H+H = TH, we must have ...

H + H + 1 = 10 + H

H = 9

In order for there to be a carry into the 4th column (from the right), the value of A must be 5 more than the value of T:

A = 6

Since E in the third sum digit is even, there can be no carry from the sum L +L = R. This leaves R an even digit not 0, 2, or 6. It cannot be 4, because that would require L=2, but we already have E=2. This leaves R = 8 and L = 4.

The sum is ...

HALT +HALT = THERE ⇒ 9641 +9641 = 19282

The value of THERE is 19282.
