Expressions in brackets should always be calculated first. If there are no brackets in an algebraic expression, it means that multiplication and division must be done first, and addition and subtraction afterwards.

Answer: 122 1/2 minutes

Step-by-step explanation:

I got this answer by first subtracting 5.25-3.50=1.75 and that was how many minutes it took per mile then I multiplied 1.75x70=122.50 to get my answer.

Answer: Ben can only rent the boat for 5 hours.

Step-by-step explanation:

You have to set up an equation. It would be 20 + 12h = 80

20+12x=80

12x=80-20

Then divide both sides 12x=60

And you get 5

Answer:

yes

Step-by-step explanation:

It is true

Answer:

Yes

Step-by-step explanation:

1,4 the first coordinate is X and the second is Y so it means y = 4 and X = 1

So that means the equation becomes 4 = 4 times 1 which is correct since 4 times 1 is 4 and 4=4

Answer:

FOR THE FIRST ONE : 36.4

FOR THE SECOND : 18.9

FOR THE THIRD : X*(0.30)

Step-by-step explanation:

IN THE FIRST EXAMPLE I MULTIPLIED THE NUMBER BY 0.30 AND THEN ADDED THE NUMBER TO THE MAIN NUMBER

IN THE SECOND I MADE THE SAME BUT I SUBTRACTED INSTAID

IN THE THIRD I WILL MULTIPLY X BY 0.30 AND THEN SUBTRACT THE NUMBER FROM THE VALUE OF X

Answer:

Step-by-step explanation:

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

Step-by-step explanation:

Zero represents sea level.

15 is above sea level because it’s a above 0.

-25 is below sea level because it’s below 0.

Second pic

Zero represents negative and positive degrees ( not sure how to word it )

-5 degrees is below average because it’s below 0.

55 degrees is above average because it’s above 0.

Third pic

Zero represents average temperature

-30 degrees is below average because it’s below 0

70 degrees is above average because it’s above 0

Fourth pic

Zero represents sea level

-10 feet is below sea level because it’s below 0

20 feet is above sea level because it’s above 0

The answer is 9 in.3

Answer:

x = -4

Step-by-step explanation:

let x equal the number

so

1/4(-x)+2=1/2(-x)+4

-1/4x + 2 = -1/2x + 4

+1/2x          +1/2x

1/2x + 2 = 4

        -2    -2

1/2x = 2

x = -4

Answer: x=-8

Step-by-step explanation:

1/4x+2=2x+16

Multiply by four to get rid of the fractions

X+8=2x+16

Combine like terms

-x=8

x=-8

Answer:

2?

Step-by-step explanation:

i think its 2 because 1 is an odd number and it goes 1,1 ( two odd numbers) then __ 3,5 ( two more odd numbers then 8,13,21( even number then two more odd numbers) the 34( even number). i'm thinking the pattern is odd, odd, even, odd, odd, even, odd odd, even.

Answer:

A, C

B, A

C, C

Step-by-step explanation:

A, take 33-9 then you get 24, divide 24 by 8 and get 3

B,  re-wright X/3 to X over 3, then subtract 5 from 8, you're left with 3, now find what X has to equal to make 3, X=9

C, same concept as the last one

Answer:

length 4.96 cm(4 24/25) Width 1.80 cm( 1 8/10 cm)

Step-by-step explanation:

If the perimeter is 15 1/3 cm and the length is 3 1/6 cm longer than the width. Then first you have to take away 6 1/8. How did I get that? Because since a rectangle has 2 sides of length and 2 sides of width, I added 3 1/6+3 1/6. When we subtract the whole number you get 7. And when you subtract the fractions you get 5/24. I got that by doing 1/3x8  and 1/8x3. So i get a deminitor of 24. Then you have to divide 7 5/24 into 4 parts, since there is four sides. Which then you get ~1.80. That means the width is abut 1.80. And if you add the 3 1/6 back on the length it will be about 4.96.

Answer:

Scale Drawing - Two dimensional model of an object.

Scale Model - Three dimensional model of an object.

Step-by-step explanation:

Answer:

C.)

Step-by-step explanation:

Add the area if the rectangle, to the area of the two semi-circles.

Area of Rectangle: L: 6[tex]\frac{5}{8}[/tex] in times W: 8 in = 53 in

Area of Semi-circle: [tex]\frac{1}{2}[/tex](πr2): [tex]\frac{1}{2}[/tex](π(4)2) = 25.13  

(r is always half of diameter (d) so r=4)

53 + 25.13 + 25.13 = 103.26
