Evaluate the expression. 33 + 6( 2 + 36 )
Alinara [238K]

Answer: 261

Step-by-step explanation:

You use PEMDAS to solve this problem

you first do the Parenthesis (p)

33+6(2+36)

33+6 (38)

We then multiply first (M)

33 + 6(38) - we know that 8 times 6 is 48 ; 6 times 3 is 18 +4 because we brought down the 4 from 48 to 3. which will be equal to 228

33 + 228

Heeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeelp and do the order of operation
umka21 [38]

Answer:

<h3>The answer is 7/12.</h3>

Step-by-step explanation:

( \frac{2}{3}  -  \frac{1}{4} ) + ( \frac{1}{2}  \times  \frac{1}{3} )

Solve the terms in the bracket first

That's find the LCM of the ones which are subtracting

LCM of 3 and 4 is 12

That's

\frac{2}{3}  -  \frac{1}{4}  =  \frac{8 - 3}{12}  =  \frac{5}{12}

Next multiply the other terms in the other bracket

That's

\frac{1}{2}  \times  \frac{1}{3}   =  \frac{1}{6}

Add both results

That's

\frac{5}{12}  +  \frac{1}{6}

Find the LCM

The LCM is 12

We get the final answer as

\frac{5}{12}  +  \frac{1}{6}  =  \frac{5 + 2}{12}  =  \frac{7}{12}

Hope this helps you

Find a linear equation that is perpendicular to y= 2x + 4 and passes through (-5, -3)
Trava [24]

Answer:

y=-1/2x+7/2

Step-by-step explanation:

two lines are perpendicular if the product of the slopes is equal to -1

the slope for y=2x+4 is 2

2*x=-1

x=-1/2

the formula for the slope is

(y2-y1)/(x2-x1)=m

we know y1 and x1

(y+5)/(x+3)=-1/2

y+5=x+3/2

2y+10=x+3

2y=x-7

y=-1/2x+7/2

Find the area (in square feet) of a rectangle that measures 17" × 3'10".
Kitty [74]

Answer:

65 feet and 2 inches

Step-by-step explanation:

to find the area of a rectangle you need to multiply length times width in this case 17" times 3'10". But first you must convert everything into the same form(in this case feet) so first you can convert everything to inches by multiplying 3 times 12  which gives you 36 then add the 10, so it is now 46 inches then multiply that by 17 and altogether it is 782 inches, then divide by 12 (to convert it back to feet) and the answer is 65.1666666667. After you can round and get 65 feet and 2 inches.

Joe needs to buy supplies for a birthday party. At the store, balloons cost $0.50 each and party hats each cost $1.25. If Joe wa
VladimirAG [237]

Answer:

0.50b+1.25h=20

Step-by-step explanation:

Let b be the number of balloons and h be number of party hats.

We have been given that balloons cost $0.50 each, so cost of b balloons will be 0.50b.

We are also told that party hats each cost $1.25, so cost of h party hats will be 1.25h.

Further, Joe wants to spend exactly $20 on the party supplies. We can represent this information in an equation as:

0.50b+1.25h=20

Therefore, the equation 0.50b+1.25h=20 represents the number of balloons ( b) and the number of party hats ( h) that Joe can buy spending exactly $20.
