X= hours needed by the designer 
x+ 16= hours needed by the assistant 

In 6 hours the designer does 6/x of the job 
In 6 hours the assistant does 6/(x + 16) of the job
Together they complete the 1 job


6/x+ 6/( x+16)= 1
6(x+16) +6x =+ x2<span> </span><span>16x
6x+ 96+ 6x= </span>x<span>2+ 16x 
0= </span>x2+ 4x- 96 
0= (x+12)(x-8)
{-12/8}

The designer needs 8 hours and the assistant needs 24 hours.

Drag each equation to show if it could be a correct first step to solving the equation 9(x + 2) = 90
irakobra [83]
No signs of draggin stuff

so PEMDAS

so wha yyou woul ddo first is see if parenthasees can be simplified
it cannot
so next we do multiply or distribute the 9
9(x+2)=9x+18

so now we have
9x+18=90
then we do subtraction
of 18
9x=72
divide 9
x=8


so order is multiplication then subtraction then division

Cos3x+cosx=2cos2xcosx
andrew-mc [135]

cos(3x)+cos(x)=2\cdot cos\left(\dfrac{3x+x}{2}\right)\cdot cos\left(\dfrac{3x-x}{2}\right)=2\cdot cos(2x)\cdot cos(x).

How to calculate the perpendicular distance from a line produced?? Thanks!!!
kykrilka [37]

Answer:d=a2+b2 ∣a(x0)+b(y0)+c∣. So given a line of the form a x + b y + c ax+by+c ax+by+c and a point ( x 0 , y 0 ) , (x_{0},y_{0}), (x0,y0), the perpendicular distance can be found by the above formula.

Step-by-step explanation:

if that is any help

I’m studying for my Sat later in the month, and even using the answer key I don’t understand how to solve this question. Help?
shepuryov [24]

So with this equation, since the volume of the cylinder is 96 pi, plug that into the V variable, and since the radius of one of the marbles is 3, plug that into the r variable. From here, we can solve for x: 96\pi =24\pi +x(\frac{4}{3}\pi*3^3)

Firstly, solve the parentheses: 96\pi =24\pi +x(\frac{4}{3}\pi*27)\\ 96\pi =24\pi +x(36\pi)

Next, multiply 36 pi and x: 96\pi = 24\pi +36\pi x

Next, subtract 24 pi on both sides: 72\pi =36\pi x

Lastly, divide both sides by 36 pi, and your answer will be 2=x, or B.

If a number is divisible by both 2 and 3 then we can say the number is divisible by
andre [41]
6 because if one number is divisible by another number's factors, then the first number is divisible by the second number. for example, take the numbers 18 and 6.  the factors of 6 are 2 and 3. 18 is divisible by both 2 and 3, therefore it has to be divisible by 6.
