joja [24]

Answer:

Rate = 0.035 per weeks

Step-by-step explanation:

Given that,

An artist has completed 1/14 of a painting in 2 weeks.

We need to find the rate at which she is working. Let the rate is R. It can be calculated by dividing part that is completed and time.

R=\dfrac{\dfrac{1}{14}}{2}\\\\R=0.035\ \text{per weeks}

Hence, her rate is 0.035 per weeks.

HELPPHELPPPPP HELLPP PLEASEEE
Lilit [14]

Answer:

The answers of all four questions are below.

Step-by-step explanation:

(5)4+2x=−2x+44

Step 1: Simplify both sides of the equation.

2x+4=−2x+44

Step 2: Add 2x to both sides.

2x+4+2x=−2x+44+2x

4x+4=44

Step 3: Subtract 4 from both sides.

4x+4−4=44−4

4x=40

Step 4: Divide both sides by 4.

4x/4=40/4

x=10

-----------------------------------------------------------------------------------------------------------------

(6)114−3x=194−11x

Step 1: Simplify both sides of the equation.

114−3x=194−11x

114+−3x=194+−11x

−3x+114=−11x+194

Step 2: Add 11x to both sides.

−3x+114+11x=−11x+194+11x

8x+114=194

Step 3: Subtract 114 from both sides.

8x+114−114=194−114

8x=80

Step 4: Divide both sides by 8.

8x/8 = 80/8

x=10

------------------------------------------------------------------------------------------------------

(7)4x-12=-2x+36

4x-12+12=-2x+36+12

4x=-2x+48

4x+2x=-2x+48+2x

6x=48

6x/6=48/6

x=8

-----------------------------------------------------------------------------------------------------------

(9)-3x+90=117-12x

-3x+90-90=117-12x-90

-3x=-12x+27

-3x+12x=-12x+27+12x

9x=27

9x/9=27/9

x=3

-------------------------------------------------------------------------------------------------------
