Okay the equation is 1/6x + 1/30

It is asking us to plug in 1/5 so let’s plug it in

1/6(1/5) + 1/30 = 1/30 + 1/30 = 2/30

So we reduce the fraction and the answer is 1/15

Step-by-step explanation:

1/6 x 1/5 + 1/30

= 1/30 + 1/30

= 2/30

1..) 2x +15 = 35

Masja [62]

Answer:

1) $x=10$

2) $x=3$

Step-by-step explanation:

$2x+15=35$

Subtract 15 from both sides

$2x=20$

Divide both sides by 2

$x=10$

$2(10)+15=35$

$20+15=35$

$35=35$

this shows that 10 is the right answer

$7x-3=18$

Add 3 to both sides

$7x=21$

Divide both sides by 7

$x=3$

$7(3)-3=18$

$21-3=18$

$18=18$

this shows that 3 is the right answer

Hope this helps

Maggie only wore sandals tracker on two of the days that she trained so from her fitness trackers she verified that on the third

KIM [24]

We know form our problem that the third day she biked 20 miles, so we have the point (3,20). We also know that on the eighth day she biked 35 miles, so our second point is (8,35).

To relate our two point we are going to use the slope formula: $m= \frac{x_{2}-x_{1}}{y_{2}-y_{1}}$
We can infer form our points that $x_{1}=3$ , $y_{1}=20$ , $x_{2}=8$ , and $y_{2}=35$ . so lets replace those values in our slope formula:
$m= \frac{35-20}{8-3}$
$m= \frac{15}{5}$
$m=3$

Now that we have the slope, we can use the point-slope formula determine the equation of the line that best fit the set for Maggie’s data.
Point-slope formula: $y-y_{1}=m(x-x_{1})$
$y-20=3(x-3)$
$y-20=3x-9$
$y=3x+11$

We can conclude that the equation of the line that best fit the set for Maggie’s data is $y=3x+11$ .

Ishaan is 333 times as old as christopher and is also 141414 years older than christopher.

GalinKa [24]

Ishaan is 21, Christopher is 7 No actual question given, but I will assume that the question is "How old are they?". If that's the case, we can create two equations. I'll use I for Ishaan's age and C for Christopher's. I will also assume that there's been some formatting issues here and for some reason, numbers are repeated 3 times without any spaces. So "Ishaan is 3 times as old as Christopher" I = 3C "is also 14 years older than Christopher I = C + 14 Since both equations are equal to each other, let's set them equal. So 3C = C + 14 2C = 14 C = 7 So Christopher is 7. And we can use the equation I = C + 14 to get Ishaan's age. So I = C + 14 I = 7 + 14 I = 21
