Answer:

X = 10

Step-by-step explanation:

Step 1: Cross-multiply.

15x − 10/6 = 6x + 10/3

(15x − 10) * (3) = (6x + 10) * (6)

45x − 30 = 36x + 60

Step 2: Subtract 36x from both sides.

45x − 30 − 36x = 36x + 60 − 36x

9x − 30 = 60

Step 3: Add 30 to both sides.

9x − 30 + 30 = 60 + 30

9x = 90

Step 4: Divide both sides by 9.

9x/9 = 90/9

X = 10

Hope this helps :-)

FIRST ANSWER GETS BRANLIEST

Darina [25.2K]

There are two steps to this problem. The first step is to make an equation for the cost of each company. The cost of each one involves 2 variables. However, we can ignore the number of days since the question asks for per day.

CostA = 90 + .40(miles)

CostB = 30 + .70(miles)

We want to know when A is a better deal or when A costs less. That is when CostA < CostB. We can then substitute the right sides of our equations into the inequality. This will give:

90 + .40(miles) < 30 + .70(miles) This is where we will now begin to solve for the number of miles.

-30 -30 Subtract 30 from both sides.

60 + .4(miles) < .7(miles) Simplify

-.4(miles) -.4(miles) Subtract .4(miles) from both sides

60 < .3(miles) Simplify

/.3 /.3 Divide both sides by .3

200 < miles Simplify

So for A to cost less the number of miles must be greater than 200.

Solve for x^2-2x+1=0

seraphim [82]

Answer:

$x=1$

Step-by-step explanation:

$x^2-2x+1=0\\$

We will start by using the quadratic formula.

$\frac{-(-2)+-\sqrt{(-2)^2-4(1)(1)}}{2(1)}$

We will simplify that and get:

$\frac{-(-2)}{2(1)}$

So our answers would be:

$x=1$

Find perimeter in cm of the diagram

boyakko [2]

3 sides of square is 3*12=36 cm

perimeter for the full circle is 2 * pi * radius

which is =2 * 22/7 * 12 =75.43 cm

so 360° =75.43 cm

for 150° = 75.43/360 *150 =31.43

all together =36 +31.43 =67.43 cm
