Answer:

= −23

Step-by-step explanation:

Subtract the numbers

3 + 7 - 11-31 = 160

3-24 - 11 = 160

Combine like terms

3 - 24-11 = 160

-8 - 24 = 160

Add 24 to both sides of the equation

-8 - 24 = 160

-8 - 24 + 24 = 160 + 24

Simplify

Add the numbers

Add the numbers

--> -8 = 184

Divide both sides of the equation by the same term

-8 = 184

-8/-8 = 184/-8

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

--> = -23

. Write an equation of the line that passes through
irina [24]

Answer:

y = 1/3 x + 4

Step-by-step explanation:

The slopes of perpendicular lines are negative reciprocals. The given line is

y = -3x + 7

which is already in the slope-intercept form, y = mx + b, where m is the slope.

The slope of the given line is -3.

The slope of the perpendicular is the negative reciprocal of -3 which is 1/3.

The line we are looking for has an equation of the form

y = 1/3x + b

We need to find b. We use the x- and y-coordinates of the given point as x and y in the equation above, and we solve for b.

y = 1/3x + b

5 = (1/3)(3) + b

5 = 1 + b

4 = b

Now that we know that b = 4, we replace b with 4 in the equation

y = 1/3x + b to get the answer.

Answer: y = 1/3 x + 4

mafiozo [28]

Answer:

£70

Step-by-step explanation:

There are ten people and each person pays £56 so the total cost will be 10x£56 = £560

The boat will be hired out for the same price (£560) and there are eight people this time, so £560 divided by 8 = £70. This means each person will pay £70.
