Answer:

5 is NOT a solution to the equation.

t = 6

Step-by-step explanation:

Step 1: Write out equation

2t - 1 = 11

Step 2: Add 1 to both sides

2t = 12

Step 3: Divide both sides by 2

t = 6

last year the cost of a season ticket for a rugby club £370. This year the cost of a season ticket for the club has been increas

Elden [556K]

Answer:

$\frac{80}{370}$ OR $\frac{8}{37}$

Step-by-step explanation:

So first you find the difference between the new cost and the old cost:

450 - 370 = 80

So the increase was 80.

When you write it as a fraction you write the increase ( 80 ) over the starting cost ( 370 ).

Thus the answer becomes $\frac{80}{370}$

But you can always reduce it to its lowest terms thus:

$\frac{8}{37}$

What is the equation of the line that passes through (-2, 2) and (1, -4)?

poizon [28]

Answer:

y = - 2x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ = (- 2, 2) and (x₂, y₂ ) = (1, - 4)

m = $\frac{-4-2}{1+2}$ = $\frac{-6}{3}$ = - 2, thus

y = - 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 2, 2), then

2 = 4 + c ⇒ c = 2 - 4 = - 2

y = - 2x - 2 ← equation of line

STALIN [3.7K]

Hey!

To find the percentage increase, you must use this formula:

{(50 - 92 / 50] × 100 = 84%

So, the percent increase from 50 to 92 is: 84%.

Jonas weight 63 pounds. jane weight 67 pounds. round each number to the nearest ten.

IrinaVladis [17]

Answer:

Jonas = 60 pounds

Jane = 70 pounds

Remember- 5 or more, raise the score. 4 or less, let it rest.

Jonas is 63 pounds. 3 is less than 4, so rounded to the nearest ten would be 60 pounds.

Meanwhile, Jane is 67 pounds. 7 is more than 5, so we will raise the score.

So, 67 rounded to the nearest ten would be 70.

You have your answers. 60 and 70. Hope this helps!
