Answer:

y = (7 - x) / 2

Step-by-step explanation:

You isolate the y by subtracting the x

2y = 7 - x

and then you divide by two to get the answer to y

(7 - x) / 2

A rental car costs $65.95 if 30 miles are driven and $75.95 if 50 miles are driven. Construct

Mazyrski [523]

Answer:

y = 0.5x + 50.95

Step-by-step explanation:

Given y is total cost while x is total miles

Slope: m = (y2-y1)/(x2-x1)

m = (75.95-65.95)/(50-30) = 10/20 = 0.5

y = mx + b

y = 0.5x + b

75.95 = 0.5(50) + b

b = 50.95

Slope intercept form: y = 0.5x + 50.95

Math question need help please

Answer: $190ft$

Step-by-step explanation:

Side a= 110ft

Side b= ?

Height= 75ft

Area= $11,250ft^2$

$A=\frac{a+b}{2}h$

Solve for b. Let's begin by multiplying by 2 to get rid of the denominator.

$2A=(a+b)h$

Divide by h

$\frac{2A}{h}=a+b$

Subtract a

$\frac{2A}{h}-a=b$

Now plug in your values.

$b=\frac{2A}{h}-a$

$b=\frac{2(11,250ft^2)}{75ft}- 110ft$

$b=\frac{22500ft^2}{75ft}- 110ft$

$b=300ft- 110ft$

$b=190ft$

Tamara finds the sum of two number cubes rolled at the same time. The chart below shows all possible sums from the 36 possible c

Georgia [21]

Answer:

18 times

Step-by-step explanation:

Sample space ; roll of 2 number cubes = 6^2 = 36

Sum of 4 in 2 cube rolls = 3

Probability = required outcome / Total possible outcomes

P(sum of 4) = 3 / 36 = 1 / 12

If number cube is rolled 216 times :

Probability on 1 roll * Number of rolls

(1 / 12) * 216

0.0833333 * 216

= 18
