Answer:

10 students/van

48 students/bus

Step-by-step explanation:

(a) 13v+5b = 370

(b) 12v+10b = 600

(a) - (b)

v -5b = -230

v = 5b-230

12(5b-230) + 10b = 600

60b+10b -2760=600

70b=3360

7b=336

b=48

v = 5(48) - 230 = 10

v = 10

Let's check

12(10) +10(48) = 600

Answer/Step-by-step explanation:

Unit cost of apple = $2 let each

Unit cost of orange = $1 per each

a. Cost of 6 apples = 6 × $2 = $12

Cost of 3 oranges = 3 × $1 = $3

b. Cost of 4 apples = 4 × $2 = $8

Cost of 4 oranges = 4 × $1 = $4

c. Cost of 5 apples = 5 × $2 = $10

Cost of 4 oranges = 4 × $1 = $4

d. Cost of 8 apples = 8 × $2 = $16

Cost of 2 oranges = 2 × $1 = $2

Answer:

The answer is

[tex] \huge y = 2x - 5[/tex]

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

From the question we have

[tex]y + 3 = 2(x - 1) \\ y + 3 = 2x - 2 \\ y = 2x - 2 - 3[/tex]

We have the final answer as

[tex]y = 2x - 5[/tex]

Answer:D

Step-by-step explanation:

An equation for each situation, in terms of t, is y = 850e^35t and

y = 700e^70t

The required equation will be in the form y = Ae^kt

where:

If High School A currently has 850 students and is projected to grow by 35 students each year, hence;

Substituting into the formula, we will have:

y = 850e^35t

If High School B currently has 700 students and is projected to grow by 60 students each year, hence;

Substituting into the formula, we will have:

y = 700e^70t

An equation for each situation, in terms of t, is y = 850e^35t and

y = 700e^70t

This is correct.

hope this helps ;D

Answer:

All real square roots of 121 is +11 and -11.

When you square root something, you take the positive and negative of the number, so the square root of 121 would be 11 and -11.

When you do 11 times 11, you get 121 and when you do -11 times -11, you get 121 as well, this is why we do the negative as well.

#teamtrees #WAP (Water And Plant)

Answer:

132 degrees.

Step-by-step explanation:

Let the supplement be x and the angle be y.

x + y = 180 degrees.

y = (3x - 12) degrees.

x + 3x - 12 = 180

4x = 192

x = 48 degrees

y = 132 degrees

Answer:

Step-by-step explanation:

The y-intercept is the point where the line crosses the y axis (horizontal line in graphs). We can clearly see that the y-intercept is -1, since the line intersects the y axis at y = -1.

Ok, now for the slope, we will use this equation, where m is the slope we wish to find.

m = rise/run where rise is the change in y and run is the change in x.

To determine the rise and run, we need two coordinate pairs.

9, -4 and 0, -1 will do

Note: The coordinate pairs are x, y, but slope is y/x, it is important that we do not become confused.

Now, we will subtract one y from the other and then do the same for the x's. It is important that we use the same order for the x's as we do for the y's, in order for the answer to be valid.

Y -4 - -1 = -3

X 9 - 0 = 9

Slope is -3/9 or -1/3

B. Substitution Property

Step-by-step explanation:

Transitive property would be TX=GH and GH=PS then TX+PS

The substitution property of equality is one of many equality properties used to simplify expressions and solve equations.

If PQ + RS = PS and RS = XY, then PQ + XY = PS is an expression using substitution property.

The substitution property states that 'If a variable x is equal to another variable y, then x can be substituted in place of y in any expression and y can be substituted in place of x in any expression.

We have,

If PQ + RS = PS and RS = XY, then PQ + XY = PS.

We are substituting RS with XY on PQ + RS = PS.

We get,

PQ + XY = PS

This expression has been solved using the substitution property.

Thus, If PQ + RS = PS and RS = XY, then PQ + XY = PS is an expression using substitution property.
