evaluate 11.5x + 10.7y when x = 3 and y = 4

Answers

Answer: 77.3

Step-by-step explanation:

11.5(3)+10.7(4)

11.5 times 3 equals 34.5

and 10.7 times 4 equals 42.8

34.5 plus 42.8 equals 77.3

Answer:

77.3 (see below)

Step-by-step explanation:

To solve, plug in the values given into the expression given and simplify:

11.5x + 10.7y

11.5 (3) + 10.7 (4)

34.5 + 42.8

PLEASE HELP ME ON THIS THE ANSWERS ARE 1/3 cm/s, 1/2 cm/s, 2/3 cm/s, and 3/2 cm/s

Answers

Answer: 3/2 cm per second

========================================================

Explanation:

We could compute the slope of this line to get the answer, or we could simply compute y/x. This shortcut only works because the line goes through the origin. If the line didn't go through the origin, then we would have to use the slope formula.

The unit rate is y/x = 9/6 = 3/2 cm per second. I used the point (9,6) to compute the unit rate.

We can think of the fraction 3/2 as 1.5, so the unit rate is equivalent to 1.5 cm/sec.

y = 3x - 1
y = x - 7
Solve with Substitution

Answers

Y = 3x -1. Y = 3x - 1
(-3) Y = x - 7. -3y = -3x + 21

-2y = 20
-2. = -2
Y = - 10

Y = 3x - 1
-10 = 3x - 1
+ 1. + 1
-9. = 3x
3. 3

-3 = x

(-3,-10)

Solution : {y,x } = { -10 , -3 }
Solve the equation [2] for the variable of y
2 . Y = x-7
Plug this in for variable y in the equation [1]
1 (x -7 ) -3x = -1
1 -2x = 6
Solve the equation [1] for the variable x
1 2x =-6
1 x= -3
By now we know this much
Y = x-7
X =-3
Use the x value to solve for y
Y= ( -3 ) -7 = -10

Work out the area of a rectangle with base, b = 20mm and perimeter, P = 42mm.

Answers

Answer:

20mm

Step-by-step explanation:

base=20mm

base x 2 because there are two long lines

20 x 2 = 40

42-40=2

amount needed on either side to balance

height=1mm

20 x 1 = 20mm

area = 20mm

Answer:

Let the length of the rectangle be 'l'

We have,

Perimeter of rectangle, P = 42mm.

[tex]or, 2(l+b) = 42\\or, l +b = \frac{42}{2} = 21\\or, l + 20 = 21\\or, l = 1mm\\[/tex]

Area of rectangle = [tex]lb = 1(20) = 20mm^{2}[/tex]
