b-74 = 12
explain your thinking

Answers

Answer 1

Answer:

86

Step-by-step explanation:

Step 1: Collect liketerms by switching to the terms tgat are alike to the other side

b=12+74

NOTE: while switching, the signs change to the oppositeStep 2: Add 12 + 74

b=12+74

b=86

Answer 2

Answer:

B=86

Step-by-step explanation:

So first step is add 74 to 12 because if you subtracted b with 74 and to reverse that you have to add and 74+12=86 and that is what b equals

Answers

Answer:

Step-by-step explanation:

The distance between from Math building to history building is 5 units

What is Distance Formula?

The distance between coordinate P(x , y) and coordinate Q(a , b) is calculated using the distance formula:  d= √(x-a)²+(y-b)²

The Math building is located at the point (1,5)

The History building is located at (4,9).

Using distance formula:

d= √(x-a)²+(y-b)²

  =√(4-1)²+(9-5)²

  = √9+16

  = √25

 = 5 units

Hence, the distance between Math and History building is 5 units.

is Justin went shopping for school clothes if the item cost $150 and he received a 10% discount what is the final price of his purchase​

Answers

Answer:

$135

Step-by-step explanation:

We can answer this by multiplying $150 by (1.00 - 0.10), or by 0.90:

0.90($150) = $135.

Note that 1.00($150) = $150 (full price)

and that 0.10($150) = $15 (discount)

and that (0.90)($150 = $135 (the fastest way to calculate the final (sale) price.

Emily is observing the velocity of a cyclist at different times. After four hours, the velocity of the cyclist is 14 km/h. After nine hours, the velocity of the cyclist is 4 km/h

Part A: Write an equation in two variables in the standard form that can be used to describe the velocity of the cyclist different times. Show your work and define the variables used.

Part B: How can you graph the equations obtained in Part A for the first 10 hours?

Answers

Emily starts from rest so that the velocity is zero at 0 hours.

Define the function v(t) for velocity in km/h, and t in hours.

Part A
From t=0 to t=4, v changes from 0 to 14.
Let v(t) = mt + b
The slope is
m = 14/4 = 3.5, and the y-intercept is
b = 0.
Therefore
v(t) = 3.5t, for 0 ≤ t ≤ 4

Fromt=4 to t=9, changes from 14 to 4.
Let v(t) = mt + b
The slope is
m = (4 - 14)/(9 - 4) = -2
Therefore
v = -2t + b
When t=4, v=14, therefore
14 = -2*4 + b = -8 + b
22 = b
v(t) = -2t + 22, for 4 < t ≤ 9.

Answer:
The equation for the velocity is
v(t) = 3.5t, 0 ≤ t ≤ 4
= -2t + 22, 4 < t ≤ 9

Part B
The equation for velocity is a piecewise function that is graphed as shown below. If we assume that the second part of the equation is valid at t=10, then
v(10) = -2*10 + 22 = 2 km/h

it wants us to solve for x and i’m very confused

x= ?

Answers

Answer:

x = 6

Step-by-step explanation:

∡J = ∡K and ∡M = ∡L

because this is an isosceles trapezoid

∡J + ∡M = 180°

because angles at opposite bases are supplementary

then ∡J + ∡M = 180°

∡J = (7x + 2)°

∡M = ∡L = (25x - 14)°

so:

(7x + 2 + 25x - 14)° = 180°

(32x - 12)° = 180°

32x = 180 + 12

32x = 192

x = 6

Answer:

x= 8/9

Step-by-step explanation:

7x + 2 = 25x - 14

-7x         -7x

2 = 18x - 14

+14       +14

16 = 18x

In given triangle, using this formula, we get
