Step-by-step explanation:

Answer: The answer is D (Mr. Johnson will earn $140 for 12 hours of work

Step-by-step explanation:

So with process of elimination we can safely say that for every hour Mr. Johnson will earn 12$.

So it is true that *A* e(amount earned)= 12h($12 made per hour)

And if *B* Mr. Johnson makes $12 per hour then in 4.5 hours he will make $54

We also know for a fact *C* Mr.Johnson earns $12 per hour

but in 12 hours Mr. Johnson will make $144 not $140 so *D* is incorrect

Answer:

Blank 1: y=3x+10

Blank 2: y= 40

Step-by-step explanation:

Let the cost of gift wrap be y and the number of gifts be x.

Department

An upfront fee of $10 means that Mr Bentley needs to pay $10 first, and this $10 is only paid once on top of the cost of wrapping each gift.

y= 3x +10

Niece

A flat fee of $40 means that no matter how many gifts the niece wraps, Mr Bentley only pays $40.

y= 40

To find out when the two plans cost the same, equate the two equations together. Then, solve for x.

3x +10= 40

3x= 40 -10 (-10 on both sides)

3x= 30

x= 30 ÷3

x= 10

Thus when Mr Bentley has 10 gifts to be wrapped, the 2 plans costs the same.

Answer:

54 centimeters

Step-by-step explanation:

Answer:

x(x-2)

Step-by-step explanation:

the common multiple here is the x, notice how it appears in both both terms. thus, we can factor it out of the equation going from x²-2x to x(x-2)

x(x-2)

Im assuming you meant x² - 2x but correct me if i'm wrong!

so x is common in both terms so you can take it out and factorise it.

Hope this helps!

Answer:

26

Step-by-step explanation:

Solve 9x-1 = 41-5x

9x-1 = 41-5x

   +1   +1

9x = 42-5x

+5x      +5x

14x = 42

/14     /14

x = 3

Plug in X for EF

41-5(3)

41-15

=26

Answer:

Step-by-step explanation:

First we must distribute the multiplier 3 over x + 4, obtaining 3x + 12.

We then have 3x + 12 = 3x + 12, or 12 = 12.  This is always true; the given equation has an infinite number of solutions.

6/10 Simplified: 3/5 of a bag

Step-by-step explanation:

One bag= 10/10

She washed 4/10

So, 10/10-4/10=6/10

6/10=3/5

3/5 of a bag

Answer:

[tex] 11.25\: {in}^{3} [/tex]

Step-by-step explanation:

Since, box contains two layers of cubes and each layer has 15 cubes.

So, length = 15*1/2 in = 7.5 in,

width = 3*1/2 in = 1.5 in

height = (1/2 + 1/2) = 1 inch

Volume of box = lbh

= 7.5* 1.5 *1

= 11.25 cubic inches

Answer:

Step-by-step explanation:

The remains two angles are 2x and 3x.

2x+3x = 360-290-20 = 50°

x= 10°

One angle is 20°. The last angle is 30°

Answer:

rotation, then translation

Step-by-step explanation:

The transformation that map triangle MNQ onto triangle PQN is rotation, then translation.

The given triangles;

A translation of a triangle occurs when the triangle shifts up, or down,  of left or right on the coordinate plane.

The reflection of a triangle occurs when the vertices of the triangle is flipped over the opposite side.

Since the triangle MNQ is rotated then shifted to the left to form the new triangle PQN, we can conclude that the transformation that map triangle MNQ onto triangle PQN is rotation, then translation.

Answer:

Slope = 3

Y intercept = 1

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept.

So in your question

-3x+y=1

add 3x to each side to get

y = 3x+1

3 is m

1 is b

so the slope is 3

the y intecept is 1

Answer:

Answer:

The vertex form of the quadratic:    y = (x - 1)² + 2

Coordinates of vertex:    (1, 2)

Step-by-step explanation:

The vertex form of an equation of the parabola is:  f(x) = a(x - h)² + k

where (h, k) is the vertex. So:

x - h = x - 1   ⇒   h = 1

+ k = +2     ⇒  k = 2                                                                                                     -------------------------------------------------------------------------------
