Answer:

9

Step-by-step explanation:

From the question,

We are to evaluate the expression : 2a + b - 3 when a=5 and b=2.

We substitute 5 for a and 2 for b in the given expression

2a + b - 3

= 2(5) + 2 - 3

= 10 + 2 - 3

= 12 - 3

= 9

Answer:

$25 an hour

Step-by-step explanation:

use this equation y = hx + 50

y is the money earned and x is the hours worked

plug in 100 for y and 2 for x

100 = 2h + 50

solve for h

50 = 2h

25 = h

he charges $25 an hour

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

x + 5 = -3

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that -3 does indeed equal -3.

∴ x = -8 is the solution to the equation.

Answer:

[tex]x=-8[/tex]

Step-by-step explanation:

Subtract 5 from both sides.

[tex]x=-3-5[/tex]

Simplify [tex]-3 -5[/tex] to [tex]-8[/tex]

[tex]x=-8[/tex]

let check if the answer is correct

[tex]x+5=-3[/tex]

Let [tex]x=-8[/tex]

[tex]-8+5=-3[/tex]

Simplify [tex]-8+5[/tex] to [tex]-3[/tex]

[tex]-3=-3[/tex]

Answer:

9 inches

Step-by-step explanation:

The disks of polish kielbasa measure to be 1/4 of a inch. If there are 36 disks altogether, what is the total length of polish keilbasa being using?

The total length of polish kielbasa is calculated as:

1/4 of 36 disks

= 1/4 × 36 disks

= 9 inches

The total length of polish keilbasa being used is 9 inches

Answer:

x = [tex]-\frac{75}{32}[/tex]

Step-by-step explanation:

10 = [tex]\frac{95}{2}[/tex] + [tex]4^{2}[/tex] * x

10 = [tex]\frac{5 * 19 }{2}[/tex] + ([tex]2^{2}[/tex])²x

10 = [tex]\frac{5 * 19 }{2}[/tex] + [tex]2^{2*2}[/tex] * x

x = [tex]-\frac{75}{32}[/tex]

Answer:

75.4

Step-by-step explanation:

v = pi * r^2 * h

v = 3.14 * 4 * 6

v= 3.14 * 24

v= 75.36 m^3

to the nearest tenth is 75.4 m^3

Answer:

its 28 - 12

Step-by-step explanation:

so basically what u do is u multiply 4x7 and thats 28

and then u multiply 4x3 and thats 12

then when u subtract 28 - 12 u get 16

whiich would be the answer to the problem if u were to solve it

Answer:

[tex]\begin{array}{| c | c |}\cline{1-2} x & y\\\cline{1-2} -3 & 0\\\cline{1-2} -2 & 1\\\cline{1-2} -1 & 2\\\cline{1-2} 0 & 3\\\cline{1-2} 1 & 4\\\cline{1-2} 2 & 5\\\cline{1-2}\end{array}[/tex]

non-proportional

Step-by-step explanation:

Given equation:

[tex]y=x+3[/tex]

Create a table of ordered pairs using the given equation:

[tex]\begin{array}{| c | c | c |}\cline{1-3} x & x+3 & y\\\cline{1-3} -3 & -3+3 & 0\\\cline{1-3} -2 & -2+3 & 1\\\cline{1-3} -1 & -1+3 & 2\\\cline{1-3} 0 & 0+3 & 3\\\cline{1-3} 1 & 1+3 & 4\\\cline{1-3} 2 & 2+3 & 5\\\cline{1-3}\end{array} \implies \begin{array}{| c | c |}\cline{1-2} x & y\\\cline{1-2} -3 & 0\\\cline{1-2} -2 & 1\\\cline{1-2} -1 & 2\\\cline{1-2} 0 & 3\\\cline{1-2} 1 & 4\\\cline{1-2} 2 & 5\\\cline{1-2}\end{array}[/tex]

Graph

As the given equation is linear, plot two of the ordered pairs and draw a straight line through them.  (See attachment).

Proportional Relationship

A relationship in which two quantities vary directly with each other.

y varies directly as x:

[tex]y=kx[/tex]

(where k is some constant)

To find if the relationship is proportional using the table, find the ratio  [tex]\dfrac{y}{x}[/tex] of each row. If the ratio is the same, the relationship is proportional.

[tex]\begin{array}{| c | c | c |}\cline{1-3} x & y & \dfrac{y}{x}\\\cline{1-3} -3 & 0 & 0\\\cline{1-3} -2 & 1 & -0.5} \\\cline{1-3} -1 & 2 & -2 \\\cline{1-3} 0 & 3 & \text{-}\\\cline{1-3} 1 & 4 & 4\\\cline{1-3} 2 & 5 & 2.5\\\cline{1-3}\end{array}[/tex]

Graphs of proportional relationships pass through the origin (0, 0).

Therefore, the relationship is non-proportional because:

Answer:

1 out of ten

Step-by-step explanation:

so if there are ten sides and all are numbered 1-10 then 5 is only one tenth.

Answer:

No.

Step-by-step explanation:

Use a vertical line test.

Vertical line test: If you can draw a vertical line and it does not cross two points in the line, then it is a function.

So, we draw a line.

Draw it through 9,0

It intercepts two points so No. This is not a function.

Step-by-step explanation:

The formula for area of a rectangle is A= length times width. They gave you the area of the entire rectangle. But because this is a shape with a cutout, you still need the area of the missing section.

A= 1*4 = 4 units

Now subtract that from 49.

A=49 - 4= 45 square units

Answer:

49-4 = 45

Answer:

126

Step-by-step explanation:

Answer:

y-value = 8

Step-by-step explanation:

1/3x + 1/4y = 1 is the same as 4/12x + 3/12y = 1

which is the same as (4x + 3y)/12 = 1

which is the same as 4x + 3y = 12

add both equations and the 'y' will cancel and you will have 6x = -18

x = -3

2(-3) - 3y = -30

-6 - 3y = -30

-3y = -24

y = 8

Answer:8

Step-by-step explanation:

t = 12r/(r+120)

t(r+120) = 120r

tr+120t = 120r

tr-120r = -120t

r(t-120) = -120t

r = -120t/(t-120)

r = 120t/(120-t)

Answer: -15=x

Step-by-step explanation: subtract 10 on each side then divide -5 on both sides to isolate the variable

-5x=+10-85

5x=-75

x=-75/5=> x= -15
