if a=5, b=5 and c=8 what is 3c+bc-2a

Answer:

The answer is C

Answer:

the answer is c.......

Answer:

2

Step-by-step explanation:

To find the answer to this question, we need to add the numbers according to their place. Etc if 1 and 4 are together in a hundreds place, we add them together. If both numbers add up together results in a number bigger than 9, we have to regroup.

First, let us find the ones place.

3+5=8

Since the result is not more than 9, we do not have to regroup.

Secondly, we find the tens place.

7+6=13

Since the result is more than 9, we have to regroup.

Regrouping counter:1

Thirdly, we find the hundreds place.

8+4=12

Regrouping counter:2

Hence, your final answer is 2.

The number of times we need to group when summing 873 and 465 is 2.

During addition of two numbers, values are added based on their place values, such that digits with the same place value are added together.

The highest single value that can be obtained when summing values without needing to regroup is 9.

Hence, each time two digits are added such that the value of the sum exceeds 9, then regrouping is required.

Adding 873 + 465

H __ T __ U

8 __ 7 __ 3

4 __ 6 __ 5

(3 + 5) = 8 ( NO NEED TO REGROUP)

7 + 6 = 13 (WE NEED TO REGROUP) SUM exceed 9

(8 + 4 + 1) = 13 (WE NEED TO REGROUP) SUM exceed 9

Hence, the number of times we need to regroup is 2.

Hey there!

The points are;(4,-3) and (8,-2).

Use slope formula.

[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]

Put all values.

[tex]m = \frac{ - 2 + 3}{8 - 4} [/tex]

[tex]m = \frac{1}{4} [/tex]

Therefore, the slope is 1/2.

Answer:

D

Step-by-step explanation:

in order to compare all the numbers, we have to express them all in the same form to compare them easily, we will choose to convert all of them to decimal form:

20% = 20/100 = 0.2

1/3 = 0.33333

3.4 x 10⁻¹ = 0.34

-5/2 = -2.5

comparing all these numbers, it is now clear that in decending order:

0.34 > 0.33333 > 0.2 > -2.5

or

3.4 x 10⁻¹ > 1/3 > 20% > -5/2

(Answer D)

The number without exponent is written as,

⇒ 8pppppp

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We have to given that;

The expression is,

⇒ (2p²)³

Now, We can write the expression without exponents as;

⇒ (2p²)³

⇒ 2³ × (p²)³

⇒ 8 × p⁶

⇒ 8 × p × p × p × p × p × p

⇒ 8pppppp

Answer:

C 60

Step-by-step explanation:

This is because if you do 303+60=363 and then you do 363/11 you get 33. So x=60

60

Multiply both sides of the equation by 11:

303 + x =363

Move constant to the right side and change its sign:

x = 363 - 303

Then,subtract the numbers:

x = 60

Answer:

The rate of change is 1

Step-by-step explanation:

This is because the slope is x, and -4 is just the y-intercept, which has nothing to do with the slope. Because the slope is x, that means that it is positive 1.

Answer:

Rate of Change = 1

Step-by-step explanation:

Rate of Change = Slope = m

y = mx + b

y = (1)x -4

m = 1

Answer:

a is false, B is true,

Step-by-step explanation:A is false because the more hours you work, the more money you get.

B is true because if the volume is constant, the bigger the length, the smaller the width, or vice versa.

[tex] \sqrt{ ({ - 1 - 7})^{2} + ({2 - a})^{2} } = \sqrt{ ({ - 1 - a})^{2} + ({2 - ( - 3)})^{2} } \\ [/tex]

Bring both sides of the equation to the power of 2

[tex]( { - 8})^{2} + ({2 - a})^{2} = ({ - 1 - a})^{2} + ({2 + 3})^{2} \\ [/tex]

[tex]64 + 4 - 4a + {a}^{2} = 1 + 2a + {a}^{2} + 25 \\ [/tex]

[tex] {a}^{2} - 4a + 68 = {a}^{2} + 2a + 26 [/tex]

Subtract sides -26

[tex] {a}^{2} - 4a + 68 - 26 = {a}^{2} + 2a + 26 - 26 \\ [/tex]

[tex] {a}^{2} - 4a + 42 = {a}^{2} + 2a [/tex]

Subtract sides -a²

[tex] {a }^{2} - {a}^{2} - 4a + 42 = {a}^{2} - {a}^{2} + 2a \\ [/tex]

[tex] - 4a + 42 = 2a[/tex]

Plus sides 4a

[tex]4a - 4a + 42 = 2a + 4a[/tex]

[tex]42 = 6a[/tex]

Divided sides by 6

[tex] \frac{42}{6} = \frac{6}{6}a \\ [/tex]

[tex]a = 7[/tex]

y=4x-6

Step-by-step explanation:

The formula for y is -6+4x from the equation −4x+y=−6.

Two or more expressions with an Equal sign is called as Equation.

The given equation is −4x+y=−6

Minus four times of x plus y equal to minus six.

We need to solve the formula for y.

In the given equation x and y are the variables.

Isolate the variable y by add 4x on both sides of the equation

y=-6+4x

Hence, the formula for y is -6+4x from the equation −4x+y=−6.
