Answer:

Step-by-step explanation:

-3(x+7)=5

1. Multiply 3 and x+7 , you will get -3x-21=5

2. Add 21 on both sides, you will be left with -3x=26

3. Divide both sides with -3, and x will equal to -26/3

Answer:

28 learners

Step-by-step explanation:

Boys : Girls

3 : 4

Since there are 12 boys and 3 units of them...

3 units = 12

1 unit = 12 ÷ 3 = 4

Girls =

4 units = 4 x 4 = 16

Total number of girls and boys: 12 + 16 = 28

Step-by-step explanation:

I believe it is 15...all the numbers can be divided by 15, since 15 is the smallest number it is also the highest common factor only because 30 and 45 can be divided by 15

.......hope it helps!

Answer:

15

Step-by-step explanation:

Find the prime factors for each number as:

45 =3 × 3 × 5

30 = 2 × 3 × 5

15 = 3 × 5

Now identify the common factors and determine the GCF:

Therefore:

HCF = 3 × 5 = 15

Answer:

$2,025

Step-by-step explanation:

The monthly payment will be increased by $‭2,025‬.

The quantity of money anyone has is termed as the amount. Your monthly payment based on the rate of 6.3% per annum is:

= (6.3% * 1,620,000 ) / 12 months

= 102,060‬ / 12

= $‭8,505‬

Now that the rate has gone up to 7.8% per annum, the payment is:

=  (7.8% * 1,620,000 ) / 12 months

= ‭126,360‬ / 12

= $‭10,530‬

Payment went up by:

= ‭10,530‬ - 8,505

= $‭2,025‬

Therefore the monthly payment will be increased by $‭2,025‬.

Answer:

Rate = 10%

Step-by-step explanation:

Given:

Amount deposit = 25,000

Amount get = 26,250

Time = 6 month = 6 / 12 = 0.5 year

Find:

Rate

Computation:

Interest = Amount get - Amount deposit

Interest = 26,250 - 25,000

Interest = 1,250

Interest = P x R% x T

1,250 = 25,000 x R% x 0.5

Rate = 10%

Answer:

algebraic expression: 3x + 2b

coefficients: 3 and 2

variables: w and b

# of terms: 2

constant: 0

algebraic expression: 6xy - 2c + 4

variables: x, y, and c

# of terms: 3

constant: 4

algebraic expression: 2/3 y - 3p

coefficients: 2/3 and -3

variables: y and p

# of terms: 2

constant: 0

Answer:

Problem 1:

Coefficients are : 3 & 2

Variables are: w & b

Number of terms: 2

Constant: none

Problem 2:

Coefficients are : 6 & -2

Variables are: xy & c

Number of terms: 3

Constant: 4

Problem 3:

Coefficients are : [tex]\frac{2}{3}[/tex] & -3

Variables are: y & p

Number of terms: 2

Constant: none

Step-by-step explanation:

Okay, lets break this down.

An Algebraic expression is not meant to be solved, but rather used to determine the various components inside of it to better understand how to solve equations later on. Although for now lets look at these problems. :

A Coefficient in terms of algebra, is the number before a variable. In other terms, a coeffiecient is the number before the letter such as 3w. Looking at 3w we see that there are two parts: 3, and w.

The number 3 is the coefficient while the variable is the letter w. Variables are always the letters.

Variable: A letter used to determine an unknown value such as x

Now a term is a single mathematical expression. It may be a single number (positive or negative), or a single variable ( a letter). (Can also be a coeffient with a variable multiplied or divided by one another as such :

[tex]3w = 3*w\\\frac{3}{w} = 3 / w[/tex]

 Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.

Now with that said, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in "x + 5 = 9", 5 and 9 are constants.

With all of that said, lets look at the problems given:

Problem 1:

Coefficients are : 3 & 2

Variables are: w & b

Number of terms: 2

Constant: none

Problem 2:

Coefficients are : 6 & -2

Variables are: xy & c

Number of terms: 3

Constant: 4

Problem 3:

Coefficients are : [tex]\frac{2}{3}[/tex] & -3

Variables are: y & p

Number of terms: 2

Constant: none

Answer:

2976 in³

Step-by-step explanation:

Stool volume = upper smaller prism + Lower bigger prism

Stool volume = 8 x 6 x 12 + 20 x 12 x 10 = 576 + 2400 = 2976

check: volume = 20 x 12 x 16 - 12 x 12 x 6 = 2976

Answer:

The mean number of lessons for group A is greater than the mean for group B by 1 MAD

Step-by-step explanation:

Given the table :

_______Mean number of lessons ____ MAD

GRP A _____ 5 ___________________ 2

GRP B _____ 3 ___________________ 2

With group A having a mean number of lessons of 5 and Group B having a mean number of lessons of 3

Mean of A > mean of B ; hence, Group A dlgs tool more lessons to learn the trick than group B dogs.

The mean absolute deviation (MAD), measures how far a value is from the mean

Difference in mean number of lessons :

5 - 3 = 2

2 lessons ;

Number of mean absolute deviations:

Difference / MAD value = 2 / 2 = 1

Answer:

The mean number of lessons for group A is greater than the mean for group B by 1 MAD.
