1. Simplify the following by combining like terms (5 points).
4x-10+14+7x-10x+2

Answer: 10 weeks

Step-by-step explanation:

Nilda's money = 250 +15x being x the number of weeks that have passed    

Lona's money= 200+20x

If they have the same amount, then

250+15x=200+20x

250-200=(20-15)x

50=5x

50/5=x

10=x

Answer:

10 weeks

Step-by-step explanation:

Nilda's money = 250 + 15x

Lona's money = 200 + 20x

250 + 15x = 200 + 20x

250 - 200 = (20 - 15)x

50 = 5x

10 = x

Step-by-step explanation:

Answer:

a) 35km

b) 070 degrees

Step-by-step explanation:

To get full marks look at what I did for question (c)

You have to use a protractor on letter s and make sure the 0 on the protractor is facing the letter (N). Now check where 90 degrees is and draw a line straight by using the ruler then use the compass as u can see in the photo, where (x) point is on the end of the compass is your answer {make sure the compass is 2cm which means its 20km. Also make sure to align the compass on the line you drawn}

Thank you

Step-by-step explanation:

Answer:

B.  

Step-by-step explanation:

The required expression is equivalent to the given expression is C.

An equivalent expression for 16r6sc/8r2s6 is to determine.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Numerator = it is the term positioned above in the ratio
Denominator = it is the term positioned below in the ratio

Here,  
= 16r6sc/8r2s6
Factored 16 into 8 * 2
= 8*2r6sc/8r2s6
Rearrange the numerator in order to simplify relative to denominator.
=8r2s6c/8r2s6
8r2s6 are common in the denominator and the numerator of the ratio denominator does not equal zero so it implies
=c/1

Thus the required expression is equivalent to the given expression is C.

Calculating Multipliers :

9.2    Calculate multipliers for the two fractions

   Denote the Least Common Multiple by  L.C.M

   Denote the Left Multiplier by  Left_M

   Denote the Right Multiplier by  Right_M

   Denote the Left Deniminator by  L_Deno

   Denote the Right Multiplier by  R_Deno

  Left_M = L.C.M / L_Deno = 1

  Right_M = L.C.M / R_Deno = 2

Making Equivalent Fractions :

9.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

  L. Mult. • L. Num.      837

  ——————————————————  =   ———

        L.C.M             50

  R. Mult. • R. Num.      279 • 2

  ——————————————————  =   ———————

        L.C.M               50  

Adding fractions that have a common denominator :

9.4       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

The translation of the given statement is 12 + 7n < 6.

Inequality is a form of comparing two non equal quantities.It has four types less than, less than or equal to and greater than, greater than equal to.

According to the given question we have to translate a given statement into a numerical expression.

Given, Twelve more than seven times a number equals the number less six.

Let the number be denoted by 'n'.

Twelve more than 7 times a number is 12 + 7n is less than 6.

12 + 7n < 6.

7n < 6 - 12

7n < -6

n < -6/7.
