Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

<u />\displaystyle -\frac{3}{4}x + 2 \leq -7<u />

<u />

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Subtraction Property of Equality] Isolate <em>x</em> term:                                           \displaystyle -\frac{3}{4}x \leq -9
  2. [Division Property of Equality] Isolate <em>x</em>:                                                         \displaystyle x \leq 12

Here we see that any value <em>x</em> smaller than or equal to 12 would work as a solution to the inequality.

1:320000<br> what is the actual distance represented by 1 cm <br> give your answer in km
Musya8 [376]

Answer:

1:3.2km

Step-by-step explanation:

-Given the scale 1:320000 all in centimeters.

-We need to convert the represented cm dimension into kilometers.

#We know that 1cm equals 0.00001 km.

We therefore multiplied the represented dimension by 0.00001 km:

=320000\times 0.00001 km\\\\=3.2 \ km

Hence the scale i s 1cm represents 3.2km thus 1:3.2km

I need help finding the value of x and the measure of each angle
anastassius [24]

Answer:

x=7,  angle a= 45 degrees, angle b= 65 degrees

Step-by-step explanation:

All the angles in a triangle must add up to 180. Subtract 70 from 180, add both angle a and angle b to get 16x-2=110, solve for x, x=7. Substitute x out for 7 in the equations then simplify to get angle a=45 and angle b=65

Please help me please
SVETLANKA909090 [29]

Answer: x is 125

Step-by-step explanation: Angles P and S are also consecutive angles, adding up to 180 degrees. 180-55 = 125, so adding the two angles together is 180 degrees. Thus, x is 125.

Answer:

Let's call:

f = price of 1 cup of dried fruit

a = price of 1 cup of almonds

In order to build the linear system, you need to consider that the total price of a bag is given by the sum of the price of cups times the number of cups in each bag, therefore:

Solve for a in first equation:

a = (6 - 3f) / 4

Then substitute in the second equation:

41/2 f + 6 · (6 - 3f) / 4 = 9

41/2 f + 9 - 9/2 f = 9

16 f = 0

f = 0

Now, substitute this value in the formula found for a:

a = (6 - 3·0) / 4

  = 3/2 = 1.5

Hence, the cups of dried fruit are free and 1 cup of almond costs 1.5$
