Answer:

56g and 88g

Step-by-step explanation:

7x+11x=144

18x=144

x=144/18

x=8

7x=7*8=56g

11x=11*8=88g

Answer:

88:56 = 11:7

Step-by-step explanation:

Step One

Add the two ratios together 11 + 7 = 18

Now set up a ratio to solve for 11 parts out of 18

11:18 = x:144         Proportion

11 / 18 = x / 144    Equation: Cross mulitiply

11*144 = 18x         Combine the left side

1584   = 18x         Divide by 18

1584 / 18  = x

88 = x

That is the larger amount (11 is larger than 7)

Find the smaller amount

144 - 88 = 56

The two amounts are in the ratio of 11:7

88:56 = 11:7  

I hopes this helps a little  bit

Newton uses two properties ti rewrite the expression (4x23)x25 identify the properties he used why would Newton use these proper
valentinak56 [21]

The two properties newton used to rewrite the <em>expression </em>are;

<u><em>- Associative Property; Because it involves change of grouping of numbers in the expression.</em></u>

<u><em>- Distributive Property; Because it involves distribution of a number outside a bracket to numbers inside that same bracket.</em></u>

  • This involves algebraic <em>properties</em>. There are 3 major types that work on only addition and multiplication namely;

- Associative Property

- Commutative Property

- Distributive Property

Let us define each of them;

1) Associative Property; This property in algebra is one that means that no

matter how we group the numbers, we will still get the same result. e.g.

x + (y + z) = (x + y) + z.

2) Commutative Property; This property means that we can change the

order of <em>operation</em> and still get the same answer. For example;

p × q × r = p × r × q

3) Distributive Property; This property means that multiplying the sum of

two or more which are in a bracket by a number outside the will be equal to

the answer gotten when we multiply each number in the bracket

individually by the number outside and then adding their respective

products together. For example; p(q + r) = (p * q) + (p * r)

Newton has the expression; (4 × 23) × 25

Since it is multiplication, he can use any of the three properties above but let us use the <em>associative and distributive properties </em> as they are most suited to this expression<em>.</em>

  • For the <em><u>associative property</u></em> as shown above, he will arrive at;

(4 × 23) × 25 = 4 × (23 × 25)

  • For the <u><em>distributive property</em></u> as shown above, he will arrive at;

(4 × 23) × 25 = (25 × 4) + (25 × 23)

 y = - 4x + - 8 is equation of slope-intercept form.

What is in slope-intercept form?

  • Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form.
  • Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form.

the equation of slope - intercept form

                               y = mx + c

( -1 , -4 ) is point shown in graph

            slope = -y/x

                     = - ( -4)/-1  = 4/-1 = -4

             - 4 = -4 * - 1 + c

            - 4 = 4 + c

            c = - 4 - 4 = - 8

put value of c in the equation of slope - intercept form

             y = - 4x + - 8

Pleaseeee help me solve this
Ulleksa [173]

Answer:

3/5 is the answer!

Step-by-step explanation:

y = 3x/5 also means y = 3/5 * x

Which means in y = mx form, the 3/5 = m

Answer:

82.96

Step-by-step explanation:

area of box:

A = L^2 = (14 in.)^2 = 196 in.^2

area of pizza:

A = (pi)r^2 = 3.14 * (6 in.)^2 = 113.04 in.^2

Empty area:

196 in.^2 - 113.04 in.^2 = 82.96 in.^2
