Answer:

associative property

Step-by-step explanation:

we know that

According to the <u>associative property</u> of the sum, the sum of three or more numbers remains the same independently of how the numbers are grouped

so

a+(b+c)=(a+b)+c

In this problem we have that

16+(70+8)=(16+70)+8 ----> by associative property of the sum

What is a scale factor?
Blababa [14]

Answer:

Here is some helpful information from my mini lessons.

Step-by-step explanation:

If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles shown are similar, compare their corresponding sides. Here you'll learn that the ratio of the perimeters of similar figures is equal to their scale factor and that the ratio of their areas is equal to the square of their scale factor. If two polygons are similar, then the ratio of the lengths of any two corresponding sides is called the scale factor. This means that the ratio of all parts of a polygon is the same as the ratio of the sides.

Solve the following system of equations by the substitution method.
ruslelena [56]
5x = y + 6 (I)
2x - 3y = 4 (II)
-------------------
We have:
5x = y + 6 → x =  \frac{y+6}{5}

Soon:
2x - 3y = 4 → 2* (\frac{y+6}{5}) - 3y = 4\to \frac{2y+12}{5} - 3y = 4
<span>least common multiple (5)
</span>\frac{2y+12}{5} - 3y = 4\to \frac{2y+12}{\diagup\!\!\!\!\!5} - \frac{15y}{\diagup\!\!\!\!\!5} = \frac{20}{\diagup\!\!\!\!\!5}
2y + 12 - 15y = 20
- 15y + 2y = 20 - 12
- 13y = 8
\boxed{\boxed{y = - \frac{8}{13} }}\end{array}}\qquad\quad\checkmark

Fudgin [204]

The value of a and b in terms of equation are; a = 3 + b and b = a + 18.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

We are given polynomial, h(t) = 2t - at + bt + 4 represents Mr. Bill's height in metres at 't seconds. "-Mr." Bill is rapidly approaching a tall brick wall which is 100 metres high and will reach the wall in 3 seconds.

h = 100 metres

t = 3 seconds

Now substitute the values;

h(t) = 2t - at + bt + 4

100 = 2(3) - a(3) + b(3) + 4

100 = 6 - 3a + 3b + 4

3a + 90 = 3b

We need to find out if Mr. Bill will clear the wall or slam into it!

h(t) = 2t - at + bt+4 has a remainder of 9 when divided by (t-1) and a remainder of "-36" when divided by (t+2).

When t = 1

Then;

h(t) = 2t - at + bt + 4

9 = 2(1) - a(1) + b(1) + 4

9 = 6 - a + b

a = 3 + b

When time t = -2

Then; h(t) = 2t - at + bt + 4

-36= 2(-2) - a(-2) + b(-2) + 4

-36 = -4 + 2a - 2b + 4

-18 = a - b

b = a + 18
