Answer:

36

Step-by-step explanation:

the first sequence starts

4 12 (3*4) 36 (3*12) 108 (3*36) ...

the second sequence starts

20 28 (8+20) 36 (8+28) 44 (8+36) ...

so, just by writing down a few elements you can see it already.

I knew it already before that just by thinking "the first sequence has only numbers that can be divided by 3. what is the first number of the second sequence that can be also divided by 3 ? oh, yeah, 36 !"

Evaluate the expression. [(8 x 7) – 2): 9​
frozen [14]

Answer:

☑ Answer is 6

Step-by-step explanation:

{ \tt{ \{(8 \times 7) - 2 \} : 9}} \\  = { \tt{(56 - 2) :9 }} \\  = { \tt{54 :9 }}

» But this is a ratio, so it can be expressed in terms of fractions:

= { \tt{ \frac{54}{9} }} \\

» Divide both the denominator and numerator by 9:

{ \tt{ =  \frac{54 \div 9}{9 \div 9} }} \\  \\  = { \tt{ \frac{6}{1} }} \\  \\  = 6

Write a linear equation in standard form that satisfies the given set of conditions. X-intercept: 3, y-intercept: 5
Artyom0805 [142]

The linear equation in standard form is y=\frac{-5}{3}x +5.

<h3>Linear Function</h3>

An equation can be represented by a linear function. The standard form for the linear equation is: ax+b , for example, y=7x+2. Where:

a= the slope. It can be calculated for  \frac{\Delta x }{\Delta y}.

b= the constant term that represents the y-intercept.

The question gives: X-intercept:3  and  y-intercept: 5. Then,

  • The x-intercept is the point that y=0, then the x-intercept point is (3,0).
  • The y-intercept is the point that x=0, then the x-intercept point is (0,5).

With this information, you can find the slope (a).

a=\frac{\Delta y }{\Delta x}= \frac{0-5}{3-0} =\frac{-5}{3}

The question gives the coefficient b since it gives the y-intercept=5.

Therefore the linear equation is : y=\frac{-5}{3}x +5.

Find the sum of a finite geometric series.
NNADVOKAT [17]

Answer: 17 in.

Step-by-step explanation:

The sides of an equilateral triangle measure 16 inches. The midpoints of the sides of the triangle are joined to form another equilateral triangle with sides that are half the length of the outer triangle. This process is continued until three triangles are inscribed in the first triangle. The sum of the perimeters of all four triangles is 17 in.

Pleas help with the ones you understand

For 1- 4 all you have to do is multiply the numbers.

An easier way to write the same equation out would be to add multiplication signs. For example:

1. -2*3 is the same as (-2)(3)

When there are two parentheses next to each other without a sign in between, that means multiplication.

6-9 can also all be converted to be  a whole number, which is what it want you to do.

11 and 12 is where you need to multiply and then add or subtract after you multiply.

Also, for 13 and 14, both the fractions can be converted to be a whole number, so you should turn them into whole numbers first and your life will be a lot easier.

And 15 is also the same thing as 11 and 12.

Extra Help: When you have two negative numbers, the answer will end being a positive and when there are two positive it will remain a positive, and a negative and positive number will be a negative.
