Tessa likes to carve bird and cat figures out of wood. She has carved 4 times as many bird figures as cat figures. If Tessa has carved 24 bird figures, how many figures has she carved altogether?

Answers

Tessa carved a total of 30 figures including bird and cat figures.

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

let, The number of cat figures is 'x'.

Given, She has carved 4 times as many bird figures as cat figures.

Therefore, 4x = 24.

x = 24/4.

x = 6.

So, Tesaa carved 6 cat figures and hence she carved a total of

24 + 6 = 30 figures.

Find a pair of numbers that have a sum of −3 and a difference of −7.

Answers

Answer:

x = -5 and y = 2

Step-by-step explanation:

You want to start by writing these two equations:

x + y = -3

and

x - y = -7

Then, you want to add the solutions to these two equations, like so:

-3 + -7 = -10

Then, to find the x value, because x > y, divide the answer by two:

-10/2 = -5

So, the x value is -5.

With this information, you can figure out that the y value is 2.

Check the answer:

-5 + 2 = -3

-5 - 2 = -7

Step-by-step explanation:

The common difference d in an arithmetic sequence is

d = a₂ - a₁ = - 1 - (- 3) = - 1 + 3 = 2

A carpenter has a wooden stick that is 84 centimeters long. She cuts off 25% from the end of
the stick. Then she cuts the remaining stick into 6 equal pieces. What is the length of each
piece?

How did you get 63?

Answers

Answer:   10.5 cm

=======================================================

Explanation:

25% = 25/100 = 0.25

25% of 84 = 0.25*84 = 21

So 21 cm has been cut off, leaving 84-21 = 63 cm left over

Or you could say that if 25% has been cut off, then 75% of the stick remains

So, 75% of 84 = 0.75*84 = 63 cm remains.

The remaining length of 63 cm is cut into 6 equal pieces

Each smaller piece is 63/6 = 10.5 cm long

Is the function an exponential function?
y=(-2)^x

Answers

Answer:Yes

Step-by-step explanation:

the normal exponential function is ab^x, where a represent the growth( sometimes you don't need this part), b is average rate of growth and x is the number of times we exponate. [tex]-2^{x}[/tex] is a exponetital function because it includes the b and x part. The a part is someetimes used but not always.

A function is a relationship between inputs where each input is related to exactly one output.

An exponential function is a function in the form

y = [tex]a^{x}[/tex]

Where a = constant and x = variable.

y = [tex](-2)^{x}[/tex] is an exponential function.

Where -2 is a constant and x is a variable.

What is a function?

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

y = [tex](-2)^{x}[/tex]

An exponential function is a function in the form

y = [tex]a^{x}[/tex]

Where a = constant and x = variable.

Example:

y = [tex]3^{x}[/tex]

y = [tex]5^{x}[/tex]

We see that,

y = [tex](-2)^{x}[/tex]

-2 is a constant

x is a variable

Thus,

y = [tex](-2)^{x}[/tex] is an exponential function.

Where -2 is a constant and x is a variable.

I need to find the missing angle thank you

Answers

Answer:

The missing angles measure is 70 degrees

Step-by-step explanation:

First we must complete the left triangles last measure:

60+65+x=180

x=55

Then we have to make all of those three middle angles equal 180:

55+50+y=180

105+y=180

y=75

Now we add 75 to 35 to the missing angle to get 180:

75+35+z=180

110+z=180

z=70
