Aisha has 3 pizzas. She is serving each person at a party 14 of a pizza. How many people can she serve at the party? Use the number line to help you solve the problem.[ Please help TwT]
Given:
Aisha has 3 pizzas.
She is serving each person at a party 1/4 of a pizza.
To find:
The number of people she can serve at the party.
Solution:
Let the number of people be x.
Number of pizzas is 3. So, each person get [tex]\dfrac{3}{x}[/tex] part of pizza.
It is given that each person get 1/4 of a pizza.
[tex]\dfrac{1}{4}=\dfrac{3}{x}[/tex]
Using cross multiplication, we get
[tex]1\times x=3\times 4[/tex]
[tex]x=12[/tex]
Therefore, the number of persons in 12.
Now, divide the number line in four equal parts between each pair of consecutive integers.
Then, count the marked points from 0 to 3 excluding 0. These points represent number of persons.

Step-by-step explanation:
Find the equation. You find the gradient by using the gradient formula (rise/run)
that would be
1600 - 800 over 40 - 20
800/20
m (gradient) = 40
Hence 40x ...
Answer:
See below
Step-by-step explanation:
Refer to attached
Using two of the points to determine the function:
(20, 800), (40, 1600)Function is:
y = mx + bFinding m and b:
m = (1600 - 800)/(40-20) = 800/20 = 40800 = 40*20 + bb = 0So the function is:
y = 40xFor x = 50, we get
y = 40*50 = 200050 l diesel costs $2000
if 1 and -3 are the zeroes of the polynomial xcube - axsquare - 13x + b find the values of a and b
Step-by-step explanation:
f(x) = x³ - ax² - 13x + b.
f(1) = 1³ - a(1)² - 13(1) + b = 0
=> 1 - a - 13 + b = 0, b - a - 12 = 0.
f(-3) = (-3)³ - a(-3)² - 13(-3) + b = 0
=> - 27 - 9a + 39 + b = 0, 12 - 9a + b = 0.
Therefore, b - a - 12 = 12 - 9a + b. 8a = 24, a = 3.
=> b - (3) - 12 = 0, b = 15.

Sakura buys some softballs at $3 each and bats at $35 each for her PE class.
She buys twice as many balls as bats. She spends $131 in total, which
includes $8 tax. Which equation would you use to find the number of bats she
buys?
Let x represent the number of bats she buys.
Given :
Cost of each ball , $3.
Cost of each bat , $35 .
Total money spend , $131 .
She buys twice as many balls as bats.
Tax , $8 .
To Find :
The number of bats she buys .
Solution :
Let , x represent the number of bats she buys.
So , number of balls she buys is 2x .
[tex]35x+3(2x)+8=131\\\\35x+6x=123\\\\41x=123\\\\x=3[/tex]
Therefore , number of bats she buys is 3 .
Hence , this is the required solution .
Answer:
Cost of each ball , $3.

If f(x) = 4x + 8 and g(x) = \/x + 4,
what is (fºg)(12)?
Answer: 24
Step-by-step explanation:
(fºg)(12) would be f(g(12))
Plug in 12 for g(x) = square root of (12+4) = 4
Plug 4 in f(x)
f(4) = 16 + 8

If BC = 35 and AC =52 , find AB
Answer:
AB = 47 (answers may vary)
Step-by-step explanation:
BC = 35
AC = 52
C, in fact, can be any number you choose less than 35;
For example,
C= 20
35 - 20 = 15
B = 15
52 - 20 = 32
A = 32
AB = 32 + 15 = 47
