Joey's biking:
32/4=8 Not this one.
Jaclynn's Shopping:
24/3=8 Not this one.
Josephine's Grapes:
4/0.5=8 not this one
Jerry's Running:
2/8= .25 This one is correct

Answer:
[tex]x = 110 \\ (exterio \: angles \: of \: a \: traingle \: sum \: up \: to \: 360)[/tex]
Answer:
x = 110
Step-by-step explanation:
Assuming you require the value of x
The sum of the external angles of a triangle = 360°
The 3 angles shown are external angles.
Subtract the sum of the 2 given angles from 360 for x
x = 360 - (140 + 110) = 360 - 250 = 110
-4x+-3=-2x+-2
what is X?

Byron’s workout starts with a
warmup at home, and then he runs
at 4 mi/h. After half an hour of
running, he is 2 miles from home.
What is an equation in point-slope form that represents Byron’s
distance from home, y, after
x hours?
Answer:
An equation in point-slope form that represents Byron’s distance from home, y, after x hours is y=4x+2
Step-by-step explanation:
Speed of Byron = 4 miles / hour
Distance traveled in x hours = [tex]Speed \times time[/tex]
Distance traveled in x hours = 4x
We are given that After half an hour of running, he is 2 miles from home
So, Total distance = 4x+2
So, y = 4x+2
Hence an equation in point-slope form that represents Byron’s distance from home, y, after x hours is y=4x+2
7. Carlos is renovating a house and hires a plumber to install the piping for 4 points
the new bathroom. The plumber charges an initial fee plus an hourly rate
for the number of hours it will take to complete the installation. The
function y = 100 + 35x can be used to model the total cost of the job, in
dollars. What does the slope in the expression of this function represent? *
the initial fee for the installation, $35
the initial fee for the installation, $100
the cost per hour of installation work, $35
the number of hours to complete the installation, x
Answer:
the cost per hour of installation work, $35
Step-by-step explanation:
y = 35x + 100
the slope of a function is the coefficient of x, therefore, it is 35. $100 is the initial fee, since it ia the y intercept, and $35 is the cost per hour. y is the total amount, and x is the number of hours. Therefore, the only possible answer is the third choice,
help with this !!! thanks
Answer: Casey bought 4 1/2 pounds of apples
The equation is 0.88x - $1.50 = 2.46
x is the unknown number of pounds of apples.
0.88 is the cost per pound, 0.88x is the total cost of the apples before the discount .The discount is $1.50 $2.46 is the cost after the discount.
Part b Step-by-step explanation:
0.88x - $1.50 = 2.46 . Add $1.50 to both sides
0.88x - $1.50 + $1.50 = 2.46 + 1.50
On left, 1.50-1.50=0 so "cancels' on the right, add $2.46 + 1.50 = 3.96
0.88x = 3.96 is the cost before discount . Divide both sides by .88
.88x/.88 = 3.96/.88 . .88/.88 = 1 so 1 'cancels' leaving x. 3.96/.88 = 4.5
x = 4.5
part c
4.5 is 4 1/2, the (previously unknown) number of pounds of apples.
Casey bought 4 1/2 pounds of apples.

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each small box box of paper weighs 25 pounds and each large box of paper weighs 70 pounds. A total of 21 boxes of paper were shipped weighing 1110 pounds altogether. Write a system of equations that could be used to determine the number of small boxes shipped and the number of large boxes shipped. Define the variables that you use to write the system.
Answer:
25s+70l=1110

help ill give hella points plz thx
Answer:
Using the variables it gives us it is B=150m
Step-by-step explanation:
1.) $1800-$1350=$450
$1350 is the total balance after 3 months and $450 is the amount he has payed in those 3 months
2.) 450/3=150
You do 450/3 to find how much he is paying per month. If you want to check your work do 1800-1050=750 then do 750/5=150
So you put the numbers in B = Zachary's balance after m months and you get B=150m
Answer:
150m

3. I opened a compound interest account with $300 at 2%. How much money will be in the
account at the end of 18 months?
Answer:
there will be 408$ at the end of 18 months
Step-by-step explanation:
2% of 300 is 6 and 6 x 18 = 108. 108 + 300 = 408
Find the zeros of the function algebraically.
f(x) = 16x4 − 49x2
Answer: Plz mark me brainlest
Step-by-step explanation:
Just Simply Use Identity:
a^2 - b^2 = ( a+b) ( a-b)
Then:
( 49X^4 - 36 X^2) = 0
(7 X^2 + 6 X) ( 7X^2 - 6X) =0
7X^2 + 6X = 0, then X( 7X +6) =0 X=0, 7x +6 =0 X = -6/7
7X^2 -6x =0 X( 7x - 6) =0 X =0 7x -6 =0 X =6/7
Pull out a factor of x² from f(x) :
16x⁴ - 49x² = x² (16x² - 49)
Now write it as a difference of squares, then factorize:
16x⁴ - 49x² = x² ((4x)² - 7²)
16x⁴ - 49x² = x² (4x - 7) (4x + 7)
Set this equal to 0 and solve for x :
x² (4x - 7) (4x + 7) = 0
x² = 0 or 4x - 7 = 0 or 4x + 7 = 0
x = 0 or x = 7/4 or x = -7/4
The perimeter of a rectangle is 64 inches. Find the value of x if the width is 22 inches and tenth is 2x inches.
Answer:
5
Step-by-step explanation:
Did you mean length instead of tenth? If so, 22*2=44, 64-44=20, 20/2=10. The length of the rectangle is 10 so to find the value of x, divide 10 by 2 so, 10/2=5, and x is equal to 5. : )

6x-5 = -6(x+2)
I keep getting an incorrect fraction answer please help
Answer:
x = -7/12 or -0.583.. repeating.
Step-by-step explanation:
6x-5= -6(x+2)
___________ (distributive property)
(to group like terms)
6x-5 = -6x-12
___________ (addition poe) (add 6x on both sides to cancel -6 out)
+6x +6x
___________
12x-5 = -12
__________
+5 +5 (addition poe) (add 5 to both sides to cancel -5 out)
__________
12x = -7
__________
÷12 ÷12 (division poe) (divide both sides by 12 to get x)
x = -7/12
