Answer:
There are 35 students in his class.
Step-by-step explanation:
1. Create a proportion: 60/100=21/x
2. Cross multiply, or not (I prefer to cross multiply). 60x=2100
3. Solve the equation: x=35.
Answer: There are 35 students in his class, 14 people going in school, 21 student online.
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

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
What is the greatest 3/5 0.7
Answer: 0.7
Step-by-step explanation: 3/5 equals 0.6 which is less than 0.7, so 0.7 is the greater of the two.
What is the value of x?
Answer:
10
Step-by-step explanation:
5x - 17 = 3x + 3 (vertically opposite angles)
5x - 3x = 3 + 17
2x = 20
x = 20/2
x = 10

Which of the following scenarios does not have a unit rate of 8?
O Joey rides his bike at a constant rate for 4 hours, x, and travels a total distance of 32 miles.
Jaclynn buys 3 pairs of socks, X, and spends a total of $24.
O Josephine buys 0.5 pounds of grapes, x, for $4.00.
O Jerry ran at a constant rate for 8 minutes, x, and traveled 2 miles.
Answer:
Jerry's Running
Step-by-step explanation:
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
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
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.

PLEASE HELP ME!!! -3x + 12 < 18
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

sin^2x + sin^2x + cos²x
Answer:
Answer:
A. 2 sinx cosx - 1 + 2 sin^2 x.
Step-by-step explanation:
sin2x = 2 sinx cosx
cos2x = cos^2x - sin^2x
So sin2x - cos2x = 2 sinx cosx - ( cos^2x - sin^2x)
But cos^2 x = 1 - sin^2 x, so we have:
2 sinx cosx - (1 - sin^2 x - sin^2x)
= 2 sinx cosx - 1 + 2 sin^2 x.
