What is the solution to the inequality 7x - 26>3 (3x-2)
Answer:
the solution to the inequality is x<-10
Answer:
x<−10
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
7x−26>9x−6
Step 2: Subtract 9x from both sides.
7x−26−9x>9x−6−9x
−2x−26>−6
Step 3: Add 26 to both sides.
−2x−26+26>−6+26
−2x>20
Step 4: Divide both sides by -2.
-2x/-2 > 20/-2
x<−10
1) x < -14
please help i don’t know how to do this
Answer: See the diagram below.
This diagram shows a closed filled in circle at -14 on the number line. Also, the shaded region is to the left of the closed circle. This visually represents values that are smaller than -14, or equal to -14.
The filled in circle is used to indicate "include this endpoint". In contrast, an open hole indicates "do not include this endpoint" which is only used if the inequality was [tex]x < -14[/tex] instead of [tex]x \le -14[/tex]. The "or equal to" portion is why we include the endpoint.

Mrs. Booker was being chased by a horde of zombies. She had to run 8 yards to make it to a safe zone. How far did she run in feet?
Answer:
24 feet
Step-by-step explanation:
Given that,
Mrs. Booker had to run 8 yards to make it to a safe zone.
We need to convert this distance in feet.
The conversion from yards to feet is as follows :
1 yard = 3 feet
So,
8 yards = 24 feet
Hence, Mrs. Booker had to run 24 feet to make it to a safe zone.
Suppose your friend's parents invest $15,000 in an account paying 7% compounded annually. What will the balance be after 10 years?
Answer:
$25,500
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year,
then, solving our equation
I = 15000 × 0.07 × 10 = 10500
I = $ 10,500.00
The simple interest accumulated
on a principal of $ 15,000.00
at a rate of 7% per year
for 10 years is $ 10,500.00.

finding x - cicrle theorems
Answer:
x = 30
Step-by-step explanation:
AB is a tangent to the circle so ∠ ABO = 90°
The sum of the 3 angles in a triangle = 180° , then
x + 2x + 90 = 180
3x + 90 = 180 ( subtract 90 from both sides )
3x = 90 ( divide both sides by 3 )
x = 30
Answer: x = 30
OA cuts the circle (O) at C
because ∠ABC is the angle created by tangent rays and chord
=> ∠ABC = 1/2.∠AOB = 1/2.2x = x
ΔOBC has OB = OC (are both radii)
=> ΔOBC is the isosceles triangle at O
=> ∠OCB = (180° - ∠COB)/2 = (180° - 2x)/2 = 90° - x
because ∠OCB is the outer angle of ΔABC
=> ∠OCB = ∠ABC + ∠CAB
⇔ 90° - x = x + x
⇔ 90 = 3x
⇔ x = 30

ZA and ZB are supplementary angles. If mZA = (x + 6) and m
ZB = (7x +30)°, then find the measure of ZA.
Answer:
za=24
Step-by-step explanation:
supplementary angles add up to equal 180
180=7x+x+30+6
step 1 combine like terms
180=8x+36
step 2 subtract 36 from each side
144=8x
step 3 divide each side by 8
x=18
now we just plug in 18 to x in x+6
18+6=24
Answer:
24°
Step-by-step explanation:
The sum of supplementary angles is 180°.
Thus, we can set up our equation as:
(x + 6) + (7x + 30) = 180
Combine like terms.
8x + 36 = 180
Isolate the variable by subtracting 36 from both sides.
8x = 144
Divide both sides by 8.
x = 18
Now, let's revisit the equation for m∠ZA, and plug in our x.
((18) + 6)°

The following information is known about a loan.
Time = 7 years
Interest rate = 6%
Interest = $840.00
What was the principal on the loan?
$200.00
$352.8ghing
$1.862.50
O $2.000.00
Answer:
B. $352.80
Step-by-step explanation:
edge 2021
The principal on the loan with interest rate of 6% is $2000.
Given that a loan is given in the interest rate of 6%, interest received is $840 and the duration of the loan is 7 years,
We need to find the principal on the loan,
To find the principal on the loan, we can use the formula for simple interest:
Interest = Principal × Rate × Time
In this case, we know the interest is $840.00, the rate is 6%, and the time is 7 years.
Let's solve for the principal:
Principal = Interest / (Rate × Time)
Principal = $840.00 / (0.06 × 7)
Principal ≈ $840.00 / 0.42
Principal ≈ $2000.00
Therefore, the principal on the loan is $2000.00.

Is 6x and 4x+2 equivalent
Answer:
Is 6x and 4x+2 equivalent
? No!
Step-by-step explanation:
6x doesn't equal 4x+2
In order for them to be the same you would have to add the same terms example:
4x+2x would equal 6x
Extra explaining:
The only way for those term to be added would be if they had the same variable since only 4x has a variable the 2 cant be added. In math you CANNOT move your variables off of a number and add them back on after.
