1. Solve each equation. a. 4x = -28 b. x - -6 = -2 C.-Y + 4 = -9 d. -3x + 7 = 1 e 25% -11 = -86
Answer:
A,-7
B, 4
C,13
D,2
Step-by-step explanation:
A,Step 1: Divide both sides by 4.
[tex] \frac{4x}{4} = \frac{ - 28}{4} [/tex]
[tex] x = - 7[/tex]
B,Step 1: Add 6 to both sides.
x−6+6=−2+6
x = 4
C, Step 1: Regroup terms.
4−Y=−9
Step 2: Subtract 44 from both sides.
-Y=-9-4−Y=−9−4
Step 3:Simplify -9-4−9−4 to -13−13.
[tex] \frac{ - y}{1} = \frac{ - 13}{ - 1} [/tex]
Y = 13
D,Subtract 77 from both sides.
-3x=1-7−3x=1−7
2, Simplify 1-71−7 to -6−6.
-3x=-6−3x=−6
3,Divide both sides by −3.
[tex] x = \frac{ - 6}{ - 3} [/tex]
4,Two negatives make a positive.
x = 6/3
x = 2.

The sales tax on a $750 computer at T&C Computers is $75. What is the sales tax rate? BTW
ANSWER IS 10%
Answer:
10%
Step-by-step explanation:
Price of computer = $750
Amount of sales tax = $75
Sales tax rate = Amount of sales tax / Price of computer × 100
= $75 / $750 × 100
= 0.1 × 100
= 10%
Sales tax rate = 10%
Sales tax rate = 10% of selling price
the area of the retangler piece of foil is 11 1/4 square inches its length is 4 1/2 inches what is the width of the foil?
Answer:
The width of the foil = w = 2.5 inches
Step-by-step explanation:
We know that the Area of a rectangular piece:
[tex]A=wl[/tex]
Here:
'w' is the width 'l' is the lengthGiven that area of the rectangular piece of foil:
Area = A = 11 1/4 square inches
= 45/4 square inches
= 11.25 square inches
Length = l = 4 1/2 inches
= 9/2 inches
= 4.5 inches
Using the Area formula
[tex]A=wl[/tex]
[tex]w\:=\:\frac{A}{l}[/tex]
[tex]=\frac{11.25}{4.5}[/tex]
[tex]= 2.5[/tex] inches
Thus, the width of the foil = w = 2.5 inches

What is 21=14+7x I need help
Answer:
x-1
Step-by-step explanation:
The solution to the equation 21 = 14 + 7x is x = 1.
What is the solution to the equation?Given the equation in the question:
21 = 14 + 7x
To solve the equation 21 = 14 + 7x, start by isolating the variable x to one side of the equation:
21 = 14 + 7x
Subtract 14 from both sides of the equation:
21 - 14 = 14 - 14 + 7x
Add 14 and -14:
21 - 14 = 7x
Subtract 14 from 21:
7 = 7x
Reorder the equation:
7x = 7
Divide both sides by 7:
7x/7 = 7/7
x = 7/7
x = 1
Therefore, the value of x is 1.

richard and teo have a combined age of 42 richard is 12 years older than twos age how old are richard and teo
Answer:
teo= 15 years old
richard= 27 years old
Step-by-step explanation:
richard=r
teo=t
r + t=42
t + 12= r
u can use substitution here
(t+12) + t=42
2t + 12= 42
2t=30
t= 15
to find r, you just do 15 + 12= 27
to check you can do 27 + 15= 42
The age of Richard and Teo will be 27 years and 15 years, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Richard and Teo are 42 years old. Richard is 12 years older than Teo.
Let x be the age of Richard and y be the age of Teo. Then the equation is given as,
x + y = 42 ...1
x = y + 12 ...2
From equations 1 and 2, then we have
y + 12 + y = 42
2y = 30
y = 15
Then the value of the variable 'x' is given as,
x = 15 + 12
x = 27
The age of Richard and Teo will be 27 years and 15 years, respectively.

Determine the measure of the unknown angle in the triangle.
you add 78 plus 37 then subtract from 180
Answer:
65°
Step-by-step explanation:
Let the unknown angle be ∠ABC
∠ABC + 78° + 37° = 180° (angle sum property of a triangle)
∠ABC + 115° = 180°
∠ABC = 180° - 115°
∠ABC = 65°
∴the unknown angle in the triangle is 65°

One week, Ellie earned $72.50 at her job when she worked for 5 hours. If she is paid
the same hourly wage, how many hours would she have to work the next week to earn
$232.00?
Answer:
The corect answer is 16.
Step-by-step explanation:
$ 72.50 per 5 hours = $14.50 per hour ....
because 72.50 ÷ 5 = 14.50
THEN
$232.00 ÷ $14.50 (in other words→23200 ÷ 1450) = 16
