1 Step/2 Step
Solve for x
x/5=-3
x = -15
Solve for y
x = y + z
y = x-z
Which of the following equations are literal equations? Select all that apply.
A) 12x = 144
B) 3c + 6g = 9
C) A =bh
D) 5x2 - 5 = 495
B & C
Solve for x
8 = x - 9
x = 17
Solve for g
4h + g = 10
g=10-4h
Write an equation for the following statement.
Ten more than four times a number is eighteen. Find the number.
4x + 10 = 18
Solve the equation
m/3+2=8
m = 18
Solve for d
(d-a)/(c) = b
d=bc+a
Nathan solved this problem incorrectly. Describe the error he made and solve it correctly.
2x - 8 = 14
(2x)/2 - 8 = 14/2
x - 8 = 7
+8 = +8
x = 15
Nathan divided by 2 first when he needed to add 8 to both sides first. The correct answer is x = 11.
Solve the equation
-9 = -x + 3
x = 12
Solve for r
2t + 3r = 9
r = 3 - 2/3t
Solve for y and explain your steps.
(y-2)/(x)=b
First I would _____________________. Second I would ______________________.
y = bx + 2
First I would multiply both sides by x. Second I would add 2 to both sides.
Solve for x
(x-4)/(2)=10
x = 24
Solve for m
m/n-o=p
m = n(p+o)
Mr.Scarpaci wants to buy the new iPhone 17. UPS will charge Mr.Scarpaci a one time shipping fee of $9.50. UPS will also charge Mr.Scarpaci $0.20 per mile they travel to deliver the iPhone. If the total delivery cost is equal to $16.50. How many miles did UPS have to travel?
0.20m + 9.50 = 16.50
35 miles
Solve the equation
-20=5-10x
x = 2.5
Solve for b
A = 1/2bh
b=(2A)/h
The Fahrenheit and Celsius scales are related by the equation
F = 9/5 C+32
In February, the average low temperature in Buckley, Washington is 34° F. To the nearest whole number, what is this temperature in degrees Celsius?
