Answer:
x=-7
Step-by-step explanation:
Alrighty. 5x+8=2x-13. Lets do -2x on both sides. We'll get 3x+8=-13. Then lets subtract 8 from both sides. We'll get 3x=-21. Divide by 3 and we'll get x=-7. Hope that makes sense.

convert it and find its speed
in m/s
Answer:
car covers distance of 450 km in 4hr and 30min
4hr and 30 min - (4*60)+ 30 equal to 270
distance covered by car in one minute equal to 450/270 equal to 1.6 km
speed of car equal to (1.6*60)/60 equal to 1.6 km /hr
What is the solution to 8x - 3(2x - 4) = 3(x - 6)?
A.30
B.2
C.6
D.No solution
Answer: A.30
Step-by-step explanation:
Let's solve your equation step-by-step.
8x−3(2x−4)=3(x−6)
Step 1: Simplify both sides of the equation.
8x−3(2x−4)=3(x−6)
8x+(−3)(2x)+(−3)(−4)=(3)(x)+(3)(−6)(Distribute)
8x+−6x+12=3x+−18
(8x+−6x)+(12)=3x−18(Combine Like Terms)
2x+12=3x−18
2x+12=3x−18
Step 2: Subtract 3x from both sides.
2x+12−3x=3x−18−3x
−x+12=−18
Step 3: Subtract 12 from both sides.
−x+12−12=−18−12
−x=−30
Step 4: Divide both sides by -1.
−x/-1 = -30/-1
x=30Whats the slope of the table help pls

Y varies inversely with x, if y = -12 when x = 8 what is x when y = -9
Answer:
either 5 or 11
Step-by-step explanation:
(8, -12)
(5, -9) or (11, -9)
If y varies consistently with x then it would copy what happens, in a manner of speaking.
In this case, y increases by three, x would either add 3 or subtract 3
I am not completely sure on this.
Solve for x:
- 3x – 9= - 1
Answer:
- 8 / 3
Step-by-step explanation:
-3x= - 1 + 9
-3x = 8
x= - 8/3

Step-by-step explanation:
A die has 6 faces with numbers 1, 2, 3, 4, 5, 6.
The faces that are less than 3 are 1, 2.
2 faces have numbers less than 2.
The desired outcome can happen 2 ways, 1 or 2.
The total number of possible outcomes is 6: 1, 2, 3, 4, 5, or 6.
p(event) = (number of desired outcomes)/(total number of possible outcomes)
p(less than 3) = 2/6 = 1/3
The probability of rolling a number less than 3 is 1/3.
Now we find 1/3 of 420.
1/3 * 420 = 420/3 = 140
Answer: 140 times

Answer: P(Quarter & Penny): 9/100
p(Two pennies): 9/25
Step-by-step explanation:
There are 20 coins in the bag, so you have a 3/20 chance of getting a quarter, 5/20 chances of getting a dime and 12/20 chance of getting a penny on each draw if the coins are always replaced.
Im this situation, you can simplify the fractions, the
Multiply the chance of each independent event times the chance of the next independent event.
3/20 × 3/5 = 9/100 for the quarter and the penny
3/5 × 3/5 = 9/25 for the two pennies
Elena and jada are going home. Elena runs at a constant speed of 4 miles per hour, and jada walks at a constant speed of 2 miles per hour. How far will each one be after 1.5
hours
Answer:
Elena will run 6 miles in 1.5 hours
Jada will walk 3 miles in 1.5 hours
Step-by-step explanation:
Multiply: 4*1.5=6 (Elena's)
Multiply:2*1.5=3 (Jada's)
Elena will run 6 miles in 1.5 hours
Jada will walk 3 miles in 1.5 hours

Part B: How many cubic centimeters of fluid can fill this cylinder? Express your answer in terms of π. options are: 112 pi cm, 110 pi cm, 113 pi cm, 107 pi cm.
Part C: Give a decimal approximation of your answer to the second question using 3.14 to approximate π. options are: 351.68 cm, 368.15 cm, 386.51 cm, 315.68 cm.
Answer: A.) The area of the base is 16 pi cm²,
B.) The number of cubic centimeters is 112 pi cm³
C.) The volume is 351.68 cm³
